Open Collab – Typo Session

Open Collab is a experiment in digital collaboration. Throughout the month they put out an open call for submissions on a theme that are the randomly combined with other submissions to create new works of art. This month it was the Typographic Session and they asked participants “to test, showcase and challenge your freshly designed fonts…This session the format is 1200×480px. Using your self-designed font, please try to find a word, that fills the format as good as possible. Feel free to use any language. The result will not only be a beautiful composition of fonts, but also a (hopefully) funny piece of 3-word-dada-poetry.

How to participate

  1. Create a 1200×480px artboard
  2. Adjust the fontsize to the height of the artboard
  3. Find a word, that approximately fills the width
  4. Do not leave margins – they will be added automatically
  5. Export as jpg
  6. Submit work

Best practice

  • JPG: black type, white bg
  • Single line of type
  • Try different color modes” (Open Collab 2021)

With that in mind I created my word “Inner” from my recent Tuscan experiment and submitted it. You can see it below combined with other submissions.

This was a fun experiment to be part of and was a good reason to start producing designs with my components.

Animating the Logo

Reflecting on the concepts that underpin the design of a logo, Graphic Designer Adrian Shaughnessy in his book Graphic design : A User’s Manual (2009, p.181) notes that “a logo will have to work on numerous platforms, mobile phone screen, website, T-shirt, and at the end of a television commercial. Increasingly, too, logos have to move. The days of the static unchanging logo have gone. Today our logos are expected to be mini movies that tell us stories.” It is this idea of combining movement with the logo to help convey meaning that I wish to explore. When creating my branding it was with the intent that it’s forms would be simpIe and flexible enough to be able to be animated in a variety of ways to further reinforce the key themes of the brand, exploration, accessibility and unexpectedness. The high contrast forms should remain distinct even when manipulated and warped.

Shaughnessy finishes his reflection on logo design by saying the “final development in logo design that designers have to take into consideration is that the era of the monolithic, unchanging logo is over. In our visual culture we want variety and stimulus. Accordingly, the logos of the future are likely to be ever changing and malleable.”. For an author writing in 2009 this has been particularly prescient as you can see this malleability being apparent in much contemporary branding, for instance in Monotypes branding work for Amsteldok as shown below.

Amsteldok Branding (Monotype 2020)

This makes use of a variable typeface at it’s core to create a system of interrelated letterforms that warp and move in relation to each other.

Previously, in my professional career I have created animations using After Effects, however I found this program to be too complex for the simpler style of animation I was looking to achieve. Instead I looked at using Adobe Animate, a vector based animation program that has a powerful suite of tools suitable to the animation and manipulating of letterforms. Having never used the software, I worked through a series of tutorials that are included with the program and created the animated pencil gif to the above right. Once I felt comfortable with the software, I experimented with some basic styles of revealing letters in the logo as seen to the right. I wanted to play with the idea of different parts of the logo revealing themselves as they are explored. There are still many things to correct, for instance the timing of the reveals and the quality of the movement, but it is an avenue I hope to continue to explore further as the project develops.

Above. My initial test animation for the ODD Foundry logo. The timing needs to be corrected as well as the removal of some thin outlines that not meant to be appearing over the logo.

Above. My amended test animation. I have altered the timings at which areas of the logo are revealed.

Different Tools for Making Letterforms

As I seek to formilise the tools I will create as part of my project I have undertaken research into how different tools and methods can be used to create letterforms.

The work of illustrator Alyn Smith is defined by the creations of his own tools for mark making. These range from silicone stamps to stencils. He has created his visual language initially around shapes that have an imperfect, hand cut element to them. The tools he has created allow him to continue to explore that language in a different medium.

Lustig is a typeface produced for Hamilton Wood Type by Lustig and Cohen that is formed through the strict adherence to a custom grid. The curves, distances between strokes and heights of letters are all defined by the shape of this grid.

