Additive manufacturing, or 3D printing, is normally a one-way street. In a digital light processing (DLP) printer, a structured pattern is projected onto a layer of liquid resin, which cures and solidifies. This builds an object up, layer-by-layer. But if the print isn\u2019t exactly right, there\u2019s no easy way to fix it after the fact: it usually ends up in the trash.<\/p>\n

In a new study, published in Advanced Materials Technologies<\/i><\/a>, researchers at Lawrence Livermore National Laboratory (LLNL) developed a hybrid additive and subtractive manufacturing system with a unique resin<\/a> that enhances traditional 3D printing by introducing dual-wavelength behavior. Under blue light<\/a>, the resin cures and hardens. Under ultraviolet light<\/a>, it degrades back into a liquid. The hybrid printing system enables corrective manufacturing, provides improved print resolution and allows for upcycling and recycling of parts.<\/p>\n

\u201cImagine if a company needed a part to fit a certain machine but it\u2019s a prototype and they\u2019re not quite sure what they want,\u201d said LLNL scientist and author Benjamin Alameda. \u201cThey could theoretically print with our resin. And if there were defects or something they wanted to change about it, they don\u2019t have to print a whole new part. They could just shine another wavelength on it and modify the existing part. That\u2019s useful and less wasteful.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
