Description

Additive manufacturing (AM) has gained traction in orthopedics, so why isn’t it a plug-and-play technology yet? While AM has existed for years, mass implementation takes longer than most expect because AM requires a different approach to design and comprehensive knowledge of the entire process. This presentation will review ways that AM can add value and save when design and process are properly planned and executed.

AM requires important design rules. The technology adds or melts layers. Therefore, there is a limit on the angle for overhanging surfaces. Engineers must think about the build orientation. In the event that large overhanging surfaces can’t be prevented, support material (SM) is needed. This material will support the layers on top of this SM and also function as a heat sink. Residual stresses occur due to rapid heating and cooling. SM can transfer this heat to the build platform and make sure that the part doesn’t deform or crack. These design rules can differ between the SLM and EBM process. Furthermore, the full AM process must be taken into account. Parts made by AM undergo more process steps than those that are traditionally manufactured. SM has to be removed, parts have to be clamped for milling and if required, marking is needed. Designing for the right AM process and the whole process chain has a high-added value.

Consistent part quality needs to be confirmed through validation of the whole AM process. Speeding up the implementation of AM requires more than just attention to manufacturing. The whole process chain has to be taken into account. While this way of thinking takes more time up front in the commercialization process, it allows for proper AM execution and will save time and money in the end.
