Quad Color Printing

4-Color Self-Portrait by br3ttb

Not only is br3ttb an OpenSCAD Challenge Imaginary Prize Winner, but he’s also doing some crazy amazing stuff by printing in FOUR colors.  Similar to the printing processes of old, br3ttb set down one color at a time on top of another to form a four-color picture, using just one extruder.  The result is a very lightly textured and posterized version of br3ttb’s own portrait.  In the true spirit of Thingiverse, he has shared lots of information about his software toolpath1 and design process so you can try it out yourself.

I’m also reminded of a recent Thingiverse contribution from RichRap where he achieved a similar effect by cutting and joining different colored filaments and then printing a model that would reveal different colors at different heights.

I suppose if you had an apparatus that could select, cut, join, and feed filaments in conjunction with a LOT of custom firmware and GCode, you could print in 8 bit color!

I needed a new profile image. While I'm proud of the project that lead to my former "TV face" image, it didn't really say "Thingiverse" Having just successfully created a 3 color bottle opener, I knew the time for a multi-color portrait had come. This is my first attempt at mashing colors together on the same layer like this. I'm really happy with the results. Hopefully others will take this technique and run with it. Turns out you don't need dual extruders to make a multi-colored part! tv-face: brettbeauregard.com/blog/tag/hdtv-mount/ 3 color opener: brettbeauregard.com/blog/2011/09/three-color-3d-print/

This was an experiment using some great coloured Faberdashery PLA filament. It was not just designed to look pretty as I added lots of sections for filament bridging and thin layers for colour change. Skeinforge finds bridging on curves hard as it decided on an angle for the direction of bridge and does the whole section the same angle, so at points along the curve filament is going straight into the gap, this makes it a hard test especially when done at high speed, that’s why you can see a few gaps and dips in the model surface. I could make it look much better with a different Rainbow design but this was testing how the filament would perform on my Prusa Mendel ‘Bling’ machine.

Ed Tekeian’s Action Figures Are Awesome!


I saw these action figures pop up on the internet and I had to interview Ed to find out more!

Can you explain the grant you got and why it inspired you to make action figures on a MakerBot?

The Cambridge Center of Adult Education is exploring the idea of producing art in the model of sustainable agriculture. It’s called CSArt. People buy shares in nine artists and recieve 3 pieces per delivery, over a two month period. CSArt encourages artists to think about their work in a small business context. In return, shareholders get access to a wide range of artists at a fair price.

When the grant was announced last June, I had just returned from my visit to the BotCave and was really charged up. I was convinced the MakerBot would be a great tool for artists. It was only a matter of time before I was all-in. The CSArt grant came up at the perfect time. It gave me the opportunity to adapt my work into mass customization without giving up the hands-on aspects of making art. Price barriers makes it hard for people to access original art. This is one of the key ideas in CSArt and in my approach to making art. The low cost of production on the MakerBot makes the end product very accessible. The work I produced is a series, but, not a set of “signed and numbered” reproductions. The MakerBot enabled mass customization as a practical artists’ tool.

What was your process like? Please walk us through it from idea, to design to object. I’m curious about the survey, too.
I used a Thing-O-Maticwith ABP and the beta of Rhino3D on the mac. I assembled and tuned the MakerBot over a five week period, starting in mid-June.My original idea was a model kit, like the tiny anime robot kits from Japan. I learned about design vs print by developing a prototype form, heavily influenced by Kaiju movies of the 60s. I printed a lot of variations and thought about print-to-print variations, what designs work best raftless and efficient post-printing assembly. In the end, I decided to produce the action figures as kits of parts that I would assemble. For this first series, I wanted to ensure the end result met my standards. I also settled on the idea of mechanical men who carry tools and do heavy work. The one exception is a variant inspired by the works of HP Lovecraft, droids and the octopus on Thingiverse (I love the tentacles).I spent June through early July building the ToM, then prototyped until mid August. I did a test run of the final forms on Labor Day and production through the second week of September. I designed and printed accessories during the third week of September, with two days of assembly and packaging at the end. The MakerBot performance was excellent. I couldn’t have been as efficient without the ABP, Print-O-Matic and the memory card.I decided to start the project with an on-line survey to the shareholders. I wanted to introduce myself and get the shareholders involved from the start of the project. Here is a sample question:

If you had to pick, which of the following would be your most prized possession?
(a) magic ring; (b) lucky pliers; (c) a never-miss hammer; (d) a pencil that promotes worldwide literacy.

95% of the shareholders participated and reported they enjoyed the survey. The packaging of the action figures includes a QR code to the survey results.



What are your plans going forward? What’s next?

I’m very excited about more action figures — so many ideas came up during the summer. I want to look at small groups of figures presented in a scene. I’d really like to create another large series and show them as a group.

Thanks Ed! I love the focus on tool carrying action figures. Ed’s put Robot Toy #A up on Thingiverse for your MakerBotting pleasure.

Chrysler Building by jwolee

Personally, I will not be happy until most of the world’s architectural marvels are available for download and printing at Thingiverse.  So of course I was extremely happy to check my favorite building New York off the list: the Chrysler Building.  While the famous crown ornament, the literal and figurative high point of Art Deco, doesn’t shine quite as brightly in ABS plastic, we’re still very happy to have it as a printable model on Thingiverse.  Thanks, jwolee!

I'm starting to get a little ambitious with my 3D printing now that the new Print-O-Matic settings make the printer do beautiful things. One thing I've kept wanting to try is create large objects by printing it in parts. I haven't really used my printer yet for large prints since in the past I had not been confident in it enough to waste the time and effort if the print was going to fail. But like I've said, I'm starting to get ambitious. Anyway, off to Google 3D Warehouse again, and I found the perfect item, the Chrysler Building. After that was done, I loaded it up into Netfabb to use it's slicing feature. I probably should learn how to do this in Blender 3D properly, but Netfabb makes it so easy. Literally drag a scroll bar, hit Cut, then Export. The size of my model ended being about 320mm tall, and knowing my MakerBot can print about 105mm max, I decided to go safe and cut it into 4 pieces, each one about 80mm tall. Included are the 4 pieces, although the full model is available for you if you want to choose different places to slice. Go to my blog to see how I sliced and diced at blog.fox-lee.com/?p=66
