【摘要】 Stratasys' new F3300 fused deposition modelling (FDM) 3D printer can now be pre-ordered from Tri-Tech 3D, with shipping scheduled for Q2 of 2024. According to the company, the 3D printer can print up to twice as fast as alternative printers, while offering significant improvements in cost per part and reliability. Featuring four print heads and easy-to-recycle spools, the machine allows operators to preload and print in different materials and colours to achieve a high-quality end product. Its tool changer allows operators to switch between the four print heads, while a heated chamber allows for multi-resolution and multicolour while improving mechanical properties. Operators can also adjust the print speed and layer height to produce parts with intricate details. Furthermore, advanced software means that the machine fills voids in a way that allows for higher part density, resulting in stronger parts. "Because the machine features four material chambers, operators can print large parts without having to stop to reload the material spools," explained Rob Pitts, sales manager at Tri-Tech 3D. "The spool size and design means users can save 25% of their material cost. Coupled with significantly faster printing times and reduced downtime, you can expect to achieve 45% lower cost per part."

【标题】NEW TECHNOLOGY MITIGATES THE COST OF RECOATING ON BUILD TIME AND ENCHANCES ADDITIVE MANUFACTURING PRODUCTIVITY
【参考中译】新技术降低了重建时间的成本并提高了额外的工作效率
【摘要】 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.
