This was way too cool not to print.
Update - 10/20/2015 - Time lapse video added. See all 4 pieces printed in hi-res time lapse. Neato!
It printed great. Although I think the middle and top piece can be joined and printed as one piece and support would still not be needed. At 35.mm layer height the mask is very sturdy with no loss in detail. (using a .6mm E3D Volcano hotend)
All parts were printed in PLA @ 190-195 degrees on unheated glass with hairspray (except the visor which had a very small footprint relative to height so a blue tape & hairspray combination was used
The printer is custom built based on the now obsolete gMax 1.5 but with significant feature and firmware enhancements.
.6mm E3D Volcano hotend
.35 layer height
40 mm/sec print speeds
2 loop perimeter
1st layer @ 40% speed
1st Layer @ 250 width
1st layer @ 100% height
2 loop brim with zero offset(for the first layer only)
Total print time:
14 hrs 46 min
Print times per piece:
Bottom: 2 hrs 48 min
Middle: 5 hrs 32 min
Top: 4 hrs 57 min
Visor:1 hr 29 min
The next print I'll join the top and middle pieces and also print the entire mask in one print. All of the parts will fit on the bed. I didn't know how this would turn out so I printed them individually. Next one will be one print.
