Carbon fiber science is more about the layup of the fabric to create strength in planes than it is just about making a uniaxial shape.

No doubt, I like it, but this is HARDLY a giant step forward.
There are labs that have been weaving carbon fiber into complex 3D shapes for a decade, or decades. These 3D shapes are purposefully designed for strength and optimized physical properties, not just for their CF content.

hmm
yea. I agree its hardly a revolutionary step forward knowing that... Maybe we could say from the nature of the video they where promoting their accomplishments and the machine...

They probably printed one blade thinking, "lets try this out against the regular blade.

Likely have some smarts there, but the mere fact that you have to balance the blades may not have ever even crossed their minds

Is the dream liner experiencing a problem with it cf wing ?? I n not knocking but very neat thing s happening in the 3d printer revolution

Actually, the Dreamliner did have some initial problems with its CF wing box. However, there is quite a bit of difference in CF/epoxy matrix layup that is bonded together under high pressure and temp vs just encapsulating a strand of CF in a melted plastic design.

I actually posted a thread couple wks ago and the article made me believe the were mixing cf into the plastic vs a strand coated in plastic ?? Humm here is the link

Milacron was making 7 axis CF taper layers back in the early 90's and one of the first projects they did was the intake tunnels for the F22. Once the tape was layed up on the forms it was vacuum bagged and autoclaved. Once the part was done it was trimmed with high speed routers.

I like the idea of this but I want to see more of it in action.

I went back and looked at the original article, and can maybe see some differences from what I originally thought, although my general perception is that this will never be nearly as strong as the autoclave laid up CF cloth and epoxy. I would envision it along something like the Master Airscrew glass filled nylon props vs the full molded CF props where the CF strands are running the full length of the blade, sort of like rebar in concrete.

I don't really know if the current Dream Liner wing boxes are starting to get fatigue cracks, but that was just the issue I was referring to in my earlier post, plus one of the test boxes failed at way less than its design load. That was in part why the development took so much longer than was originally forecast.

Would you buy something from someone that cannot fly the Mcpx? I didn't think so.

That is back in March and now I can buy Carbon Filament for my Robo 3D R1 PLA/ABS printer and use it. You can even print wood projects with the 3D printers now. They are coming out with new Filaments (the material you print with) all the time to use in these printers.
I love the fact that you can print most upgrades parts for these printers on the print itself. I wish my Heli's would upgrade them self's. Oh Ya, I guess they do when they meet the ground.

Remember 3D printers are for 1 off parts or prototypes not for mass production.
To have a part within a few hours that has close to the properties of a finally carbon fiber lay up with out having to build a mold is a huge cost saving. The labor and time in building molds is very expensive not to mention have to make changes or retooling.
