Dexterity Hand is a Configurable Prosthetic Hand | Hackaday
One of the interesting benefits of the 3D printing revolution is the dramatic increase in availability of prosthetics for people with virtually any need. With a little bit of research, a 3D printer, and some trial and error, virtually anyone can build a prototype prosthetic to fit them specifically rather than spend thousands of dollars for one from a medical professional. [Dominick Scalise] is attempting to flesh out this idea with a prosthetic hand that he hopes will be a useful prosthetic in itself, but also a platform for others to build on or take ideas from. The idea that sets this prosthetic apart from others, however, is its impressive configurability while not relying on servos or other electronics to control the device. The wearer would use their other hand to set the dexterity hand up for whatever task they need to perform, and then perform that task. Its versatility is thanks to a unique style of locks and tensioners which allow the hand to be positioned in various ways, and then squeezed to operate the hand. It seems like a skilled user can configure the hand rapidly, although they must have a way to squeeze the hand to operate it, or someone will need to develop an interface of some sort for people without needing to squeeze it.

Heated DryBox Banishes Filament Moisture for Under $20 | Hackaday
There has been a lot of activity from [Richard Horne] regarding 3D printing filaments lately; most recently he has shared two useful designs for upping one’s filament storage and monitoring game. The first is for a DIY Heated DryBox for 3D printing filament. It keeps filament dry not just by sealing it into a plastic box with some desiccant, but by incorporating a mild and economical heater intended for reptile habitats inside. Desiccant is great, but a gently heated enclosure can do wonders for driving away humidity in the right environment. The DryBox design also incorporates a handy little temperature and humidity sensor to show how well things are working.

3D.FAB bioprint “living bandage” within regenerative medicine research project
Clinicians of various specialties require autologous implantable tissues to repair and replace damaged tissue caused by diseases or trauma. With 3D bioprinting it is possible to manufacture such tissues, however, its biomechanical characteristics reduce its capabilities to be sutured.

As a result, 3D.FAB, a French additive manufacturing platform, is developing a “living bandage” using 3D bioprinting and direct additive manufacturing. According to the platform’s project “STRESSKIN,” such technologies can be positioned in this field of regenerative and personalized medicine to address this issue.

3D Printing - The New Way to Build Disaster Resistant Housing! | Sunconomy
For thousands of years, we have built houses the same way using sticks, bricks, stones, mud, and thatch. Ask yourself why? Is it because these materials are structurally superior? No way! It’s because they are readily available, easier to work with, and easier to put together. That doesn’t mean they are better, nor will they last longer or that they will take less maintenance. They definitely won’t last as long as the newer geopolymer concrete.
