Industrial SLA
3D Printing
"Stereolithography (SLA) uses a precision ultraviolet laser to cure liquid photopolymer resin layer by layer, offering high resolution and exceptionally smooth surface finish."
Stereolithography (SLA) is a 3D printing technology that uses a laser to cure a photopolymer resin, one layer at a time. The laser traces the cross-section of the object to be printed onto the surface of the resin, and the resin is cured wherever the laser hits. Once the entire object has been printed, the build platform is lowered and a new layer of resin is applied. The process repeats until the object is complete.
SLA 3D printing is a precise technology that can produce objects with high resolution and smooth surface finish. It is also a good choice for creating objects with complex geometries, such as dental implants and medical devices which require high detailing and finish. It offers higher resolution and smoother surface finish for master patterns and visual prototypes.
Industrial SLS, MJF, DLP & FDM 3D Printing
Explore our full lineup of industrial additive manufacturing processes tailored for functional prototyping, rapid tooling, and production parts.
SLS (Selective Laser
Sintering)
"Ideal for complex geometries like lattice structures and internal channels without support structures."
Selective laser sintering (SLS) is an additive manufacturing technology that uses a laser to sinter (fuse) powdered material, one layer at a time, to create a solid object. The powder is spread out in a thin layer on the build platform, and the laser selectively melts the powder particles.
MJF (Multi Jet
Fusion)
"Produces highly dense, isotropic functional parts with excellent mechanical strength and surface quality."
Multi Jet Fusion (MJF) is a 3D printing technology that uses a print head to selectively heat and fuse powder particles together layer by layer. The print head moves across the build platform, depositing a thin layer of powder and applying fusing agents.
DLP (Digital Light
Processing)
"Delivers ultra-fast layer exposure speeds and fine feature details for dental and micro components."
Digital light processing (DLP) 3D printing is a type of 3D printing that uses a digital projector to cure a photopolymer resin layer by layer. The projector shines a light through a mask onto the resin, curing it instantly where light hits.
FDM (Fused Deposition
Modeling)
"Versatile and affordable technology ideal for rapid functional prototypes, jigs, and fixtures."
Fused deposition modeling (FDM) is an additive manufacturing technology that uses a heated nozzle to extrude melted thermoplastic filament onto a build platform. The layers of material are then fused together to create a solid object.

SLA printed parts are best suited for fit, form, and assembly validation rather than demanding functional testing. Their exceptional dimensional accuracy and smooth surface finish make them ideal for evaluating product design, verifying component fit, checking clearances, and assessing overall aesthetics before production.
While SLA parts accurately replicate the geometry of the final product, standard resins are rigid and brittle, making them unsuitable for applications involving significant mechanical loads, repeated impact, or continuous stress.
