What is SLA 3D Printing?
SLA (Stereolithography) 3D printing is a type of additive manufacturing technology that uses a light-sensitive liquid resin and a laser to create highly detailed and accurate 3D objects.
By using this technology, an SLA 3D printer transforms liquid resin into precise 3D objects with high accuracy and fine detail.
ProtoTi’s SLA 3D printing services deliver high-resolution, finely detailed parts with smooth surfaces, ideal for both end-use and low-volume manufacturing, as well as rapid prototyping. We offer a range of resins, including standard, tough, and transparent options, to meet your on-demand manufacturing needs.

SLA 3D Printing FAQs
1. What is SLA 3D Printing?
SLA (Stereolithography) 3D printing is a technology that uses a laser to cure and harden liquid resin layer by layer, creating highly detailed and precise 3D objects with smooth surface finishes.
2. What materials are used in SLA 3D printing?
SLA 3D printing uses photopolymer resins, available in various types such as standard resin, tough resin, flexible resin, and transparent resin, each suited for different applications.
3. How accurate is SLA 3D printing?
SLA 3D printing is known for its high accuracy, typically achieving layer heights as small as 25 microns, which allows for very fine details and smooth surfaces in the final printed objects.
4. What types of objects can be made with SLA 3D printing?
SLA 3D printing is ideal for creating prototypes, intricate models, functional parts, custom jewelry, dental models, and more. It’s suitable for both low-volume manufacturing and end-use parts.
5. How durable are SLA 3D printed parts?
The durability of SLA-printed parts depends on the type of resin used. Standard resin offers good all-around properties, while tough resin is designed for high impact resistance, and flexible resin offers elasticity.
6. What post-processing is required for SLA 3D printed parts?
After printing, SLA parts typically need to be rinsed in isopropyl alcohol to remove excess resin, followed by a post-curing process under UV light to fully harden the parts and improve their mechanical properties.
7. How long does SLA 3D printing take?
The time required for SLA 3D printing depends on the complexity, size, and layer resolution of the model. Printing can take anywhere from a few hours to over a day for more complex parts.
8. What file formats are accepted for SLA 3D printing?
Common file formats for SLA 3D printing include STL, OBJ, and STEP. These files should be prepared with the correct orientation, supports, and resolution to ensure optimal printing results.
9. Can SLA 3D printed parts be painted or finished?
Yes, SLA 3D printed parts can be sanded, primed, and painted for a smooth finish. Additional post-processing options include polishing, dyeing, and applying a clear coat for enhanced durability and appearance.
10. How does SLA 3D printing compare to other 3D printing technologies?
SLA offers superior surface quality, fine details, and higher resolution compared to FDM (Fused Deposition Modeling) and SLS (Selective Laser Sintering). However, it may be more expensive and slower, and the material options are more limited.
