When to choose MSLA
- Aesthetic mock-ups and product presentations
- Components with fine details and precise fillets
- Technical moulds and masters for silicone
- Smooth-surfaced parts without heavy post-processing
MSLA
Masked Stereolithography
MSLA technology enables the production of ultra-high-resolution components, ideal for fine details, smooth surfaces and complex geometries. Perfect for cosmetic prototypes, engineering models and professional applications.
File preparation
From light
to perfect form.
Every part comes to life from a CAD model, carefully oriented and supported to optimise surface quality and dimensional accuracy. The MSLA process delivers extremely fine detail and optical-quality surfaces.
Process
Optical precision,
down to the micron.
Every layer is cured with optical precision, ensuring smooth surfaces and sharp details.
The MSLA process delivers superior cosmetic and functional quality for every application.
Perfect details,
right down to transparency.

MSLA 3D printing: detail, smooth surfaces and precision
MSLA (Masked Stereolithography) cures resins with high-resolution UV light. You get smooth surfaces, fine detail and tight tolerances — ideal for aesthetic prototypes, precision components and engineering models.
Doppialinea selects engineering resins according to the stiffness, temperature and flexibility your project requires.

Limitations to consider
- Less suited to extreme mechanical loads than SLS
- UV exposure and temperature: assess the operating environment
- Very large geometries: FDM or SLS is often a better fit
Files and checks
- STL with a closed mesh and consistent orientation
- Minimum wall thicknesses for resin (see the guidelines on this page)
- Team support for special resins or tight tolerances
