If you are interested in the 3D Metal Printer project, please try to support it in Patreon. 

Since January I'm spending more time trying to get funds, publishing the project in different sites, but is very hard to get some funding.

The goal is to make 3D Metal Printing more affordable to the general public, hospitals, small institutions, organizations and companies around the world. Specifically for developing and low income countries. This project fills a gap that no open hardware successfully fills.

Here is the Patreon site to support the project:

I have been working on the new electron gun for the last months. I have designed and built the new version with many improvements.

I achieved a 0.1mm spot size in the center of the working area. This is very good news for printing fine details in metal parts.

This 0.1mm focus test was very useful to understand the need for a stable HV power supply. With my HV power supply, small changes in the mains AC input translate to changes in the HV output and focus spot size.

So is a good idea to test a commercial HV power supply or add some kind of feedback control to the Cockcroft Walton multiplier.

This was one of the most difficult technical parts. There are still many challenges to solve, but this was a big step.

Please remember to support me to continue working on this project. I'm waiting some financial support to release the designs and schematics. Many thanks for your help!
