Formlabs Form 3

The Form 3 by Formlabs is a versatile and professional 3D printer, designed for producing small, accurate and detailed prints in a variety of materials.

The Form 3 uses Low Force Stereolithography (LFS); an advanced form of stereolithography (SLA) 3D printing technology that uses linear illumination and a flexible tank to turn liquid resin into flawless prints. The resulting output are consistent, highly repeatable 3D printed parts with an excellent surface finish.

With a build size of 145mm x 145mm x 185mm, the Form 3 features a re-engineered optical system, the Light Processing Unit, which maintains a precise, dense laser spot of 85 microns for accurate prints, and uses a newly designed Form 3 Resin Tank with a flexible base. The 3D printed parts have tear-away light-touch supports, for easy clean-up.

The Form 3 uses Formlabs 1 litre resin cartridges, in a range of materials*. 

Key features of the Form 3 include:

  • Light-touch supports, that are easy to tear away

  • Precise, dense laser spot size of 85 microns for accurate, detail prints

  • Integrated sensors to monitor and maintain conditions for consistent performance

  • Versatility to print in a range of resins

The Form 3 has excellent connectivity via Ethernet, Wi-Fi and USB and is compatible with Windows, Mac and Linux operating systems. The print software, PreForm allows for management of the Form 3 within teams to monitor and manage print flow.

The Form 3 is compatible with the Form Wash and Form Cure for a streamlined post-processing.
