    Ultra-thin optical film sharpens 3D printing precision
    Researchers designed and fabricated a double-sided structure collimation film (DSSCF) with better collimation characteristics thanks to additional trapezoidal microstructures that prevent the large-angle leakage light seen with single-sided structure collimation film (SSSCF). The DSSCF also improves the light intensity uniformity when combined with a diffuser module. Credit: Ding-Zheng Lin, National Taiwan University of Science and Technology

    Researchers have developed an ultra-thin optical film that improves the quality of the light used in LCD resin-based 3D printers. The advance helps ensure that tiny details are reproduced with precision, which could make it possible to 3D-print medical-grade or industrial-grade products at a lower cost.

    Medical valves manufactured with portable 3D printers are saving the lives of coronavirus victims at a hospital located in what is considered Italy’s Ground Zero for the deadly viral infection.

    When the founder of Issanova, a startup 3D printing firm with a staff of 14 learned that a local hospital was running short of critical breathing devices used to help hospital patients suffering from the deadly virus, he sprang into action. He consulted with a fellow engineering expert and the two raced to the desperate hospital located in the small town of Chiari. There, they examined the medical device, called a Venturi valve.

    That was on Friday the 13th...
