Document Summary
The production of physical prototypes with very short lead time. Essentially from cad drawing to part in a few hours. Also known as 3d printing or desktop manufacturing. The ability to fabricate components without specialized tooling such as patterns or dies. Same as rp, only not prototypes but actual parts for use. Additive: keep adding material to produce nal part. Then, the model is converted to a . stl le format, and most of the 3d drawing packages will perform this function: virtually slice into layers. The part is sliced into successive layers, each of the same thickness. Ballistic particle: droplets of material that solidi es and builds up. 3d printing (binder) and sls (laser sintering or particles) In the stereolithography (sla) process a uv or laser curing resin is used. Then, platform is lowered into the resin to a depth that a thin layer of resin is on top of it.
