Adventures in 3D Printing


It’s been awhile since I blogged about my experiences in 3D printing. Several months ago I found out a close friend of my family (and one of my son’s godparents) would be going away to Seminary to become an Anglican priest. Since he had been such a big part of both my wife and son’s life, I thought he should get something personal from us as a going away present. and since he was also the Organist and Choirmaster of our Church, I wanted to get something good.

Our Church has, in my opinion, a rather nice Sacred Heart Statue in the Sanctuary, and I thought it would be a nice gift to have a small replica made of it. The statue itself is quite detailed, and looks like some sort of Victorian Era sculpture or some sort of similar knock-off style. Apparently made locally here in Winnipeg. Compared with other photos I have seen of Sacred Heart Statues, it is quite nice. So nice in fact, I was pretty certain that an exact copy would be beyond my meager 3D skills, but I thought it would be a good learning experience. I also thought it would be an appropriate reminder of our Church, St Michael and All Angels, while our friend Andrew was away at Seminary. I also thought that I had at least two years to figure out how to do it. Plenty of time.

Famous last words.

Turns out Andrew took some summer session University courses to get enough credits to get into Seminary a whole lot faster. I suddenly went from having years to only a couple of months! And to make it worse, I would be doing most of the modeling during Lent when the statue would be covered up for a good part of the time. I had to rely on some incomplete photo reference. And that the model probably wouldn’t be a completely faithful reproduction.

This was the best reference I had. This three-quarter view shows lots of detail, but a profile and front view would have been better.

After gathering what reference material I could, I set up a file using
Blender. It was the 3D program I was most familiar with and I felt that the program’s sculpting tools would get the job done.

I started modeling the core body first. I feel this is the part of the model that is most accurate to the original sculpture. It started out as a cylinder that I then applied a few basic transforms to get closer the the type of folds I needed. Then I used the sculpting tools to add the necessary details. The arms were fairly easy to make and the hands I borrowed from a free 3D model I found on the’Net. The face was actually pretty easy for me as I already had some experience modelling the human face.


The chausable* was another story. Getting the folds correctly was proving difficult, and I was running out of time. I knew Blender had a clothing simulator, and after going through a tutorial online (thank God for YouTube!) I settled on using the clothsim to help me with the folds.

By this time, I had Andrew’s fairwell date. I only had one shot to make this work. Normally, I would have printed the model out in a cheap plastic or resin to make certain that my model was working the way it should. Even though I was working with a 3D program, I am only ever really seeing a two dimensional representation on the screen. The only way I would know for certain everything was fine would be to see it as a proper object in real life. Since I had settled on a raw bronze metal, I wouldn’t have the time to print out a plastic test model first. So I ordered the metal print on Shapeways

I settled on a raw bronze as I knew that the material would age over time and form a patina. Anyone who has watched antique shows or any of those pawn broker shows on A&E knows patinas are a good thing, and I thought the patina would add some character should my model prove to be slightly sub standard. I also thought the rough texture of the bronze might hide a lot of flaws as well.

When the 3D print arrived I was was generally quite happy with it. There was one flaw with one of the hands though. While it was in the proper position, it was a litle too twisted in one direction. Not a deal breaker, but it would have to be addressed should I ever make the model available for printing for the general public. As for the patina, only time will tell, but in certain light, you can already see a slight green tinge appearing. The renders in this post are simulations of how I imagine the model looking after several decades of use.


I learned a lot while modeling this piece. I intend to return to this piece again once I have gained some more skill in using the sculpting tools in Blender. Maybe I will be able to get a closer resemblance to the original and maybe not rely on a clothing simulator.

Cool Threads

For years and years, I had heard of a website called Threadless. They are a crowd-sourced site for t-shirt designs (among other things). There’s pretty descent cash prizes for the winners and they do seem to have quite a variety of very different styles of designs that get to be printed. After viewing many other designer’s submissions, I decided to sign up.

And then I promptly did nothing about it.

