Additive manufacturing 3D printing
A great challenge for 3D printing, FDM process, is the stability, more precisely, the tensile strength of the printed 3D object in the Z axial direction. PeroLab nano particles worked into plastics, e.g. PLA, make it possible to heat up the plastic filament immediately using lasers or with LED lamp radiation. In 3D printing, the filament layer put down after the nozzle is radiated at the same time with a laser or LED lamp. The contact surface of both layers heats up immediately and fusion is guaranteed. This achieves a secure, stable connection of the layers. Tension rod measurements revealed an increase in tensile strength in the Z axial direction of up to 80 %.