Shape Grammars is a book by Jannis Maroscheck and is described as “a dictionary of 150,000 shapes and systems” in an interview by Ayla Angelos (2020). The shapes within were created by running 12 different algorithms through a computer resulting in “a 836-page study into automation in design”. The resulting forms are abstract shapes that when presented as a set of shapes encourage the eye to explore and our brain to understand, are the letterforms or are they purely shapes? Maroscheck comments that while “the computer is quick at drawing…the machine is mindlessly executing a ruleset with some random variation…It is limited; it can never escape a system’s given logic.” This rings true to a quote from a calligrapher, Paul Standard, as quoted in the fy{T}i newsletter (2021) that states “Geometry can produce legible letters, but art alone makes them beautiful . Art begins where geometry ends, and imparts to letters a character transcending mere measurement.”

Goertek (KONTRAPUNKT 2021) 

The typeface Goertek by KONTRAPUNKT (2021) is a sound reactive typeface which has been designed to have stroke widths and components that warp and respond to sound. The result is a typeface that is in a state of flux, mirroring its surroundings and making it’s context integral to the forms in which it presents itself.

Perception of Letterforms – The Brain and Gestalt Theory

My project focuses on the development of western letterforms based on latin alphabets. In the 2014 documentary about her by Edward Tufte, Inge Druckrey posits that “the classical Roman letter is the ancestor of all later formal developments of our alphabet.” From these original letters you can trace a direct connection from what we see as the latin alphabet to the progression into formalising these letterforms via mechanically reproducible typefaces. Druckrey believes the connection between the hand and tool, and of the marks it makes on the paper are important in understanding letterforms, that since the “letter was originally written. The written letter is a memory of motion.” Before we can write, we can draw. So to understand this movement and the way we perceive these marks we can look to the act of drawing.

To draw is not too simply make marks on a substrate with a tool, there is intent in the meaning produced by the drawing of the marks. In his book Drawing On The Right Side Of The Brain (2013, p.18) Edwards explores how the human brain perceives forms. The concepts he explores are primarily linked to drawing skills, believing that the skill “is basic to training visual perception and is therefore the entry-level subject —the ABCs—of perceptual skill-building.”(p.18). The low economic barrier of entry and availability of the materials allows anyone, of any skill or age, to become learned in the process. However in outlining the series of five subskills needed Edwards realised they “were not drawing skills in the usual sense; they were rock-bottom, fundamental seeing skills: how to perceive edges, spaces, relationship, lights and shadows, and the gestalt. As with the ABCs of reading, these were the skills you had to have in order to draw any subject.”(p.10).

At its most basic a letterform is made of a combination of black strokes, arranged together in varying weights and angles. But alongside seeing the black of the letter, we also see the internal white space that these strokes encapsulate, as well as the strokes interaction with the space around it. This white space is called negative space. Where the negative space meets a stroke it creates an edge, Edwards believes “In drawing, the term edge has a special meaning, different from its ordinary definition as a border or outline. In drawing, an edge is where two things come together, and the line that depicts the shared edge is called a contour line. A contour line is always the border of two things simultaneously—that is, a shared edge.”(p.151). This concept of an edge or boundary is further explored by Martin, Buskist and Carlson in their book Psychology where they discuss our perceptions of forms, stating that “one of the most important aspects of form perception is the existence of a boundary. If the visual field contains a sharp and distinct change in brightness, colour or tex­ture, we perceive an edge. If this edge forms a continuous boundary, we will probably perceive the space enclosed by the boundary as a figure”

So to perceive a shape as a letterform we first see it as a combination of strokes and space, joined by edges. We must next recognise that combination of shapes and space as being related to our pre-existing notion of the different letterforms that make up our alphabet. One of the exercises that Edwards instructs his students to do is to draw a portrait from memory and then to analyse the work, commenting that drawing from memory “brings forth a memorized set of symbols, practiced over and over during childhood… by countless repetitions.” (p.52). This set of childhood symbols seems very applicable to our understanding of a shape as a letterform. In order to write language we must first learn how to make marks, then shapes. Finally we learn to write a letter through the repeated practicing of a series of these fundamental shapes.

The act of recognition relates to the idea of an objects gestalt. Edwards believes gestalt “emerges as comprehension of the thing itself or the thingness of the thing, resulting from intense focus on the parts that make up the whole, and the whole, which is greater than the sum of its parts.”(p.31).

