For example, chemical smoothing with acetone is effective for ABS printed parts, resulting in surface roughness reductions of up to 90% according to research conducted by Tavakoli et al. (2019).
3. Support Removal:
Support removal ensures that all residual support structures are eliminated from the printed gears. This process prevents interference in gear meshing and optimizes the gear’s performance. According to a case study by Techmer PM, improper removal of supports led to failures in printed parts, reinforcing the importance of meticulous support removal for maintaining gear reliability.
4. Post-Curing:
Post-curing is especially important for gears made from resin materials, where ultraviolet (UV) light exposure can improve the material’s properties. During post-curing, gears are exposed to UV light to enhance their hardness, chemical resistance, and overall strength. Research from Stratasys (2019) indicated that UV-processed gears showed a 25% improvement in strength compared to those that were not cured.
5. Infiltration:
Infiltration involves saturating the surface of a printed gear with a substance, such as an epoxy resin or glue. This process fills in gaps and voids caused by the printing process, resulting in a denser and more durable gear. A report by Adan et al. (2020) found that infiltrated printed gears displayed an increase in flexural strength by approximately 40%.
6. Coating:
Applying a protective coating to the surface of 3D printed gears adds an additional layer against wear and environmental factors. Coatings, like polyurethane or ceramic, can enhance the gear’s resistance to abrasion and corrosion. A study published in the Journal of Materials Science in 2020 indicated that gears treated with ceramic coatings extended their operational life by 50% in harsh environments.
These post-processing techniques significantly enhance the reliability and performance characteristics of 3D printed gears, reflecting a combination of material science and engineering principles.
