A glowing, 3D printed rose that "blooms" when you touch its petals

Daren Schwenke's 3D printed blooming rose embeds a capacitive touch sensor -- a magnetic wire -- in one of the leaves, which trips an Arduino-controlled actuator that changes the rose's lighting and causes the petals -- 3D printed and then shaped over a hot chandelier bulb -- to splay open or fold closed.

Acoustic meta-material: a shape that reflects sound but passes light and air

A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.

Make: a 3D printed replica of the shrine from Deities and Demigods, sized for D&D minis

Deities and Demigods is a storied resource book from the first edition of Advanced Dungeons and Dragons: between being copyright trolled by false claims of infringement on the Lovecraft estate (and a more valid copyright claim over the use of Elric of Melnibon mythos), and the general uselessness of gods and demigods to the vast majority of D&D campaigns, and the book's usefulness to nutjobs who claimed that D&D was a trojan horse for occult indoctrination, Deities and Demigods is a title whose reputation redounds even today.

New 3D printed corneas could save millions of people's vision

Researchers have spent decades exploring methods to 3D print organs for transplant but progress is slow due to the complex structure of, say, a kidney or pancreas. Precise Bio, a startup founded by scientists from Wake Forest Institute for Regenerative Medicine, claim that the first real success will come from 3D-printed corneas. They've already conducted animal studies and are building a roadmap toward human trials. From IEEE Spectrum:

Corneas could be the first mainstream application of bioprinting, (Precise Bio CEO Aryeh) Batt says, in part because they have a layered structure that’s a good match for the technology. Each layer consists of different types of cells and fibers, which the printer could lay down in sequence, and these layers don’t contain blood vessels or nerves. What’s more, putting a new kind of transplant in the eye is inherently safer than implanting one deep in the body, since physicians could easily check for signs of trouble and could remove the tissue if anything seemed wrong.

There’s certainly a need for more corneas in the world, says Kevin Corcoran, president and CEO of the Eye Bank Association of America. In 2017, his members supplied nearly 51,000 transplantable corneas to patients in the United States, and also sent more than 26,000 abroad. Internationally, “there is a tremendous amount of unmet demand,” he says. “It’s estimated that 10 million people suffer from corneal blindness globally, primarily because they lack access to effective and affordable treatment.”

Part of Precise Bio’s proprietary approach is its printer, which uses a technique called laser-induced forward transfer to propel droplets of bioinks onto a surface.

Security researchers identify "fingerprints" in 3D printed objects that can be used to trace their manufacturing

In PrinTracker: Fingerprinting 3D Printers using Commodity Scanners (Scihub mirror), a paper to be presented at the ACM SIGSAC Conference on Computer and Communications Security conference in Toronto this month, a group of U Buffalo and Northeastern researchers present a model for uniquely identifying which 3D printer produced a given manufactured object, which may allow for forensic investigators to associate counterfeit goods, illegal guns, and other printed objects with the device that manufactured them.

3D-printed gun promoter arrested in Taiwan, returned to US, and bailed on sex charge

Charged with paying a 16-year-old girl for sex at a hotel in Austin, Texas, Cody Wilson was bailed Sunday and is a free man again—at least for now. The BBC reports that Wilson, famous for promoting 3D-printed gun plans, was arrested by Taipei police and returned to the US over the weekend. KHOU 11 filmed him leaving jail and hopping into a cab.

Wilson’s attorney Samy Khalil of Gerger, Khalil & Hennessy released a statement late Sunday evening.

“We are glad that Cody is back in Texas again where we can work with him on his case. That’s our focus right now, representing our client and preparing his defense.”

It’s been a long journey back for the accused 3D-printed gun designer.

Authorities say the 30-year-old flew out to Taiwan after a friend told him he was being investigated for allegedly paying $500 for to have sex with a 16-year-old girl he contacted online.

Surveillance video shows Wilson checking in to a Taipei hotel Thursday. That’s where police finally arrested him on Friday.
