Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligo...

Learn about stereolithography (SLA) 3D printers, materials, applications, and how resin 3D printers compare to other types of 3D printing technologies.

SLA (Stereolithography) is a popular 3D printing technique and one of the leading resin printing technologies. It stands out in the additive manufacturing industry due to its ability to create highly accurate, isotropic, and watertight prototypes.

1 day ago · SLA 3D printers typically operate at a printing speed of 25 mm/s. This rate can vary based on the intricacy of the part being printed and the specific settings chosen for the print job. The precise control of the UV laser allows for consistent curing times, contributing to the overall efficiency of the SLA printing process.

3 days ago · The Star of the Show: Photopolymerization. The heart of SLA printing is a process called photopolymerization.It may sound complicated, but the idea is simple: The Liquid: It starts with a special liquid called photopolymer resin.This isn’t just any liquid; it’s a mix of monomers, oligomers, and photoinitiators. The Trigger: Photoinitiators are like …

Dec 11, 2023 · SLA (Stereolithography) 3D printing is an additive manufacturing technology that employs liquid resin materials to create three-dimensional objects. This process involves the use of a high-precision laser that selectively solidifies the …

Oct 3, 2024 · Stereolithography (SLA) is a type of 3D printing process that uses ultraviolet light to cure liquid resin into solid objects. Most often, SLA printers create models upside down, featuring a build platform that descends into a vat of photopolymer resin.

Apr 11, 2025 · Stratasys Ltd (NASDAQ: SSYS), the global provider of polymer 3D printers, has launched the Neo®800+, a new stereolithography (SLA) 3D printer engineered for large-format, high-accuracy ...

Jan 29, 2025 · There are many SLA printers available on the market, but not all of them are suitable for printing large objects. 1. Formlabs Form 3L. The Form 3L is the largest 3D printer from Formlabs, a pioneer in SLA printing. It has a build volume of 13.2 x 7.9 x 11.8 inches, which allows you to print large models in one go.

Feb 7, 2025 · SLA printers utilize stereolithography to convert liquid resin into 3D objects, enhancing precision in manufacturing. They provide high-resolution prints, speed production, and generate less waste due to selective resin usage.