Not too long ago, I decided to give it another try. This time do more than just think about joining in and actually do something about it. I noticed they had a sub contest where they wanted character submissions and these character submissions (if won for t-shirt design) would get created as a vinyl toy! With my burgeon experience in 3D printing, I thought I’d have the advantage of knowing what might translate well into a proper three dimensional design. So here’s my design:


I know a lot of aspiring designers and artists follow my blog, so if you are of a mind, and think my design is worth it, follow the link, and give me a vote! Act soon as voting will end in a few days. You’ll need to either set up an account with Threadless or sign in using Facebook to vote though.

And even if you don’t think much of my design, go to the site anyways and check it out. There’s a lot of clever imagery there that might just inspire you to make a design of your own! Or perhaps pick up a tee or two for yourself!


The Case for a Really Great Case


For Father’s Day this year I was treated with an iPad Mini with Retina display. White with 32 gigs of storage. Why 32 gigs? It’s pretty much the same price as the 16 gig iPad Air I bought for my wife on Mother’s day.

This meant I was in the market for a new case.

I have a BookBook cover for my iPhone but I was unhappy with the build quality. After a couple of months of use, the colour on the outside quickly wore away. Though the case has mostly survived the year and a bit that I have owned it. I originally wanted that type of case as it came with a side wallet. I find it great for storing business cards (either mine or someone else’s) or other bits of papers or things i pick up throughout my day. Despite being a pretty early adopter of the iDevices as PDAs I still have a habit of scribbling things down on random scraps of paper.


I heard about the cases for Pad and Quill a while ago and thought about checking them out. They definitely had the style of case I was interested in, but they were pricey (and rightly so). After checking out Amazon for similarly stled cases i decided that:

A) There are quite a few cases out there that are only synthetic leather even when you use genuine leather as a search term.

B) My balking at the price was mainly my own cheapness as comparable cases were mostly similar in price. At least as far as the iPad mini is concerned. I still find Pad and Quill’s iPhone and iPad Air cases a bit too pricey.

So I decided on the Graduate series as there were a few personalizing options in terms of colour I was interested in and I didn’t need all the fancy folding options for media watching as I am still fond of the giant screen in my living room. And until now, I typed all my blog posts on my phone, so a much larger virtual keyboard is more than enough for me. So no need for a bluetooth keyboard or more fancy folding options for me! And of course, the price was right for cheap little old me!

I entered in all my info online and was pleasantly surprised when my order arrived just a few short days later. And to top it off, I didn’t have to deal with any hidden extra fees couriers like FedEx like to extort Canadians when packages cross borders. When pacakages need to go through customs, the couriers will charge a fee to act as an agent on your behalf. This can sometimes be as much or more than the package is actually worth! There are ways around it, but it is still a hassle.


The case itself came neatly wrapped with a wax seal. Very nice touch! And the case itself is beautiful! Just like an old fashioned book. A nice slate grey material with red accents for the outside, and a nice deep red interior. and birch inlay that holds the iPad perfectly, though the opening for the power switch is a bit off. I imagine that may be due to the fact this case is good for the iPad Mini with Retina display and the previous model that came without? The button is still visible though so not all is lost.


So far I am loving the case. and it is meeting my needs. The write up on the website had this to say about the Graduate:

It just feels … well, right. Of course, the Graduate iPad mini case is not a time machine, but once you feel the bindery cover, you can’t help but reminisce about the old university library stacks. How you’ll use the Graduate is up to you – hold it, fold it or prop it.

I never went to university, but I did grow up spending many hours pooring over my set of encyclopedias (rememer those?) and I’d say the feel is as good, if not better than those cherished old books.


My only concern is the elastic that keeps the faux book closed might one day break. I know Pad and Quill offers a repair service, but I’d rather not have to go to such lengths and I am hoping to be able to use this case for a long, long time. I dont like being on the technology rat race so I don’t always have the latest greatest. I hopefully won’t need a new iPad for at least a few years, and as long as there isn’t a drastic form change, hopefully, future iPads will be able to fit this case with maybe a few shims to help stay in place.

All in all, a great case for a good price. Enjoy. [Pad and Quill Handmade Graduate Edition hard case for iPad mini Blue/Slate]

A Designer’s Guide to Flexo Printing – Part IV


This is part of a multi-post story on flexography for the designer. You can read more of my previous posts on the subject here, here, and here.


Registration is a big problem with flexo printing. But there are quite a few things you can do as a designer to help mitigate the problem of your colours not lining up once on press.

