Post-processing is one of the most crucial stages in producing high-quality and useful parts in additive manufacturing. It is commonly understood that the time and cost to perform post-processing is high. It is even higher in some cases than the actual time and cost of printing the part itself. This is primarily because of the reliance on conventional finishing methods and the lack of automation in this space. It is also due to the special features that distinguish AM from conventional manufacturing. This report includes:
- State-of-the-art post-processing solutions
- Leading post-processing system manufacturers
- Post-processing techniques available applicable to metals and polymers, including;
- Material removal
- Part finishing
- Thermal treatments
The report was created by a team of experts at Wohlers Associates—the same group that produced Wohlers Report 2022, the undisputed, industry-leading report on AM for 27 years.
