💡3D printer that can mine Bitcoin uses excess heat for temperature control

PizzAndy created a 3D printing prototype that mines Bitcoin. The hybrid device is based on an open-source 3D printer design with a custom bed that is heat-controlled by throttling the Bitcoin mining ASICs attached to it. The printer bed is basically a heatsink.

The compact prototype is capable of a humble 500 GH/s when the bed is at 75 °C, says PizzAndy, but there are already plans for scaling and a tile-based model using Intel ASICs targeting at least 10 TH/s.

PizzAndy says the thought initially popped into his head 5 years ago, when he was heating his basement workspace (in the cold months) to help his 3D printers work better. The 3D printer/BTC enthusiast thought it would be “a cool thing” to mix these two technologies, but wasn’t sure about its commercial value. Since that time, he has become convinced that a commercial product is worthwhile.
