Luckily for [Austin], many of the gears in the Printo appeared to be identical. That meant he had several intact examples to base his 3D models on, and with some educated guesses, was able to determine what the missing gears would have looked like. Coming from an animation background, he...
Therefore, the made-in-house filaments had enough mechanical strength to withstand the forces applied by the feeding gears without fracture. In agreement with other authors [36,44], the incorporation of the plasticizers (TEC or sorbitol) into the formulation of the filaments contributed to the ...
