What is Stereolithography and How Does It Work?
Stereolithography (SLA) is a form of 3D printing that utilizes a laser to cure liquid resin into solid objects. Developed in the 1980s, SLA is recognized for its ability to create highly detailed and complex models.
The process involves several key steps:
- Preparation: A digital model is designed using Computer-Aided Design (CAD) software, which is then sliced into thin layers.
- Building Platform Positioning: The build platform is submerged in a vat of liquid photopolymer resin.
- Laser Curing: A UV laser traces the layer pattern on the resin surface. This process cures the resin to solid form.
- Layering: Upon completion of a layer, the platform moves down, allowing fresh resin to coat the surface for the next layer. This continues until the object is fully formed.
- Post-Processing: The printed object is removed from the vat and often goes through a cleansing process to remove uncured resin and is then cured further using UV light for enhanced strength.
Due to its precision and ability to create intricate designs, stereolithography is widely used in industries such as jewelry, automotive, and healthcare.
