Chemical and Fire Safety

Operating a 3D printer can involve handling chemicals for cleaning and post-processing. It's also important to be prepared for the very low, but not zero, risk of fire associated with any high-power electrical appliance.

Chemical Safety

Commonly Used Chemicals

Tasks like cleaning the print bed or smoothing parts may involve using chemicals like Isopropyl Alcohol (IPA) and Acetone. These substances require careful handling.

Safe Handling Guidelines

  • Ventilation: Always use chemicals in a well-ventilated area to avoid inhaling fumes.
  • Skin Contact: Avoid direct skin contact. It is highly recommended to wear nitrile gloves when handling solvents like acetone or IPA.
  • Storage: Keep chemicals in their original, clearly labeled, and tightly sealed containers. Store them away from heat sources, sparks, or open flames, as they are flammable.
  • Disposal: Dispose of used chemicals and any cloths or paper towels soaked in them according to your local regulations. Do not pour them down the drain.

Fire Safety

Fire Risk and Prevention

The single most important fire prevention step is to never leave your printer operating completely unattended. While safety features exist, any electrical device that generates heat carries a potential fire risk.

In Case of Fire

Being prepared can prevent a small problem from becoming a disaster.

  • Do NOT Use Water: Never use water to extinguish a fire on an electrical device. It can cause electrocution and spread the fire.
  • Disconnect Power: If it is safe to do so, disconnect the printer from the power outlet.
  • Use a Suitable Fire Extinguisher: It is highly recommended to keep a fire extinguisher rated for electrical fires near your printing area.

Recommended Fire Extinguisher Types

Look for an extinguisher rated for the following classes: * Class C: Specifically for energized electrical equipment. * Class ABC (Dry Chemical): This is the most common multi-purpose type and is effective on electrical fires (Class C), as well as common combustibles (Class A) and flammable liquids (Class B).
