*Print time based on clear aligner models printed with Fast Model Resin at 160µm

**Printers with smaller build platforms might take 3 builds to achieve the same throughput as Form 4BL. In these cases, we summed up the print times of these builds.

Repeatable accuracy you can count on.

Consistently Accurate

Repeatable accuracy across prints on a single printer, and across printers.

Smoothest Surfaces

Lower peel forces, light touch supports, and 46 µm pixel size with pre-tuned anti-aliasing.

Sharpest Details

Highly collimated light and 46 µm pixel size with pre-tuned anti-aliasing for subpixel resolution.

  • 95% of the surface within 50 μm of the CAD model. 99% of the surface within 100 μm of the CAD model.

The Power Behind Form 4BL

Low Force Display (LFD)™

The Power Behind Form 4BL
The Backlight Unit generates a uniform area projection of an ultra-high power light using 145 LEDs and collimating lenses. It cures resin quickly and precisely, delivering blazing fast print speeds with excellent print quality and accuracy anywhere on the build platform.

I was very happy with the print quality on the Form 4B, and it's the same on the Form 4BL. We can use Form 4BL for our products because we need to trust our dental models and the print quality is one of the best on the market. We are currently using the Form 4BL for all our model production, and the Form 4Bs for biocompatible applications. With the Form 4BL's build platform, which is around three times larger, we can now produce three times more models with a single user intervention.”
