Metal 3D Printing and Framebuilding

[bushtrucker]

All Provas are TIG welded so I’d assume that extra Ti collar on the print is so he doesn’t have to use as much/any filler when welding. Discussed in the post below.

Welding 3D printed titanium

The little fusion rings help out a lot for welding. I have been playing around with the best dimensions. It’s a bit tricky because those fusion rings are often printed as unsupported overhang. This leaves a “broken edge”. Which is fine because it gets melted. But in general, its best practice to minimize print defects because they could have an impact on the mechanical properties. So far for the CS yoke, we are at a 1mm thick lip that sticks out 1.3mm [image] I think it could be a bit bigger…
