3D printing service
3D printing technology is a collective term for a series of rapid prototyping technologies, the basic principle of which is laminated manufacturing. 3d printing service providers will use a computer-aided design model to produce a three-dimensional object. 3D printing service includes 3d design and printing services, 3d laser printing services, 3d model printing services, 3d plastic printing services, 3d prototyping service or 3d rapid prototyping services, etc. SLA printing service and SLS printing service and SLM printing service are three common types of 3d model printing services.
SLS Selective laser sintering
SLS is an additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal or polymer), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. It is similar to direct metal laser sintering (DMLS).
SLM (Selective Laser Melting)
SLM represents elective laser melting, a kind of additive manufacturing, metal powder rapid prototyping technology, which can directly form metal parts that are close to full density and good mechanical properties. SLM technology overcomes the complicated process of manufacturing metal parts by Selective Laser Sintering (SLS) technology
SLA（StereoLithography）
SLA means laser curing rapid prototyping technology, the process of molding is to dip the photosensitive resin liquid through the workbench, and then irradiate the liquid surface by ultraviolet light, and the irradiated part is immediately solidified and formed.
