FAQ
Why does Form 4L use 4K resolution, not 8K or 12K?
Form 4L uses a 46um pixel size, highly collimated light, and advanced pixel smoothing to produce razor-sharp detail and smooth surfaces. The number of pixels is only one small factor for producing great parts. Based on internal testing and beta feedback, the Form 4L is expected to deliver the same print quality as printers with a higher-resolution LCD.
How does the peel force on the Form 4L compare to the Form 3L?
Formlabs developed a specialized print engine and resin tanks to minimize peel forces. This allows the Form 4L tanks to last longer, the prints run faster, and the parts look better.
Can I use my Form Wash L (1st generation) with Form 4L?
Yes, it's possible to use the 1st generation Form Wash L instead of the new second generation. However, the Form Wash L (2nd Generation) is designed to automatically accomodate to the Form 4L's larger build volume. The 1st generation requires the additional purchase and installation of the Form Wash L Universal Build Platform Adapter to accommodate the Form 4L's max build volume.
Form Wash L (2nd Generation) also has 1.5x more agitation than the first and automatically has the Form Wash L Universal Build Platform Adapter pre-installed.
Do Form 3 cartridges, resin tanks, and build platforms work on Form 4 series?
No. The cartridge, resin tank, and build platform have been redesigned to achieve significantly better performance, lifetime, and cost for the Form 4 series. To make those improvements, it wasn’t possible to make Form 4 series printers backwards compatible with Form 3 series consumables.
Do Form 4 series cartridges, resin tanks, and build platforms work on Form 3?
No. Improvements to these consumables are possible exclusively to the Form 4 series.
What makes Form 4 Resins specific to the printer?
The new print engine on Form 4 series is vastly different from Form 3, so the new formulations were designed to take advantage of the new mSLA hardware.
How does Tank lifetime vary per material – do we have the same aggressive, moderately aggressive and not aggressive categories for different materials?
Tank lifetime is now the same for all materials. The tank design has been updated and is no longer degraded by the components present in some of Formlabs' resins.
Does Form Auto work with Form 4L?
No, it is only available for Form 3 series printers.
Does the Resin Pumping System work with Form 4L/BL?
Yes! Be sure the correct resin printer compatibility is selected at checkout or simply purchase the Complete or Premium Packages which automatically come with the pumping system.
