Jackie Anderson offers a review regarding one of the most critical 3D printing topics today: materials. As innovation continues to grow, so do the options regarding software, hardware, and different types of plastics (along with many other alternatives today).
In ‘Engineering Biodegradable PHA Blends,’ Anderson explores issues with plastic waste, and the need to use more environmentally friendly materials as 3D printing filaments.
While other plastics such as acrylonitrile butadiene styrene (ABS) are often used in 3D printing, bioplastics like polylactic acid (PLA) are popular due to their ability to biodegrade, but still, there are other materials superior in that area; in fact, previous research has shown that thin films of other bioplastics like polyhydroxyalkanoates (PHA) may degrade in as little as 1.2 to 2.4 months. This is promising in eliminating the amount of waste that could emerge from 3D printing discards, with Anderson reminding us that plastics can take ‘hundreds to thousands of years to degrade,’ causing harm to every living creature.
