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.

Continuous fiber 3D printing allows producing fixtures, spare parts and functional prototypes which are several times stronger and lighter than plastics and metals. There are 2 types of continuous fiber 3D printing, they both have pros and cons. To take the best from both Composite Fiber Co-extrusion technology was developed. Use cases will be shown.

Presentation / interview with César Stüpp, Brightlands Materials Center / TNO.

Fused filament fabrication (FFF) is a very versatile AM technique, although it is widely used for prototyping due to their limited mechanical properties, especially in between layers. To approach this matter, a novel technique was developed in which the strength in between layers was increased in 184%, which results in stronger parts.

New technology revolutionizes 3D metal printing, LED instead of laser or electron beam

sledm

Graz University of Technology has developed a technology that 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. Selective LED-based melting (SLEDM) – i.e. the targeted melting of metal powder using high-power LED light sources – is the name of the new technology that a team led by Franz Haas, head of the Institute of Production Engineering at TU Graz, has developed for 3D metal printing and has now applied for a patent.