The theory of gestalt was first outlined by German Psychologist, Max Wertheimer. In his lecture about the subject, David Hogue, describes how when Wertheimer’s viewed a theatre marque covered in lights that “a series of blinking lights creates the illusion of motion.”(2018). Even though it is just the individual lights turning on and off in sequence, our brain perceives it as being one illumination that moves from light to light. This interaction highlights two of the key laws of Gestalt; the Law of Figure-Ground, that our brain can perceive foreground objects as different from background objects, and the Law of Simplicity in which our brain seeks to “organize our perceptions into the simplest possible experience. We will interpret ambiguous, vague, or complex objects in the simplest way possible, because it is faster and easier to perceive things in a simple rather than complex way”.

These laws further inform other principles relating to our perceptions of form. The most relevant ones to the understanding of letterforms as words are the principle of Proximity where “objects near one another in space or time are perceived as being a group and belonging together”. This can very easily apply to the grouping of letters into words, sentences and paragraphs. The next is the principle of Similarity which states “that objects with similar characteristics, such as form, color, size, and brightness, are perceived as belonging together.” So for a series of letterforms to be perceived as either a word or, in a more abstract way, a typeface the repeated characteristics in them must be similar (ie similar stroke width, use of angles etc).

Print Room Tests

With lockdown lifting I have been able to get access to the print room to finally see how my test blocks print. First impressions are very promising, the surface takes ink very well and transfers the design to the paper without slurring or marring the design. When printed next to conventional type made of wood and metal they are the correct height and the quality of the printed design is comparable if not impossible to identify as being a different material. After a day of printing they appear to be in much the same state as when I started with no sign of compression . They also clean easily with Lincoln wash and white spirit without the printing surface being affected (some materials fog and become textured when exposed to a solvent).

Initial blocks – Angle and flat printed blocks.

The flat printed blocks produced a successful print with an even distribution of ink. The angle printed blocks however appeared to show signs of compression with the printing surface being slightly lower than the other flat printed blocks. When locked up against other blocks it also becomes evident that they are also not square, seeminly having shifted slightly during the 3d priting process. Finally the actually print surface, due to being made up of many layers of resin rather than one flat layer as on the flat printed blocks retains ink when cleaned and prints with a slightly textured finish. Overall the flat printed method appears to produce the most consistent results.

Registration circles

After printing a few different variations of the 3 circles, which have been designed to test registration, there is a noticeable misalignment between layers. Close observation of the blocks when printing indicates that due to the slightly flared bases of the blocks, the elephants foot effect as mentioned previously, when pushed next to each other the blocks do not sit flat on the bed of the proofing press. Instead they tilt side to side. I will need to work out a way to negate or minimise this flaring in order to create blocks that will produce accurate prints.

Typefaces With Meaning

When a written message is read by a viewer they deconstruct the various components and structure of it in order to decipher the intended meaning of the author. In his book on the subject of semiotics, This Means This, This Means That, author Sean Hall outlines that at its most basic this structure is made up of both syntax and semantics(2007).  “The syntax of language tells us when a sentence has been constructed in a fashion that is grammatically correct and when it has been constructed in a way that isn’t. Semantics, on the other hand, is about what the sentences we construct by using various grammatical rules actually mean.”(p.93). However when a written message is included in a graphic composition it communicates not just via the content provided (ie. what is written) but also via how it is written (ie. what is the chosen typeface, what colours are used, where is it placed within the composition?). As author Meg Miller states “for typographers, letterforms are also tools, giving form to words, which can then be used to convey meaning, to signify, indicate, express, and conjure up ideas.” (2021). These additional factors can heavily influence our understanding of the meaning being communicated. Within the study of language this would be considered the connotation and denotation of a message (Hall p.118).

In her book Why Fonts Matter author and designer Sarah Hyndman (2016) posits that a designers choice of typeface can help imbue a piece of work with meaning and help the readers in many ways. One of which is helping us choose between different options. In the example below “typefaces help you to decide who you would trust to do a professional job for you. For example, which of these three lawyers would you hire?” (p.18)

Font choice (Sarah Hyndman 2016)

It is evident that certain typefaces and type classifications bring with themselves additional cultural meaning and denote different things. “Many professions have recognisable typeface conventions, especially established industries where the preference is likely to be for traditional, conservative and relatively neutral typefaces that suggest history. Often these have links to Roman inscriptions, engravings or ancient manuscripts that give the impression of longevity and wisdom.”(p.57). I would argue that an understanding of the original meaning behind these conventions (in this case Roman inscriptions) is less important for the reader in denoting further meaning from a piece than a cultural awareness of other contemporary relevant uses of the designs, in this example the understanding that lawyers make use of serif fonts similar to that used in the above example.

