Digital Light Processing
Benefits
- Fast build times
- High surface finish and details
Disadvantages
- Large items may need lots of support
- Models may show slight surface texture due to pixels in the screen
How it works
Our digital light processing (DLP) technology works by projecting a 2D profile of your parts, layer by layer, into a liquid photopolymer resin using a high-resolution UV screen or projector. Unlike SLA, DLP cures the entire profile of the build at once, resulting in faster print times. While support removal can sometimes leave small artifacts, our advanced equipment and expert technicians ensure that your parts are produced with the highest level of precision and accuracy possible. We also offer a wide range of materials to choose from, including both rigid prototyping and robust engineering resins, ensuring that your parts are both functional and durable.

Additional Considerations
- Support removal can sometimes leave small artifacts, which may require additional post-processing steps. However, this is a common issue with many 3D printing technologies, including SLA and FDM.
- DLP is faster than SLA since it cures the entire profile of the build at once. However, it may not be as fast as FDM or other extrusion-based technologies.
- DLP offers a high level of precision and accuracy, resulting in smooth, detailed parts. This makes it ideal for applications that require a high level of detail, such as dental or jewelry applications.
- DLP can produce parts with a variety of materials, including both rigid prototyping and robust engineering resins. However, the range of available materials may not be as extensive as with other technologies, such as FDM.
- Like SLA, DLP requires a liquid photopolymer resin that can be messy and require additional safety precautions. FDM, on the other hand, uses solid filaments that are easier to handle and store.
Overall, DLP offers a unique set of advantages and disadvantages compared to other 3D printing technologies. Depending on your specific project requirements and budget, it may be the ideal choice for your next 3D printing project.
