Stereolithography (SLA) is a 3D printing technology that uses a laser to cure liquid resin into solid objects. The process begins with a digital model, which is sliced into thin layers. The laser then selectively hardens the resin layer by layer, building the object from the bottom up. This method is known for producing high-resolution and detailed prints. SLA is widely used in various industries, including aerospace, automotive, and healthcare, for prototyping and creating complex parts. Its ability to produce smooth surfaces and intricate designs makes it a popular choice for designers and engineers looking to bring their ideas to life.
