Ever since it launched its first offering in 2014, Dremel has come a long way to be a respected brand in the world of 3D printing.

This is especially true for education-focused 3D printer settings, proving to be a useful manufacturer for schools and other educational institutions.

Following the classroom approach, the Dremel Digilab 3D40 was designed with schools and universities in mind. It has a lot to offer thanks to a state-of-the-art design and an array of upgraded features.

But the 3D40 doesn’t come cheap! In this Dremel DigiLab 3D40 Flex review, we consider its features and overall performance to determine whether it’s worth the money!


If you didn’t know anything about 3D printers, you’d be forgiven for thinking the Digilab 3D40 Flex is a microwave. Measuring 18.5 x 23 x 19.5 inches, the printer is slightly larger than its sibling, the 3D45.

It weighs 44lbs and features a close frame design with a transparent plastic door at the front.

This means you have to pull the door outward to access the print bed and the benefit of this door is that the print job is protected whenever the printer is running. 

The printer boasts a sizable build volume at 6.7 x 10 x 6 inches, which should allow you to create bigger print models. At the front of the printer is a prominent control panel that’s been mounted on a 4.5” touch screen.

The screen comes in handy when you want to load the filament, enable computer-free printing from the USB drive, or tweak other settings.

This single extruder printer offers a variety of connectivity options, allowing you to print over an Ethernet, USB, or WiFi connection.

Furthermore, it can connect through the web to Dremel’s Print Cloud when you want to slice files in preparation for printing. 

The only downside to the 3D40’s design is that it can only support PLA filament, which is a limitation to creative or artistic users hoping to print with other filament materials. 


Overall, the Dremel Digilab 3D40 Flex produces high-quality prints! The default print resolution is a satisfying 200-micron layer, although you can use the high-speed 300-micron layer. 

Comparing the different print settings, the quality of modes ranges from fair to excellent, although the lower speed setting slightly enhances the print quality.

The more notable difference between these settings is the time taken for the prints to be completed. 

I used a couple of geometry test models, with raised text and different shapes on an inclined surface, for my print test.

To cut a long story short, the shapes were well-formed with defined edges, although some surfaces were textured where they should have been smooth. 

The results were simply satisfying! Also, the removable flexible steel build plate used on the 3D40 Flex makes for easy extraction of the final print while the PLA offers great adhesion with the heated bed. 

Being a closed-frame 3D device, this printer is relatively safer to use compared to other open-frame models.

The door and lid at the front remain closed during printing, to reduce your chances of accidentally touching the hot metal extruder. 

Something else I liked about this printer is that it is very quiet.  I did not hear the printer sitting 10 feet away from it during printing.


There are various exciting features on this printer, but the most significant, which can be taken from the name (3D40 Flex), is the flexible build plate. 

This configuration makes it easy to remove the finished prints and saves you the trouble of using a spatula.

Furthermore, it aids in keeping the print bed level and maintaining the calibration since you don’t have to shake the device whenever you want to get a print off. 

At the top of the flexible bed, you find a replaceable layer that assists parts to adhere even better during printing and pull out easily after the process. 

Another feature worth mentioning is the extra print mode that the manufacturer added to offer enhanced efficiency when you want continuous output.

When you select the new “high-speed mode”, the device can print up to 30% faster, saving you valuable time.

This is something that will come in handy in a classroom setting, where time is a constraint or when you simply want to see a draft of a print before printing the final model. 

The Demel Digilab 3D40 also features a closed-frame desktop design that seeks to deliver a 3D printing configuration tailored for education.

To make the printer suitable for learning institutions, the unit comes fully assembled so that you only have to fill in the filament and level the bed to get it going.

This plug-n-play operation comes in handy in a classroom context. Furthermore, the device is UL-Safety Certified and the fully enclosed frame limits the possibility of accidents when the printer is running. 

The printer is also subjected to rigorous testing to achieve a rugged aluminum build that will stand the test of time. 

Another interesting feature is the automated 9-point leveling system integrated into the printer. This features a sensor that detects any differences in the print bed before automatically correcting it for successful printing.

Finally, the 3D40can easily connect to the cloud over Ethernet or Wifi.

On the downside, the printer only supports Dremel’s PLA filament, which is not only expensive but prevents you from experimenting with other types of filament material.


The Dremel Digilab 3D40 Flex will cost you just under $1400, which may be out of reach for some user’s budgets.

However, this unit was designed for classrooms and delivers high-quality prints. The special PLA filament it employs is a little pricier than the normal PLA.

On the bright side, the machine is ruggedly constructed to ensure that it will last long while experiencing very few issues down the line.

There is little to no maintenance needed when using the Digilab 3D40, which saves you a few crucial bucks in the long run.

If this high price tag is outside of your budget range, you can check out some decent alternatives that cost under $1000.


Dremel offers its customers unrivaled support, and this is what makes them such a popular brand. In case you run into any glitches during printing, you can easily consult the Help guides provided for possible solutions.

If nothing is working for you, try to call or message customer support and the reply will come in good time.

The manufacturer has helpful experts on hand to answer all your queries and provide guidance in resolving any issues that may be troubling you.

Finally, there is a lifetime guarantee that accompanies the printer when you buy it. You can take the machine to the manufacturer for repairs anytime it experiences a malfunction without having to worry about spending a dime!



Overall, the Dremel Digilab 3D40 Flex is an excellent 3D printer choice for the classroom setting. It features user-friendly setup and operation, fast connectivity, safe design, and produces high-quality prints.

Although the filament is limited to Dremel's PLA, it is easy to work with and proves to be sufficient for basic education. So, if you want something that gives you more flexibility as an artist, you may try out its sibling, the 3D45.

There is no better way to welcome students into the beautiful world of 3D printing than using a helpful and tailored tool like the 3D40 Flex!
