How Does SLA 3D Printing Work?

How does stereolithography work ? SLA 3D printing works by first positioning the build platform in the tank of liquid photopolymer, at a distance of one layer height for the surface of the liquid. A UV laser creates the next layer by selectively curing and solidifying the photopolymer resin.

Who invented SLA printing?

What is SLA used for 3D printing?

Stereolithography (SLA) is an industrial 3D printing process used to create concept models, cosmetic prototypes, and complex parts with intricate geometries in as fast as 1 day. A wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SLA.

How does a SLA DLP 3D printer work?

DLP (Digital Light Processing) is a 3D printing technology used to rapidly produce photopolymer parts. It’s very similar to SLA with one significant difference — where SLA machines use a laser that traces a layer, a DLP machine uses a projected light source to cure the entire layer at once.

What is SLA SLS 3D printing?

Source: All3DP. SLA, or stereolithography, is a method of 3D printing that utilizes a laser and resin. Unlike digital light projection (DLP), which uses a projector screen, SLA is distinguished by the use of a single laser directed at particular points to cure the resin and solidify a pattern.

What materials can you print with SLA?

MaterialCharacteristics
Clear resin+ Transparent material – Requires post processing for a very clear finish
Castable resin+ Used for creating mold patterns + Low ash percentage after burnout
Tough or Durable resin+ ABS-like or PP-like mechanical properties – Low thermal resistance

Is SLA a plastic?

SLA is a plastic 3D printing process that uses a thermoset liquid, not a thermoplastic, which is UV-cured in layers to form final parts.

Does SLA resin absorb water?

The resins absorb moisture and the moisture changes the properties a little (especially dimensional accuracy of thin-walled parts). Think about it when you design your next part.

Which is better SLA or DLP?

Curing: Since the curing (hardening) of the resin is done from point to point, SLA 3D printing is more accurate and the quality of the print is also better in comparison to DLP 3D printing.
