Stereolithography
form of 3D printing technology used for creating models, prototypes, patterns, and production of parts in a layer by layer fashion using photopolymerization, a process by which light causes chains of molecules to link, forming polymers.
Atmosphere Control Unit: Houses the equipment to filter gas recirculated from the process chamber, Maintains a set temperature
SLA
Materials: Liquid, Photopolymer
Components: Laser source/beam, table, wiper, vat, platform, elevator, lenses, sweeper
FDM
Components: Hot end, print display, extruder, filament, cooling fan, print bed
Materials: Nylon, ABS, PC, Ultem
SLS
SLS is a process which uses laser selectively to trace the surface of powder and sinters the material together
SLS is divided into 3 areas: computer/control, atmosphere control and process chamber
Process Chamber: Optics and scanning mirrors are used to focus a CO2 laser beam onto the part cylinder
