Digital Light Processing - Ideal for serial production

The benefits of MSLA technology

MSLA (Masked Stereolithography Apparatus) technology is based on a photopolymerization process, using an LCD screen to solidify a resin layer by layer. Very similar to DLP and SLA, it offers excellent surface quality and high precision, ideal for prototypes or small parts requiring great finesse.

Ultra precision

Fine detail thanks to LCD resolution

Speed

Fixed layer time for any number of parts

Small series

Ideal for small and pre-production runs at industrial level

Light-curing with digital masking

MSLA (Masked Stereolithography Apparatus) technology is based on a planar exposure photopolymerization process, in which a high-resolution LCD screen selectively masks UV light to solidify photosensitive resins, layer by layer. Unlike SLA (point-by-point laser) or DLP (digital projector), MSLA simultaneously exposes an entire layer, improving dimensional regularity, reducing the risk of optical distortion, and offering high processing speed, regardless of complexity or number of parts.

Ideal for small series and prototyping.

Simultaneous exposure makes printing time independent of the printed surface, positioning MSLA as a particularly competitive solution for high-density prototyping or small series production, while maintaining high XY precision (35-50 µm).
Exposure finesse, coupled with controlled cost, makes this technology accessible while guaranteeing a high level of detail and excellent surface finish, even on fine or complex geometries.

Technical resins with a wide range of properties

Thanks to its compatibility with high-performance materials, MSLA makes it possible to go beyond simple aesthetic prototyping. The resins on offer (notably Clear Resin V5 and Tough 1500 Resin V2) can be used to produce technical parts with specific mechanical, optical or thermal properties, paving the way for demanding applications in electronics, medicine, product design or microfluidics.

Our materials available in MSLA

Clear

Clear Resin V5 is a new-generation standard resin, optimized for fast MSLA printing with excellent shape fidelity. It enables the production of translucent to transparent, rigid parts with an excellent surface finish, comparable to acrylic parts.
Used in fields such as fluidic devices, optical components, analysis housings or rapid molds, this resin also enables advanced polishing to achieve 85% light transmission at 2 mm thickness. In terms of mechanical performance, it offers a tensile strength of up to 60 MPa and a flexural strength of 105 MPa after post-polymerization at 60°C, while retaining a bending temperature of up to 59°C.

Tough

Tough 1500 Resin V2 is designed to reproduce the behavior of technical polypropylene, combining rigidity, high elongation (up to 155-210% depending on post-treatment) and impact resistance. Ideal for snap-on functional parts, resistant housings or jigs subjected to dynamic stress, it also offers excellent long-term durability. Its flexural strength reaches 41 MPa, with a bending temperature of 66°C (0.45 MPa). It lends itself particularly well to recurrent mechanical applications, with proven resistance to thermal aging and bending cycles (up to 11,000 cycles according to Ross test).
