Many industrial 3D printing techniques leave behind support material that needs to be removed during post-processing. BuBclean has developed a Cleaning Challenge Device as a benchmark for evaluating the cleaning procedure for 3D printed objects.
The Cleaning Challenge Device consists of a cylindrical base station with four holes, and four separate inserts. The inserts have a circular or square cross-section of varying diameter, which have been chosen to be both realistic and challenging for typical cleaning procedures. The distance that the inserts can be placed inside the holes is a measure of the cleaning efficacy, since any remaining dirt will prevent the inserts from sliding in completely.
