3D printing Space Invaders plugs with silver ABS December 1
Silver Space Invaders detected
I recently bought some silver ABS plastic from the MakerBot store and finally got started printing with it yesterday. Whenever I get a new colour of plastic, I like to 3D print some Space Invaders plugs with it.
Normally I print them in two parts, so that the outside face of the plug is printed “face up” and then attached to the plug piece with a solvent. This time I tried printing each plug as a single piece (“face down”), figuring that I could smooth out the bottom surface afterwards. Here’s how it went:
Compared to a second, untreated, two-piece version:

Keep in mind that close-up photos of 3D printed stuff tends to look rougher than in real life.
I’ve been using acetone and Plastruct Bondene for smoothing and cementing parts for a little while now, and although I’m not totally happy with the single-piece plugs I’m going to do something similar on a new silver blade for the Sword of Omens.

Heh, I’ve got a new platform for my ‘bot that should sort that out, but I don’t want to do any maintenance on it until after my next demo.
