This is the state where no additional surface finishing is applied after the material is processed.  Processing marks and scratches can be easily seen on the surface.

A matte surface is created through the brushing and polishing process. This is a typical hairline finish. (Ra 0.4~0.8µm brushing, 300~600 grit polishing)

A matte surface is created using bead blasting (shot blasting). It is commonly used for deburring and matte finishing. (Ra 1~3.2µm bead blasting)

Glossy painting involves finishing with a sanding process, surfacer application, followed by painting and UV coating (or glossy finishing). Due to the thickness of the paint, a positive tolerance of more than 0.1mm may occur. Various colors can be achieved based on Pantone C color standards.

Matte painting involves finishing with a sanding process, surfacer application, followed by painting and matte finishing. Due to the thickness of the paint, a positive tolerance of more than 0.05mm may occur. Various colors can be achieved based on Pantone U color standards.

Rubber painting involves finishing with a sanding process, surfacer application, followed by painting and SF coating. It creates a soft texture with a thin rubber coating on the surface. Due to the thickness of the paint, a positive tolerance of more than 0.08mm may occur. The process is based on Pantone U color standards.

A powder coating of plastic or paint material is applied to metal parts and then heated to form a uniform coating. It is used to provide high durability and protection against corrosion and mechanical damage.

The metal parts are oxidized to a black color, simultaneously enhancing durability by preventing corrosion and wear.

After 3D printing, support marks are removed and surface sanding is performed, primarily focusing on the outer surface.

This surface finishing process smooths the rough surface of transparent 3D printing materials to achieve transparency. Even when printing with transparent materials, the surface will not be clear unless post-processing is applied due to surface layers.

This surface finishing process uses bead blasting to create a uniformly rough matte surface on transparent 3D printing materials, resulting in a translucent finish.
