one mold's part left
Mold for left tube holder/longeron:
stepper motor sleeve / ceramic bearing holder. Extrusion of PVA filament is tricky. Filament needs to keep dry – In Vancouver it is hard – as a result needs to cut “spaghetti” 10-25 m long. Estimation of required length in 3D printing software kind of sketchy. Mistake in manual measurement can ether ruin part or extruder can stop thread's extrusion. Loosing part better then stops – PVA in extruder coagulates if left for a long time under 190C. Video capture and remote desktop essential in this case – from cellular phone it is possible to do check process remotely. Safety is mandatory also – nobody knows what happen if experimental technology will generate sparks. Pictures in last posts was not captured intentionally but rather as a "side effect" of 3D printing process. Even with all of printer’s problems it is not comparable with time savings.
