One million diode lasers to replace injection molding

EOS presents its new LaserProFusion technology at Formnext

According to EOS, it is a process that can revolutionize the production of plastic parts: At Formnext, the company has introduced its LaserProFusion technology for polymer additive manufacturing: with nearly one million diode lasers melting the material, building up the part layer by layer, this build process is so productive that it can serve as an injection molding alternative for many applications.

Furthermore, EOS presents the latest EOS M 300-4 system as foundation of a production cell for serial additive manufacturing with metal materials. In addition, the company introduces Technology Readiness Level (TRL) in both the field of metals and polymers, which will provide additional clarity on the maturity of materials and processes.

new level of productivity

Dr. Tobias Abeln, Chief Technical Officer (CTO) at EOS says: »With the LaserProFusion technology, we are achieving a new level of productivity in polymer industrial 3D printing for serial manufacturing. It is a technology that can be an alternative to injection molding in many applications, respectively enables tool-free injection molding. This will make industrial 3D printing attractive for a completely new market in the future.«

Instead of the laser sintering process used to date with a single CO2-laser moving along the entire build area, this new technology uses up to one million lasers. These can achieve a maximum total output of up to 5 kilowatts. For each layer, only the diode lasers are activated that match the CAD data of the part – right down to the exact pixel. The new technology significantly shortens exposure times, regardless of the number of parts and their geometry.
