3D printed sundial projects digital time

Mojoptix designed and built a sundial that displays the time in its shadow. You can download the 3D printer files on Thingiverse, or buy one on Etsy.

Fun fact about this sundial: You will most likely never see it in a supermarket or a department store. The swiss cheese inside the sundial is so intricate, that you can’t realistically use injection molding, or some other mass-production method. 3D printing seems actually to be the only practical way to build this digital sundial ! (is that really true ?? let me know what you think in the comments !)

MIT researchers 3D print synthetic hairs

MIT Media Lab researchers developed software to design and 3D print hair-like structures in bulk. Eventually, the 3D-printed hair could be used as sensors, actuators modeled on the cilia in our own lungs, and even Velcro-like adhesives for robots and other devices.

Their innovation was actually on the software side of the 3D-printing process. From MIT News:

Instead of using conventional computer-aided design (CAD) software to draw thousands of individual hairs on a computer — a step that would take hours to compute — the team built a new software platform, called “Cilllia,” that lets users define the angle, thickness, density, and height of thousands of hairs, in just a few minutes.

Using the new software, the researchers designed arrays of hair-like structures with a resolution of 50 microns — about the width of a human hair. Playing with various dimensions, they designed and then printed arrays ranging from coarse bristles to fine fur, onto flat and also curved surfaces, using a conventional 3-D printer...

To demonstrate adhesion, the team printed arrays that act as Velcro-like bristle pads. Depending on the angle of the bristles, the pads can stick to each other with varying forces. For sensing, the researchers printed a small furry rabbit figure, equipped with LED lights that light up when a person strokes the rabbit in certain directions. And to see whether 3-D-printed hair can help actuate, or move objects, the team fabricated a weight-sorting table made from panels of printed hair with specified angles and heights.

Why 3D scans aren't copyrightable

Something that baffles laypeople about copyright is what is, and is not, copyrightable; US law and international treaties protect the creative part of copyright, but not the labor part of copyright: merely working hard ("the sweat of the brow") on something isn't enough to give rise to a new copyright, but even a trivial amount of creative work is. So copying out the phone book gives you no copyright, even if it takes you all year, doesn't make it copyrightable. But writing a single haiku does. Read the rest

Funeral parlor 3D prints new faces for disfigured corpses

Shanghai's Longhua Funeral Parlor now offers 3D printing of faces and other body parts to improve the appearance of the deceased during viewing.

"It is difficult for relatives to see incomplete faces or bodies of their loved ones when they attend memorial services, and makeup cannot always sufficiently repair them," Liu Fengming, an official with the Shanghai Funeral and Interment Service Center, said. From the Shanghai Daily:

After the explosion at Tianjin Port in August last year, the center sent experts to help repair the faces of firefighters killed in the blast.

The 3D-printing technology can also be used to make loved ones appear younger or better looking before they are interred, said Liu, who added that partial repair costs less than 10,000 yuan.

Dad teaches 10-year-old daughter how to design and cast a pewter ring

Designer Ivan Owens showed his daughter how to use Tinkercad to design a ring, print it in PLA plastic on a 3D printer, make a mold, and use the lost wax casting process to make a pewter butterfly ring.

My 10 year old daughter wanted to learn how to make her own metal ring by melting down the metal herself. …The video shows her learning to design and fabricate her own metal ring via sand casting using 3D design software, a 3D printer, scrap pewter, blowtorch, hammer, anvil, vise, drill & various other tools. I provided knowledge and supervision, but she drove the process. Through this process she learns that hazardous materials, such as molten metal, can be safely manipulated using the right equipment and techniques. She wanted to make a video of the process so that other kids could see all of the steps that go into making an everyday item like a ring.

Covert scan of museum's Nefertiti bust appears to be hoax

Last month I blogged about Nora Al-Badri and Jan Nikolai Nelles, a pair of artists who released a high-resolution scan of a looted Egyptian bust of Nefertiti in the collection of Berlin's Neues Museum, which has a reputation for refusing to make data from its collection (including 3D scans) public.

UPDATED Scanning artists de-loot stolen Egyptian treasure from a German museum

Update: All is not what it seems: it appears that the artists and the public were duped by a third party into passing off an illicitly obtained official scan as one that had been made by covert means.

Nora Al-Badri and Jan Nikolai Nelles, an Iraqi/German artistic duo, covertly scanned a famous looted Egyptian treasure, the Bust of Queen Nefertiti, from its contested perch in Berlin's Neues Museum. Read the rest
