# Key Ideas from ##hplusroadmap IRC Discussion

• Open-source CAD and engineering software packages were shared, including nanoengineer (nanotech CAD), opencascade (3D mechanical engineering kernel), heekscad, freecad, and openscad, with resources available at diyhpl.us.

• The SKDB project was discussed as a system for managing and sharing engineering knowledge, blueprints, and machine tool specifications, pointing to potential standardization of open hardware designs.

• Nanofabrication challenges were debated with references to Robert Freitas' work on molecular manufacturing, including a philosophical disagreement about whether advanced nanotechnology development requires AI assistance or can be achieved through human-designed algorithms and abstraction.

• A significant gene therapy paper on treating red-green color blindness in adult primates was shared, alongside discussion of AAV (adeno-associated virus) genome resources and bioinformatics data formats.

• 3D printing technologies and resources were extensively discussed, including RepRap models (Prusa and Huxley), TechZone's modified designs, and a Thingiverse data archive containing numerous 3D printing designs.

• Technical conversations about STL file rendering compared various approaches (POV-Ray, OpenGL, Three.js) for displaying 3D models, with particular interest in headless rendering solutions like OpenMesa.

• Biohacking applications were briefly mentioned, including subdermal magnetic implants with a shared PDF resource for those interested in this form of human augmentation.
