The Problem: The last major barrier to consumer 2-layer boards is the Via Problem — connecting top and bottom copper layers currently requires dangerous wet-chemical plating processes that are completely unsuitable for home or school environments. Our solution: a novel CNC toolhead that uses plasma sputtering to directly deposit copper inside vias and traces. This dry process eliminates toxic waste, minimizes consumables, and unlocks precise, automated copper deposition — essentially letting users "spray" copper where it's needed at the atomic level. The Impact: With this tool, anyone can fabricate complete PCBs safely from their desk, same-day, without a factory. We believe this is the keystone to a new era of localized hardware production, from school labs to orbit. The Ask: We're raising funding to prototype the first generation plasma toolhead, validate key physics, and position Suneater Labs as the leader in desktop electronics manufacturing infrastructure. --- ``` #FFCC66 - gold - sun #1f0034 - purple - void ``` ![[01.jpg]] ![[Pasted image 20250510101828.png]] ![[Pasted image 20250510101835.png]] ![[Pasted image 20250510101841.png]] ![[Pasted image 20250510101847.png]] ### People - https://x.com/jwt0625 - https://x.com/Chrismholt - https://x.com/liminalsunset_ - https://x.com/Xaraphim - https://x.com/kylecompute - https://x.com/spin_resonant - https://x.com/XanaIndustries - https://x.com/0xJirachi - https://x.com/parthingle_x - https://x.com/timbotdotnet - https://x.com/oldestasian - https://x.com/alignment_lab - https://x.com/BcuzCombinator - https://x.com/byte_thrasher - https://x.com/SAWTinspace - https://x.com/servomechanica - https://x.com/0xnullcline - https://x.com/H2Colby - https://x.com/_imdawon - https://x.com/codyaims - https://x.com/Memorized - https://x.com/neonplaidpants - https://x.com/lukebayes - https://x.com/boxcardavid
