Stereolithography (SLA) 3D printing is the most common resin 3D printing process, becoming very popular due to its ability to produce high-precision, isotropic and waterproof prototypes and end-use parts in a range of advanced materials with fine features and smooth surface. finishing.

Stereolithography was the world's first 3D printing technology, invented in the 1980s, and remains one of the most popular technologies among professionals. Stereolithography belongs to a family of additive manufacturing technologies known as vat photopolymerization, commonly referred to as resin 3D printing. It uses UV laser to cure liquid resin into cured plastic.

SLA 3D printing offers the highest resolution and precision, clearest details and smoothest surface finish of all plastic 3D printing technologies, but the main advantage of SLA is its versatility. Materials manufacturers have created innovative SLA photopolymer resin formulations with a wide range of optical, mechanical and thermal properties to match those of standard, engineering and industrial thermoplastics.

SLA 3D printers use light-reactive thermoset materials called resin. When SLA resins are exposed to certain wavelengths of light, short molecular chains join together, polymerizing monomers and oligomers into solidified rigid or flexible geometries.

The resin is either poured into a tank by a user or dispensed automatically from a cartridge, depending on the concrete stereolithography machine.

SLA 3D printing begins by lowering a build platform into the resin and leaving only a thin layer of liquid between the platform and the bottom of the tank. Then, galvanometers direct the UV laser to the bottom of the resin tank, drawing a cross-section of the 3D model and selectively curing the material. Once the layer is complete, the part is peeled off the bottom of the resin tank, allowing fresh resin to flow underneath, and the platform is lowered again.

High-resolution desktop stereolithography 3D printing is an affordable option for your workspace. Whether for an engineer, product designer, sculptor, jeweler or dentist, with the right hardware, there is an SLA application for your profession. SLA 3D printing applications include a variety of fields, such as engineering and product design, manufacturing, dental, healthcare, education, entertainment, jewelry, or audiology.
