Stereolithography (SLA) is an advanced additive manufacturing technique where a laser selectively cures liquid photopolymer resin in successive layers, resulting in the creation of detailed, complex parts that boast fine features and impeccably smooth surface finishes.

Why choose SLA?

Stereolithography (SLA) is an additive manufacturing technology that uses a laser to selectively cure liquid photopolymer resin layer by layer to create a 3D object. SLA printing is a popular technology used for producing highly detailed, complex parts with fine features and smooth surface finishes.

How Does SLA Printing Work?

Stereolithography part
  • The 3D model of the object is first created using Computer-Aided Design (CAD) software.
  • The model is then sliced into thin, horizontal layers using specialized software.
  • A tank filled with liquid photopolymer resin is exposed to a UV laser beam that selectively cures the resin in the shape of the first layer of the object.
  • The build platform is lowered into the resin, and the laser beam creates the next layer, which adheres to the previous layer.
  • This process is repeated until the entire object is printed.
    6. Once the printing is complete, the object is removed from the resin and cleaned in a post-processing step.
  • Once the printing is complete, the object is removed from the resin and cleaned in a post-processing step.

Advantages of SLA

High accuracy and precision

SLA printing can produce highly accurate and precise parts, with tolerances as low as 0.05mm.

Smooth surface finish

The parts produced with SLA printing have a smooth surface finish and can be produced with intricate details.

Fast printing speed

SLA printing is typically faster than other 3D printing technologies, making it a good option for prototyping and small production runs.

Wide range of materials

SLA printing can use a variety of materials, including standard resins, engineering resins, and specialty resins.

High resolution

SLA printing can achieve high resolution, producing parts with details as small as 25 microns.
