Social Darwinism

Why is it frowned upon now? Did biologists and scientists generally just cave into a particular group that believes the truth must be suppressed? I even read the idea of "genetic superiority" is wrong in the eyes of contemporary science because it isn't "measurable."

Use electron beam physics to make your own 3D Metal Printer. Support this open source project

No.14362442 ViewReplyOriginalReport
Hello! My name is Agustin Cruz. I'm making a 3D Metal Printer for making parts with titanium and other metals. Is a low cost, Open source project, so everyone can make their own 3D Metal Printer.

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. 3D Metal Printing is an impactful tool. Making it more accessible will democratize science, engineering and empower people. This low-cost hardware will be able to accelerate innovations in and lower barriers to scientific research.

This printer uses an electron beam to selectively melt each layer of metal powder, causing the powder particles to fuse together. After one layer is complete, the build platform is moved down one layer in height. The re-coater comes in again with a fresh layer of powder, and the electron beam starts to induce the fusion of powder particles, causing the new layer to form. This process is repeated until the entire part is finished, making a solid metal part.

This is what I do fulltime. Doing all this takes a lot of time and effort. Now the project is opening to the community inside a crowdfunding model. The design, tests, updates, will be shared so I can receive some support and continue working 100% in this project

I made a Patreon, if you want to support my work:
