To ensure the best possible fit, a dentist will take a 3D image of the patient’s mouth. A reverse mold is created, and ultrasoft bristles are attached. To use it, bite and grind teeth on the toothbrush 15 times. It only takes 6 seconds, but is efficient enough that it could eliminate the need for flossing. Over the course of the year, it saves 55 hours of brushing time.

This is so fucking cool…holy shit.

A group of high school students in Sicily invented a vending machine that turns trash into phone cases. The machine grinds plastic bottles into pellets, which are melted down to be reused by a 3D printer that creates a variety of phone cases and encourages students to recycle more. Source Source 2

A Pen That 3-D Prints Bone Right Onto Patients

The device could eventually let surgeons apply stem cells more directly 

One of the greatest promises of 3-D printing is that we’ll one day be able to print organs on-demand. Need a new liver? There it is, at the push of a button.

Anticipating that future, scientists from the University of Wollongong in Australia have created the BioPen, a tool that lets physicians more or less draw new bones on peoplethrough 3-D printing. The pen is loaded with so-called “stem cell ink,” a batch of human cells that can form new bone. Another second substance, a polymer, then seals the area so the stem cells can do their work in peace. You can see why this is promising: if someone loses parts of bone in an accident, a tool like this pen could apply a fix directly to the problem area.

We've seen 3-D printed bones before, actually, but this device could give a little more precision. It’s yet to undergo clinical testing, so it still may be a while before it hits the market, but if and when it does, it’ll have some company


3D Printed Cast Design Heals Patients 40% Faster

A Turkish student has designed a 3D printed cast prototype that could help speed up the healing process by 40% when worn. The prototype, called Osteoid, utilizes proven healing benefits from low-intensity pulsed ultrasound. Its design focuses on comfort and improvement of overall healing for the patient.

British Museum releases scans of artefacts to let you 3D print your own museum at home

The British Museum could soon be coming to your living room – if, that is, you have a 3D printer on hand.

Working in collaboration with Sketchfab, an online platform that lets users share and download 3D scans, the British Museum has created 14 3D models of busts, statues and sarcophagi from its collection for anyone to download and print at home.

The museum’s “first downloadable collection” includes a granite head of Egyptian pharaoh Amenemhat III from the 12th Dynasty (around 1800 BC), a stone figure of the Aztec god Ziuhcoatl (created around 1325-1521 AD) and a marble bust of Zeus of 1 century origin that is described as “found/acquired” -nicer than stolen/nicked - from Roman emperor Hadrian’s Villa.

Amazing 3D Grass Printer Makes Creative Gardens Possible

Students Maja Petek, Tina Zidanšek, Urška Skaza, Danica Rženičnik and Simon Tržan at the University of Maribor in Solevnia designed an innovative “green” 3D printer to aid their mentor Dušan Zidar. The purpose of the machine is to construct creative designs varying in different shapes and sizes to fully express inventive compositions for gardening. Titled PrintGREEN, the apparatus is a modified CNC machine, which deposits soil, seeds, and water, instead of plastic or metal. With the aid of the PrintGreen, one can compose fun shapes and sizes to create the ideal garden.
