New 3D-Printing Method Enables Complex Designs, Creates Less Waste
Researchers have developed a resin that turns into two different kinds of solids, depending on the type of light that shines on it: Ultraviolet light cures the resin into a highly resilient solid, while visible light turns the same resin into a solid that is easily dissolvable in certain solvents.
Hearing aids, mouth guards, dental implants, and other highly tailored structures are often products of 3D printing.
