Stereolithography
Stereolithography (SLA) is a 3D printing technology based on the photopolymerization of a resin contained in a tank, through the action of a laser beam that emits ultraviolet radiation.
SLA was the first additive manufacturing technology to be marketed in the early 1980s. Stereolithographic 3D printing systems were designed to produce prototypes or models of high aesthetic quality. Even today, Stereolithography remains the 3D printing technology able to offer the highest level of resolution on the market.
Stereolithographic systems can process photopolymers in a VAT through their exposure to a light source. Layer after layer the printing platform is lowered inside the VAT until the realization of the assigned geometry is completed.
Prosilas, part of the Prototal Industries Group, uses SLA technology in rapid prototyping to produce 3D parts with complex geometries, with high precision and high surface quality even in a single day.
The products printed by SLA have an excellent aesthetic performance with regard to surface finishes such as painting and metallization by galvanic process.
With the stereolithography technique it is also possible to make prototypes of transparent material: you can, therefore, make lenses and car lights, master for silicone molds, test objects for wind tunnel.
Our stereolithographic systems are able to meet the requests of the most demanding customers in relation to the production of prototypes with very high surface resolution.
To learn more about the materials that can be used with SLA technologies, please refer to the SLA materials page. If you are interested in producing prototypes or functional parts with excellent mechanical characteristics, you can choose between the 3D systems for polymers and metals in the section Technologies.
SLA Materials
SLA – STEREOLITOGRAPHY
Prosilas has SLA systems that allow you to produce prototypes with extreme precision and high detail resolution.
Thanks to these stereolithography systems it is possible to create complex geometries, to evaluate design strategies and accelerate R&D processes.
TRANSPARENT RESIN
Used in stereolithography, it allows to create detailed prototypes with high surface quality.
Ideal applications: automotive lights, cover led, guiding lights, displays.
Through the surface finishes it is possible a total transparency or a transparent opaque finish or even an opal effect.
RUBBER - LIKE RESIN
It is a black, flexible material that replicates the characteristics of common rubbers for injection moulding.
ABS-LIKE RESIN
Simil-ABS resin is a multipurpose resin with a good cost-quality ratio.
It is the right material when you need a prototype as close as possible to the final object.
HIGH TEMPERATURE RESISTANT RESIN
It is the right material to produce parts with high stiffness, high surface quality and that must withstand high temperatures.
With this resin it is possible to produce prototype moulds for injection moulding (ex. through a babyplast press)