Heavy Traps

Flexo presses typically have much greater trap lines to help with registration. Trap sizes will vary depending on the type of press, but I have seen everything from .5 pt (not too bad – similar to screen printing and some newsprint) to 1.5 pt or more! Heavier traps will have an impact on your line widths, the details you can have in your design and the type of colours you choose for your design. As an example, printing a blue object next to a yellow object will result in a very noticeable green trap line where the two colours meet up. This may obscure small type and details.

Cyan type on yellow background. It may stand out, but if this is fairly small type, this will be an issue to trap.

Here are two options to trap. One is to spread the cyan into the background. Makes a nice green. And is hard to read the type.

Or we add a black trap line to hide everything.

Or we add a black trap line to hide everything.

Another bad example occurs when blue and red are printing side-by-side. It isn’t too bad when the traps are small, but it gets pretty ugly once you get into larger traps. Having Complimentary Colours trapping to each other can be a real problem. Complimentary colours will always create ugly greyshish/brownish colours when they overlap. Good colour combinations to trap together would be yellows, reds and oranges, or greens and yellows. Blues and purples aren’t as good a choice, as I will get into next, but they work as well. Black lines can be your friend to hide unsightly trap lines, but your design may wind up looking like a kid’s colouring book if you are not too careful. Or try to keep the colours as separate as possible. No need to worry about ugly trap lines if your colours do not need to trap!

Getting out of Reverse

One big problem with bad registration is reverse type or graphics. Small type reversing out of process colour can sometimes be hard enough to reproduce when printing standard offset printing. Keeping your reverse type legible in flexo can be a nightmare. Best to avoid this altogether, but if you must, try to choose a nice open san-serif font. Serif type will fill in otherwise. And the fewer CMYK components your background colour is, the better. Reversing out of one or two colours is much easier than three or four. And check with your printer, you might be able to sub in a spot colour which will make reversing your type or other graphics better. You will also have to make certain your line widths are nice and thick. Quarter point rules reversed out of any background colour will fill in. Your printer should have information for you on just what line thicknesses you can use for reversing out of colour. Be prepared for minimum line thicknesses of 1.5 pts. or more though.

Reversing out of all process colours can be a problem with small type or graphics.

Colour Jogging

Colours that touch each other that are similar to each other in their process colour breaks can be a joy or a pain to reproduce. Take blues for example. Nice, pure blues are usually made up of combinations of cyan and magenta. If both cyan and magenta changes for each touching colour, there can be a “double image” printing effect. Seeing double may work fine for a night out at the bar, but not so much when reading the ingredients or other small type on your packaging. Only changing one of the components (like the magenta) and leaving the other one that same will greatly reduce this problem. See the illustration for a clearer example.

Colour type where multiple colours change can result in "fuzzy" type or graphics.

Here, only the magenta changes. When the type goes out of register (bottom image) you cannot tell at all!

Hold lines.

Printing process colours that have been surrounded with white can be a real problem. If a colour is made up of two or more components, you can get a double image or “fuzzy” type and graphics. The fewer the components, the better. Using all four process colours is a real bad idea. Three is better, but two is ideal. Red and greens are the most forgiving, blues and purples are not great. If you have complex colours that require a lot of different process colour components, try using a spot colour instead.

If you are using process colours in this way, you may find a hold line will help you out. A hold line is an outline of colour that only uses one process colour to act as a hedge against mis-registration. If you are printing a blue colour made up of cyan and magenta, try a cyan only outline around the object. The line thickness is usually half the trap amount. This way, if the colours mis-register (and they will) the cyan outline will prevent the magenta from peeking outside the cyan, creating nice ugly, unwanted, pink shapes. See the illustrations for some examples.

A hold line in action. When the magenta goes out of registration, the hold line helps control the damage done.

Image of the Month – May 2014


Whew! May was a petty busy month. This image was orginally going to be submitted to the @Sketch_Dailies twitter feed, but I decided against it last minute. It just wasn’t working for me. I let it sit for a while and then re-tackled it. It really didn’t take much re-work at all. Sometimes you just need some time to distance yourself from your work in order to see it for what it really is.

This is a mix of traditional pen and ink drawing with some colour added in both Photoshop and SketchBookPro.
