A resin-based 3D printer in action, using UV light to cure liquid resin into solid parts. The build plate is lifting multiple translucent objects from the resin vat, with blue illumination highlighting the curing process. The printer's enclosure has a yellow-tinted protective cover to shield against UV exposure.

What is MSLA and Why Choose It?

Masked Stereolithography (MSLA) is an advanced 3D printing technology that uses ultraviolet (UV) light to cure liquid photopolymer resin into solid parts, layer by layer. Known for its precision and smooth finishes, MSLA is ideal for producing highly detailed prototypes and functional components with professional-grade surface quality.

Why choose MSLA?

  • High Accuracy: Exceptional detail and tight tolerances for intricate designs.
  • Smooth Finishes: Polished surfaces that rival injection-molded parts.
  • Fast Turnaround: Speeds up design iterations and product development.
  • Higher Throughput: MSLA’s ability to cure entire layers at once allows for faster production compared to traditional SLA, making it ideal for larger batches or time-sensitive projects.

Materials Available for MSLA

Wellan offers a variety of MSLA materials tailored to your project’s needs:

  • General Purpose Resins: Great for visual prototypes and concept models.
  • Engineering Resins: Enhanced strength, durability, and heat resistance for functional testing.
  • High-Performance Resins: Superior mechanical and chemical properties for demanding applications.
  • Specialty Resins: Options like clear or flexible resins for unique uses.
