3D printing has come a long way since it first appeared on the scene. Now, researchers have found that 3D printed materials can become contaminated by particles in the air, leading to potential health risks. Researchers from the University of Nebraska-Lincoln conducted a study which looked at samples of 3D printed material to see how much contamination was present. The results showed that the 3D printed material was contaminated with airborne particles, including metals, bacteria, and fungi. The particles can potentially cause health risks if inhaled or ingested. The researchers suggest that regulations and guidelines be put in place to ensure the safety of 3D printed materials.
