It's now possible to 3D print extremely viscous materials, with the consistency of clay or cookie dough with fine precision. This development may soon allow the creation of customized ceramics, solid rockets, pharmaceuticals, biomedical implants, foodstuffs, and more.
The researchers' Expert-Guided Optimization (EGO) method combines expert judgment with an optimization algorithm that efficiently searches combinations of parameters relevant for 3-D printing, enabling high-fidelity soft material products to be printed.
Researchers used laser 3D metal printing to optimize a permanent magnet material that may make an economical alternative to the more expensive rare-earth neodymium iron boron magnets in some applications.
Engineers built a 3-D printer that offers a sweet solution to making detailed structures that commercial 3-D printers can't: Rather than a layer-upon-layer solid shell, it produces a delicate network of thin ribbons of hardened isomalt, the type of sugar alcohol used to make throat lozenges.
Bioengineers have developed a technique that uses a specially adapted 3D printer to build therapeutic biomaterials from multiple materials. The advance could be a step toward on-demand printing of complex artificial tissues for use in transplants and other surgeries.
