AN ALMOST REAL THING

“123D Catch” is a free app from Autodesk that lets you use the iPad 2 or iPad 3 to create 3D renderings of objects snapped with the tablet’s

camera.

You have to send the 3D code generated by the app to a 3D printer or laser cutter. There are a number of services that provide that and costs vary, but we thought they were reasonable. Replicate your dog, your sofa, your mother-in-law. There’s also a desktop version at 123dapp.com/catch
