Formlabs Form 3L review

The Formlabs Form 3L is a professional resin 3D printer by Formlabs, a popular 3D printer manufacturer from the US. Formlabs focuses on delivering high print quality and reliability.

The Form 3L, along with the Form 3, was announced by Formlabs CEO Max Lobovsky almost four years after its previous version, the Form 2.

This industrial-grade SLA 3D printer is suitable for prototyping and small production series. The Form 3L is user-friendly and, according to Formlabs, is plug-n-play. Its cartridge material system indeed eliminates many painful steps implied by manual material loading.

Formlabs Form 3L vs. Form 3L

The Form 3L boasts a larger build volume than the Form 3 and is equipped with two laser units instead of one. Aside from those two elements, the Form 3 and Form 3L are essentially the same resin 3D printer.

Low Force Stereolithography (LFS) technology

With the Form 3 and Form 3L, Formlabs is introducing their new LFS (Low Force Stereolithography) technology. This 3D printing method uses linear illumination and a flexible tank, dramatically improving print quality and repeatability by reducing peel forces.

LFS technology allows for easy support removal and better part surfaces. It also new printing possibilities in regards to complex materials (e.g. high viscosity resins).

Form 3D resin 3D printer main features

  • Light Processing Units (LPU): the two high-power-density 250mW lasers deliver large yet precise prints. The module moves laterally below the resin tank, contrary to the usual fixed lasers or projectors that can be found on standard resin 3D printers.
  • Constant monitoring: the Form 3L constantly monitors its printing process and is able to notify users of its progress. Its various optical sensors also provide constant automatic calibration, and can even detect if there is unwanted dust in the machine.
  • User-friendly cartridge system: users may switch materials by simply replacing the resin cartridge. There is no need for pouring the resin into the tank manually.

Formlabs also highlights that all of the Form 3L’s main components can be manually replaced by the user. This way, users can quickly replace parts in-house instead of sending the 3D printer to the manufacturer for repair.

Formlabs resins and post-processing stations

Formlabs SLA 3D printers are compatible only with proprietary materials. Over 20 different proprietary resins are available for purchase from Formlabs. These include tough resins, high temperature resistant resins, castable resins, and others.

Furthermore, users can streamline their productions thanks to the FormWash and FormCure stations (available separately). FormWash rinses prints, while FormCure cures prints.
