    My brother’s lab (not at MIT) has been 3D printing optically clear glass for years. They can do all sorts of shapes and figures, though I’m particularly fond of the Yoda heads. If I’m reading this article correctly, the breakthrough they made was with the temperatures they can do it at, and it’s much less to do with the novelty of 3D printing glass. So it’s much less “hey, this is amazing, nobody has ever done this before,” and far more “we did this cool thing in a new and harder way!”

      Low temp has a lot of implications for spreading this technology. Being able to print complex glass shapes at low temperatures can open up all kinds of cool applications that wouldn’t be possible at high temps.

    250C is not low temp for 3D printing tho, noticed that in headline.

    sure that is low temp for glass aber above the PLA, ABS, ASA temps i run in vorons.

      Whut? Basically every 3D printer does print way above that (300°+X is the industrial norm for more advanced new printers now e.g. Centauri Carbon, Artillery M1 Pro, BL, etc.). 250° is absolutely nothing out of the ordinary these days and can be achieved by basically every 3D printer a major brand brought out in the last two years. Even the A1mini can do so.

      Polymaker’s ASA is recommended to be printed at 250° and Formfuturas ASA, BL ABS, Formfutura ABS(reTitan), Fiberology, For Polymakers ABS the lowest temp recommended starts at 245°C, goes up to 265.

      Most Nylons, PCTG start above 250°C as well. And let’s not even start about proper high Temperature materials like PEEK,ULTEM,PEI.

      Don’t get me wrong,but maybe your temp sensor is off(not unheard off in Vorons) or your settings are off. I have yet to see someone get ASA printed well with settings well below the recommendations.

      They stated 250C was for annealing to final product. That’s a temperature any bog standard toaster oven or kitchen oven can do. Sadly, they said nothing I saw about actual extrusion temps.

      Glass (some not all) melts at more than 1000 C I think that’s hell of a lot harder to print at than 250 C even Prusa PETG prints at that temp.
