Pros & Cons of SLA 3D Printing
SLA 3D printing offers exceptional surface quality and high precision, making it ideal for visual models, prototypes, and parts with fine detail.
However, it’s not without trade-offs—materials can be more brittle compared to other processes, and post-processing is often needed for full functionality. Understanding these pros and cons helps you decide if SLA is the right fit for your project.
Advantages
Considerations
- Smooth surface finish
