A mechanical engineer based in North Dakota and known online as PizzAndy has developed a prototype 3D printer that replaces conventional resistive bed heating with Bitcoin mining ASIC chips. Showcased on the Home Mining Podcast, the system embeds mining hardware beneath the print surface so that hashing activity generates heat while simultaneously mining Bitcoin. Development is published under the name Proof of Print.
PizzAndy said the concept emerged after observing that ASIC operating temperatures align with common bed requirements for materials such as PCTG, which typically prints between 75°C and 80°C. The current prototype integrates four BM1362 ASIC chips mounted under a bed measuring approximately 110 by 110 millimeters. During active printing at roughly 75°C, the system averages a
