Stereolithography (SLA)

Stereolithography (SLA) is a type of additive manufacturing technology, commonly known as 3D printing, that builds parts layer by layer using a liquid photopolymer resin that is cured (hardened) by a UV laser or light source.

How Stereolithography Works:

1. Design: A 3D model is created using CAD software and then sliced into thin horizontal layers.

2. Printing:

  • A platform sits in a tank filled with liquid resin.
  • A UV laser or projector selectively cures (hardens) resin one layer at a time, following the pattern of each slice.
  • After each layer, the platform moves slightly to allow the next layer to be cured on top of the previous one.

3. Post-Processing:

  • The print is removed and cleaned, often with isopropyl alcohol.
  • It may go through post-curing to strengthen the part further with additional UV exposure.
  • Supports (if any) are removed.

Key Features:

  • High precision and fine detail.
  • Smooth surface finish.
  • Ideal for prototypes, dental/medical models, jewellery, and Molds
  • Uses materials like standard resin, tough/durable resin, castable resin, and biocompatible resin
