In laser powder bed fusion additive manufacturing (LPBF-AM) technology, the biggest concern amongst all is that residual stresses are prone to fracture support structures, leading to further exaggerated part distortion. Intelligent support structure design can add benefits such as heat sink, ease of removal, better surface finish, along with basic function of fixtures and datums. Process simulation plays an important role in predicting distortion, structural integrity and residual stresses in the build. XFEM can be applied to simulate the crack initiation and propagation.


In this eSeminar you will learn:

  • How to design intelligent support structures considering part design.
  • Process simulation best practices
  • Applying XFEM to predict potential build cracks during the LPBF-AM process
  • How simulation can guide part orientation and support structure design

The methodology presented is not a simple proof-of-concept but it has been validated with physical print and published in NWC 2019.



  • Support structure design in AM
  • Process planning and virtual printing
  • Predicting build cracks
  • Use of XFEM in virtual printing


Who should attend?

Engineers, team leaders and managers who are exploring additive manufacturing in their organization, Organizations with an interest in different stages involved in AM like developing, designing and manufacturing products, Additive Manufacturing Product Design Engineers, Additive Manufacturing (AM) specialists
