Rylan Grayston, a 28-year-old Canadian man with no formal training in engineering or computer science, has developed a successful 3D printer that could retail for about $100, according to a recent CBC News report.

Called the Peachy Printer, it runs with no microprocessors, but instead relies on audio technology. The software translates data from 3D models into an audio file, which is played to the Peachy Printer through a computer's headphone jack. The audio file controls a system of mirrors that reflect the laser, which creates the shape of the object. A more detailed explanation is available in the YouTube video below.
What's more impressive is that, in the video report for CBC News, Grayston shows a functional 3D printer made out of household items.
The project may go on to be a commercial success, having exceede $650,000 in funding against a $50,000 goal on its Kickstarter campaign. In total, Grayston has raised $720,000 in money via crowdsourcing to date, according to CBC News.
Of course, it wouldn't have been as popular if it didn't work. One 3D printing expert told CBC News that the Peachy Printer "completely changes the game."
"To be able to do it for a hundred bucks and basically with stuff you can find around your house, that's the thing that changes everything," David Gerhard, a computer science professor at the University of Regina, told CBC News.
Indeed, the Peachy Printer is the biggest at-home 3D printing breakthrough since The Liberator, the 3D-printed pistol that fired its first shot in May and whose design files were seized by the U.S. government just days later.
