Prototyping

Here is a description of my recent experiences building a 3D printer and getting it up and running, for those that might be interested in this technology.

Includes my first print results which turned out to have surprisingly good accuracy (although needing some tweaking to get things "printable"). Good accuracy? I can not measure the variation from 90º on my printed parts, all axes combinations. Dimensional tolerances are on the order of 0.7 mm., all three axes. At least half of this can be attributed to material shrinkage during cooling. Improving surface quality will most likely improve tolerances significantly. Coming soon - tweaking my 3D printer for improved print quality.
