Stereolithography (SLA) is the first additive manufacturing to be ever developed. It is a form of 3D printing technology that uses parabolic mirror ensures that the laser prints perpendicular to the build plane, ensuring uniform print quality across the entire build platform giving the smoothest surface finish available in the market.
SLA technology is a wide ranging solution for standard, engineering, castable wax, and biocompatible 3D printing.
DLP technology is perfect choice for digital manufacturing for Industry-wide compatibility from Jewellery, Dental, and Audiology production.
Digital Light Processing is quite similar with SLA technology but it uses a projector light instead of a single laser and it produce faster output than stereolithography.
Selective laser melting (SLM) is one of the premier technologies in additive manufacturing metal parts utilizing both for rapid prototyping and mass production.
SLM is very similar to SLS, and both processes are covered under the powder bed fusion umbrella.
An SLM machine has a chamber filled with metal powder. This metal powder is then spread across the substrate or build plate in very thin layers by a coater blade.
