Frequently Asked Questions About Formlabs Materials:
What is the difference between SLA and SLS materials?
SLA materials, such as Tough 2000 Resin and Grey Resin V5, use liquid resin and produce parts with excellent surface finish and detail. SLS materials, such as Nylon 12 Powder, use powdered nylon and produce durable parts without support structures, making them ideal for complex geometries and production applications.
Which Formlabs material is best for tooling and fixtures?
Rigid 10K Resin is often the preferred choice for tooling, fixtures, and manufacturing aids due to its exceptional stiffness, dimensional stability, and heat resistance.
Which Formlabs material is best for functional prototypes?
Tough 2000 Resin is often the best choice for functional prototypes because it offers ABS-like mechanical properties, making it well-suited for testing parts under real-world conditions before production.
What is the most versatile Formlabs material?
If you're looking for a material that can handle a wide range of applications, Tough 2000 Resin and Nylon 12 Powder are among the most versatile options. Tough 2000 Resin is ideal for functional prototypes and design validation, while Nylon 12 Powder is suitable for both prototyping and low-volume production.
