Stereolithography printing
SLA is based on the process of photopolymerization. SLA resin 3D printers employ laser rays to convert or cure the liquid resin into hard plastic. Parts manufactured through SLA printing are sharp-edged, and have a smooth surface finish with minimally visible layer lines. The SLA technology has widespread applications, including product design, medicine, jewelry, model making, education, engineering, and more

Selective laser sintering SLS 3D printing uses a high-powered laser to fuse small particles of polymer powder. This printing technology is ideal for products with interior features, undercuts, thin walls but with complex geometries. The unfused powder gives added support to the part during the printing process. SLS is preferred for functional prototyping and suitable for economical delivery for bridge manufacturing or short-run injection molding.

SLS for Composite 3D Printing
SLS, an advanced additive technology uses a laser to fuse powdered materials such as
polymers, and metals, layer upon layer to create 3D objects. The powder can be a combination of TPEs, TPUs, or nylon depending upon the characteristics required in the final product. EOS SLS technology is an all powerful solution that allows for the production of critical and complex functional parts using varied composite materials.

DMLS for 3D Metal Printing
DMLS is preferred for serial manufacturing of 3d metal parts for many industries. The major applications of DMLS 3D printing are medical, automotive, tools, turbomachinery and aerospace. EOS is a major global provider of DMLS.
