Frequently Asked Questions

How Do I Register my Dremel 3D Printer?

You can register your Dremel 3D printer by following the instructions on our registration page.

Can I Print Objects for Storing Food?

We do not recommend you to print any object that will come in either direct or indirect contact with food.

What Happens if the Power Turns Off and On For Some Reason?

Dremel's 3D printers will turn back on to an idle state after a power disruption. The previous print project will be cancelled automatically. If the print head is still hot, the fans will turn on to cool it down.

Why Does My Printer Make a Grinding Sound When Trying to Home?

If your printer does not home smoothly, the wire bundle may be getting pinched between the gantry and the build platform resulting in y-axis belt slippage. Try repositioning the wire bundle to prevent it from getting pinched and homing should go smoothly.

How Do I Clean the Outside of my Dremel 3D Printer?

Clean the Dremel 3D Printer's exterior with a lint free cloth. Clear the outer surfaces of any debris that is visible. To avoid damaging your Dremel 3D printer do not use water, chemicals or other cleaners on the printer. Always check to ensure the extruder nozzle is clear of debris using common needle nose pliers. Also be sure to change the build tape at regular intervals.

Why Does it look like there is Dirt or Pellets In My Filament Packaging?

This is because the desiccant pack that comes with the filament developed a tear. This is common, and the "dirt" you see within the packaging is a form of salt that keeps the filament dry during storage. After the filament is opened, this can be safely thrown away in the garbage. Even though this contains salt, please refrain from eating it.

Why isn't my Filament Unloading Properly?

Please ensure that you are running the "unload" function, and that the extruder has heated to the appropriate temperature. If the filament is still difficult to remove, push down on the side mounted level to disengage the extruder's motor. Then gently pull the filament out of the extruder. Also, make sure that the nozzle is not clogged and that the extrusion head is properly heated. For further troubleshooting, please contact Dremel's customer service department for service information or visit the Support page on

Why is the Filament Blobbing on the Build Platform?

This may be the result of a build failure or a poorly constructed file. The building process may have been interrupted by the computer disconnecting, or by removing the SD card/USB flash drive during the building process. Run the Dremel Test Print to verify that your printer is working correctly, allowing the print to finish completely before disconnecting it.

Why is the Extruder Not Moving to Home Position?

Please ensure the extruder wire tube (tube with black mesh housing) moves freely and is located away from the build platform and guide rails. If caught on the build platform, the extruder will not return to home position and a loud noise may occur. In the event that extruder wire tube is caught on the build platform, power off the unit and reposition the wire tube above the build platform to allow it to travel freely.

Why won't my Extruder Head Move?

It is possible that the motors are not running correctly or that the model file is corrupted. If you are using an SD card or USB flash drive, attempt the official Dremel Test Print through your computer software. If you are using the computer software, attempt to load the test print via SD card or USB flash drive. If you are still unable to move the extruder, check your printer for firmware updates by running the updater in the Dremel 3D software. If the steps above do not resolve the issue, please contact Dremel's customer service department for service information or visit the Support page on

How Do I Unclog my Extruder?

You can unclog your extruder by using the unclog tool and following the steps in the instruction manual.

Why isn't my Filament Loading Properly?

Make sure that the nozzle is not clogged and that the filament is properly inserted into the extrusion head. The most common reason for filament not loading correctly is a bad filament tip. Ensure the end of the filament has a clean break and does not contain any kinks or strings. It is recommended that you cut a small amount of filament off the tip to ensure a clean tip. Please also ensure that you are running the "load" function, and that the extruder has heated to the appropriate temperature. For further troubleshooting, please contact Dremel's customer service department for service information or visit the Support page on

Why is the Extruder Tip Scraping the Build Plate?

The extruder tip is scrapping the build platform because the build platform is not level and the extruder is too close. If this happens you should stop building and see instructions on leveling the build platform.

Why Does My Extruder Look Like it is Off-Track?

The extruder may have skipped off the track as a result of the build platform not being level or due to a buildup of excess filament around the extruder tip. The Dremel 3D printer did not detect this skip and is one step ahead of the extruder. If this happens you should stop building and see instructions on cleaning the extruder tip and leveling the build platform.

Why Isn't My Dremel 3D Printer Starting an Object?

Please refer to the user manual and quick start guide for setup and building operations to ensure that your 3D Printer is connected and setup correctly. Also, it is recommended that you check to make sure your 3D Printer is using the most up-to-date software. For further troubleshooting, please contact Dremel's customer service department for service information or visit the Support page on

Can I Print From Popular CAD File Repositories?

