Safety Instructions
Building the printer requires physical dexterity, common sense, and a thorough understanding of the process. Detailed instructions are provided to help you assemble it easily. Please download them at geeetech.com.
Geeetech cannot be held responsible for your health and safety while building or operating the printer. Ensure you are confident with the process before commencing. Read the entire manual to make an informed decision.
Building and operating involves electricity. All necessary precautions should be taken. The printer runs on 12V supplied by a certified power supply. Be aware that high currents can be involved, and even 12V components should be handled with care.
High temperatures are involved with 3D Printing. The extrusion nozzle of the hot end can reach approximately 230°C, and the heated bed can reach 110°C. The molten plastic extruded will initially be around 200°C. Special care and attention should be given when handling these parts during operation.
It is not recommended to leave your printer running unattended until you are confident in its operation. Geeetech cannot be held responsible for any loss, damage, threat, hurt, or other negligent result from building or using the printer.

General Care and Maintenance
As with all electronic equipment, it is important to keep your printer clean to extend its life. Regularly remove dust and debris with a microfiber cloth or compressed air. Clean the tube and the nozzle after each use to ensure fluent performance.
- Do not leave the heaters on the printer turned on for long periods when not used.
- Do not leave your printer in shady and moist places, which may exacerbate problems associated with erosion.
- The three axes of the Geeetech I3 Pro B are lubricated with grease for smooth operation and can last for a long time. Grease may need to be re-applied to maintain smooth performance.
- Avoid positioning your power supply unit in such a way that the brick is hanging, pulling, or putting unnecessary stress on the electrical wires and components.
