3D printed sample

Smooth surface finish:
Models printed on the Form 3L resemble polished injection-molded parts and can reach high translucency, for realistic looks-like prototyping.

Consistent precision:
A system of lasers and mirrors ensures uniform print quality, for an XY resolution of 25 microns across the entire build platform.

Advanced materials:
Each Formlabs material comes with optimized print settings to guarantee industry-leading print success and reliability, as well as standout mechanical, thermal, or biocompatible properties.

Advanced Materials for Industrial-Quality Parts

Bring your parts to life with the most comprehensive library of high-performance materials on the market, developed specifically for Formlabs printers by a team of in-house materials scientists. With simplified material switching and automatic resin dispensing, the Form 3L allows you to walk away and focus on other work once your print job starts.

Total freedom with Open Platform

Enhance your printer’s versatility with certified third-party materials, customizable print settings, or the ability to experiment with any unvalidated 405 nm photopolymer resin (optional, paid license). 

Switch Icon

Switch materials in minutes.

Avoid the hassle and mess of purging materials with our swappable cartridge system, cross-compatible with other Formlabs SLA printers.

Resins icon

Automatic resin dispensing.

Our automated resin system dispenses resin as parts print. The Form 3L holds two cartridges of resin to avoid mid-print interruptions.
