Resin 3D printers have become vastly popular for their ability to produce highly accurate, isotropic, and watertight parts in a range of advanced materials with fine features and a smooth surface finish. Resin printing is a great option for applications requiring tight tolerances and smooth surfaces, such as rapid prototyping, tooling, manufacturing aids, models, and low-volume end use parts. 

Formlabs adapted stereolithography (SLA) 3D printing technology to the desktop in 2011 and has since become the market leader for professionals, selling more than 100,000 desktop and large-format resin printers as of today.

FAQ: Resin 3D Printers

How does a resin printer work?

Resin 3D printers use a light source to cure liquid resin into hardened plastic in a process called photopolymerization. Watch the video below to see the full workflow.

Why choose 3D resin printers?

Resin 3D printed parts have the highest resolution and accuracy, the clearest details, and the smoothest surface finish of all plastic 3D printing technologies. Resin printers are also highly versatile thanks to resin formulations with a wide range of optical, mechanical, and thermal properties to match those of standard, engineering, and industrial thermoplastics.

Resin printing is a great option for highly detailed prototypes requiring tight tolerances and smooth surfaces, such as molds, patterns, and functional parts. Resin 3D printing is widely used in a range of industries from engineering and product design to manufacturing, dentistry, jewelry, model making, and education.

How much do resin 3D printers cost?

A resin printer can cost anywhere from $300 to over $250,000.

  • On the lower end, DIY and hobbyist low-cost resin printers offer an attractive entry price point, but with substantial trade-offs in terms of a labor-intensive workflow, lower reliability, and limited material options.
  • Mid-range resin 3D printers are more tailored to professionals, with the Form 3+ starting at $2,499 and the large-format resin printer Form 3L at $8,999. 
  • Traditional industrial resin printers, used predominantly by service bureaus, are available from around $100,000.

Are resin 3D printers suitable for beginners?

Yes. In fact, filament and resin 3D printers are the two most popular processes found also in educational settings. The easy to use end-to-end ecosystem, extensive training resources, and personal support makes Formlabs' solutions the easiest resin printers to get started with.

Are resin or filament 3D printers better?

This depends entirely on your applications and preferences. Read our in-depth guide that compares filament, powder, and resin 3D printers.

Do you need to cure resin prints?

It depends on the material you use, but post-curing enables parts to reach the highest possible strength and become more stable. Achieving optimal properties is especially essential when using functional or specialty resins. For biocompatible materials, post-curing is necessary to achieve the safety standards determined by regulatory agencies. Read more about post-curing resin prints or learn more about the entire workflow for post-processing and finishing resin 3D prints.

Is resin 3D printing strong?

It depends on the material you use, but resin 3D prints can be extremely strong. Resin 3D prints are also isotropic, which means that they offer the same strength in the X, Y, and Z directions.

Explore Formlabs' materials portfolio to find the best strong engineering resin for your application.

Are resin prints waterproof?

Yes, resin 3D printed parts are generally waterproof and airtight, and cured resins have extremely low water absorption. Read our white paper for detailed testing results and clear guidelines on how to affordably 3D print customized watertight enclosures.

Is resin printing safe?

Resin 3D printing in generally safe, but some low-cost resins might have strong odors requiring ventilation and may contain more hazardous chemicals. Formlabs designs its resins to be as safe as or safer to handle than common household chemicals or adhesives. Learn more about resin care for Formlabs materials and always consult the safety data sheets (SDS) for new materials.

Can I use third-party resins in a Formlabs resin printer?

Formlabs offers certified third-party resins and Open Material Mode, an optional one-time lifetime license per printer, that unlocks access any third-party resins. Learn more about Open Platform.
