Renishaw to Unveil LIBERTAS: Redefining Productivity and Precision in Metal AM
Renishaw, a leader in precision engineering and additive manufacturing (AM), will unveil its latest AM innovations at the upcoming Formnext 2025 Expo, taking place from November 18 to 21 in Frankfurt, Germany. Renishaw will present a production-focused showcase under the theme: “From Print to Precision: Productivity Upgraded.”, showcasing high-productivity additive manufacturing workflows for diverse applications including the production of microturbines for propulsion and energy generation.
Precise Tuning of Laser Parameters
At the heart of the showcase is LIBERTAS, Renishaw’s new software that opens unprecedented access to laser parameter tuning. LIBERTAS addresses two of the most persistent challenges in metal AM: poor downskin surface finish and the need for support structures. While traditional supports manage heat and distortion, they increase material usage, extend build times and require costly post-processing.
Unlike conventional workflows, LIBERTAS dynamically adjusts scan parameters across different sections of a part, enabling engineers to print complex geometries with smoother downskin surfaces and without supports. This also results in reduced waste and higher-quality finishes, maximising AM’s productivity without the need for costly hardware upgrades.
“Traditionally, support structures are required for surfaces with a critical angle of 45 degrees or more from the horizontal. With the Support Reduction Package, this threshold has been extended—reducing the critical angle to as little as 5 degrees in certain cases,” explains Benjamin Díaz, Additive Manufacturing Product Manager at Renishaw Ibérica. “Beyond reducing support requirements, this approach also enhances surface finish and mitigates thermal stress by intelligently regulating energy distribution during the build process.”
“Visitors will see a complete production cell featuring a Renishaw RenAM 500 Ultra system with TEMPUS technology, a Chiron Micro 5XL and Renishaw’s new Equator-X dual-method gauging system, providing an end-to-end process flow: printing, milling and inspection”, said Chris Dimery, Additive Manufacturing EMEA Business Manager at Renishaw. “On this cell, there will be a nozzle guided vane (NVG), enabled by LIBERTAS, the Chiron machining critical features, and the Equator-X system performing part inspection. This illustrates a practical workflow that builds upon Renishaw’s advance manufacturing knowledge, showing users what is possible when you work with the right partner.”
Renishaw will also feature advanced microturbines from Argive, a recent spin-off of UK metal manufacturing specialists Alloyed, showcasing the potential of AM for high-performance propulsion applications. The A300 microturbine is already incorporated in drone applications, whilst the A1100 microturbine is additively manufactured using Alloyed’s nickel superalloy ABD-900AM, which is engineered for high-temperature performance and durability.
“To complement our on-stand production cell, Renishaw will present alongside Siemens Digital Industries Software in a joint session to showcase a fully integrated additive manufacturing workflow designed to deliver optimised, integrated blade rotors for aerospace and defence applications,” added Dimery. “Using Siemens’ digital twin technologies combined with Renishaw’s precision metal AM systems, advanced toolpaths and post-process metrology. The session will demonstrate a seamless, data-driven pathway from digital design intent to certifiable parts for next-generation platforms.”
