Inventor PizzAndy unveils a 6 TH/s Bitcoin miner that uses waste heat to dry 3D printing filament, joining his lineup of crypto-mining 3D printing devices.
An inventor has unveiled a novel 3D printing accessory that combines cryptocurrency mining with filament drying - a filament dryer that mines Bitcoin while using the waste heat to keep filament dry.
Bitcoin Mining Meets 3D Printing
PizzAndy from Proof Of Print, the same inventor behind the 3D printer that mines Bitcoin, has created another prototype that integrates crypto mining with 3D printing functionality. The new device is a filament dryer capable of 6 TH/s at 140W that uses the waste heat from Bitcoin mining ASICs to maintain optimal filament temperature.
This prototype represents an innovative approach to solving two problems simultaneously: keeping 3D printing filament dry and generating cryptocurrency. The device maintains filament at a predefined controlled temperature, preventing it from absorbing moisture from the air - a common issue that can cause popping, stringing, and bubbling during the printing process.
The Technology Behind the Innovation
The underlying technology appears to be similar to PizzAndy's previous creation - a 3D printer that uses the printer bed as a heatsink for throttled BTC mining ASICs. In that earlier prototype, the printer could manage 500 GH/s when the bed was at 75°C. The new filament dryer represents a significant scaling up of this concept, achieving 6 TH/s at just 140W.
By using the waste heat from mining operations for filament drying, the device effectively repurposes energy that would otherwise be lost, creating a more efficient system. This approach eliminates the need for separate heating elements while simultaneously generating Bitcoin.
Why Filament Drying Matters
Filament dryers are valuable tools for both professional 3D printing operations and hobbyists. Moisture in filament can cause numerous printing problems, including weak interlayer bonding and poor surface finish on printed objects. A dedicated filament dryer provides more precise temperature control than alternative methods like using a kitchen oven, which also has the added benefit of avoiding domestic disputes about using household appliances for 3D printing purposes.
Expanding the Crypto-3D Printing Ecosystem
The filament dryer joins PizzAndy's growing lineup of Bitcoin-mining 3D printing devices, which includes the original 3D printer with integrated Bitcoin mining capabilities. These innovations represent an interesting intersection of cryptocurrency technology and additive manufacturing, potentially offering hobbyists and professionals ways to offset equipment costs through crypto mining while maintaining optimal printing conditions.
The development suggests ongoing refinement and scaling of the technology, with the new dryer achieving significantly higher hash rates than the original printer prototype. Whether these devices will move beyond prototype status to become commercially available products remains to be seen, but they demonstrate creative approaches to combining different technologies for enhanced functionality.
