3D Printing’s 2014 Renaissance (Quartz) — patents on sintering about to expire which will open up hi-res production. Happened in the past when patents on fixed deposition modelling expired: Within just a few years of the patents on FDM expiring, the price of the cheapest FDM printers fell from many thousands of dollars to as little as $300.
Ultrafine Particle Emissions from Desktop 3D Printers (Science Direct) — Because most of these devices are currently sold as standalone devices without any exhaust ventilation or filtration accessories, results herein suggest caution should be used when operating in inadequately ventilated or unfiltered indoor environments.

Aireal — focussed changes in air pressure simulate sensations of touch. The machine itself is essentially a set of five speakers in a box–subwoofers that track your body through IR, then fire low frequencies through a nozzle to form donut-like vortices (I imagine the system as a cigar-smoking Microsoft Kinect). [...] In practice, Aireal can do anything from creating a button for you to touch in midair to crafting whole textures by pulsing its bubbles to mimic water, stone, and sand. (via BoingBoing)
