We've used 3D printed plastic parts in surprisingly (to us, anyway) rigorous applications. We've used printed PLA parts as prototype bearing holders on seriously high speed rotating equipment. Strength is usually close to fiber reinforced Delrin or similar plastics. 3D printing let us try and tune successive iterations for best performance far more rapidly than we could have done with classical subtractive machining. OTOH, our 3D printers care about the room temperature and HVAC breeze, whereas a lathe or mill wouldn't notice. Tradeoffs.... |
