Arthur T Knackerbracket has found the following story:

Ultraprecise 3-D printing technology is a key enabler for manufacturing precision biomedical and photonic devices. However, the existing printing technology is limited by its low efficiency and high cost. Professor Shih-Chi Chen and his team from the Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong (CUHK), collaborated with the Lawrence Livermore National Laboratory to develop the Femtosecond Projection Two-photon Lithography (FP-TPL) printing technology.

By controlling the laser spectrum via temporal focusing, the laser 3-D printing process is performed in a parallel layer-by-layer fashion instead of point-by-point writing. This new technique substantially increases the printing speed by 1,000—10,000 times, and reduces the cost by 98 percent. The achievement has recently been published in Science, affirming its technological breakthrough that leads nanoscale 3-D printing into a new era.

    The improved technique is usable in nano-scale printing.
    Joe Average using a RepRap printer will still wait for hours.

    Using an enormous array of nanoscale printers to print my centiscale plastic junk is the killer app.

      I just came to have a look at what's happened to this site since its inception. No controversial stories whatsoever, nothing with grit. Shame to see all the hard work come to this.

        It's Christmas time, dummy.
