Care & Finishing of
3D Printed Parts
The 3D printed parts that I am providing are all printed in ABS, otherwise known as Styrene. It behaves in a manner that is very similar to the HIPS (High ImPact Styrene) sheet material that I cut my CNC parts packages from. (see the WikiPedia article for more information). The primary difference is that I have discovered is that ABS dissolves in Acetone alone as well as Methelyene Chloride based solvents while HIPS only dissolves in a Methylene Chloride based solvent (typically Weldon #3). Otherwise, as noted below, you can finish the two materials the same way.Infill
is a set of Utility Arms Being Printed. There's enough plastic on all
of the outside surfaces to allow for the typical amount of
priming/filling/sanding/painting process used with your other styrene
Things to be concerned about:
When clamping parts take care as a C clamp can easily exert enough pressure on one point to crush a part.
The Pivot hole is sized for a 1/4 inch shaft. While you can drill it out for a large size, say 3/8, that would expose the fill lattice and weaken the part. If you want to use a larger size shaft, ask for a custom version (there's no charge for the customization!)

part with and without brim.
What you can't see in the views above, but is obvious from the photo to the left, is that the part without brim became detached before the print completed.
Brim is easy to remove. Just use a sharp knife, or other tool of your choice, and follow the part contour. If I have to use Brim on a part it will be on the end that is typically hidden.
