I do agree. Future is here.
PLACAR ( Poly Lactic Acid nano CARbone reinforced material) 3D honeycomb printed gear doors for the Diamond:
This material has a high ratio of nano carbon fibers and is quite difficult to process ( requires high printing temperatures and a hot bed as well as a special surface treatment before processing). I also had to make a specific 0.65 mm laser drilled printing nozzle for this purpose. Note that the piano hinge recess and control horns are included in the printing process.
The part is crazy light ( less than 10 grs ) and extremely stiff. Very impressive material.
