Acrylonitrile butadiene styrene (ABS) is a widely available thermoplastic. You can usually find them in legos.
While continuing my test of materials on OtherMill, this time, I decided to try ABS. The material is pretty soft, and can be milled easily. Unfortunately I could not find a block of ABS, so I printed one on a Mojo (much to the dismay of many).
I created a design for a Maze on Adobe illustrator, exported it into a DXF file, and extruded it into a 3D model, and made a GCODE file out of it.
Fixturing an object on the OtherMill can become tedious of the surfaces are not flat. Since my block of ABS was printed, it was quite flat and, only using double sided tape and a bracket with some fastners did the trick. The entire milling process took about 29 minutes (OtherPlan has a tendency to lie when it displays the milling time, because it said about 42 minutes).
I only have the video of how the milling ended (because a 30 minutes long video is what we want but not what we need)
Clearly, the machine can be very messy. But that’s why it needs to be closed while using.
Above is the final ABS maze. Below are images of the finished product.
