Man Constructs 3D Printed Concrete Castle

Man Constructs 3D Printed Concrete Castle
Minnesotan contractor Andrey Rudenko is now the king of his castle; his 3D-printed concrete castle, that is. After completing a journey that took more than two years, Rudenko developed a customized 3D printer to extrude concrete and build a castle that he had designed himself. The entire structure is approximately 3 meters by 5 meters, which really makes it an amazing backyard fort rather than an actual livable structure. Extruding concrete to create 3D-printed buildings isn’t entirely novel. It has been proposed to quickly create inexpensive housing in poverty-stricken areas and even to build infrastructure on Mars before the arrival of astronauts. However, those buildings were designed to be fairly simple and lacked architectural details. Image credit: Andrey Rudenko, Total Kustom As a machine capable of extruding concrete wasn’t commercially available, Rudenko had to develop his own. The concrete was extruded in layers that were 3 cm wide and 1 cm thick.

Multifunctional 3d printing delta robot ZeGo launching on Monday April 26, 2014 The ongoing race to build the cheapest, most versatile 3D printer continues with the impending launch of the ZeGo bot, an opensource multifunctional delta linear robot. ZeGo Robotics, a Pittsburgh, Pennsylvania based startup, is set to launch ZeGo bot on crowdfunding website Indiegogo on Monday. Densely Populated Countries Could Find Food Independence With Vertical Floating Farms Singapore has roughly 5.4 million people crammed into 716 square kilometers (276 square miles), making it the most densely populated country in the world. This country—whose area is less than a quarter of that of Rhode Island—does not have enough room for agriculture and thus imports over 90% of its food from other countries all over the world. Not only does this add considerable cost to food prices for Singaporeans, but the reliance on others might become problematic in the future if availability is low. While Singapore might not have much land to spare to grow food, it is surrounded by plenty of water. Barcelona-based architect Javier Ponce of JAPA Architects (now under the name of Forward Thinking Architecture) has designed what he calls Floating Responsive Agriculture (FRA).

Cheap DIY 3D Scanning… or not This article did not turn out like I wanted. I intended for this to be a How-To guide for cheap 3D scanning, filled with pictures and screenshots. It’s an incredibly useful concept, turning a physical object into a digital one. There are many applications for such an ability, from customizing an object to repairing or duplicating it. Unfortunately, cheap 3D scanning is currently, for me at least, rather impractical. Let me be clear, I don’t want to discourage anyone from doing their own DIY 3D scanning; quite the opposite, I hope that you do so that the software more quickly develops.

3D printing with a delta robot that seems to simplify the concept This 3d printing delta robot really seems to solve a lot of the hurdles faced by previous offerings. With other delta printers we’ve looked at the motor control of the three arms is usually a it complicated. On this build the motors can just be seen in this image at each corner under the build platform. Each motor has a belt that loops from the bottom to the top for the machine, driving an arm along two precision rods. It’s also interesting to note that the printer head doesn’t have a motor mounted on it for feeding the filament. Instead, the motor is mounted remotely.

voxeljet Concept: The First Continuous 3D Printer If there ever was a major leap in the evolution of the 3D printer, the voxeljet Concept is the benchmark machine to follow. In the explosive arena of start-ups that produce innovative 3D-printers, voxeljet has decided to challenge and change the direction of how 3D printers work. Taking a look at three specific factors that set this process apart from others on the market, it becomes quite clear just how revolutionary this concept is. The ability to have a continuous supply of consumables delivered to the machines as it is making a model. This is made possible because the bed of consumables sits above where the models are actually made. The printhead sits in an area that it tilted at about a 35 degree angle with a printhead resolution of 600 DPI.

Futuristic Chinese Megastructure Would Include Soaring Towers, Massive Skyways, Urban Farms Many of the world’s cities are hundreds, even thousands of years old. They evolved from the bottom up as populations changed and demanded change. A new road here, new building there. The result is striking and wild—a kind of physical history. But what if you could start New York or London from scratch? To see skylines of the future—look east. DIY 3D scanner Cool. Splinescan used to have something like that as well, sans flash. I'm not sure about the technical details, but ?javascript? tracked the mouse and the image rotated. It was only for one scan, and I think it was hand-rolled, but I think Andrew Lewis could write a python script to do it in an evening.

Plastics that can be recycled for 3D printing — Perpetual Plastic Project Okay, so we're heading towards the 2 year anniversary of Perpetual Plastic Project. By now we have done over 40 events all over Europe to show people the possibilities of 3D printing with plastic waste. But what plastic waste is suitable for the PPP process of recycling and 3D printing?

Student Develops Inexpensive Solar Lens To Purify Polluted Water Deshawn Henry, a Civil Engineering sophomore at the University of Buffalo, spent his summer developing a solar lens using inexpensive supplies from a hardware store that can clean 99.9% of pathogens in a liter of water in about an hour. The research project is practical and inexpensive, with the potential to be widely implemented and save lives. Over one billion people around the world lack consistent access to clean water, leading to the death of a child under the age of 5 every single minute. Many water treatment options are expensive. The device itself has a rather humble appearance, with a six-foot-tall frame of 2x4s topped with a lens constructed of plastic sheeting and water, which focuses down onto a treatment container for the water.
