Stereolithography
Stereolithography is an additive manufacturing process that uses a vat of liquid UV-curable photopolymer resin and a UV laser to build parts one layer at a time.
Benefits of stereolithography include:
- Parts with smooth sidewall quality and detail
- Low-volume part production of complex geometries
- Tight tolerances, layer thickness of between 50 to 200 microns
- Versatile range of materials for specific applications
Stereolithography is commonly used as a prototyping technology within industries that need to print parts or models to validate fit form and function or for concept visualization. Stereolithography is also used in manufacturing applications for short-run part production, such as vacuum castings, injection mold tooling, investment casting master patterns, and functional end-use part production for certain environments.
Due to its competitive build times and the superior quality of the finish straight off the machine, very little post-processing is required, providing cost savings and reduced lead times.
Materials
-
Somos Momentum was developed in collaboration with footwear manufacturers to create a solution that prints tools with high accuracy, quality and fine feature detail.
-
Somos NeXt provides the accuracy of stereolithography with the look, feel, and performance of a thermoplastic. Somos NeXt is nearly indistinguishable from finished traditional thermoplastics, with the toughness, durability, and accuracy not traditionally seen in stereolithography resins.
-
Somos PerFORM is the material of choice for applications that require strong, stiff, high-temperature resistant composite parts. With its excellent high heat tolerance, outstanding detail resolution and stiffness, Somos PerFORM is the ideal material for a variety of applications.
-
Somos® PerFORM Reflect utilizes patented new technology that reduces and can even eliminate the finishing work required by traditional materials. Somos® PerFORM Reflect produces strong, stiff, temperature-resistant composite parts ideal for wind tunnel testing.
-
Somos ProtoGen 18420 is an easy-to-print, ABS-like photopolymer that produces accurate parts ideal for general-purpose applications. It offers superior chemical resistance, a wide processing latitude, and excellent tolerance to a broad range of temperatures and humidity during and after the build.
