What are the trends and key challenges in 3D post-printing?

PostProcess Technologies has just published its first annual study on post-processing trends in 3D printing. Produced in collaboration with the Society of Manufacturing Engineers, it highlights the practices and challenges that users face today, regardless of their industry. 66% of participants said they face at least two barriers with their current solutions, including time, quality and resource requirements.

In the 3D printing process, post-processing steps can often be crucial, giving the created part its final surface finish, color or strength. In recent months, there have been initiatives aimed at automating this process as much as possible, seeking to minimize its time and optimize its efficiency. Some players have even designed machines with integrated post-processing such as Velox or DyeMansion to save the user time. Moreover, PostProcess’ study reveals that for 75% of participants, the duration of the process is the main barrier to post-processing. The consensus is that overall, it is too time-consuming.

This statement is reinforced when several 3D printing technologies are used. 50% of respondents use 2 to 3 different methods, 33% more than 4, but the more technologies involved, the more post-processing challenges are numerous. This makes perfect sense given that each technology uses different post-processing techniques. For example, when talking about Laser Powder Bed Fusion, printing supports are highly recommended, so they should be removed. However, with SLS technology, they are not necessary. The report shows that the removal of printing media is the most time-consuming post-processing step for 50% of participants.
