Invisible Particles: Microplastics from 3D Printing – Risks, Realities and Responsible Solutions
The transformative power of 3D printing or additive manufacturing (AM) is undeniable. From complex prototypes to custom medical devices, it is reshaping the manufacturing landscape. Yet beyond the plastic wonders it creates, a less obvious but growing concern also arises: Microplastic pollution is directly generated by the printing process itself. At GreatLight, as a leader in advanced metal additive manufacturing solutions such as Selective Laser Melting (SLM), we delve into this complex issue, tying environmental responsibility to technological advancement.
Beyond finished printing: Understanding the microplastic footprint
When we discuss plastic pollution, images of ocean gyres clogged with bottles often appear. However, the origins of microplastics (defined as plastic particles less than 5 millimeters in size, and nanoplastics less than 1 micron in size) are more recent than many realize, including our own labs and workshops:
- Filament wear and tear:
