The art and science of "3D printing".(3D space)

The traditional path from design to a working model (that works as envisioned) is strewn with discarded prototypes. Until recently, thai was a painstaking process--even the best-drawn plans of mine and men often need many revisions until the whatchamacallit turns just right inside the thingamajiggy. Now "rapid prototyping"--or "3D printing"--has drastically shortened the path from mind to matter.

Many of the 3D animation creation tools that we have mentioned so far in 3D SPACE let you save files in the STL (short for "stereo lithography") format. When you send that STL
