3D Printing Safety What You Need to Know 3D printing is a fascinating technology that allows you to create physical objects from digital models. However, like any other technology, it also comes with some potential risks and hazards that you should be aware of and avoid. In this article, we will discuss some of the most common health and safety considerations during 3D printing and how to prevent them. 1. Toxic Fumes from Materials One of the main concerns of 3D printing safety is the emission of toxic fumes from the materials used in the process. Depending on the type of filament, resin, or powder you use, 3D printing can release small vapors or particles into the air that may be harmful to your health if inhaled. Some of the most common materials that emit fumes are acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), and nylon1. These fumes may cause irritation, headache, nausea, or respiratory problems2. To avoid exposure to toxic fumes, you should always print in a well-ventilated area or use an enclosure with a filter or fan to capture the emissions. You should also wear a mask or respirator when handling the materials or the printed objects. Consult the safety data sheets (SDS) of the materials you use to understand and evaluate the specific health and safety hazards associated with them3. 2. Electric Shocks Another risk of 3D printing safety is electric shock. 3D printers use electricity to power the motors, heaters, fans, and other components. If there is a faulty wiring, a short circuit, or a power surge, you may get electrocuted by touching the printer or the power cord. Electric shocks can cause burns, muscle spasms, cardiac arrest, or even death2. To prevent electric shocks, you should always check the condition of the printer and the power cord before using them. You should also avoid touching the printer or the power cord when they are plugged in or turned on. If you notice any sparks, smoke, or smell of burning, you should immediately unplug the printer and contact the manufacturer or a qualified technician. You should also follow the standard safety guidelines for electrical equipment3. 3. Scraper Blades Another hazard of 3D printing safety is scraper blades. Scraper blades are tools that are used to remove the printed objects from the print bed. However, they are also very sharp and can cause cuts, lacerations, or punctures if handled improperly. Scraper blades can also damage the print bed or the printer if used with too much force or at the wrong angle. To avoid injuries from scraper blades, you should always wear gloves and eye protection when using them. You should also use them gently and carefully, and avoid applying too much pressure or scraping too fast. You should also store them in a safe place away from children and pets. You should also clean the print bed and the scraper blade after each use to prevent the accumulation of residue or debris.
