Simufact Engineering, an MSC Software company, has released Simufact Additive 2, a new version of its simulation solution for metal-based additive manufacturing. The software provides a series of capabilities covering powder bed fusion processes that deliver more certainty in achieving a reliable additive manufacturing process for high quality parts.
New capabilities include:
Calibrating with cantilevers – a fast optimization algorithm calibrates the inherent strain values. These strain values represent the machine, the material as well as the used process parameters and provide for reliable simulation for complex additive components.
Individual positioning of parts in virtual build space – provides for the efficient positioning of parts on the base plate and allows for iteration to optimize the build-up orientation. Positioning the part is very intuitive, due to the easy to use interface.
Support of orthotropic material properties – which enables a more realistic representation of support structures stiffness. Coarser meshing provides reliable results with a simultaneous reduction of the required calculation times.
Optimization of the additive process chain – an effective, fast optimization of the whole process chain. The user often simulates several variants, which differ. Each process step can be optimized separately based in the previous results.
Simulate HIP processes – densification of components can be simulated. This process reduces porosity and provides longer life to products.
Comparison with physical testing – Enables comparison of simulated parts with the target design or 3D measurement data as a reference. Simulated deformations can be evaluated relative to the reference geometry.
“For the technical heart of the software we developed an application-specific solver based on MSC’s powerful generic Marc solver. Simufact Additive will be able to capture the complete process chain in the manufacturing environment and to scale the simulation based on the user requirements. The key driver is accuracy followed by speed. Therefore, we have developed a completely new infrastructure specially dedicated to AM.” – Dr. Hendrik Schafstall, CTO Simufact
