Selective laser sintering makes use of a CO2 laser that fuses nylon-based powder, layer by layer until final thermoplastic parts are built. Stereolithography makes use of high precision machining an ultraviolet laser that attracts on the surface of liquid thermoset resin to create hundreds of skinny layers until final parts are fashioned. Get a practical snapshot of the surface finishes which might be} possible on machined plastic and metal parts. This information contains high-quality photos of your surface end choices at Protolabs. Geometries could be built more easily outcome of} 3D printing process, adding complexity without extra cost.
