I wonder if rather than "additive" you could do similar with "subtractive" fabrication. Take a wooden board and cnc mill and cut circles on the surface at the appropriate orientations.
- ruined 5y agogenerally it's just a matter of slicing the same source STL file to the appropriate gcode, but in this case the particular geometry (lots of sharp concave angles) seems more suited to additive manufacturing.
- serf 5y agoyes, but it'd require a redesign or very special tooling. that spacing between each mirror 'pedestal' is fairly deep, it'd require a very long end-mill or a five axis machine to be able to get into those crevices. it'd be trivial to carve the needed angle into each 'mirror pedestal' , but the current design doesn't support the premise very well.. still, doable.
- intrasight 5y agoHow about this approach. Just have a collection of wooden dowels with one end milled to be concave at one of 20 or 30 angles. Then you can assemble whatever mirror array you want by selecting and positioning the appropriate dowels. Or sold as a kit made out of plastic hex shaped rods that snap together.
