![]() ![]() The technology utilizes a mirror that is programmed to direct an ultraviolet laser to draw and cure a part's cross-section onto a vat of photopolymer resin. Stereolithography (SLA) is known for achieving highly detailed and functionally accurate parts. This process is ideal for functional testing, in the low to mid volumes (10s to 100s of units). Selective Laser Sintering (SLS) uses high-powered lasers to sinter powdered material, binding it together to create a solid structure. ![]() Machines range from hobbiest-grade to professional grade. Objects are produced layer by layer using a variety of different materials and layer adhesion technologies.ģD printing has evolved significantly over the decades and over time many different technologies have been developed:įused Deposition Modeling (FDM) is a common process for early stage prototypes. 3D Printing, or additive manufacturing, is a process that utilizes a CAD file (typically an STL) to produce a 3-dimensional part.
