SLA – Stereolithography
An industrial 3D printing process for manufacturing high-precision plastic components. The process is particularly well-suited for prototypes and components that require a high level of detail and surface quality.

How does stereolithography (SLA) work?
In stereolithography, liquid resin is cured layer by layer using light. A laser (SLA) or a projection-based light system (DLP) selectively exposes the areas that are to form the part.
After each layer has cured, the build platform lowers and the next layer is exposed. This process repeats until the part is fully built. After printing, post-curing is usually performed to achieve the final material properties.
Features & Benefits
Features & Benefits of SLA / Stereolithography
Stereolithography is known for its high precision and is often used in applications where visual quality and fine details are critical.
An overview of the advantages of stereolithography:
- very high level of detail and dimensional accuracy
- smooth surfaces with no visible layered structure
- ideal for complex and intricate geometries
- good reproducibility when using the same components
- suitable for early development and design phases
Typical applications
Typical applications of stereolithography
SLA is primarily used for prototypes and applications where visual quality and accuracy are paramount.
Typical SLA applications include:
- Design and demonstration prototypes
- Presentation and demonstration models
- Geometric and fit checks
- Design and appearance samples

Did you know?
SLA is the longest-used 3D printing process. It was invented as early as 1983 by Chuck Hull (3D Systems).

SLA Compared to Other 3D Printing Methods
Compared to FDM or SLS , stereolithography offers significantly higher detail resolution and surface quality. For components subject to high stress or those intended for near-series production, however, processes such as SLS or MJF are better suited.
Top Tips for Design
Whether stereolithography is suitable for your application depends, among other things, on the level of detail, surface finish requirements, and intended use. We would be happy to advise you —tailored to your specific application and without bias toward any particular technology.
