SLA offers a range of material options and provides parts with great accuracy to CAD and a good surface finish. The parts need to be built with support structures which are removed post process. SLA is a good option for prototypes and low volume production.
Advantages of SLA
- Great for aesthetic models
- Good surface finish/parts can be finished
- High accuracy and detail/resolution
- Wide range of materials including transparent
- Fast and inexpensive
SLA is a mature solution. As it is fast, inexpensive and accurate, stereolithography is often used for pre-production assembly prototypes as well as low volume or bespoke production parts such as hearing aids. Due to its good surface finish and ability to create fantastic aesthetic models, SLA is a solution often used for concept presentations and tradeshows. In other words, stereolithography parts are great for communication, sales and marketing models.
What is it used for?
SLA is a good choice for prototypes and low volume production where accurate parts with a smooth surface finish are required. There are a range of different materials including high temp and transparent options. SLA is used for aesthetic models and pre-production assembly prototypes as well as low volume or bespoke production parts.
