Case Study: Regional Technological Institute achieves 64% weight reduction and improved milling performance with Altair HyperWorks

Altair solutions reduce weight Of a 3d-printed milling head

Regional Technological Institute (RTI), affiliated with the University of West Bohemia, set out to redesign a steel milling head to reduce moving-part weight, improve reliability and cooling, lower energy use, and allow refurbishment, with production planned via direct metal laser sintering (DMLS). Working with Advanced Engineering s.r.o., RTI used the Altair HyperWorks platform — including Altair HyperStudy, OptiStruct, Radioss, HyperView and HyperGraph — to validate printed steel properties, explore topology and lattice options, and assess impact performance.

Altair enabled a complete workflow of material validation, topology optimization, virtual impact testing and post‑processing that yielded a DMLS-ready, topologically optimized milling head. The Altair-driven solution reduced weight by 64%, improved dynamic behavior for faster milling, enhanced internal cooling to extend tool life, lowered operational energy consumption, and produced a patentable design available for licensing.
