I love OpenSCAD, and I know it will only get better with time. However, to move forward, I've decided to shift my EDF design library to Blender. Blender sports a Python API from which the library can be coded. Blender is an actively supported and developed tool, and can perform everything I require, such as CSG operations.
So I wrote a piece of OpenSCAD code to let me design axial flow compressors (EDF rotor+stator). I wanted to have a go at 3d printing them, to see if I could do it. I've produced the code to make NACA4 airfoils with twist and taper. However, a bug in OpenSCAD forces me to hard code the # of vertices for the foil object. So I may have to abandon the use of OpenSCAD.
I'm starting to get interested in 3D printing an EDF housing and rotor. I think it's feasible, and I've seen some videos of successful attempts by others. I'm investigating how to go about designing these things.
I've been working on the 3d drawings for the F-86 edf jet. I've got most of the hull sections in place. I test printed Section 4 yesterday; Section 4 is the section that will hold the EDF unit. I confirmed there will be no problems installing and removing the EDF unit. However I have to figure out how to set my tolerances when 3D printing, because things don't fit right. Any best practices?
This is looking pretty feasible. With a 4% infill, my 7 sections will weigh about 70-100g each. with everything, I think I can keep the plane to a little over 1kg.
I'm launching this website with zero fanfare. I have no traffic, and very little content. But with time, I'm hoping that will change, just bear with me. I'm currently working on two projects: an OpenSCAD pendulum clock design and an RC jet design that can be 3D printed.
A full winding of the pendulum clock doesn't last long enough yet, but it ticks and it tocks. The OpenSCAD scripts are Free Software.
