MCOR on Golem

MCOR chief Conor MacCormack was interviewed by German IT news site Golem, in which he takes us on a detailed technical tour of their amazing paper-based 3D printer. Here’s the highlights:
  • Up to 3 full reams of common A4 paper is accepted by the machine
  • Sheets are fed, one-by-one, into the build chamber (or should we say cutting chamber?)
  • The machine cuts with a microscopic tungsten-carbide blade that is adjustable on the micron scale to account for different paper thicknesses
  • The cutter is so fine it is able to slice a page without disturbing the sheet beneath
  • The chamber is 1500mm high, and that’s the maximum size of a build
  • Adhesive (that sticks the layers together) is applied selectively to avoid waste
  • Completed builds emerge as a full ream of paper; you must peel off the waste paper by hand to reveal the final object
  • Proprietary software was shown, and it appears to offer similar features to other 3D printing control systems
You might think printing an object in this way produces a lot of waste. Well, it does – but remember, paper is recyclable, and it’s perhaps the least expensive print material we’ve seen.
