Productive Heat.
Bitcoin Rewards.
Replace conventional 3D printing heaters with Bitcoin-mining ASIC heaters. The heat your equipment already requires can now generate Bitcoin rewards, offsetting operating costs without changing your workflow.
Product Today. Platform Tomorrow.
🟢 Near-Term Product Candidate
Mining Filament Dryer
Built to bring productive heat reuse to market first. A standalone filament dryer that keeps your material dry while the ASIC chips maintain temperature and generate Bitcoin. Continuous operation makes this the ideal entry point for commercial deployment.
What It Proves: Bitcoin mining heat can perform useful filament drying work in a standalone product.
Development Stage: Product Development
- Power draw140W
- Hashrate6 TH/s
- Spool capacity2 spools
- StatusWorking prototype
🔵 Future Platform Technology
Mining Printer
Demonstrates the long-term vision: integrating Bitcoin-mining hardware directly into additive manufacturing systems. This prototype proves that ASICs can replace conventional bed heaters while maintaining precise thermal control and print quality.
What It Proves: ASICs can replace conventional bed heaters while maintaining controlled print temperatures.
Development Stage: Technology Validation
- Bed temperature75°C demonstrated
- Thermal controlKlipper integrated
- Mining chips4 × BM1362AK
- StatusWorking prototype
Why the filament dryer first? The mining filament dryer is Proof Of Print's commercial entry point because it uses steady, low-temperature heat, has a simple workflow, and can operate independently from the printer. This path allows us to reach market sooner, validate the thermal and mining architecture in production, and build the foundation for the broader printer platform.

Why It Works
Productive Heating
ASIC mining chips replace conventional heating elements. Every watt spent on required process heat simultaneously generates Bitcoin rewards. No wasted energy.
No Workflow Changes
A drop-in replacement for existing heaters. Your printer operates exactly as before: same temperatures, same print quality. Bitcoin is a byproduct, not a compromise.
Industrial Economics
Print farms already run heat-producing equipment for long hours. Proof Of Print turns required process heat into a Bitcoin reward layer, helping offset energy costs without changing the core operation.
Who It's For
Print Farms
Machines running around the clock generate consistent Bitcoin rewards. At scale, mining income meaningfully offsets the electricity bill, turning an operating cost into a revenue stream.
Manufacturing Operations
Industrial additive manufacturing requires reliable, precise heat. Our modular tile system delivers zoned temperature control across large bed areas while generating Bitcoin in parallel.
Universities & Research Labs
Research institutions running additive manufacturing equipment can offset operating costs while contributing to Bitcoin's decentralized network. A practical use case for energy that would otherwise go to waste.
Hobbyists & Enthusiasts
Makers, Bitcoiners, and early adopters who enjoy experimenting with innovative hardware and exploring new ways to combine manufacturing, computing, and energy systems.
