Summary
Fused Deposition Modeling (FDM) 3D printing creates layer grooves. A new 3D-Chemical Melting Finishing (3D-CMF) method effectively removes these grooves, improving surface quality and mechanical properties of 3D printed parts.
Area of Science:
- Additive Manufacturing
- Materials Science
- Surface Engineering
Background:
- Fused Deposition Modeling (FDM) is a cost-effective 3D printing technology suitable for home use.
- FDM 3D printed objects often exhibit surface layer grooves, impacting aesthetics and performance.
- Existing post-processing methods may be costly or ineffective for FDM parts.
Purpose of the Study:
- To develop and evaluate a novel post-processing technique for FDM 3D printed structures.
- To address the issue of layer grooves inherent in FDM 3D printing.
- To enhance the surface quality and mechanical integrity of 3D printed components.
Main Methods:
- Development of a 3D-Chemical Melting Finishing (3D-CMF) technique using a pen-style device.
- Application of a chemical solvent to selectively dissolve and fill layer grooves on FDM prints.
- Controlled manipulation of the device to achieve surface smoothing.
Main Results:
- Demonstrated superiority of 3D-CMF over conventional post-processing methods.
- Confirmed improvements in surface roughness precision and mechanical characteristics.
- Evaluated and confirmed the safety, selectivity, and stability of the 3D-CMF process.
Conclusions:
- 3D-Chemical Melting Finishing (3D-CMF) is an effective method for removing layer grooves in FDM 3D printed parts.
- The developed technique significantly enhances surface quality and mechanical properties.
- 3D-CMF offers a promising solution for improving the utility of home-based FDM 3D printing.
