HyProCell was represented at the TCT Conference @ Formnext, a world-leading summit that delivers insight from the innovators, facilitators, and champions, shaping the design-to-manufacturing industry. Each year the event brings together internationally-recognised organisations, industry experts, renowned academics and market analysts from Europe, USA, and Asia to provide a truly global overview of how advances in 3D technologies, design, and engineering, are impacting the manufacturing world.
Christian Tenbrock of Fraunhofer ILT delivered his presentation entitled ‘Scalable machine concept for Laser Powder Bed Fusion’.
The presentation explained the successful expansion of Additive Manufacturing in series production, which is contingent on the scalability of the build volume and the productivity of machine systems. In particular, this applies to Laser Powder Bed Fusion (LPBF). Fraunhofer Institute for Laser Technology (ILT) has built a new laboratory system with a very large utilizable build volume (1,000 mm x 800 mm x 500 mm), which is substantially bigger than the commercial LPBF systems used to date. Established inert gas suction strategies of today’s LPBF machines are no longer effective for a very large build volume. Instead, the scientists at Fraunhofer ILT are basing their approach on a movable processing head with a local shielding system, which ensures a constant stream of inert gas at every processing point for build volumes of any size. Furthermore, the processing head is equipped with a compact multi laser-scanner-system to ensure sufficient productivity when manufacturing large parts. As the kinematics of the machine concept differ from conventional LPBF systems, novel manufacturing strategies had to be found and qualified. First manufacturing trials have shown the suitability of the approaches for manufacturing large parts.
