What do you think, which is stronger? FDM printed (PLA) or SLA printed (Resin) bolt and screw nut? That's what I am testing in this video. Strengh test of PLA bolt as most common material for FDM 3D printer and Water Washable Photopolymer resin. Since I don't have SLA 3D printer, I used 3D printing service, I ordered resin M6x20 bolts and M6 nuts.
