3D printing technology has been widely used in multiple fields due to its innovation and convenience. However, safe use of 3D printers is crucial to ensure the safety of operators and the normal operation of equipment. This article provides a detailed safety operation guide to help users use 3D printers safely.
Choose the right 3D printing equipment and materials
When choosing a 3D printer, you should choose a brand and product that has passed quality certification to ensure that the equipment meets relevant safety standards. At the same time, understand the characteristics and safety of the printing materials, and avoid using harmful substances or low-quality materials. Different materials may require different printing temperatures, pressures, and speeds, so carefully read the instructions for use of the materials.
Preparation before printing
Ventilation environment: Choose a well-ventilated workspace to avoid long-term exposure to the odor of printing materials. Some materials will release harmful gases during the heating process, so it is recommended to place the printing equipment in a well-ventilated place or use a special exhaust device.
Protective Equipment: Wear appropriate protective goggles, gloves, and masks to avoid direct contact with printing materials and equipment. Especially when using knives or cleaning chemicals, appropriate protective equipment must be worn.
Model preparation: On the computer, the 3D model to be printed will be stored in the STL format file by the software to the specified folder.
Parameter settings: When setting print parameters, make sure they are within the applicable range.
Security during printing
Avoid touching high temperature parts: during processing or just after processing, the spinning nozzle is in a high temperature state, and any part of the body is prohibited from touching the part.
Observe the operation: pay attention to observe the operation of the 3D printer, if there is a problem, solve it in time or shut down.
Keep the environment clean: Keep the environment around the 3D printer clean to ensure that there is no debris and no oil.
Operation after printing
Waiting for cooling: After the equipment spinneret returns to its original position, the temperature drops to below 50 ℃ before cleaning and other operations.
Use tools to pick up: In the process of picking up, the platform should be lowered to the appropriate position as required, and try not to scratch the printer baseplate with a small shovel.
Proper disposal of waste: Proper disposal of waste generated during the printing process, such as material residues and wastewater, to avoid pollution and harm to the environment.
Maintenance and upkeep
Clean nozzle motor: It is recommended that users clean the nozzle motor once after 1 month of normal use, and once every half month for high-intensity use.
Maintenance of optical axis: It is recommended to lubricate and maintain the optical axis after 2 months or when the printer noise increases.
Maintenance of Z-axis wire rod: If the noise increases when the Z-axis platform operates up and down, it can be maintained with oil or ordinary lubricating oil.
Maintenance of synchronous pulley fixing screws: Regularly check the synchronous pulley fixing screws to ensure their fastening.
Environmental and equipment requirements
Placement location: Avoid placing in places where temperature and humidity are prone to drastic changes, stay away from dusty areas, avoid direct sunlight, strong light or heat sources.
Power requirements: Connect the power cord directly to the wall socket, do not use extension cords, do not use damaged or flawed power cords. Be sure to connect the ground wire at the installation position.
Avoid flammable items: Avoid exposing the printer to flammable liquids, gases, and aerosols to prevent fire or electric shock.
Other notes
Software and firmware upgrades: Regularly upgrade software and firmware to improve printing performance and user experience.
Correct shutdown and storage: When stopping the use of the 3D printer, make sure to shut it down correctly and store it according to the manufacturer’s guidelines.
Conclusion
3D printing technology brings us the joy of creativity and personalized design, but we must also pay attention to the safety issues of 3D printing. By choosing suitable equipment, operating and maintaining equipment correctly, and following safety operation guidelines, we can maximize the balance between creativity and safety. At the same time, when an emergency occurs, we need to respond calmly and seek professional help in a timely manner. Let’s work together to enjoy the fun of 3D printing while ensuring safety and worry-free.
