3D Systems DMP Factory 350

Powder (SLS, SLM…):

• SLS: Selective Laser Sintering (SLS) materials are supplied in powdered forms. During the manufacturing process these powders are fused by a pulsed laser beam. This allows creation of durable parts with complicated geometries and can be used to obtain early prototypes, wind tunnel models or casting patterns. Resulting parts have porous surfaces, but this can be fixed with finishing if needed. SLS is rather expensive, as it is necessary to maintain strict temperatures throughout fabrication phases. SLS is used for prototyping and small batch production of functional plastic parts with good mechanical properties.
• SLM / DMLS – DMLS/SLM or direct metal laser sintering differs from SLS mostly by the ability to control the porous properties of produced parts as the material is not burning fused but rather melted into homogeneous structures. SMLS/SLM produces high performance, end-use metal 3D printed parts for applications in aerospace, automotive, industrial and medical. Selective Laser Melting (SLM) Selective Laser Melting (SLM) uses a laser to scan and selectively fuse metal powder particles, bonding them together layer-by-layer.
