Faster Laser Powder Bed Fusion: 3D Printing While Recoating | Formnext 2023

Renishaw's "Tempus" technology is an improvement to its laser powder bed fusion metal 3D printing system achieved entirely through a control algorithm. Instead of laser melting and recoating of the powder bed being separate steps at each layer, the Tempus system combines them. Melting happens while the recoater arm moves. The algorithm simply accounts for the position of the recoater arm at every moment. The result, as seen in this video, is laser melting occuring both ahead of and behind the movement of the recoater. Reduction in build time varies with geometry, with the greatest percentage reduction seen in builds where the laser time and recoat time are relatively balanced.

So simple and elegant, it is puzzling nobody did it before

Just like an interrupter gear of propeller fighters - brilliant!

What's next? De-powdering the lower layers while the upper ones are still being printed?

More e more fast, and accurate, the Industry never be the same again....CNC machines becoming pat away
