3D printing enthusiast Andrey Rudenko has just put the finishing touches to a project he can be proud of: a custom-made castle erected in his back garden. The contractor from Minnesota has been working on the structure for the past two years, and while there’s not quite enough room for a court and stables it’s a remarkable feat of engineering.
Rudenko wants to move on to a full-sized house next through his Total Kustom firm.
The castle measures 10 feet by 16 feet (3m by 4.9m) and stands 12 feet (3.7m high). One of the biggest challenges Rudenko faced was finding the right liquid concrete mix: “Although cement has existed for thousands of years, it hasn’t been common to use cement mixes for low-speed precise extrusion,” he told CNET. “It took a lot of research and experimenting to come up with the proper mix. So the recipe is my own with common materials and some additives.”
We might be some way off from having a 3D printer installed in every home, but barely a week goes by without some new demonstration of the technology’s potential — from saxophones to ice cream, there’s no real limit to what 3D printing can eventually do. … (Read more)
