3D Printed Westinghouse Brake Distributer & Roevac Vents
I've had the latest prints back from Shapeways of my Westinghouse Brake distributer and Roevac vents and I'm slightly underwhelmed by them. I'm sure that I have had prints in the past where I have seen details that are 0.2mm in diameter which don't appear to have come out on these. Perhaps when they are cleaned and primed they will look better? This is the problem with Shapeways - massively variable results!
4mm Westinghouse Brake Distributers:
You can just about see the detail on the distributers in this photo (e.g. the star pattern on top) but screw details are lacking.
Roe-vac vents in 4mm and 7mm:
7mm Roe-vacs:
PTA Wagon Underframe components (including Westinghouse brake distibuters) v0.3. This is one of the better prints, for some reason the brake distributers are much crisper on this print than the other model where 18 have been placed on a cube-shaped sprue:
And for reference, here are renders of the 3D files:
None of the screw detail on the Roevacs came out in either 4mm or 7mm even though each screw in 7mm is 0.3mm wide and 0.2mm high (within the parameters for "surface detail" in FUD and therefore should come out?
