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 3D20 Build Platform

Watch this video for a step-by-step procedure on how to level the build platform (bed) of the Dremel 3D20 Idea Builder.

Do not touch the extruder tip during Dremel 3D20 operation or until it has cooled down to 60°C (140°F). Contact with the extruder tip during or after operation before tip has cooled may result in personal injury. CAUTION: 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.

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 over the build platform. Applying build tape to the build platform after leveling may effect the consistency of your object.

2. Tap “Tools” on your Dremel 3D20’s touch screen and tap “Level”.

3. The extruder and build platform will move into position to level the build platform. You will first level the front left section of the build platform. The three knobs under build platform are used to raise or lower the build platform on the left, right, and rear of the build platform.

4. Place the leveling tool between the extruder and build platform. If the leveling tool cannot slide between the extruder and build platform, adjust the appropriate knob (turning counterclockwise) until you can slide the leveling tool between the extruder and build platform with some resistance. If the leveling tool can slide between the extruder and build platform too easily, adjust the appropriate knob (turning clockwise) until you can slide the leveling tool between the extruder and build platform with some resistance.

TIP: Standard printer paper can also be used to level the build platform in the same manner as the leveling tool.

5. Tap “Next” to move the build platform toward the right knob and repeat step 4 above.

6. Tap “Next” to move the build platform toward the rear knob and repeat step 4 above.

7. Tap “Finish” to complete the leveling process. 8. Repeat steps 1 through 6 above to ensure that build platform is completely level.
