6 Process after printing
For model parts manufactured by FDM 3D printing, there may be significant lamination after
printing; In addition, some model parts need to add support, which will lead to rough support parts;
And there is deformation of the parts, resulting in differences between the printed solid model and its
digital model. Therefore, the printed sample can be post-processed according to the situation, and the
appearance of the sample can be improved under the premise of ensuring the size, structure and
mechanical properties of the sample. Common post-treatment processes include support material
removal and surface treatment.
Support material Removal Surface treatment
Water-soluble support material: It can be
removed using a high-pressure water gun,
ultrasonic cleaning machine, stirring type
cleaning machine, etc
Sanding: hand sanding, sandblasting, shot
blasting, pearlescent treatment, etc
Chemical polishing: alcohol atomization
polishing, acetone fumigation polishing, etc
Repair: soil, glue, scraping atomic ash
Machining: turning, milling, drilling, etc
Parts back-end process: painting, biting,
electroplating, etc
Peeling support material: need to use hand tools
(such as: diagonal pliers, file, scissors, etc.) to
remove
