Qualification of Parts Printed by Metal Additive Manufacturing

Qualification of Parts Printed by Metal Additive Manufacturing

This course on qualification of parts printed by metal additive manufacturing will cover the framework for qualification of metal additive manufacturing (AM) printed part and process for AM metal part production. The training course will focus on aspects of powder material, powder bed fusion machine, operator qualification and metal parts to be produced. The focus is on powder bed fusion of metal parts using laser beam (PBF-LB/M) method.

The course will go into detail the part classification, pre-process qualification for AM machine, in-process qualification of AM parts at specimen level and post-processing qualification for AM Parts.

The more you practise and adapt design thinking in your life the more opportunities you will have to demonstrate strategic innovation.

The main objective is to provide basic understanding on aspects of powder material, powder bed fusion machine, operator qualification and metal parts to be produced. Participant will know the requirements for part classification, pre-process qualification for AM machine, in-process qualification of AM parts at specimen level and post-processing qualification for AM Parts. Their metallurgical feature, mechanical properties, defect feature, inspection and testing requirements needed for qualification of parts printed by metal additive manufacturing based on Singapore Standard, SS 666:2020.
