Laser Powder Bed Fusion
Upscale 3d-printing With Beam-shaping
Beam shaping is a key-enabler of the upscale of Laser Powder Bed Fusion (L-PBF) machines. First, it increases printing speed (x3.3), paving the way for mass production. Second, the possibility of printing new powders by removing hot-cracking and increasing the density, which increases the machine flexibility

CANUNDA-HP for L-PBF
Laser Powder Bed Fusion (L-PBF) is an additive manufacturing process. A high-power continuous-wave laser scans a specific path on a bed of metal powder, melting the metal as it passes. This allows parts to be printed in successive layers. Beam shaping improves the L-PBF process by reducing cracking during solidification and achieve a density over 99.9% without post-processing. It makes it possible the production of parts using Inconel 939, a resilient nickel alloy, on an older-generation machine previously lacking this capability.
The CANUNDA-HP module is a beam shaper designed to handle high-power. Its fully reflective design based on MPLC technology delivers an optimal intensity profile.
Multiple shapes are possible (top-hat, ring, M-shape) with possibility to have a fast by-pass function to get back to the initial Gaussian beam.
However, we also offer customized, flexible solutions to suit a variety of L-PBF requirements (new beam-shapes, different spot sizes, specific mechanical designs …). CANUNDA-HP modules are used for custom static or dynamic high-power continuous-wave laser beam shaping. Each of our products is meticulously tailored to your industrial environment (scanner, L-PBF Machine …), offering seamless compatibility with all types of fiber lasers.