Professor of Art, Edmund Feldman, devised a 4 step method for analysing art work that I believe can also be applied to the reading and understanding of a typeface.

As quoted from the Galveston ISD article about the subject (2021), the 4 steps are:

“DESCRIPTION What can be seen in the artwork?

ANALYSIS What relationships exist with what is seen?

INTERPRETATION What is the content or meaning, based on steps 1 and 2?

JUDGEMENT What is your evaluation of the work, based on steps1, 2, 3?”

I feel the Feldman technique is helpful for slowing down and reinforcing each stage of the reading of a piece of work, with the 4 steps being split between connotation (description and analysis) and denotation (interpretation and judgement).

Alzheimer Nederland Poster (Studio Dumbar 2021)
Alzheimer Nederland Promotional Pack (Studio Dumbar 2021)

The branding by Studio Dumbar for Alzheimer Nederland (2021) makes use of a custom designed typeface to reinforce the meaning and work of the organisation. The typeface is of a sans serif geometric style, the stroke widths remain consistent throughout each letter but the central space of each letter is removed (description). The position and amount of space removed from the letter changes depending on the letter so that the overall form of the letter can still be perceived. The use of the typeface across a whole word allows the user to read the content easier as our brain uses the context of the word to mentally fill in any letters that are hard to discern (analysis). The process that the reader goes through in trying to understand what is written in the typeface is similar to that of a person having Alzheimer’s themselves and the degradation of the letterforms reflects the degenerative nature of the disease (interpretation). Based on this analysis I feel this typeface successfully communicates the intended meaning of the design, while also being a striking and recognisable design element (judgement).

The modular typeface, Baker (2021), was designed by Fontself to commemorate the death of Gilbert Baker, LBGTQ+ activist and the creator of the iconic Rainbow Flag. Fontself have taken their design cues from the stripes of the flag and created a series of interlinked components that flow and create each letter form. These components are all unified in their use of angles and widths, creating a diverse selection of shapes that are all recognisable as one unified whole. This reflects the inclusive and diverse nature that the Rainbow flag represents.

On the theme of community and diversity, the Diversity Type project from Distillery (2021) creates unity out of disparate letterforms by unifying them with colour, size and position on the page to ensure that the content is read a word rather than a series of letters.

Diversity Type Project (Distillery 2021)


In general, legibility is key to the communication of meaning. Without being able to discern the letterforms of a word then meaning can be lost. However, designer Sam Barclay flips our perceptions of legibility in his book I Wonder What It’s Like to be Dyslexic (2014). The book, made of various essays around the subject utilisise layout, colour and typefaces to communicate to the reader the many difficulties that a dyslexic person may encounter. The image here is of a double page spread set in the Can You Read Me font, a font made by Phil Baines (1995) to test our perception of each letter.

Anatomy of a Letter

Fig 1. Anatomy of a Typeface
Fig 2. Similar letterforms apparent across multiple typefaces

As shown above in fig 1, different letters are made up of different components. In general a letter will be made of the same components, though the style of these components may change depending on the design of the typeface and its classification, as you can see from fig 2. Indeed it is this collection of definable components from letter to letter that define it as being able to be identified as the letter in question.

Fig 3. Root forms of letters

Within the alphabet there are various letters which have visual similarities to one another, the design of these letters often informs the design of other similar letters. How closely linked these similar letters will be in the design of their letterforms will be based on the learned eye of the type designer when they construct the typeface. A letter needs to be distinct from another similar letter whilst still being stylistically similar to the rest of the typeface.

When analysing a typeface you can find various recurring forms, with the design of one component informing another with regards to how a line terminates, how sharp a curve is and thick a stroke should be. This internal set of rules is defined by the type designer and it is what makes a letterform be recognisable as part of a typeface rather than being a disparate letterform.

