designing parts for 3d printing



what i'm going to explain now is how we goabout building parts larger than what our build envelope is. our largest build envelopeis 36 by 24 by 36. this bumper here was built in two sections. what we did is in our softwarewe were able to go in and split it and put a dovetail in it, and a dovetail helps holdthe part together and gives it an index so that it lines up properly. we process thefile, it gets sent out to the machine, it's


designing parts for 3d printing, built, it goes to finishing, and at that point,they will weld it together. so first, we'll line up the dovetails, tackthe welds on the weld bearing points. the reason we do the tack welding first is toavoid any warping. after you do that, you'll go and fill in all the seams. so this is aplastic weld. it's a plastic solvent cement,


and we'll just use that to fill in the backside of the part. what i'll do is i'll just grind this seam down here, and then afterwe sand it down, we can use heat to bring the color back, and hope it'll look a littlemore finished.

we have done multiple large parts. the largestthat i've seen since we've been here has been a sixteen foot full size landing gear assemblythat was built in approximately 40 pieces and, when assembled, was extremely accurate.it was used to test hydraulic fittings for a full size landing gear assembly.
