Trends in 3D printing technology
3D printing can help reduce waste, for example by replacing only a damaged part rather than an entire product, reducing the amount of new material needed.
Printing materials have also developed, with growing attention to biodegradability and environmentally considerate processing. Biodegradable polymers are one area of interest.
Degradable metals offer further possibilities for industry and healthcare.
Other directions include fully automated 3D printing, intelligent printers and connections to the Internet of Things.
