At Yicen Precision, we provide a range of surface finishing options to enhance the functionality, durability, and appearance of your Direct Metal Laser Sintering (DMLS) parts. Whether you need the raw, as-printed finish or a polished cosmetic appearance, we ensure each part meets the highest standards of quality and performance.
The default finish directly from the DMLS process, ideal for functional parts with a slightly rough surface texture. This finish provides the strongest part integrity without additional treatments.
This process creates a smooth, matte finish using abrasive media, perfect for applications that require an improved aesthetic with uniform surface texture. It enhances the part’s surface while retaining strength.
For parts that require extra precision, our machining process can further refine surface details, providing a high degree of smoothness and dimensional accuracy for tight tolerance applications.
Achieve a glossy, mirror-like finish suitable for decorative or high-visibility parts. Polishing removes any surface imperfections, providing a smooth, aesthetically pleasing result ideal for consumer-facing applications.
At Yicen Precision, we ensure that each part meets the highest standards of quality through rigorous inspection and testing.