Yes, you can, majority of modeling software can export files to STL, which is the file type accepted by all Dremel-compatible Software.

Can I Use Other 3D Printer Software with my Dremel 3D Printer?

You can use any CAD program to create the .stl of .obj file. However, you will need to use one of Dremel's compatible slicing softwares to convert these model files to buildable files.

How Do I Convert 3D Model Files to Dremel Model Code?

3D models should be saved in STL or OBJ format in the CAD program used to create these files. You can then use your choice of Dremel 3D softwares to convert the files into buildable models.

Where Do I Go To Service My Dremel 3D Printer?

Please contact Dremel's customer service department for service information or visit the Support page on

Do Dremel 3D Printers have Dual Extruders?

No, both of Dremel's 3D Printers are constructed with single extruder systems. This provides maximum reliability.

What is Included with my 3D Printer?

Please refer to the Products page to see the different versions and what is included.

What is 3D Printing?

3D printing is a method of creating objects through additive means. Many different forms of 3D printing exist today, but the Dremel 3D printers utilize Fused Filament Fabrication (FFF) to extrude layers of material on top of one another until an object is realized.

How Should I Store My Filament?

Storing your filament correctly extends the usefulness of the filament. Filament should always be stored in a cool, dry environment unexposed to changes in temperature or humidity. Always keep your filament inside the shrink-wrap plastic until you are ready to use it.

How Long Does Filament Last?

How long your filament lasts will depend on how often the 3D printer is used, and the quality/density at which objects are made. The lower the quality/density, the less filament required to build each object and the longer each roll of filament will last. Each Dremel filament roll will print continuously for roughly 24 hours.

Why Should I Use Dremel Filament?

Dremel filament is manufactured to provide the highest quality during operation and will help your Dremel 3D printer run smoothly. Using other manufacturers' filaments will void your warranty and may damage your Dremel 3D printer.

Why Does My Printer Print an Outline Before Printing the Object?

This pre-print activity allows the extruder to flush out any old filament that may not stick properly during your print. By purging this material, you are printing with filament at the optimal print temperatures, providing maximum hold with the first layer of the print.

What is the Difference Between the Black and Blue Build Tapes?

Both build tapes will provide the same quality of build, the main difference between the build tapes is the durability and slight differences in object removal.

How Long Will the Build Tape Last?

The black build tape will last up to 50 prints; the blue build tape will last up to 10 prints.

Will There Be Any Marks on My Print After I Remove Support Material?

Supports are designed to be easy to remove and they should leave minimal marks on your print, however if you find some marks you can sand them with fine sanding paper.

Why Are My Objects Collapsing On Themselves?

You may have forgotten to enable supports in your slicing process. Please refer to tutorial guides for the respective slicing software you are using to ensure you have enabled supports.

Can I Use More Than One Filament Color On One Object?

Yes. You can pause an object to change filament using the touch screen. Please refer to the instruction manual for more information.

Why Won't My Objects Stick to the Build Platform?

There are many reasons why objects may not stick to the build platform. You should first ensure that you have clean, debris free build tape and that it is not torn or ripped. Next, check that the build platform is level. These are the two most common causes for builds not sticking.

Why are my objects getting stuck to the build platform?

Objects sticking to the build platform is a good thing as they require a firm adhesion to the build platform to avoid slipping. This is to ensure that the object remains stable throughout building. See instruction manual for object removal instructions.

How Thick Are the Layers?

The Dremel 3D40 & 3D20 have a maximum resolution of 100 microns and a minimum resolution of 300 microns (0.10-0.30mm per layer). The higher the resolution, the smaller each layer and the better your object will look.

How Long Does it Take to Build an Object?

The time it takes to build a 3D object depends on the size and complexity of the model file. It also depends on the density you wish to build the object.

How Large is the Build Volume?

3D40: Maximum build volume is 10” x 6” x 6.7” (254mm x 154mm x 170mm). 3D20: Maximum build volume is 9” x 5.9” x 5.5” (230mm x 150mm x 140mm).

How Good is the Build Quality?

Build quality depends on a number of factors such as layer thickness and build environment. The Dremel printers (3D20 & 3D40) extrude filament into layers as thick as a sheet of paper or 100 microns (0.10mm) thick. The printers also have an active cooling fan which helps to evenly cool filament and reduce warping. They are designed to provide a fully enclosed build environment and gripped feet for stability. Lastly, an important factor is the quality of the filament used. Always use Dremel filament with Dremel's printers for the best quality.
