There are tons of filament and resin options available for 3D printing today, but we've never come across one like this. Researchers at the University of Texas at Austin have developed a new 3D printing technique (spotted by New Atlas) that makes it possible to print both hard and flexible materials at the same time using just one resin.
This process not only lets you manufacture two different hardnesses of 3D printed materials, but also print the two together. This means the hard and soft materials are printed as one and don't have to be fused together separately after printing. The process uses a custom UV printer that's built to deliver different wavelengths to create the variations in rigidity.
