Questions you would ask if someone said they had a 3D printer for professional multi-layer PCBs?

We're developing a 3D printer for professional multi-layer PCBs with 3-4 Mil. traces. What concerns or questions would you have about such a system?

Are we talking a professional device that takes something like the Squink/Voltare/EX1 projects on Kickstarter and delivers something that could be confidently used commerically? Would it be strictly a prototyping tool or would it also be suited to lo

Firstly thank you for your time and consideration. Yes a professional device along the lines of the products seen on kickstarter. A system to be used by labs, R&D, product development centers etc. The difference from current offerings being resistivi

To get real conductivity in your traces you will need to remelt your copper or silver tracks. This means 850oC. The other method is plating at low temps, or etching. Epoxies like all carbon based compounds vaporize at 400oC. Next problem epoxy fibre

...Unless you could dispense a fine glassfibre mesh in much the same way a 3D printer extrudes plastic filament and then spray epoxy over the top. It would be remiss to 2nd guess what compounds physical chemists can come up with for such a project. E

When I and some friends worked on this project we were aiming for an hour turnaround time. But as the years of development went on we upped the board specification considerably. Also the world changed under out feet as we could get commercial protot

Thanks Sarason, You are right that chemists and physicists now have some new tricks. Using nano-chemistry the physical properties of the materials change. The melting temperature of our nano-particle silver is below 150C. The insulator is also a nano

When discussing this with the customer he said that his vendor recommended a hard gold plating finish on the board due to the BGA. I said "hard gold"??? And he said yes, hard gold. Turns out the boards were plated with hard gold, not ENIG. Thank
