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

By David Nield Published August 30, 2014

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.”

Inside the quest to 3D print a perfectly palatable steak

3D printed steak

As people grow more concerned about the impacts of the meat industry both on the environment and the animals involved, fake meats have experienced a boom in popularity. Products like Beyond Burger and Impossible Pork, for example, have captured the attention of vegans and vegetarians across the globe for their astonishingly meat-like tastes and textures. But while ground meat substitutes have made big strides in recent years, plant based versions of more choice cuts aren’t yet on the menu. Whole cuts of meat are the next milestone for the fake meat business, and companies around the world are sprinting to replicate the most iconic cut of all: Steak.

And they’re doing it through 3D printing.
Steak: Nature’s meaty masterpiece
Even the tastiest ground beef arrives in your kitchen as a mass of reddish flesh pressed into plastic or wax paper. Next to that, a good steak is a Michelangelo fresco, with layers of muscle fiber and fat.

Father’s Day Gift Idea: These cheap 3D printers are on sale for less than $300

best 3d printer deals featured image

3D printing has become a lot more accessible these days than it had been in the past. Back then, you'd have to shell out as much as $1,000 for one. Today, however, there are plenty of budget 3D printers out that cost less than $300, such as the Monoprice Mini Delta, Longer Orange 10, and Comgrow Creality Ender 3. These are fantastic gifts for dad and if you order today they'll surely arrive before Father's Day.
Monoprice Mini Delta
-- $160, was $176

The incredible thing about the Monoprice Delta Mini, aside from the fact that it's one of the cheapest 3D printers on the market, is that it boasts a range of advanced features you typically won't find in a $160 3D printer. It has a sturdy, all-metal frame, a heated build plate that helps prevent warping, automatic bed leveling functionality, a maximum resolution of 50 microns, a full-color LCD screen, Wi-Fi connectivity, and compatibility with a wide range of materials. For something that costs less than a FitBit, all that stuff baked-in is pretty impressive. That's not to say the Monoprice Mini Delta is all that great. For starters, it's called Mini because its printing area is only 110 millimeters in diameter (4.3 inches), and 120 millimeters tall (4.7 inches), which definitely puts a limit on what objects you can print.

The 50-year old Silicon Valley lab that practically invented modern computing

50 years xerox parc alan kay

If I was a betting man, I’d wager that you’re reading this article from home. Why? Because, in the age of COVID-19, home is where just about everyone is these days. The fact that you’re reading this article in the way that you are, however, owes more than a passing debt to a Silicon Valley research laboratory called Xerox PARC, an abbreviation for Palo Alto Research Center.

Turning 50 years old this year, PARC changed the way that we use computers on a profound level. Far outstripping its remit as the research and development wing over the Xerox Corporation, it was to computing what Neils Bohr's institute at Copenhagen was for quantum physics in the 1920s or Motown Records was for soul music in the 1960s.
