Introduction to 3D Printing with Resin

Resin 3D printing, also known as stereolithography (SLA) or digital light processing (DLP), is a type of 3D printing technology that uses a liquid resin as the printing material.

With resin 3D printing, a digital model is sliced into thin layers, which are then projected onto the surface of a liquid resin using a light source. The light causes the resin to harden and solidify, layer by layer, until the entire object is formed.

Both SLA (Stereolithography) and DLP (Digital Light Processing) are 3D printing technologies that use photopolymer resin as the printing material. The main difference between the two lies in how the resin is cured to form the 3D object.

In SLA, a laser beam is used to selectively cure the resin layer by layer, based on the design. The cured resin hardens and adheres to the build platform, and the process repeats for each subsequent layer until the entire object is complete.

In DLP, a projector shines a UV image of each layer onto the resin, which is then cured all at once. This means that DLP printers can often print faster than SLA printers, but the surface finish may not be as smooth.

Overall, both SLA and DLP produce high-quality prints with fine details, but SLA may be better suited for complex geometries and intricate details due to its precision, while DLP may be faster and more cost-effective for larger prints.
