Are we finally close to fabbing real PCBs at home?
In this episode, Seve (tscircuit) and Matt (atopile) go deep into the state of DIY PCB fabrication: why it feels like the early days of 3D printing, what's still holding it back, and what could push it over the edge.
We talk lasers, vias, copper, tariffs, and some surprising hacks people use to prototype faster without sending things to China.
What You’ll Learn Today:
How fiber lasers are being used to blast copper off PCBs
Why vias are still the bottleneck for DIY PCB prototyping
What a $200K laser ablation machine actually does
How one engineer claims to make PCBs with no chemicals at all
Whether DIY sintered copper vias might actually work
How U.S. tariffs sparked a wave of fake “local” PCB fabs
Why 3D printing and PCB fab might follow the same path
What still needs to happen before in-house PCB manufacturing is truly usable
Whether you're building hardware, designing boards, or just wondering what’s next for fast prototyping, this is one of our most technical and fun episodes yet.
