Assure product quality
All of the above aspects contribute to achieving the desired quality. For high-end metal parts, compliance with stringent standards and requirements must be demonstrated through QAQC testing, which is mostly carried out by specialist QAQC labs. Two points need to be considered with respect to these tests:
Tests during product development
A significant number of 3D printing projects apply an iterative approach to product development, involving step-by-step finetuning of the production process and intermediate QAQC testing to identify areas for improvement. For these kinds of projects, working closely with the QAQC lab to accelerate product development is recommended;
High level of expertise required
Very specialized destructive and non-destructive QAQC testing may be needed to qualify high-end metal parts, meaning that a high level of expertise is required from the QAQC testing lab. Specific tests include determining resistance to creep and measuring residual stresses.
