¹ With Fast Model Resin and 200 µm layer height on Form 4 Series. Based on actual print time of a range of test parts covering common applications in engineering, product design, manufacturing and dentistry. With Draft Resin V2 and 200 µm layer height on Form 3 Series. Based on 75th percentile of actual print speed of reported prints from 2023.
² Average of all materials when printing at 100 µm layer height, weighted by material popularity. The print speed varies depending on the material, layer height and part geometry. The spectrum is based on the materials with the slowest median printing speed and the highest median printing speed.
With Grey Resin V5 and 100 µm layer height, post-cured for 5 minutes at room temperature. A test model with structures in different sizes, 3D-printed on three different printers.
⁴ At 50 µm layer height. Tested with a full arch dental model with dies, four models per print job, printed on three different printers and post-processed according to the recommended settings.
⁵ If you print a job that is higher than 19.0 cm on the Form 4/B, a job that is higher than 30.5 cm on the Form 4L/4BL or a job that is higher than 18.5 cm on the Form 3/B/+, you must also remove the resin tank when removing the print. PreForm displays a warning if a job exceeds this height limit.
⁶ Assuming a part printed with support structures that resembles a rectangular prism 12.5 cm deep and 1 cm high.
⁷ The XY resolution describes how precisely the printer can cure resin in the XY plane (horizontal). It corresponds to the pixel size of the Light Processing Unit 4 and Light Processing Unit 4L.
⁸ Available layer heights vary depending on the material. See our material compatibility table to check availability.
⁹ Additional languages other than English will be available with future firmware updates for the Form 4 series.
¹⁰ The exact lifetime of a resin tank depends on the printed layers, physical wear and accidental damage.
¹¹ At 100 µm layer height. The exact service life of an LPU depends on the total amount of light energy that passes through the module, which in turn depends on the number of printed layers, the material, the layer height and accidental damage. If a replacement becomes necessary, the LPU 4 or LPU 4L can be replaced easily, quickly and cost-effectively by the user.

Unrivaled reliability. Regardless of component size or throughput.
The Formlabs Form 4L workflow: simply explained in 4 steps.
Discover the Formlabs Form 4L.
The illumination unit uses 145 LEDs and collimator lenses to generate a uniform surface projection of extremely strong light. It cures the resin quickly and precisely, guaranteeing lightning-fast printing times, excellent print quality and consistent precision across the entire build platform.
The Light Processing Unit 4L (LPU 4L) precisely masks the light from the lighting unit in the shape of the cross-section. In combination, the lighting unit and the LPU 4L ensure extremely high printing speed, accuracy and print quality on the entire build platform. The LPU 4L is durable, resistant to damage and easy to replace.
There is a special film on the top of the Light Processing Unit. This micro-textured optical film has been specially developed and provides an airflow between the resin container and the Light Processing Unit. It significantly reduces the pull-off forces so that surface quality, detail, precision and reliability are not compromised even at record speeds.
In the Formlabs Form 4L MSLA 3D printer, six control systems precisely measure the temperature, resin level, printing forces and print status and keep these values constant. Together, they ensure that consistent printing results are achieved on every printer and for every job.
The liquid resin is held in the Formlabs Form 4L Resin Tank in the printer and forms a carrier system on which the liquid resin cures. A two-layer, flexible foil film is used for this. It significantly reduces peel forces, allowing you to print at extremely high speeds without compromising surface finish, fine features, accuracy or reliability.
The Formlabs Form 4L has an integrated system for fast, precise and low-waste resin dispensing, making material changes easy. You don’t have to worry about your printer running out of resin and can change material in <1 minute. The Form 4L is still one of the only SLA printers on the market to offer this feature.
