Layer lines are generally present on prints making post-processing an important step if a smooth surface is required, especially for prints that are used for display purposes.
Post-processing Includes:
-
Curing
-
Sanding
-
Painting
-
Coating
Support Removal
After 3D printing, many objects have support structures that hold them in place during printing. These supports are often unnecessary and need to be removed carefully using tools like pliers or a utility knife. Sanding or filing may also be required to smooth out any rough areas.
Sanding and Smoothing
Depending on the desired finish, sanding or smoothing may be necessary. Sandpaper or sanding tools can be used to eliminate layer lines and imperfections on the surface. Sanding creates a smoother and more polished appearance.
Polishing and Buffing
For a shiny finish, polishing and buffing can be applied. Specialized polishing compounds or buffing wheels can be used to achieve a glossy appearance.
Cleaning
Cleaning the 3D-printed object is essential to remove any residual material or debris. This can be done with water, isopropyl alcohol, or specific cleaning solutions depending on the material used.
Painting and Coloring
To add color or enhance aesthetics, painting is an option. Acrylic paints, spray paints, or airbrushing can be used to give the object its desired look. A primer may be applied before painting to improve adhesion.
Assembly
Some 3D-printed objects are composed of multiple parts that need to be assembled. This can involve using adhesives, screws, or other fastening methods to connect the parts securely.
