Watch the engineering challenges overcome in turning a 3D printer into a tattoo machine

Technological breakthroughs are spurring innovations in the industry

What if you could see your tattoos before they’re embedded in your skin? Or take a virtual visit into a local studio to work out your nerves over a first tattoo? The industry is anticipating some big technological changes, from 3D designs to sci-fi upgrades to more precise tattoo guns.

'Magic ink' is redefining the tattoo

One University of Colorado professor has developed an ink that can be "turned on" with exposure to UV light, and "turned off" with sunlight. While the ink could help those who want to hide their body art from family members or coworkers, there are potential uses for medical procedures.

Chip-based 3D printers can be pocket-sized and involve no moving parts

Researchers have demonstrated a proof-of-concept version of a chip-based 3D printer that emits visible light onto light-sensitive resin to construct solid shapes. The technology may provide a portable, low-cost solution for future, small-scale fabrication needs.

Samuel O’Reilly patented the tattoo gun in 1891

Before the tattoo gun's invention, recipients sweated while artists slowly tapped or sliced designs into their flesh. The tattoo gun changed the field, helping artists ink clients’ skin at incredible speeds. Inventor Samuel O’Reilly applied the basic idea of an electric pen invented by Thomas Edison to his tattoo gun.

Thingiverse is a massive free library of 3D-printable designs

The site—which was launched in 2008 by 3D-printer manufacturer MakerBot—hosts more than 2 million user-generated design files to build everything from prosthetic hands to replacement dishwasher parts (or the "Golden Snitch" from "Harry Potter). The community behind it rapidly designed and shared files for face shields and ventilator components amid the COVID-19 pandemic.

The immune system fights tattoos

Our skin is a fascinating organ that wants nothing more than to protect our bodies from the outside world. Tattoos penetrate that protective wall to inject ink directly into the sensitive, immunologically rich layer of skin known as the dermis.

View a timeline of 3D printing technology through 2019

The first working 3D printing device was invented in 1983 and utilized stereolithography, a process in which a laser triggers a chemical reaction that hardens liquid resin. Powder-based laser sintering technology was patented in 1987, with metal-based powders first being used for 3D printing in 1997.

Prosthetics and orthotics have been 3D printed to improve the lives of animals

Shells for hermit crabs, wheelchairs for guinea pigs and dogs, and horseshoes for improved running performance have been created using 3D printers. Other artificial body parts made using this technology include a jaw for a loggerhead turtle, a beak for a toucan, and a tail for an American alligator.

Microgravity environments improve the success of 3D bioprinting

Gravity can cause gaps, such as those in the chambers of a 3D-printed heart, to collapse before stem cells, hydrogels, and biochemicals bind together during the bioprinting process. Rather than Earth's surface, some bioprinting is done on the International Space Station, where defective organs are also printed to test treatment methods.

Rune Elmqvist forwent practicing medicine to invent the first inkjet printer

The Mingograph recorded real-time physiological signals from a patient's electrocardiogram, helping doctors diagnose heart and brain conditions. Eight years later, in 1958, Elmqvist worked with cardiac surgeon Åke Senning to develop the first fully implantable pacemaker.

Watch the iterative process of successfully printing a slice of vegan cheesecake

3D printing food requires integrating ingredients with a variety of properties, which may not all resist the physical stress of stacking. This means successful 3D printing of food may require rethinking how ingredients are layered and modifying ratios of each, potentially sacrificing taste for structural integrity.

View a gallery of 3D printed clothing

Many 3D printed garments represent wearable art where technology meets couture. Despite their appearances on runways since Iris van Herpen's pioneering top at Amsterdam Fashion Week in 2010, mainstream adoption has been limited due to high costs and reduced comfort when compared to fabric-based apparel.

The man who turned his leg into a hotspot

Biohacker Michael Laufer recently had a 512GB drive implanted in his leg, which can store data, stream music or movies, and power a hot spot and mesh network. It's called the PegLeg, and WIRED's Daniel Oberhaus spoke with Laufer about the device and the field of biohacking.

Laser-etched electric charges guide toner during laser printing

When sending a print job, the file data generates an image that a laser maps positively charged regions onto a drum separately for each color toner. Once the negatively charged toner is applied where it was electrically attracted, heat and pressure fuse it onto the paper.

Components of the 'ghost gun' allegedly used by Luigi Mangione were 3D printed

Although some "ghost guns" are firearms whose serial numbers have been removed, many others are built from pieces that can be printed using readily available online data files. Federal laws and some states do not prohibit the construction of these DIY firearms for personal use.

Efforts to build touch-enabled machines highlight the complexity of human touch

The challenges that engineers are facing as they try to reproduce a human's ability to touch and also give robots the ability to interpret that kind of sensory flow are furthering our understanding of the myriad intricacies of human touch—and the challenges in emulating it.

As a child, Twain worked as a 'printer's devil'

Twain’s father died in 1847, forcing the 12-year-old Twain to leave school to earn money for the family. He took up work in a print shop as a “printer’s devil,” or an apprentice. He became fascinated with the technology, an experience he’d pursue further when he became a journalist several years later.
