I just printed this.
Used MatterHackers' pro series red PLA and standard series gold PLA. I'll probably sand and paint it with rustoleum eventually, but I like the way the gold looks right now. Its semi-translucent, so you can see the infill pattern (picture doesn't really capture this). Red pieces were printed on an Ultimaker 2 at 0.1 mm layers, and the gold ones were done on a WASP 40 70 at 0.2 mm layers. I estimate the total print time at about 120 hours. It took so long because of the fine layers, which really weren't necessary.
Most of it is held together with superglue, however there was not really a good surface for this between the top and middle red pieces. I ended up using a soldering iron on low heat to weld them together on the inside.
The default scaling is a little small, imo. I printed it at 100% and I can't get it on without removing the jaw. I do not have a large head. Once inside, though, its pretty roomy. I take this as incentive to add servos for the jaw and faceplate.
The faceplate does not fit on perfectly around the top. I suspect that the WASP was not really calibrated well. My plan is to warm it up a little past the glass transition temperature of PLA (about 65 C), then bend it into the right shape and use tape to hold it there while it cools down.
Also threw together a quick arc reactor by cutting the outline out of aluminium foil and putting it in front of an EL panel.
Lastly, this is my first post. Hi Everyone!
