Stereolithography (SLA)

Stereolithography (SLA) is a high-resolution 3D printing process that uses a laser to cure liquid resin into solid parts, layer by layer. Yicen Precision offers SLA services for creating highly detailed prototypes and complex geometries with smooth surface finishes and tight tolerances. SLA is ideal for visual models, master patterns for molding, and parts requiring fine features or intricate details. With a variety of resin options available, SLA printing at Yicen ensures precision, clarity, and speed for design validation and product development.

Surface Finishing for SLA

At Yicen Precision, we offer a range of surface finishing services to elevate the appearance and functionality of your SLA-printed components.

Electroplating

Deposits a thin metal layer onto SLA parts for improved appearance, strength, and EMI shielding. Suitable for display models and functional prototypes.

Assembly & Post-Processing

We provide precise assembly of multi-component prints and thorough post-processing, including support removal, detail refinement, and fit adjustments, to ensure every part meets your specifications.

Clear Coating

A transparent coating that protects SLA parts and enhances gloss or depth. Ideal for parts requiring a polished, durable, or water-resistant finish.

Epoxy Coating

Applies a clear or tinted epoxy resin to seal the surface, enhancing durability and giving parts a smooth, glass-like appearance.

UV Curing

An additional UV exposure process to fully cure SLA parts, improving mechanical strength, thermal resistance, and surface hardness.

Texturing

 Custom textures can be applied to improve grip, reduce glare, or achieve a specific visual effect. Useful for ergonomic parts or components requiring a matte or non-slip finish.

Painting & Coating

Applying primer creates a smooth, uniform base for painting. Custom paints can then be applied for color, UV protection, or enhanced aesthetics.

Sanding & Polishing

 Manual or machine sanding smooths the surface, while polishing delivers a clean, glossy finish. Ideal for presentation models, visual prototypes, and end-use parts.

Experience High-Precision Prototyping with Yicen Precision’s SLA 3D Printing Services

When your projects demand exceptional detail, smooth surface finishes, and tight tolerances, Stereolithography (SLA) 3D printing stands out as a premier solution. At Yicen Precision, our SLA printing services combine cutting-edge technology with expert craftsmanship to deliver precise, high-quality parts perfect for prototypes and functional applications.

What Is SLA 3D Printing?

SLA is an additive manufacturing process that uses a laser to cure liquid resin layer by layer into solid parts. Unlike FDM, SLA produces parts with ultra-fine resolution and smooth surfaces, making it ideal for complex geometries, intricate details, and applications where surface finish is critical.

Using a broad selection of photopolymer resins, our SLA printers can create parts that simulate various material properties,  from flexible and durable plastics to rigid, high-temperature resins.

Why Choose Yicen Precision’s SLA Services?

  • Superior Surface Quality: SLA parts require minimal post-processing, offering smooth finishes straight off the printer.
  • Fine Detail: Laser precision enables intricate features and sharp edges.
  • Material Variety: From standard resins to engineering-grade and specialty materials tailored to your application.
  • Fast Turnaround: Quick production cycles accelerate development timelines.
  • Functional Prototypes: Strong and accurate parts suitable for testing and validation.

Our team assists with resin selection and print optimization, ensuring your SLA parts meet both visual and functional requirements.

Applications for SLA Printing

SLA is widely used in dental, jewelry, medical devices, consumer products, and engineering prototypes. Its ability to reproduce fine details makes it ideal for models, master patterns, and parts requiring aesthetic quality and dimensional accuracy.

Commitment to Quality and Precision

At Yicen Precision, we maintain rigorous quality checks to verify dimensional accuracy and surface integrity. Our SLA printing workflow ensures consistent results and reliable delivery on every project.

Yicen Precision’s SLA 3D printing services provide unmatched detail, quality, and material flexibility to support your most demanding projects. Reach out today to learn how our SLA expertise can bring precision and refinement to your next prototype or production part.
