Low Force Stereolithography (LFS)™

This new generation of stereolithography (SLA) 3D printing uses lasers to cure liquid resin into hardened plastic to produce high-accuracy, isotropic, and watertight prototypes and parts with a smooth surface finish.

Fused Deposition Modeling (FDM)
FDM 3D printers extrude thermoplastic filaments, a process that creates voids in the parts and lacks the ability to reproduce fine details. This process also offers lower resolution compared to SLA, resulting in visible layer lines on the surface.

25-200 microns Z resolution

30+ functional resins
A wide range of materials for prototyping from soft silicone-like to flexible, tough, durable, and rigid varieties. Specialty materials for high-temperature applications and castable patterns. A variety of dental resins, including biocompatible materials.

2-7 filaments
A limited selection of materials for prototyping, only rigid, tough, and semi-flexible varieties. 

Setup and ease of use

Plug and print
Contact-free delivery and online or in-person training for the entire team. Easy workflow empowers anyone at your company to use the system independently after less than one hour of training.

Setup and training with on-site installation recommended. The more complex workflow and the steeper learning curve means that the system requires a skilled technician in-house to operate and maintain. 


Free and easy to use
Formlabs' free print preparation software, PreForm, automatically suggests optimal orientation, supports, and layout, with the ability to manually refine as needed. Try it now. You can also use the online Dashboard to manage printers, materials, and teams.

Stratasys also offers a free print preparation software, GrabCAD Print, with a range of basic and advanced features and online job tracking.


Pro Service
Premier support service with fast response time, customized training, replacement printer, and extended warranty—all for an affordable price.

Mandatory Contract

A mandatory service contract with multiple expensive tiers and add-ons. You can’t even set up the printer without it.


Formlabs adapted the SLA technology to the desktop in 2011 and has since become the market leader, selling more than 100,000 printers as of today.

Founded by the inventor of the FDM process, Stratasys primarily offers industrial 3D printers that are limited to large companies and service bureaus due to their high price.
