文摘：Traditionally in laser powder bed fusion (LPBF) the laser will stop firing while the recoater adds a new layer of material. Recoating the build plate typically takes under ten seconds per layer, but with builds often made up of thousands of layers, these delays can add up to tens of hours over an entire build. Increasing the productivity of existing AM systems is key to reducing cost per part. Here, Renishaw has focused on how to boost efficiency by utilising the recoating time. The company realised it could connect its recoater and laser control systems, allowing the lasers to fire while the recoater is moving without the risk of hitting it. This concept led to the development of TEMPUS technology, a software-driven technology that synchronises the laser, recoater and elevator systems, using timing data to optimise the process productivity. As a result, its AM system users gain advanced control of laser positioning and timing, enabling the laser to start firing as soon as the recoater adds a new layer of powder to the target area.
