What Resources are Available for the Form 4 3D Printer?


Does the Light Processing Unit (LPU) need to be replaced frequently?

No. The LPU is a long-lasting consumable tested to deliver consistent print performance throughout its lifetime. The LPU 4 has an expected lifetime of 600k - 2.7M layers, depending on the material and layer height printed.

Why does Form 4 use 4K resolution, not 8K or 12K?

Form 4 uses a 50um 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 4 is expected to deliver the same print quality as printers with a higher resolution LCD.

How does the peel force on the Form 4 compare to the Form 3?

Formlabs developed a specialized print engine and resin tanks to minimize peel forces. This allows the Form 4 tanks to last longer, the prints run faster, and the parts look better.

Can I use my Form Wash (1st generation) with Form 4?

Yes, you can remove the parts from the Form 4/B build platform and use your existing Form Wash. However, the Form Wash (2nd Generation) is required to fit the new Form 4 build platform has a larger build area (and therefore larger
build volume). The maximum part size that can fit in the legacy Form Wash is 145mm × 145mm × 175mm.

Form Wash (2nd Generation) also has 3x more agitation and improved longevity allowing you to wash 67% more parts before
replacing your solvent.

Do Form 3 cartridges, resin tanks, and build platforms work on Form 4?

No. The cartridge, resin tank, and build platform have been redesigned to achieve significantly better performance, lifetime, and cost for the Form 4. To make those improvements, it wasn’t possible to make Form 4 printers backwards compatible with Form 3 series consumables.

Do Form 4 cartridges, resin tanks, and build platforms work on Form 3?

No. Improvements to these consumables are possible exclusively to the Form 4.

What makes the new Form 4 Resins specific to the printer?

The new print engine on Form 4 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 4?

No, it is only available for Form 3 series. printers. While 24/7 automation is not available at this time, Form 4/B is still a great option for customers with high throughput applications, offering higher throughput and lower cost per part than Form 3 and other solutions on the market.

Does the Resin Pumping System work with Form 4/B?


My tallest parts (or the number of parts per job) I printed on my Formlabs Form 4 don’t fit on the current Form Cure. What can I do?

At this time, it is recommended to use Form Cure L to cure parts printed on your Form 4 if the part or number of parts don't fit in the Form Cure.

Will the Formlabs Form 4/B be open or closed in terms of third-party materials?

Formlabs will ultimately bringing their SLA Open Platform to Form 4/B, including: Certified materials, Print Settings Editor, and Open Material License. They'lll start by adding Form 4/B to the PreForm Print Settings Editor late May 2024. Open Materials License to come.

Can I turn off or remove the camera on the Formlabs Form 4?

Yes. There are a few options for disabling the camera depending on your requirements.

  1. Disable the camera using the Touch UI.
  2. Physically cover the camera with a 3D printed part (STL file coming soon) or any other cover.
  3. Physically remove the camera from the printer. This is a 5-10 minute service loop. A simple guide is being prepared by Formlabs for any customer who wants to do this.

Can I use the printer offline?

Yes, Form 4 can be used offline. For Form 4B, you will need to connect to the internet at least once to activate the capability of printing with our biocompatible resins.

Do I need to buy a Form 4 Mixer for each Resin Tank?

For convenience, it is recommended to have 1 mixer for every different type of material you intend to print with. Otherwise, you will need to wash the Mixer in IPA using Form Wash before every material switch.

  • Ex: If you plan to print Grey v5 and Tough 2000 resins on a single Form 4 3D printer, having two resin tanks and two mixers on hand is recommended for the fastest and easiest workflow.

What is the lifetime of the Form 4 Mixer?

You can use a Form 4 Mixer indefinitely.

Is Form 4 TAA compliant?

Contact to ask about the TAA compliant version of the Formlabs Form 4.

How often should I be inspecting my resin tank?

Form 4 resin tanks should be inspected monthly.

How can I tell my resin tank is past its lifetime?

Replace a Form 4/B resin tank as soon as you notice:

  • Punctures, cuts, wrinkles, or gouges in the film
  • Wear on the film that begins to affect print quality or reliability.
    • Repeatedly printing
      the same model in the same location on a tank can cause the tank film to wear more

Do Form 4/B printers have built in tank usage monitoring?

Yes. You can check how many layers, prints, and liters have been printed on a resin tank at any time.

  • When a tank reaches >=75,000 layers and is inserted into a printer, the printer will prompt you to inspect the tank and consider replacing it.
