Hazards
Hot Tool Head – The 3D printer’s tool head (nozzle) operates at extremely high temperatures, often around 400°F (200°C)—similar to the inside of a hot oven. Touching it during or shortly after printing can cause severe burns. Always wait for the nozzle to cool down before performing any actions.
Molten Plastic – The plastic filament is melted during printing and reaches very high temperatures. Contact with molten plastic can cause burns or skin damage. Avoid touching freshly extruded filament or removing melted plastic with your hands.
Moving Gears and Belts – The printer’s gears, belts, and extruder mechanisms are constantly moving during operation. These parts can lead to pinching or entanglement injuries. Always keep hands and loose items away from moving parts while the printer is running.
Additional Risks – Some filaments release fumes when heated. Printing in a well-ventilated area or using proper filtration is recommended, especially with materials like ABS.
How can we avoid injury?
Avoid Contact with Hot Surfaces – Never touch the tool head or heated bed while the printer is operating or immediately after a print finishes. Both remain extremely hot and can cause severe burns. Wait until they have fully cooled before handling.
Do Not Touch Plastic Mid-Print – The filament is extruded at very high temperatures. Avoid touching molten plastic or trying to remove it by hand while the printer is running.
Secure Hair and Clothing – Tie back long hair, avoid wearing loose clothing, and remove dangling jewelry. These can easily get caught in moving gears, belts, or the extruder.
Stay Alert Around Machinery – Treat the printer like any other piece of equipment: be mindful of moving parts, don’t reach into the printer while it’s operating, and keep your hands clear of the tool head and build area.
General Safety – Always use common sense, maintain awareness of your surroundings, and operate the printer in a clean, organized space.
