FAQ
Resin 3D printing is one of the most popular 3D printing processes and was the world's first 3D printing technology, invented in the 1980s. It has since gained widespread adoption across hundreds of thousands of professionals in industries ranging from engineering and manufacturing to dentistry and education.
Resin 3D printers use a light source to cure liquid resin into hardened plastic through a process called photopolymerization. This produces highly accurate, isotropic, and watertight parts with fine features and smooth surface finishes.
Resin 3D printed parts offer the highest resolution and accuracy, the clearest details, and the smoothest surface finish of all plastic 3D printing technologies. The wide range of resin formulations also makes them highly versatile, matching the optical, mechanical, and thermal properties of standard, engineering, and industrial thermoplastics.
Formlabs desktop resin printers start at $2,625 for the Form 4, while large-format options like the Form 4L start at $7,125 and the Form 4BL starts at $16,249. Entry-level hobbyist resin printers can cost as little as $300, though they involve trade-offs in reliability, workflow, and material options.
Yes, Formlabs resin printers are well-suited for beginners thanks to an easy-to-use end-to-end ecosystem, extensive training resources, and personal support. They are also among the most popular 3D printing solutions found in educational settings.
Post-curing is recommended for most materials to help parts reach their highest possible strength and stability. For biocompatible materials, post-curing is required to meet the safety standards set by regulatory agencies.
Resin prints can be extremely strong depending on the material used, and they are isotropic, meaning they offer consistent strength in the X, Y, and Z directions. Resin parts are also generally waterproof and airtight, with cured resins exhibiting very low water absorption.
Yes, Formlabs offers Open Material Mode, an optional one-time lifetime license per printer that unlocks the ability to use third-party resins. Formlabs also offers certified third-party resins for added flexibility.
Resin 3D printing is generally safe, and Formlabs designs its resins to be as safe as or safer to handle than common household chemicals or adhesives. It is always recommended to consult the safety data sheet (SDS) for any new material before use.
