Yes, some resin printers, specifically those using Stereolithography (SLA) technology, use lasers to cure liquid resin.
Here's a more detailed explanation:
Resin 3D printing encompasses various technologies, but SLA is the most well-known and one of the first types developed. In SLA printers:
- A tank holds liquid resin.
- A build platform is submerged in the resin.
- A laser beam precisely traces patterns on the resin surface.
- The laser light causes the resin to harden and solidify where it hits.
- The build platform then moves slightly, allowing another layer to be cured.
- This process repeats until the entire object is formed.
While SLA printers use lasers, other types of resin printers, such as Digital Light Processing (DLP) printers, use projectors instead of lasers to cure the resin. Therefore, not all resin printers utilize lasers, but the technology is central to SLA.
