Wall Street Journal, October 26, 2013 3-D Printing For All Shapeways, Cubify and i.materialise let everyone in on the 3-D printing revolution—no technical know-how required. By Matthew Kronsberg ACCORDING TO THE futurists, one day it will be commonplace to make just about anything—houses, chocolate bars, human tissue—using 3-D printers, those cutting-edge machines that can manufacture fully formed objects, as if by magic. Lose a button on your jacket? Need a new pair of glasses? No problem. Just print one up. At the moment, however, playing with a 3-D printer is not for the faint of heart. It helps to be familiar with computer modeling software. And although consumer-grade printers, like the MakerBot Replicator or 3D Systems Cube, are becoming more affordable, theyre best suited for hobbyists with plenty of time on their hands. After all, plain old 2-D inkjets are enough of a pain to maintain. Luckily, theres an easier way to explore this brave new world: online 3-D printing services. These websites are similar to photo services like Shutterfly, except instead of printing pictures that users upload, they print objects. The quality of their products can be a lot better than anything a home machine can produce, and they offer a broader choice of materials, including glazed ceramic, sandstone, brass, silver and titanium. Below, three ways to get your very own souvenir from the future. SHOP Certain sections of the 3-D printing sites Cubify ( cubify ), i.materialise ( i.materialise ) and Shapeways ( shapeways ) are like online bazaars of print-on-demand products. There, you can purchase objects that others have designed and uploaded. Think of it as Etsy without the yarn. The breadth of products is vast. Although there are a lot of over-engineered smartphone cases and Dr. Who jewelry to sift through, youll also find wares that are beautiful, practical and genuinely unique. On i.materialise, for example, designer Maaike van der Horns Bracelet Constructionist Sleek is an intricate, envelope-pushing design made of polished brass. Bathsheba Grossmans Ora Pendant, available from Shapeways, is a double-tetrahedron cast in metal—a piece that would be pretty much impossible to create using traditional jewelry-making techniques. Each designer sets the markup for his or her product, but starting prices tend to be reasonable. A plastic version of the Ora Pendant, for example, will set you back less than $7; in gold-plated brass, it costs $100. One Italian manufacturing company is using 3-D printing techniques to create art, satellites and even an electric motorcycle. Heres a look at how the technology works and why more companies are exploring it. The sites are also a good source for hard-to-find replacement parts. Search for replacement on Shapeways, and youll find connecting pegs for Thomas & Friends train sets, an array of camera-lens caps, even parts for a jet ski. Susan Parker, an engineer in London, created a replacement latch for her Panasonic breadmaker, thereby saving the appliance from the trash heap. In the 18 months since she uploaded her design, more than 200 people have ordered one, she said. CUSTOMIZE If you want to create your own 3-D printed product, but dont have any design chops, fear not. A number of sites let you tweak products exactly to your liking—or likeness. On i.materialise, you can make a lampshade with up to 140 characters of text embossed on the inside or exterior. On Shapeways, creating a 3-D printed ring is as simple as uploading a 2-D pattern, entering your ring size and selecting a material, like 22-karat-gold-plated brass. Bakers who want to move beyond the traditional cookie-cutter shapes should check out Cookie Caster ( cookiecaster ). This free online tool lets you draw a shape that you can have printed as a cookie cutter on Shapeways and most other 3-D printing services. And if you want to get really personal, let Cubify create a 6-inch-tall, full-color figurine with your face on it. Upload your photo to put your mug on an array of 3-D-printable characters (blushing bride, surfer dude or even a Formula 1 driver). DESIGN Virtually all 3-D-printed objects start with whats known as a CAD file (short for Computer-Aided Design), which is usually created using fairly complicated drafting software intended for architects, engineers and animators. But you dont have to get down and dirty with CAD. Plenty of apps make the process as simple as dragging and dropping. Tinkercad ( tinkercad ) a simple browser-based design tool, starts you off with a helpful tutorial. It has you connect simple shapes—like a sphere and cylinder—to make new ones. Want to create a rudimentary house? Just place a pyramid on top of a box. 123Design ( 123dapp ) is a free, beginner-friendly design app for browsers, iPads, Macs and PCs. Its most fun to use on a tablet—the iPads touchscreen makes designing in three dimensions feel more intuitive. If youre looking for the most basic option, try Cubify Draw for iOS. This dead-simple app lets you draw a single-line sketch with your finger and turn that into a 3-D-printed form with one tap. Magic, indeed.
