3D Printing Post Processing
Post-processing enhances 3D prints with six precise surface finishes: smooth, glossy, matte, textured, polished, and anodized. These finishes improve both the appearance and durability of parts, making them ideal for functional or visible components. For internal or rough prototypes, post-processing may be unnecessary where aesthetics are not a priority.

Perfect for functional prototypes or internal parts where aesthetics are not crucial.

Improves appearance and longevity with a range of color choices and protective finishes.

Minimizes roughness, creating a smoother and more aesthetically pleasing surface for visible parts.

Creates a protective oxide layer on metal parts, offering corrosion resistance and the option for vibrant colors and surface durability.

Applies a metal coating to enhance strength, wear resistance, and conductivity, perfect for functional and high-durability parts.

Adds a custom pattern or texture to the surface, providing grip or a unique aesthetic, ideal for tactile components.

What’s 3D Printing?
3D printing, or additive manufacturing, is an innovative technology that builds three-dimensional objects from digital files. The process adds material layer by layer until the final shape is achieved. Unlike traditional manufacturing, which often cuts away material from a larger block, 3D printing enables the creation of complex geometries and fine details with minimal waste. It’s widely used across industries, including prototyping, product development, medical implants, and aerospace. With its advantages in customization, speed, and cost-effectiveness, 3D printing is a key tool in modern manufacturing.
