3D40 Flex

Hero Body: 

Starting at $1,399

Flexible, Fast, and Consistent

Did we create an athlete or 3D Printer?

Print Removal Just Got Easier

The 3D40 FLEX makes print removal as easy as emptying an ice tray. No more scraping and prying to remove completed prints. Don’t flex your muscles, FLEX your build plate.

Need For Speed

The 3D40 FLEX is 30% faster than the previous 3D40. Less time waiting for prints to finish means more creating.  We just paved the fast lane in 3D printing.

No Days Off 

The 3D40 FLEX is the most reliable 3D printer in its class. Our 3D printers have been slammed, dropped, and dragged for thousands of hours of testing to ensure longevity and consistent prints.

Easy On The Eyes, Easy to Use

50 to 300 Micron Prints

Make high quality prints with clean, polished finishes. So smooth, you’ll forget they were 3D printed.

PLAy With Open-Source PLA

Dremel offers the highest quality PLA filament out there, but you’re welcome to use other brands.

Print From The Comforts of Your Couch

With remote printing, easily connect your 3D40 FLEX using Wi-Fi or Ethernet, and print from anywhere in the world.

Relax, You Can Breathe

Not only does it give you reliable prints, you can literally breathe around it. The 3D40 FLEX is UL Certified making it safe to be around.

The 3D40 Doesn’t Let The Praise Go To Its Head.


I bought the 3D40 for my school district and I've never used a better 3d printer for the cost. Many other printers take a
long time to set up and figure how to use but the Dremel is super easy, and worry free. You can run it in a class and you
would even interrupt anything. Highly recommend it for any Makerspace!


It’s exactly what the company says it is – an easy-to-use, safe, reliable 3D printer that’s a perfect introduction into the
world of 3D printing. It has worked seamlessly providing students a fantastic opportunity to take their ideas from concept
to prototype and final designs. We highly recommend it in a High School environment.


I will never buy any other printer! I started 3D printing using a Dremel 3D20 model and traded that in for a 3D40 model
when Dremel released that version. The people in service are tremendous, knowledgeable, fast and efficient with any of
the few repairs that I have needed.
