3D printers are intricate devices, bundled with safety protocols every trainee needs to heed. I’ve crafted a handy guide on these precautions to ensure you remain safe during your 3D printing adventures. Your safety lies in your hands, so dive deep into these before kickstarting your 3D printing. Our emphasis here is mainly on FDM printers, as they’re distinct from those using liquid resin.

1. Be Vigilant of Burns
A well-known fact among 3D printing enthusiasts is the extreme heat these printers operate under, from the printing surface to the nozzle. These filaments get melted to form layers upon layers of your design. Touching any part of the printer during operation can lead to painful burns.
Many have inadvertently touched the hot parts while adjusting or refilling the filament, resulting in painful injuries. However, with a mindful approach, such accidents can easily be prevented. Certain FDM printers come equipped with a heating bed to aid in the initial layers of printing. As exciting as the process is, prioritizing safety is crucial.
How to reduce burn risks:
– Place your printer in a secure and less frequented spot.
– Don protective gloves while tinkering with your printer.
– Opt for printers with enclosures or craft your own.
– Constantly remind yourself about the heat your printer can produce.
2. Steer Clear of Pinching Injuries
3D printers involve significant mechanical motion across the X, Y, and Z axes. These precise movements can inadvertently trap or pinch your fingers if you’re not careful. While some printers have collision detection mechanisms to prevent such issues, many do not. So, always remember that printer movements can be unpredictable.
How to diminish pinch point injuries:
– Use protective gloves.
– Have an enclosure around your printer.
– Engage with your printer only when it’s powered off.
3. Handle Scraper Blades with Care
Scrapper blades, though essential for post-printing tasks, can be quite hazardous if not used cautiously. A slight slip can lead to serious injuries. Hence, always handle them with utmost care.
How to curb scraper blade injuries:
– Always scrape in a direction away from yourself.
– Keep both hands behind the blade’s edge.
– Employ durable gloves when detaching your prints.
4. Stay Shielded from Electrical Hazards
Although not widely acknowledged, electrical risks associated with 3D printers are real. Various factors, like faulty grounding or loose wiring, can electrify your printer’s frame.
How to lessen electric shock dangers:
– Ensure proper grounding for your 3D printer.
– Ensure your mains power has an earth connection.
– Always ensure a humidity range of 20%-30% to mitigate static.
5. Prevent Fire Dangers Proactively
Even though most modern 3D printers are equipped with safety mechanisms to prevent fires, it’s always good to be prepared.
How to combat fire hazards:
– Confirm that your printer has thermal runaway protection.
– Fireproof the printer’s surroundings.
– Stay away from DIY printer kits if you lack the expertise.
– Install smoke detectors nearby.
6. Safely Detach Support Structures from Final Outputs
PLA structures, especially, can pose a threat when trying to remove them. The sharp edges can cause injuries if not handled correctly.
How to lessen injuries when removing supports:
– Opt for software that minimizes support use.
– Proceed slowly when removing supports.
– Wear protective gloves during the process.
7. Stay Informed about Potentially Harmful Emissions
Certain printing materials can emit harmful fumes. It’s essential to keep your printing space well-ventilated and be informed about the materials you’re using.
How to cut down on the hazards of dangerous fumes:
– Ensure adequate ventilation around your printing area.
– Invest in air purifiers with HEPA filters.
– Prioritize materials known for lesser emissions, like PLA.
Safe and sound printing to you all!
