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"
Forbes senior contributor, TJ McCue, has been keeping an updated list of various corporate and maker/makerspace initiatives to 3D print filter masks and face shields for healthcare workers.
The ever-clever and resourceful Danielle Baskin has created a site for the online coordination and distribution of DIY-produced filter masks, face shields and other PPE (personal protective equipment). In times of emergency, the CDC allows production for crisis capacity scenarios. Homemade supplies are an emergency supply for overwhelmed hospitals and we have to prepare right […]
Last week, I reported on Czech 3D printer company, Prusa Research, converting over some of their manufacturing capability to producing hand sanitizer. Now, the company has, within three days of prototyping, created a 3D printable face shield. Josef Prusa writes: We were notified on Facebook that doctors are in great need of face shields and […]
At this point, it’s every single person’s responsibility to reduce their own carbon footprint and transition to a more sustainable lifestyle. But if you consider the grim fact that the biggest culprit of greenhouse gas emissions from human activities in the U.S. is burning fossil fuels for electricity, things, like pivoting to metal straws and […]
Companies that don’t have their own in-house design teams (which means 99 percent of all companies these days) face lots of serious questions. Among those questions is how you keep up with all the design requirements of a 21st-century company without the personnel. It isn’t just a website or an annual product catalog anymore. It’s […]
In case you’re one of those computer shoppers who instinctively turns up their nose at the very mention of the word refurbished, here are a couple myths worth dispelling. Refurbished equals junk somebody didn’t want. While desktops, laptops, notebooks, Chromebooks and tablets marked as refurbished may have been unboxed at some point, meaning they can […]
