As expected, 3D printing continued to grow in popularity during 2020 with an increase of new machines, techniques, materials and resources. Here's a look at what we saw this year.
First off, some information: MakerBot released a 3D Printing Trends Report featuring statistics gleaned from "over 1,200 responses from professionals across multiple industries, including Aerospace, Industrial Goods, Military & Defense, Medical, and Automotive." As one example, we learned that most designers prize reliability over accuracy when it comes to choosing a machine.
A collaboration between the Wyss Institute and the Harvard School of Engineering and Applied Sciences yielded a new technique called Multimaterial Multinozzle 3D printing. Their revolutionary method can change the filament's color as it's being extruded.
This year the NASA 3D Resources website posted hundreds of 3D models, images, textures and visualizations that you can download for free. The Printable section has .stl files you can use to print things like their Multi-Purpose Precision Maintenance Tool.
