It's historically been tough and slow-going to 3D print objects made from multiple materials. Now, Harvard researchers developed an ingenious nozzle that enables the 3D printer to spew out eight different materials at the resolution of a human hair. To demonstrate the system, they printed fantastic flexible origami structures and even a "soft" robotic millipede from a variety of epoxy and silicone elastomer inks. Mark A. Skylar-Scott, Jochen Mueller, and their colleagues from Harvard's Wyss Institute for Biologically Inspired Engineering presented their work in the scientific journal Nature: "Voxelated soft matter via multimaterial multinozzle 3D printing"
3D printing is a dumpster fire of stupid, obvious patents, but thankfully many of these are expiring; this year, the stupid patent on putting sides on a 3D printer (extrusion printers are very sensitive to errant breezes and just a puff of wind can ruin a print that took hours, just minutes before it completes).
I've been semi-seriously joking about "AK-3DPs" (3D printed assault rifles) for years, and while the attempts to limit the spread of 3D printed guns have been sloppy and poorly formulated (as have the Trump admin's attempt to roll them back) the state of the art is still progressing.
"Improving Automobile Safety by Removing Blind Spots" is 14 year old Alaina Gassler's prizewinning science-fair project, which uses cameras mounted to the exterior of the car and feeding their video to internal projectors, which projection-map them onto the a-pillars that otherwise obscure the driver's view.
There’s much ado about coffee brewing methods these days, but most of us – at least on the busy weekdays – just want our morning joe to be consistent, easy, and most of all, fast. If that sounds like anyone on your Christmas list, they’re going to get a lot of mileage out of the […]
Online shopping is going to be through the roof this month, and you’d better believe that hackers know it. If you’re going to invest in a virtual private network, now is the time. Especially when Windscribe VPN is offering its own holiday discount. At their current price point, it’s well worth jumping on the paid […]
Cheap massage chairs are a common Christmas gift, but we’re willing to bet they don’t get a lot of actual use from the people who could really use a massage. We’re talking about people with deep, chronic joint pain or anyone who does a serious workout on a regular basis. For that kind of soreness, […]
