INITIAL SETUP

PREPARING BUILD PLATFORM

WARNING DO NOT DROP THE BUILD PLATFORM. TEMPERED GLASS PLATE MAY BREAK AND RESULT IN PERSONAL INJURY.
WARNING DO NOT REMOVE TEMPERED GLASS PLATE FROM PLASTIC HOLDER. CONTACT WITH TEMPERED GLASS PLATE EDGE MAY RESULT IN PERSONAL INJURY.
CAUTION BEFORE EVERY BUILD MAKE SURE THAT THE FLEXIBLE BUILD PLATE IS COVERED WITH DREMEL SPECIFIED BUILD TAPE. USE OF IMPROPER BUILD TAPE MAY RESULT IN EQUIPMENT DAMAGE AND POOR OBJECT BUILD QUALITY.

1. Your build plate consists of two parts: the flexible build plate, and the build plate holder. The build plate holder has a magnetic surface to attach the flexible build plate to, and it has two notches in the back and movable latches in the front to hold down the corners of the flexible build plate.

2.  The flexible build plate can be removed from the build plate holder by rotating the movable latches towards you (A), lifting the flexible build plate up by the blue handles (B), and pulling it out towards you (C), figure 3.

3. The flexible build plate comes with build tape installed. To remove it, lift it up from the tab at the front corner and slowly peel off. To install a new build tape, remove adhesive liner from build tape and place build tape over flexible build plate. For best results, apply build tape at center of flexible build plate and smooth outward to remove any air bubbles, figure 4.
   

4. The flexible build plate can be installed on top of the build plate holder by sliding it backwards at an angle so that the corners of the flexible build plate slide under the notches at the back of the build plate holder. Release the flexible build plate so it sticks on top of the magnet, and close the latches at the front to hold it in place.
   TIP: It is much easier to remove and install the flexible build plate if the build plate holder is already installed in the printer. In general, once the build plate holder is installed in the printer you do not need to remove it, you only need to remove the flexible build plate.

5. The build plate holder can be removed by pinching the clip located at the front of the build platform and lifting the build plate holder off the base, figure 7.

6. Install the build plate holder using the build platform clips.

LEVELING BUILD PLATFORM

WARNING DO NOT TOUCH THE EXTRUDER TIP DURING DREMEL 3D40 FLEX 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.
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 FLEX’s touchscreen.
   

3. The extruder and build platform will move into position to level the build platform. 3D40 FLEX 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 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 cane 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.
   

CONNECTING USB CABLE

1. Ensure 3D40 FLEX power switch is in the off position.
2. Connect the included USB cable to your 3D40 FLEX and computer, figure 6.
3. Open software.
4. Turn your Dremel 3D40 FLEX on using the power switch to sync your computer to your Dremel 3D40 FLEX.

WARNING OBSERVE ALL PROVIDED WARNINGS AND SAFETY INSTRUCTIONS WHEN USING THE DREMEL 3D40 FLEX. Failure to do so may result in fire, equipment damage, property damage or personal injury.
**   WARNING** DO NOT REACH INSIDE THE DREMEL 3D40 FLEX WHILE IT IS IN OPERATION. Contact with Dremel 3D40 FLEX moving parts during operation may result in poor build quality, equipment damage or personal injury.

NOTE: Your Dremel 3D40 FLEX will build test 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. The start of your first object may have some of this filament color until it transitions over to your filament color.
You have several options when building on your 3D40
FLEX:

1. On-Printer Storage
2. USB Flash Drive
3. Computer

BEFORE YOU BUILD

1. Ensure an adequate amount of filament is loaded (see page 18).
   TIP: You can determine whether you have enough filament to complete your object before building by comparing the length of filament needed as displayed by Dremel Digilab 3D Slicer to the length of filament on spool indicated by the length gauge.
   If 3D40 FLEX runs out of filament during a build, it will pause until more filament is added.

