  1. Version 1.0


    I printed this for my niece. Please note: it has been sanded smooth with 320 sandpaper.

  3. It depends on the colour. I find the natural white ABS pro gives a much better print quality and it is tolerant of fan cooling to a point. ABS Pro has a FANTASTIC sanding surface if you start with 180 paper and end off with 400. ABS pro is as good as the Ultimaker light blue PLA filament. I often sand items smooth and paint them. Cover the front of the UM2 (cardboard). Partially cover top with wide strips of paper that have the edges folded for stiffness. It is not a fully enclosed volume and there is enough room for the head to move around. It is however more than enough to keep it toasty in
  4. Whoops. I meant ETHYL Acetate and not Acetyl Acetate.
  5. Yes, you can use ETHYL Acetate to smooth PLA in much the same manner as acetone will smooth ABS. However, ETHYL Acetate on PLA might not meet your requirement to hold maximum detail. ETHYL Acetate will eventually melt PLA. Nail polish removers contain acetyl acetate. For smoothing, I've tried paint-on products like XTC 3D with variable results. It seems to be less work to paint a glaze on (vs. vapour) and with practice you can directly control how much detail you want to retain in complicated areas. However an absolute requirement for XTC 3D is a method of properly clamping your object so you

    3D Printing experimental composite. I printed the frame in black ABS on my Ultimaker 2 in a collaboration with a knife maker John Arnold. The yellow is epoxy and the scales were machined and finished by John to the knife frame. Knife Gallery I was after a clean, razor-sharp contrast between yellow and black that can't currently be obtained using dual extruder heads. I normally vacuum-infuse epoxy into 3D prints to drastically increase overall strength and stiffness (water-tight hydraulic fittings and other engineering applications), but it was used in this way for a striking, alternative loo
  7. Try Acetyl Acetate instead with PLA. It smooths PLA plastics like acetone.
