Technical Specifications

Principles of SLA Technology

Stereolithography (SLA) is an additive manufacturing process that uses a laser to cure and solidify thin layers of photopolymer resin. The process begins with a digital 3D model, which is sliced into thin layers. The SLA machine uses a laser to trace each layer’s shape in the resin, curing it to form a solid structure. This process is repeated layer by layer until the entire model is built.

Material Properties and Types Used

SLA technology primarily uses photopolymer resins, which can be engineered to exhibit various mechanical properties. These resins range from standard, tough, flexible, and castable materials, each suited for different applications. For example, tough resins are ideal for functional prototypes, while castable resins are perfect for creating molds in the jewelry and dental industries.

Resolution and Accuracy Details

One of the standout features of SLA technology is its high resolution and accuracy. SLA printers can achieve layer thicknesses as fine as 25 microns, allowing for incredibly detailed and precise models. This high resolution is crucial for industries requiring intricate designs and tight tolerances, such as medical devices and complex engineering components.

Speed and Efficiency Metrics

SLA rapid prototyping is known for its speed and efficiency. Depending on the model’s complexity and size, SLA printers can produce high-quality prototypes in hours rather than days or weeks.
