Engineer builds a 3D-printed castle in his back garden

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.

The castle hasn’t been designed to house a king and queen, as you can tell from its small size. Instead, Rudenko wanted to use the structure as a proof-of-concept for his bespoke 3D printer and concrete extruding process. Now he has tested the technology, he plans to move on to creating a full-sized house for his next project. Anyone interesting in partnering in the scheme is encouraged to get in touch with Rudenko through the Total Kustom site.

“A new era of architecture is inevitable,” writes the designer on his blog, “and I’m excited to see where the next few years will lead in terms of construction and design. I have previously been sure I could print homes, but having finished the castle, I now have proof that the technology is ready.”

Many hybrids rank as most reliable of all vehicles, Consumer Reports finds
many hybrids rank as most reliable of all vehicles evs progress consumer reports cr tout cars 0224

For the U.S. auto industry, if not the global one, 2024 kicked off with media headlines celebrating the "renaissance" of hybrid vehicles. This came as many drivers embraced a practical, midway approach rather than completely abandoning gas-powered vehicles in favor of fully electric ones.

Now that the year is about to end, and the future of tax incentives supporting electric vehicle (EV) purchases is highly uncertain, it seems the hybrid renaissance still has many bright days ahead. Automakers have heard consumer demands and worked on improving the quality and reliability of hybrid vehicles, according to the Consumer Reports (CR) year-end survey.

Rivian tops owner satisfaction survey, ahead of BMW and Tesla
The front three-quarter view of a 2022 Rivian against a rocky backdrop.

Can the same vehicle brand sit both at the bottom of owner ratings in terms of reliability and at the top in terms of overall owner satisfaction? When that brand is Rivian, the answer is a resonant yes.

Rivian ranked number one in satisfaction for the second year in a row, with owners especially giving their R1S and R1T electric vehicle (EV) high marks in terms of comfort, speed, drivability, and ease of use, according to the latest Consumer Reports (CR) owner satisfaction survey.
