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.

“Material Development for Fused Deposition Modeling”, Presented by Martin Faber, Applied Polymer Innovations/ Innofil3D

Optimization of the material properties of filaments is an essential factor in broadening the applicability and increasing the ease of use of fused deposition modeling (FDM). It is necessary to understand how the materials behave during heating and cooling in a FDM 3D printer. During this session important aspects of the material properties and their influence on the printing behavior will be explained.

Helios One 3D Printer – New Heliolithography Technology Could Eventually Replace SLA and FDM

When it comes to consumer level 3D printers, there are 2 types of technology currently available. There is fused deposition modeling (FDM) and there is stereolithography (SLA). The former creates 3D objects by melting plastic and extruding it onto a print bed, one layer at a time.
