ABS: Three Plastics in One

It would be really hard to go through a typical day in the developed world without running across something made from ABS plastic. It’s literally all over the place, from toothbrush handles to refrigerator interiors to car dashboards to computer keyboards. Many houses are plumbed with pipes extruded from ABS, and it lives in rolls next to millions of 3D-printers, loved and hated by those who use and misuse it. And in the form of LEGO bricks, it lurks on carpets in the dark rooms of children around the world, ready to puncture the bare feet of their parents.

Experimenting With Extruded Elements

Conventional 3D printing and other additive manufacturing methods are highly effective at producing parts of irregular geometries that are difficult or impossible to create with other methods. However, there is a whole set of compromises that come with it – material uniformity, strength, and size are just some that come to mind. There are, however, other techniques that can be used in conjunction with these technologies, and the use of so-called “extruded elements” may be one of them.

The idea is to break up large models into a series of smaller mutually interlocking pieces of an extruded form. This is …read more
