You may have seen this 3D Printed Castle on the news:
The story has been picked up by NBC, CNET, Gizmodo, Independant in the uk, and others. 3DPrint.com broke the story and has the best pictures and details:
As castles go, it’s not huge; more like “Tiny Home” size. To give you a reference, an adult can walk through the arch of the front door. But there are people already asking if they can buy it!
And it’s actually the first building 3D printed in place; the 10 homes in China which were all the news a month ago where actually assembled by humans in one day after the parts were printed separately over a much longer time.
How long does it take to print a castle? 3 to 4 days of continuous operation. Since this was the first one, that was spread over several weeks as tweaks and changes were made to the monster 3D printer which you can see in this video during testing in the makers (Andrey Rudenko) 2 car garage. Indoor development was necessary because of the frigid cold winters in his Minnesota home.
Driven by San Diego trons
What you may not know is that the drive electronics are open source, and supplied by a San Diego (well… Escondido) local. James Newton of MassMind.org provided the stepper motor drivers that make this printer move:
Andrey made extensive use of open source technology: “I was lucky to get lots of invaluable input and support from individuals from the RepRap community. Specifically, I am eternally grateful to James Newton for his constant support with the drivers.” The motion controller is a standard, fully open source, RAMPS / Arduino running Marlin firmware and the narrow step pulse was incompatible with other drivers. The MassMind THB6064AH driver is responsive enough to use with the fast acting 3D printer controller, but powerful enough to run the NEMA 34 required to move this monster printer.
The PCB for the driver, designed by Luc Degrande of Belgium, combined with carefully selected components, reliably provides 4 Amps at 50 Volts or 200 WATTS of power, with up to 128 microstepping for smooth motion. And because it is built from a $35 kit, if anything does go wrong, repair is cheap: Just replace the $10 driver chip.
