Application: Rapid prototyping, as well as functional and operational requirements where the appearance is not the primary consideration.

• Bead Blasting

This method works by converging pressurized inert gas or air with abrasive media, such as glass beads or aluminum oxide, onto the surface, creating a uniformly textured rough surface or a matt finish.

Roughness (Ra Value): Generally ranges between 1.6 µm and 3.2 µm (63 µin and 125 µin).

Application: Electronics, design objects, and matte finish made by Yoshiyuki.
Anodizing

Anodizing is an electrolytic process that affords corrosion resistance by increasing the thickness of the natural oxide coating on aluminum surfaces. In addition to enhanced strength, Anodizing can also enhance appearance.

• N/A: Type II anodizing is about 5 to 25 μm thick, and Type III (hard anodizing) is 25 to 150 μm.

Application: Because the practice increases the color options for application sectors other than image culture, the technique also has a great share of parts such as aerospace components, cars, and consumer goods.
