Abstract Scope |
Unlike most manufacturing processes, AM techniques such as laser powder bed fusion (LPBF) have the advantage that prototyping and volume production are based on the same process; if you can print a few widgets well, you can print 2000 with the same process parameters. Our experience at Elementum 3D is that the low barrier and low risk to experimentation with AM make quick and direct experimentation less time consuming and more intrinsically valuable than extensive modeling done in preparation for experimentation. Modeling can still be very useful in AM for narrowing the parameter space for process development. However, material behavior in LPBF is too dependent on factors like machine-to-machine variability and material feedstock quality for modeling to accurately predict reality. In this talk, I will discuss several occurrences at Elementum 3D where relying on easily obtainable experimental results rather than modeling outputs would have saved the company time and money. |
