Now, five years later, the team has improved their printing machine and method, and can produce objects made out of opaque resin\u2014something that was never before possible.<\/p>\n<p><b>A tiny Yoda<\/b><\/p>\n<p>EPFL&#8217;s 3D printer is one of the fastest in the world. Whereas most 3D printers work by depositing a material layer by layer in a process known as additive manufacturing, the EPFL one uses a volumetric method. &#8220;We pour the resin into a container and spin it,&#8221; says Christophe Moser, a professor at LAPD. <\/p>\n<p>&#8220;Then we shine light on the container at different angles, causing the resin to solidify wherever the accumulated energy in the resin exceeds a given level. It&#8217;s a very precise method and can produce objects at the same resolution as existing 3D-printing techniques.&#8221; The engineers&#8217; volumetric method can be employed for objects of just about any shape, and they decided to test it by creating a tiny Yoda. It took just 20 seconds for them to make the figurine, versus around ten minutes for a conventional additive-manufacturing process.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/objects-can-now-be-3d-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/objects-can-now-be-3d-1.jpg\" data-sub-html=\"Three 3D-printed objects: one made from transparent resin (left); one from opaque resin, without correction (middle); and one from opaque resin, with correction (right).

First, they used a video camera to observe the light&#8217;s trajectory through the resin and then designed computer calculations to compensate the light-ray distortion. They programmed their printer to run these calculations and correct the light rays as the printer operates. This made sure that the amount of energy needed to solidify the resin would be reached at the desired spots. By adjusting the computer calculations, the engineers were able to print objects in opaque resin with almost the same precision as for transparent resin\u2014an important breakthrough.<\/p>\n<p>The LAPD method can be used to 3D-print biological materials, such as artificial arteries. As a next step, the engineers hope to be able to print several materials at once and increase their printer&#8217;s resolution from one-tenth of a millimeter to a micrometer.