Fig 4. Recurring forms

Broadly typefaces can be divided into two styles, Serif and Sans Serif. In his book on the subject, typographer Bringhurst says a serif is a is simply defined as a “stroke added to the beginning or end of one of the main strokes of a letter. In the roman alphabet, serifs are usually reflexive finishing strokes, forming unilateral or bilateral stops. (They are unilateral if they project only to one side of the main stroke, like the serifs at the head of T and the foot of L, and bilateral if they project to both sides, like the serifs at the foot of T and the head of L.) Transitive serifs-smooth: entry or exit strokes – are usual in italic.”. But there is much historical and stylistic variation within each. In some cases the design of a typefaces individual component can be so distinct it is possible to name the face simply by seeing the component in question. Further expanding on the classfication of serifs, Bringhurst continues by outlining the following terms:

“Abrupt and Adnate Serifs are either abrupt – meaning they break from the stem suddenly at an angle or they are adnate, meaning that they flow smoothly into or out of the stem. In the older typographic literature, adnate serifs are generally described as bracketed.

Bilateral – serifs extending to both sides. There are many descriptive terms for serifs, especially as they have developed in roman faces. They may be not only unilateral or bilateral, but also long or short, thick or thin, pointed or blunt, abrupt or adnate, horizontal or vertical or oblique, tapered, triangular, and so on. In texturas and some frakturs, they are usually scutulate (diamond-shaped), and in some architectural scripts, such as Eaglefeather and Tekton, the serifs are virtually round.” Bringhurst (2004, p.312, p.330)

Discussion with Ryan Molloy

A transcript and audio file of this discussion is available here

I became aware of the work of Ryan Molloy after watching the Letterpress United – Making Type (2020) presentation. A graphic designer, typographer and educator, Ryan presented a series of his experimental typefaces that he designs and cuts using a CNC machine.

What attracted me to Ryans work was his very different perspective on the medium of letterpress printing which I beleive is informed by his background in street art. Much of his personal work shows evidence of the fluid letterforms of graffiti writing (fig 1) which he has then formalised, refined and transferred into his professional work (fig 2).

Fig 1. El Chupo Print (Ryan Molloy 2018).

Fig 2. Arts Cal Poster (Ryan Molloy 2017)

This freedom of movement and experimental approach is also mirrored in his work using letterpress blocks and printing methods. Gblox (fig 3 and fig 4) is a typeface created by cropping into hand drawn letterforms, which are then CNC cut into blocks. The resulting prints merge the non-standard shapes of lettering with the rigid structure of a letterpress print.

Fig 3. Gbloxs (Ryan Molloy 2020)
Fig 4. Gbloxs Print (Ryan Molloy 2020)

With having access to his own router Ryan has been exploring the creation of type that orientates in none standard ways. In my proposal journal I comment that “conventional type for letterpress printing is created to be linear, that is at runs from left to right in a straight line. These type faces are cut into different shaped blocks that interlink to create forms that are normally unheard of within letterpress printing.”

Modular Circular Ornaments (Ryan Molloy 2020)

Some key parts that came out of our discussion were that, like myself and Chris Wilson, Ryan is an educator himself who works with degree equivalent Graphic Design students in the USA. We spoke of the benefits of having access to various tools like CNCs and laser cutters while working as part of a university as well as a desire to be creating new forms of type that push the medium on ward. We discussed how letterpress as a medium will remain attached to 0.918″ being the height of printing blocks until a new style of adjustable press is created that is affordable and accurate enough to replace vintage presses. The part I found most helpful was the understanding that new technologies allow much more freedom and control over the cutting/shaping process. With traditional processes such as pantographs you are limited by the detail of the pattern you use as a template as well as the patience of the operator controlling it. Whereas with a computer controlled CNC the digital pattern can be incredibly detailed due to the high quality modern router tips and the fact that it will be cut via the CNC.

Initial 3D printing tests

I purchased the Mars 2 alongside some further relevant materials. When a print is made it first needs to be cleaned off the excess resin with a relevant liquid (in the case of the water based resin I have purchased this is water), after that the print needs to be cured under ultraviolet light. Some people leave their prints outside to cure in the sun but with the current unpredictable weather and a need for the prints I create to be consistent across a range of prints I opted for a machine that will wash the print as well as cure it.

