Despite their great potential for individualization, 3D-printing processes for polymer parts like SLS (Selective Laser Sintering) and FDM (Fused Deposition Modeling) have the particular disadvantage of a high surface roughness; therefore, surface finishing is often necessary. However, current finishing procedures often have deficits such as low flexibility, long process times or incorporation of abrasives in the component. Therefore, Fraunhofer ILT is developing a non-contact, laser-based polishing process for additively manufactured plastic components.

The enabling technologies for 3D Printing like laser metal fusion, laser metal deposition, selective laser sintering, wire arc additive manufacturing, thermal spraying and electron beam melting need process gases to achieve the quality, finish and mechanical properties desired.

The three companies are cooperating to develop integral solutions for materials, printers, technology and service for 3D printing that can be tailored to meet individual customer needs. Continue reading “BASF, LSS and Farsoon develop solutions for 3D-parts printed by selective laser sintering”
Sintratec launched their SLS desktop 3D printer on Indiegogo back in November. Selective laser sintering is completely foreign to desktop 3D printing, and certainly hasn’t been anywhere near affordable. Sintratec, whose printer goes by the same name, changed all this when they offered the world’s first desktop SLS printer for under $4,000.

Tests have shown that the Digital Light Processing (DLP) based technology developed by the Energy research Centre of the Netherlands (ECN) and its partners, for the 3D printing of ceramic materials can also be made suitable for metals, which will be, and I quote: ‘providing a higher-quality alternative to existing 3D metal-shaping techniques.’ Continue reading “Breakthrough: Digital Light Processing For Metals”