2.  Ensure build tape is applied, build platform is level and clear of objects.

BUILDING FROM ON-PRINTER STORAGE

CANCELING YOUR BUILD ON 3D40 FLEX
To cancel your object during preheating or building, tap Stop” on the touch screen. If you confirm “Yes” the extruder and build platform will move to their calibration positions.

REMOVING YOUR OBJECT

REMOVING YOUR OBJECT FROM THE BUILD PLATFORM

WARNING
DO NOT TOUCH THE EXTRUDER TIP DURING DREMEL 3D40 FLEX OPERATION OR UNTIL IT HAS COOLED DOWN TO AT LEAST 60°C (140°F). Contact with the extruder tip during or after operation before tip has cooled may result in personal injury.
WARNING
USE PERSONAL PROTECTIVE EQUIPMENT. The use of protective equipment such as heat resistant gloves and safety glasses will reduce personal injuries.
WARNING
DO NOT FLEX THE BUILD PLATE WITH THE OBJECT POINTING TOWARDS YOURSELF AND OTHERS. Objects flying off the build plate may result in personal injury.
WARNING
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.
WARNING
DO NOT DROP THE BUILD PLATE HOLDER. Tempered glass plate may break and result in personal injury.
WARNING
DO NOT TWIST OR BEND THE BUILD PLATE HOLDER WHILE REMOVING OBJECTS. Tempered glass plate may separate from plastic holder and result in personal injury.
WARNING
AVOID SCRATCHING THE BUILD PLATFORM WHEN REMOVING OBJECTS. SCRATCHES IN THE BUILD PLATFORM WILL RESULT IN IMPROPER OBJECT CREATION.

1. Wait for the extruder to cool before removing your object.
2. With the object still attached, remove flexible build plate from the build area. See page 20 for detailed instructions.
3. Flex the build plate with the object pointed away from yourself and others. Push on the back of it with your thumbs using your other fingers to hold onto the handles, figure 9. The part will release and will either fall off or be easy to pull off with your hand.
4. For thin or small parts, flexing the build plate may not be enough to release the part. In these cases, gently use the object removal tool to remove the object from the build plate, figure 9.

REMOVING SUPPORTS (IF REQUIRED)
Use needle nose pliers to remove supports that are inside your object or hard to reach.

BEST PRACTICES

1. ALWAYS USE BUILD TAPE.
2. Ensure your build plate is level before every object.
3. Ensure spool is installed properly and can rotate freely.
4. When using your Dremel 3D40 FLEX for the first time or after changing filament, allow Dremel 3D40 FLEX to extrude until material is consistent with the installed filament color.
5. It is important to watch your Dremel 3D40 FLEX begin building objects. Your object is most likely to experience difficulty in the beginning. Thankfully, this is also the most convenient time to cancel the object, clean the build plate, and start your object again. Remain near the Dremel 3D40 FLEX during the building process.
6. It is important to save your Dremel 3D40 FLEX packaging as it will make re-boxing and transporting your Dremel 3D40 FLEX easier.
7. Ensure that you store filament spools in an environment that is not moist or too hot. It is recommended that you do not remove the filament spool from its airtight packaging until use.
8. Use object removal tool gently to avoid damaging the build plate or object.
9. Whenever possible, it is best to locate your object in the center of the build plate. Using the best orientation for your object is critical. Ensure that your object is located on the build plate and that you are using the best orientation for building.
10. For steep overhangs (Less than 45 degree angle) it is recommended to build with support.
11. Always remove the build plate before removing the object.
12. Low speed sanding is recommended to prevent remelting of the object.
13. The Dremel Digilab 3D Slicer software will display the length of filament required for each object. Compare this to the length indicated on the spool length gauge.

MAINTENANCE

UNCLOGGING THE EXTRUDER
Use the unclogging tool to clean the extruder and unclog built up filament.

1. Wait for extruder to heat up insert the unclog tool into the extruder intake (top).
2.  Clogged debris will be pushed down and will extrude from the extruder tip.
