I first started reading about 3D printing last year, although the machines have been sold commercially since 2010. "Printing" isn't the right word—they basically build entire objects. I know it sounds like something out of the future, but it is happening, and it is a technological marvel.
The 3D printers are being used to make, among other things, car parts, dental parts, toys, jewelry, food and prosthetic limbs. Researchers are working on using them to produce muscle tissue, skin, kidneys, cartilage and bones. Really, the possibilities are infinite. Here is an excellent Smithsonian Magazine article on the topic, and a you've-gotta-see-it-to-believe-it video of a wrench made on a 3D printer:
You need a special computer program to create the virtual blueprints, whether it's computer aided design (CAD) or animation modeling software. The program divides the object into digital cross-sections, and you zap the design to a 3D printer which builds layer upon layer to form an object. Mostly, plastic is being used, but so is rubber, paper and metal. People can download designs—or request them—at sites including Shapeways and Sculpteo.
Amazon sells desktop 3D printers. The UP! Mini 3D Desktop Printer ($922.46) builds objects to a max of 4.75 x 4.75 4.75. Users report making mazes, compression springs and decorative objects like a snowflake...and spider. Costs are coming down; Amazon has one not yet available for $500, XYZPrinting Da Vinci (above).

The boy in the photo above, Matthew, was born limb different. Although he hadn't shown an interest in a prosthetic hand, the cost is prohibitive, $18,000 and up. His mother, Jennifer, showed a picture of a Robohand created on a 3-printer to a 16-year-old family friend. He downloaded a computer file for it from Thingiverse. He printed it out on the 3-D printer at their local library in Johnson County, Kansas. And voila, Matthew had a prosthetic hand.
That's what's so genius about 3D printing and its possibilities for those with disabilities: People will be able to print out customized designs to best fit their bodies and needs. One man recently made himself a mini wheelchair ramp he totes around, so he can glide over steps. In 2012, as reported by Fast Company, Enabled By Design—a British nonprofit that helps people live independently—held a designathon that featured 3D products. One guy invented a water-heating device that could be manipulated using the upper arms only, no hand motion required.
Printers could someday make customized walkers, gait trainers and foot braces at reasonable costs; another major benefit of 3D printing is that it will make products more accessible to people in all income ranges. A 3D printer could produce hearing and visual aids (recently, a design student in India created 3D puzzles to help children learn braille); adaptive toys and equipment, specialized seating for homes and cars; even swings (adaptive ones are often such a rip-off). Speaking of which, they'll also spew out those darn overpriced adaptive utensils. Excuse me, price-gouging company that charges $30 bucks for a spoon, I'll just print my own! (And DIY-ing is key—one site is already selling 3D printed adaptive teacups for $99. Sigh.)
This is a major trend. One sign: South by Southwest's Interactive Conference, which kicks off this Friday, is running a session on 3D Printing for People with Disabilities. If the techno-peeps of this world are psyched about it, all the better for our kids.
I'm definitely mentioning this to Max's school, and our local library. I could see purchasing one in a year or so, when the technology has gotten even better, and making utensils for Max. I can see crowdsourcing designs for him—he could use a better tool for holding a pen and pencil, for one. But I'd have to hide the machine from Max, or he would make it my life's work to crank out all things Lightning McQueen.

Devices for children made via 3D printing could grow with them, another cost-saver. Seersucker magazine tells of a girl born with a genetic condition that causes her joints and muscles to stiffen, leaving her arms inflexible and underdeveloped. Developers created a lightweight, plastic robotic exoskeleton through a 3D printer, and they will make new parts as she grows. Here, watch:
