3D Printing Surface Treatments: Common Treatment Methods

Today, with the increasingly widespread use of 3D printing technology, people are paying more attention to the surface treatment of 3D-printed parts. Surface treatment involves a series of processes and treatments of printed parts, intended to improve their appearance, mechanical properties, and service life.

Here are some common 3D printing surface treatments:

1. Sanding

Roughness adjustments were made to the printed part using sandpaper of different grits to eliminate the layered texture and uneven surfaces that may occur during the printing process.

The process involves placing the sandpaper on the surface of the print and rubbing it firmly and evenly until the desired smoothness is achieved. The choice of sandpaper depends on the printing material and the desired roughness. This removes layer marks and rough areas on the print, giving it a smooth appearance for subsequent painting or other decorative treatments.

2. Sandblasting

Sandblasting involves spraying fine-grained abrasives onto the surface of a printed model via high-pressure gas to make it smooth and uniform. This process also helps to increase adhesion, while getting rid of any texture and layered traces that may have resulted from the printing process. Furthermore, sandblasting can give the model a frosted texture, leading to enhanced aesthetics.

3. Chemical treatment

Chemical treatment refers to the use of chemical solutions or coatings to enhance the strength, smoothness, and wear resistance of prints. Additionally, it increases their corrosion and weather resistance. The most common forms of chemical treatment include pickling, gold plating, spraying, and covering, among others.

4. Spraying

Spraying refers to applying special paints or coatings to the surface of 3D-printed objects to enhance their appearance and improve wear and corrosion resistance. This process adds rich color and texture to the print while also providing an additional layer of protection, resulting in a more durable and visually appealing final product.

5. Polishing

“Polishing” refers to using abrasive tools and materials to eliminate any rough parts or particles on a printed object. This process aims to smooth the surface of the object and enhance its visual appearance and tactile sensation.

6. Details processing

The detailed treatment of 3D printing surface includes removing the support structure from the printed object, polishing the surface to eliminate layers and unevenness, filling in small defects, and applying primer and paint, among others. This treatment improves the texture and beauty of the printed product.

Summarize

These treatments can be combined as needed to achieve higher surface quality and performance requirements. Different materials and printing technologies may require different surface treatment methods, so before processing, it is necessary to understand and research the materials and printing technologies to be processed.
