Formlabs Launches Form 3+ and Form 3B+ 3D printers

New Formlabs 3D printers

Formlabs has announced the Form 3+ and Form 3B+ 3D printers, upgraded versions of the hugely popular Form 3 and Form 3B.

The new 3D printers print 20% – 40% faster than before, enabling same-day production for agile prototyping and production.

The speed improvements are based on both hardware and software improvements, including a more precise laser and smoother motion for the light processing unit, creating a more efficient path for the laser system.

Rapid, High-Quality Production

With the Form 3, Formlabs introduced Low Force Stereolithography (LFS), a refined, proprietary version of stereolithography.

Speed increase

With LFS, a laser moves beneath the resin tank and delivers a laser path that is always perpendicular to the print plane. The linear movement creates a consistent laser spot, which greatly increases part accuracy and repeatability.

The laser is even more precise with the Form 3+ and Form 3B+, with refined movement parameters and smoother transitions. The result is a print process that increases quality and consistency across 3D printed parts.

Crucially, these performance improvements also translate to speed. You can now print 20% – 40% faster than previously possible without sacrificing capability or quality, which unlocks a new paradigm for manufacturing.

More than an iterative update 

The Form 3+ and 3B+ are designed to help you go from design to print faster and speed up processing time, reducing your time to final part.

Form 3+ and 3B+ have improved LPU stabilisation, temperature control, and early layer performance over Form 3 and Form 3B.

The temperature control upgrades are significant, with a new heating system with improved sensors that more quickly and accurately heat the print bed.

Another improvement comes from the new Build Platform 2, a new build platform that instantly releases parts from the build platform with Quick Release, saving valuable post-processing time and eliminating the risk of damaging your part. 

Fans of the light touch support system, a unique feature to Formlabs and LFS, will also be happy to know the Form 3+ and Form 3B+ offer improvements here, with an enhanced light touch support removal experience thanks to redesigned support tips.

Two more features are worth mentioning. The Form 3+ and 3B+ have a pre-heat mode that makes them ready to print after uploading and a sleep mode that places the printers into a low energy state with near-instantaneous wake-up.
