How durable are objects made with a 3D printer?
3D printing resins - HD hard vary wildly in strength - some are extremely fragile (early acrylate resins), some are as strong as injection molded polymers like ABS but more vulnerable to ultraviolet light damage, becoming brittle with prolonged exposure (newer acrylate and epoxy based SLA resins).
3D printed object parts can actually be stronger than the same material produced by casting. Testing shows they can achieve performance equaling or exceeding forged components with proper stress relieving heat treatments and hot isostatic pressing.
the3d printing technology (Fused Deposition Modeling (FDM) vs.Stereolithography (SLA) vs. SLS, etc). Can you please narrow it down a bit to a specific set of criteria like temperature, pressure, load that needs to be handled, budget, size, etc.
