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.

An interview with professor Franz Haas about Selective LED-based melting

sledm

His team has developed a new technology for 3D metal printing and has now applied for a patent. This new technology uses LED instead of laser sources for the additive manufacturing of metal parts and optimizes 3D metal printing in terms of construction time, metal powder consumption, equipment costs and post-processing effort.

Printing multi-hardness parts with SLS – Presented by Maxime Legrand, Sirris

Maxime Legrand, Sirris, will speak at 3D Printing Materials Conference on April 16, during the 3D Printing Event at Brightlands Chemelot Campus in The Netherlands.

New materials are emerging in SLS 3D printing. How to make the best of it? In this presentation, we will consider TPU printing with SLS and how it is possible to change its mechanical properties through parameters optimization and lattice structures.

Post-processing of SLS nylon materials – Presented by Daphne Laméris, Shapeways

Post-processing of SLS nylon materials – Presented by Daphne Laméris, Shapeways, at the 3D Printing Materials Conference, on April 17, 2018, at Brightlands Chemelot Campus, Geleen, The Netherlands. Read the interview

Once a SLS printer is finished, the production is not. The post-processing of 3D printed models has some unique challenges. In this presentation those challenges as well as solutions applied by Shapeways will be discussed.

‘Laser Sintering of Multimaterial Parts’ by Johannes Lohn, Direct Manufacturing Research Center (DMRC)

Johannes Lohn of Direct Manufacturing Research Center (DMRC) presents at the 3D Printing Materials Conference: “Laser Sintering of Multimaterial Parts”. Conventionally, Multimaterial Parts are produced by multi-component injection molding or by assembling of single parts.

Laser Sintering 3D Printer, Sintratec, Reaches CrowdFunding Goal, Announces New Materials

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.