Elegoo Mars 2. (Elegoo 2021)

Tinkercad

While waiting for the order to arrive I endeavoured to learn more about the 3d design process but setting myself a series of tasks to complete in tinkercad, this was a method I utilised in the Digital Media unit and I found it very helpful to progress through the relevant tasks.

Tinkercad provides various short tutorials on how to create commonly made items. (Tinkercad 2021)

The tasks I set my self to complete were

  • Draw a square
  • Draw a cube
  • Set cube to 1inch x 1inch x 0.918inch (Type Height for letterpress printing)
  • Add letter to cube
  • Hollow cube
  • Support cube
  • Add drainage holes

Mars 2 3D Printer Calibration and Tests

Levelling the print bed of the Mars 2, the white rectangles on the rear of the machine are the extra carbon filters I purchased.

Once the printer arrived there were various assembling and calibrations to be done. Much of this is documented very well in the materials that come with the machine and after levelling the print bed I attempted my first print with the test model provided, a chess piece. While printing this piece I kept the space well ventilated and used gloves while handling resin. After a roughly 2 hours the piece had finished printing successfully and I washed and cured it using the wash/cure unit.

Once dried the models are placed in the Wash/Cure unit and the mode is changed to “cure” along with a timer being set. The machine rotates the models and shines uv light at them.
The final printed model after curing.

Testing the Test print

Structurally the piece is very solid, the resin doesn’t feel brittle and the surface feels relatively smooth to the touch. With being in lock down I have limited tools to test the durability of the print, however it withstood multiple drops onto a concrete floor without shattering which is important for a printing block as they can easily be knocked off a table in a print space.

Print Angles

The test piece was printed flat on the print bed but a technique that is often used for more complex prints is to angle them off the print with a series of thing supports holding the piece in the air. In his video “My favorite way to 3D print perfect resin bases for my minis. Something I discovered printing dice?” (2020), maker 3dprintedpro shows that the reason for this is that apparently when things are printed directly on the print bed they can be hard to remove, with so much of the print being in direct contact with the print bed. When the initial layers are attached to the bed they are intentionally overexposed to create a good adhesion to the print bed, this overexposure can cause a slight variation at the base of the print where the overexposed resin expands slightly. This is colloquially called “elephants foot”. Also for complex prints with overhanging parts when printed flat you run the risk of not it printing incorrectly if not angled and supported in the right manner.

With the print process taking a while and me not having any blocks designed for print yet, I downloaded a selection of coins/tokens/model bases (essentially flat objects with a design on one surface) with which I can experiment with print angles to see which method of printing will work best – flat on the bed or at an angle with supports.

Initial Tests

Angled Designs

I placed a selection of designs on the print bed and varied their angle of elevation, then placed supports around them to connect them to the bed. The prints were successful and similar to the eye, but when viewed closely you could see and feel a stepped pattern across the top surface of the token caused by the angle of the layers being printed. Interestingly prints that were only angled slightly from the print bed had the worst examples of stepping, with it be very pronounced even to the eye.

Flat Designs

Using the same token designs as the last experiment, I printed a selection flat on the print bed. With printing something so shallow the print was completed very quickly (around 25 minutes). However I found that when placed in the wash/cure unit to wash the prints that there was a lot of excess resin. The wash/cure unit cleans the print via creating a whirlpool of water that the print is placed into. Evidently, this doesn’t clean a print sufficiently when the design is shallow and on the print bed. For the next prints I will try cleaning the prints by hand in water with a small scrubbing brush. The quality of the prints was very good but they were very hard to remove from the print bed, to remove a print you lever it off with a metal tool much like a paint scraper. With so much force being exerted upon them, when they did separate from the bed they ricocheted off the cleaning surface and onto the floor, so some means of removing them from the bed needs to be considered if this is the way I choose to print future print.

Printing a Design as Veneers

With the flat design taking so little time to print, and my skills in Tinkercad progressing, I also experimented with printing a selection of thin designs that could be mounted onto a block of material (for instance mdf) to bring them to type height. My research shows that this is something that other printers have done, as shown in the previous post.

