How can you safely handle printing materials and fumes?

1 Choose the right material

Different 3D printing materials have different properties and risks. Some are more toxic, flammable, or prone to emit harmful fumes than others. For example, ABS (acrylonitrile butadiene styrene) is a common plastic that can release volatile organic compounds (VOCs) and styrene, which can cause headaches, nausea, and respiratory irritation. PLA (polylactic acid) is a biodegradable material that is generally safer, but can still produce ultrafine particles (UFPs) that can affect the lungs and the cardiovascular system. You should always check the safety data sheet (SDS) of the material you are using and follow the manufacturer's recommendations.

2 Ventilate the printing area

One of the most important steps to reduce the exposure to printing fumes is to ensure proper ventilation of the printing area. You can use a fan, a window, or an exhaust system to create airflow and remove the fumes from the room. You can also use a filter or a hood to capture the fumes and prevent them from spreading. Some 3D printers have built-in filters or hoods, but you can also buy or make your own. You should also avoid printing in a small, enclosed, or crowded space, and keep a safe distance from the printer while it is operating.

5 Clean the printer and the printing area

Finally, you should clean the printer and the printing area regularly to maintain their performance and safety. You should remove any dust, debris, or residue from the printer's parts, such as the nozzle, the bed, the extruder, and the fans. You should also wipe down the printer's surface and the printing area with a damp cloth or a mild cleaner. You should avoid using harsh chemicals, abrasives, or solvents that can damage the printer or create fumes. You should also unplug the printer and let it cool down before cleaning it.

6 Educate yourself and others

The last tip to safely handle printing materials and fumes is to educate yourself and others about the potential risks and benefits of 3D printing. You should read and follow the instructions and warnings of the printer and the material manufacturers, and consult reliable sources of information and advice. You should also share your knowledge and experience with other 3D printing enthusiasts, and encourage them to adopt safe practices and habits. By doing so, you can enjoy 3D printing without compromising your health or the environment.
