SLA
Stereolitography
Stereolithography (SLA) is widely recognized as the first 3D printing process; it was certainly the first to be commercialized. SL is a laser-based process that works with photopolymer resins that react with the laser and cure to form a solid in a very precise way to produce very accurate parts. It is a complex process, but simply put, the photopolymer resin is held in a vat with a movable platform inside.

DLP
MovingLight ® DLP
MovingLight ® DLP — is a similar process to stereolithography in that it is a 3D printing process that works with photopolymers. The major difference is the light source. MovingLight ® DLP uses a more conventional light source, such as an arc lamp, with a liquid crystal display panel or a deformable mirror device (DMD), which is applied to the entire surface of the vat of photopolymer resin in a single pass, generally making it faster than SLA.

Direct Metal
Laser sintering and laser melting are interchangeable terms that refer to a laser based 3D printing process that works with powdered materials. The laser is traced across a powder bed of tightly compacted powdered material, according to the 3D data fed to the machine, in the X-Y axes. As the laser interacts with the surface of the powdered material it sinters, or fuses, the particles to each other forming a solid.

SLS
Selective Laser Sintering
SLS or Selective Laser Sintering is the name of the process of creating objects from powders using atomic diffusion to create a 3D object. During SLS technology tiny particles of plastic, ceramic or glass are fused together by heat from a high-power laser to form a solid, three-dimensional object. Objects printed with SLS are made with powder materials, most commonly plastics, such as nylon, which are dispersed in a thin layer...

Polyjet
A 3D printing process whereby the actual build materials (in liquid or molten state) are selectively jetted through multiple jet heads (with others simultaneously jetting support materials). However, the materials tend to be liquid photopolymers, which are cured with a pass of UV light as each layer is deposited. PolyJet materials are capable of manifesting the highest resolution of any 3D printing technology or material.

Micro SLA
As the name of the technology says micro SLA just can print micro or small parts. Micro SLA was developed to produce small, but in other hand with high level of detail. Sometimes bigger doesn't mean high quality, and here micro SLA is an excellent example of that. Some people in our industry are saying that micro SLA machines are “smaller than most coffee makers and faster than baking a cake.”

Plastic Jet
Also known as extrusion printing, Plastic Jet Printing is a 3D printing technology that uses plastic to create 3D printed parts. It’s similar to Fused Deposition Modeling (FDM), but the printers are made for strict dimensional properties. Plastic Jet also doesn’t have a great surface finish – certainly not as good as SLA surface properties. However, it’s still fairly decent compared to other 3D printing technologies like SLS.