Though the print was ready very quicky the resulting prints were so thin that once cured and dry they have warped and curled. I tried heating them in warm water and clamping them to correct this but the prints remained unsuitable for printing.

It is my hope with this project that I can devise a method of production that minimises the amount of post production needed before printing with the blocks. Printing a design as a veneer in this way and then mounting it was always going to have involved accurately cutting and mounting them on to wood. Something that in the current lockdown with minimal access to tools will be very difficult so I will progress with my aims of accurately printing a type height block.

Further 3D Printing Research Based on SWOT

My analysis of the threats and opportunities the medium presents has yielded some questions that I will answer via some further research.

How strong are resin prints? Will they crack if put under pressure?

In the video by the maker Thomas Sanladerer, “Is resin 3D printing worth it?” (2021) he poses a similar question and conducts various forms of research to compare the SLA and FDM print processes. From this research it would appear that when force is applied perpendicular to the direction the layers of the resin that distortion and compression is minimal. The relative hardness and whether a 3d printed block will crack is harder to answer through secondary research as there are many different types of resin with different properties (clear, matt, “plastic like”). I do know, from my own primary research into the letterpress printing process in the proposal stage, that the amount of excess force exerted on a block is low. Metal type and wood type are not hard materials and dent easily, blocks from these materials do not deform or break except if used in an incorrect manner on the press.

New software to learn

After discussions with classmates and relevant technicians at the University, a few different programs were suggested. There are paid options like Autodesk and Sketchup and free versions such as Blender and Tinkercad. The paid options appear to be too extensive for what I aim to produce, being more suited to complex 3D shapes. Tinkercad appears to be able to very quickly produce simple shapes in the correct file type for printing.

How much does the resin smell and are there any safety concerns?

Looking at the various resins available and reading their safety sheets, all would appear to need to be used in well ventilated areas and to use gloves when handling them. Some resins are cleaned with alcohols (either isopropanol or methylated spirits) whilst others are water based and cleaned with water. In the current pandemic isopropanol alcohol has become very expensive which seems to indicate water based is a more economical option. Water based resins also are noted to be low odour. Some models such as the Elegoo Mars 2 pro has a built in carbon filter, Elegoo also produce a rechargeable carbon filtration unit that can be used with any printer (Elegoo 2021). Maker, Uncle Jesse, reviews an integrated Wash/Cure unit produced by Elegoo that appears to make the washing and curing process much easier and cleaner (2020).

How long does a print take?

In order to print a model with a 3D printer the file needs to be sliced into layers via slicing software. Many printers make use of a free slicer called Chitubox, this software also gives an estimate of how long the print will take. I have downloaded and inputted a simple 1 inch cube model created in Tinkercad and the print time is stated as being 1 hour 4 mins. This time would be the same whether you filled the print bed with designs or whether you were just printing one, it would only extend the time if the print was made taller due to the fact the prints are made layer by layer.

How much will a solid block 1inch cubed cost? Will it be uneconomical to do a selection of letters in this way?

Chitubox also allows the user to input the cost of the resin you plan to use and then generate a cost estimate based on the volume the print will use up. A solid 1inch cube is estimated at  £0.76 when using waterbased resin. When 3D printing a large model it is quite common to hollow out the piece to use less material so there maybe a way to do this to minimise the resin used but still create strong prints.

There appears to be various models and makes of printers available, which is the most suitable?

3D printer technology is in a continuous state of improvement, with models of printers being superseded by new models every quarter and old models being discontinued. This has made researching what is the most suitable difficult as review videos quickly go out of date. Most machines are made in China and imported into the UK via the EU so this has also made sourcing a machine difficult. Most commercially available have a similar sized build plate and overall size, the differentiation seems come from the speed of the print and the quality of the LCD screen (3dnatives.com 2021). At the time of writing the brand Elegoo have just released the Mars 2, confusingly this is a newer model than the previous Mars 2 Pro. The Mars 2 appears to be the most suitable, it has a high quality screen with a fast print size. It also has a rubber gasket around the shell to keep fumes inside and space for carbon air filters.
