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. 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. Unfortunately, his castle isn’t for sale. Read this next: Direct Brain-To-Brain Communication Used in Humans

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. After the break you can catch a clip of the team showing off the speed and dexterity of the delta bot, followed by a printing demo. [Thanks Kyle]

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. He may be open to approaches from people who are up for coding it or who want to play around in the splinescan source to see how things work, dunno. Once he hits a major release, I expect he may open up to co-developers who can add sexy/important features like David-scan has. I reallly want to install things like the flash thing, only without the server imploading. I'm lining up a test server to install a virgin mediawiki and phorum install on in order to test out stuff like this without rolling out unknown code on a primary server. I think it will be nice to support patch fuctionality, so that users can upload 'patches' to Darwin, Mendel, post-Mendel (Eiffel?) Patches would be clearly and politely labeled as such, and we'd manually check them into the master release after user/dev testing.
