3d Battery Printer

I am upgrading my prusai3 to a massive build volume during which I will also be adding peristaltic pumps, for printing batteries

Batteries are currently made in factories halfway around the world. Distributed manufacturing is the future so we must discover a method for making batteries locally in whatever form factor is desired.

Alot of custom projects could use custom batteries, but they are simply not available.

By the end of this project I aim to be able to set dimensions in software and click the print button, a few hours later I should have a brand new battery or ultra-capacitor.

I am aiming to have 3 part systems with all my batteries, and ultracapacitors to allow them to be sprayed, painted, or printed in layers and create a completely modular battery system.

This will be very helpful to a large number of DIY'ers.

The system will consist of a x-axis that houses 3 peristaltic pumps. These will pump liquid out of pipettes and drop cast an anode, cathode, and seperators/electrolyte onto a heated build plate where they can be built up in series or parallel to print a battery.

The software is all pretty much completed and I believe I will be able to use slic3r and RepRapPro host to do "multicolored" prints with each of my materials.

The difficulty lies in engineering the x-axis, affording materials for this build and engineering a much larger printer. For the heated bed will be usable in different 3d printing applications it is its own project.

    I think the azteeg x3 pro will be the best option I will need to add a fourth extruder for placing an electric and ionic insulating material.

    I picked up a bottle of CO2 and argon today from my jerb I might need to run straight argon in this system for any lithium or potassium hydroxide supercapacitors as they absorb CO2.

    There is always that option or going with a delta morphology inside a composite reinforced cement tube. Then pulling a vacuum on the whole thing to reduce vapor pressure and reduce drying times.

Can you talk more about the chemistry of the batteries you wish to print? What would be example steps using this system that would lead to a working battery?

  Are you sure? yes | no

Look at the rest of my projects, everything from new paradigm super capacitors to potassium sulfur silica batteries.

The title sounds more like the 3d printer is powered by batteries, instead of 3d printing them. Interesting project :)

Thanks, I changed it maybe it is better now.
