Low Force Display™ (LFD)

The Power Behind Form 4L

Low Force Display™ (LFD)

The Power Behind Form 4L
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.

A wide range of applications to help you excel in your work.

“Having the ability to prototype our ideas quickly because we can generate more versions and test those ideas quickly with Form 4L has allowed us to bring concepts further, faster. We can integrate new features into products that would have been difficult to before.”

Rapid Prototyping

 

Brose


 

“The new Formlabs 4L allows us to print large parts fast. For example, we use Form 4L to print setup parts for our weld cell in just hours instead of overnight. This allows the Brose welding experts to program the robot prior to the metal stamping components arriving. With the new Fast Model Resin, we receive the detail required and the rigidity needed in a faster time than ever before.”

 

Matthias Schulz,
Manager, Seat Prototyping, Brose North America

Eaton


 

“When we upgraded to Form 4, it truly was like a step change in the technology. All of a sudden, this process that was really intriguing from a quality standpoint and a dimensional accuracy standpoint is now lightning fast. So now we’re combining ease of use with efficiency and accuracy and reliability.”

“Form 4L allows us to print big parts of super high-quality, barely any hand finishing on them, and readily usable. The machine has been flawless for the entire time we have had it.”

Hasbro


 

"I really appreciate the reliability paired with the speed. It's not one or the other, like many other tools. Now I can commit to internal deadlines and feel confident that I can deliver every time."

 

Robert Mackowiak,
Rapid Prototyping Engineer

 

Manufacturing Aids & End-Use Parts

 

Viking Yachts


 

“The Form 4L benefits boat manufacturers of every size. I’m making one-off custom parts that look like they were injection molded — that’s the extra Viking touch, something you can take pride in. 3D printing has game-changing potential for the industry.”

 

Winston Zeberlein,
Advanced Manufacturing Engineer, Viking Yachts

 

Manufacturing Aids & Rapid Prototyping

 

UbeCube


 

“Before we got the Form 4L, we had to prototype larger items and we needed to get those relatively quickly. Sometimes those part batches shipped to the US in a month and would be $3,000-4,000. To get those same parts manufactured at a USA printing company is even more expensive, five to six thousand. At that point, Form 4L wasn't even a long-term payout — it paid for itself in two runs of parts.”

 

Isaiah Tarwater,
Industrial Designer, UbeCube

 

End-Use Parts

 

Sirris


 

“With the Form 4L, we’re just scratching the surface of what’s possible. The ability to customize and iterate quickly gives us a significant edge in the market.”

 

Jon Howard,
Co-Founder and Operations, Sirris
 

End-Use Parts

 

Steam Factory


 

“The printed parts cost 25% less to print on Form 4L than when we were printing on the Form 3Ls. That's a combination of lower material cost and higher speeds.”

 

Rick Beddoe,
Principal Engineer/CEO, Steam Factory Design and Development

 

Rapid Prototyping

 

Microsoft


 

“We were able to do three full builds in three days instead of a week and a half. So Form 4L already paid for itself in that build alone.”

 

Mark Honschke,
Additive Prototyping Lead at Microsoft’s Advanced Prototyping Center

 

End-Use Parts

“Every interaction you have with these printers is so easy and refined. When your tools are this nice to use, it not only removes the friction of making stuff but makes it thoroughly enjoyable every time you fire them up.”
