Tape Application

Do not drop the build platform. Tempered glass plate may break and result in personal injury. Do not remove tempered glass plate from plastic holder. Contacting with tempered glass plate edge may result in personal injury. Before every build make sure that the build platform is covered with Dremel specified build tape. Use of improper build tape may result in equipment damage and poor object build quality.

1. If build platform is installed, remove by pinching the clip located at the front of the build platform and lifting the build platform off the base, figure 3.

2. Remove adhesive liner from Build Tape and place Build Tape over Build Platform. For best results, apply Build Tape at center of Build Platform first and smooth outward to remove any air bubbles, figure 4.

3. Install the build platform using the build platform clips.

Print Removal

 Be aware of your body position when using hand tools to remove objects from the build platform. Sudden tool slip and improper body position during object removal from the build platform may result in personal injury. Do not drop the build platform. Tempered glass plate may break and result in personal injury. Do not twist or bend the build platform while removing objects. Tempered glass plate may separate from plastic holder and result in personal injury.

1. Wait for the extruder to cool before removing your object.

2. With the object still attached, remove build platform from the build area.

3. Peel your object from the build platform. If needed, gently use the object removal tool to remove object from build platform. If desired, remove the build tape from the build platform while separating the object from the build platform. The build tape can then be removed from the object.

Leveling Build Platform

Watch this video for a step by step walk through on how to properly level your Dremel DigiLab 3D40 or 3D40-FLX build plate.

It is important you level the build platform every time you replace the build tape or reinstall the build platform to ensure that the build platform is evenly spaced from the extruder head. Make sure to remove any air bubbles from between the build platform and the build tape. Not leveling the build platform or eliminating air bubbles may cause objects to not build properly.

1. Make sure you have placed Build Tape on Build Platform and no objects are present. Applying Build Tape after leveling may effect the consistency of your object.

2. Tap “Level” on 3D40’s touchscreen.

3. The extruder and build platform will move into position to level the build platform. 3D40 will first check level at the back center of the build platform. The two knobs under the build platform are used to raise and lower the build platform on the left and right. The extruder contains a sensor that detects if the bed is level, no additional tools are necessary.

4. The touchscreen will indicate if your build platform is too high or too low. If the build platform is too high, adjust the appropriate knob by rotating right until you hear a “beep” and the touchscreen indicates that it is ready to verify that the bed is level.

 5. If the build platform is too low, adjust the knob by rotating left until you hear a “beep” and the touchscreen indicates that it is ready to verify that the bed is level.

6. Tap “Verify” to check the bed level. If further adjustment is needed the touchscreen will indicate the direction, if the level is correct, the extruder will move to the next point and the level process can be repeated.

7. Repeat steps 4-6 for the second position, when you bed is fully level the extruder will automatically move to the calibration position and complete the leveling process.

Filament Spool Installation

Follow these steps to change or install a new filament spool in your 3D40 printer.

If changing spools from one currently installed start here. If replacing an empty spool, or loading filament into a printer with no spool skip to Step 4.



1. Start filament load/change process by tapping “Filament” button on touch screen. Extruder will move to front right corner of print area and extruder tip will begin to heat.

2. After extruder stops moving, open the 3D40 Lid for better access to extruder.

3. If existing filament is loaded, cut existing filament near extruder intake and tap the arrow button on touch screen.

4. Remove Spool door by rotating it counter clockwise. Remove existing spool if one is present.

5. Thread tip of new filament through guide tube, place spool on spool holder, replace spool door by aligning locking tabs and rotating clockwise.

6. When you place a roll of Dremel filament into the spool holder, the printer will auto-recognize the filament type and adjust the printer settings to be optimized for the filament you are using (This will bypass any print settings loaded in your sliced file).

Note: You have the option to enter advanced printer mode to manually alter print settings after you change filament. Please check all settings (if manually entered) as improper settings may cause prints to fail, property damage, or personal injury,

7. If changing existing filament, 3D40 will automatically purge existing filament.

8: When Feed Filament screen appears, tap the arrow on touch screen and thread filament coming from guide tube into extruder intake until extruder feeds through on its own.

9.  Ensure the gears inside of the extruder have properly grabbed the filament before you finish the filament change. You will feel a tug and see the filament start to feed itself into the extruder when this occurs.

10. Filament will be drawn into the extruder and begin to exit from the hot extruder tip.

NOTE: Your Dremel 3D40 was tested by building objects before leaving the factory. These test objects may have been made with a different filament color than you are using. Therefore, a small amount of filament may be remaining in the extruder.

11. When new filament appears from extruder tip, tap “done” on touch screen to complete filament load process, return to main menu, and calibrate extruder. Carefully remove excess filament without touching hot extruder tip. If necessary, carefully remove debris from extruder tip with needle nose pliers. Use extra care not to damage the extruder tip when clearing debris. Dremel 3D40 will not work properly with a damaged extruder tip and will require replacement.
