A new generation of material: Printed Composite Honeycomb by Ultimate Jets.

I am using nylon for certain types of parts, but these new materials are 100% nylon free.
The biggest reason for this is that I am looking for material that are very easy to glue. Nylon is a release agent. So very glue un-friendly!!!

Thanks guys.
This is the future of aerospace design.
For example, consider the manufacture of a propeller. Being able to print an inner core that is 3D honeycomb, ballistic grade and conforms to the mold shape by 2/10 mm opens a new area in composite design.
BTW the CAD software we use to compute composite aero structure resistance are not able to modelize such a material yet. So the gain in weight and resistance for very complex parts and whole assemblies is unknown yet!

Additive manufacturing with new composites materials is here and evolving. Not sure I would trust a propellor made from only FDM PC/ABS for a high performance application even if you call it "Ballistic Grade". I have made toy grade helicopter blades from stereolithography/epoxy for functional prototypes.

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.

I have some parts made like this that I cannot show here. I can ensure you that this stuff is absolutely amazing.

A sample of the 3 axis honeycomb structure printed from PYCABS.
On the z axis, the structure is octogonal.
On the x and y axis the structure is exagonal.
