SLS 3D Printer

SLS Printing uses selective CO₂ laser sintering technology which sinters plastic powders(ceramic or metal powders with binding agent) into solid cross-sections layer by layer until a three-dimensional part is built. Before making the parts, need to fill the build chamber with nitrogen and rise the chamber temperature. When the temperature is ready, a computer controlled CO₂ laser selectively fuses powdered materials by tracing cross-sections of the part on the surface of a powder bed and then a new coat of materiel is applied for the new layer. The working platform of the powder bed will go one layer down and then the roller will pave a new layer of the powder and the laser will selectively sinter the cross-sections of the parts. Repeat the process until the parts completed

ZRapid Tech using fast, efficient and agile selective laser sintering technology. Challenged the manufacturing of complex geometric shape of light plastic parts successfully. This technology suits for durable parts or complex functional parts. It's an optimal solution for high temperature resistance or corrosion resistance mold.
