Looking at building a second printer, first was a prusa i3

aim: faster, more accurate and bit bigger print diameter (300mm round), and be able to print nylon

So i’m thinking of building a delta with square linear rail, a steel frame, and a e3d hot end, 5mm thick build plate

Im thinking about trying to weld the frame (tig welding) i know its not easy to keep things square when welding, but i figure if i use big box section and just a few tack’s i should be able to stop welding when it is and still have heaps of weld to keep it super stiff) has anyone done this before? or brazed may be a much easer option.

Would like to make something as fast as the DeltaWASP 20 40 Turbo, and so stiff that i get very good accuracy.

Also what should i use a smoothieboard rather than a t based controller to get to the speeds i would like!?

IMHO: You don’t need to weld unless your going to be walking on it.

Don’t weld it. It’s crazy difficult to weld with accuracy needed for a 3d printer.

Yeah, welding sounds cool and all, but really makes no sense for this application.

I agree with Stephanie. I like screws because they can be loosened and adjusted (or completely taken apart). I have a Delta similar to what you described and I plan on future changes too. The flexibility is why I made a Delta in the first place.

Smoothieboard is the best for a delta printer!
