99% konstruktorów nie pracuje na CNC. No ale jeżeli projekt ma przeobrazić się w rzeczywistość to jednak trzeba go zrobić tak aby był wykonalny. :)

Jak chcesz takie coś wykonać? Wytrzymałość elementów o takich kształtach też nie jest zbyt duża :)

No trochę nietechnologiczne kształty :P

Cool to see it :) Unfortunetely last time it started to be popular problem in mechanics. I saw many broken parts that get crack even when teorytical tension was about 3MPa. In fact shape mistakes in assembly was so big that they would get brak even if they would work without load. But I think that modern univercities forgot about old knowledge. And modern programs can push us to many mistake.

I think that first you should mill a surface, positioned against each other with high accuracy. Thanks for this material would be much stiffer. Small accuracy can give you huge montage tensions. Many parts gets fatigue very fast, not becuase they are wrong designet, but becuase they have huge montage tensions. For example tension under huge impact can have 60 [MPa] but montage tension can add to this 70 [MPa]. Thatswhy in your place I would use water jet tu cut rough shape and then I would drill the holes through all. After that i would use this holes to base for milling of other surface.

Najbardziej bym chciał coś lekkiego i zwinnego na kołach 26" ale z geo do DH i skokiem około 180mm. tak żeby nie walnęło na dużych dropach ale żeby można było sie przejechać tu i ówdzie.

This movie shows perfectly how much freedom and funn a bicycle can give :)

Pole Bicycles Announces New CNC-Machined 'Machine' - Press Release
@WAKIdesigns: In my opinion it would be passible to make durable frame, even by weldable aluminum alloys, which would survive even over 20 years without any problems. Especially when you can use T6 treatment after welding and technologies like hydroforming to put welds in not responsible places. Shoe on the downhill frame are not designe to be durable but to look nice. They have wrong shapes of profiles, or even shape of profiles path. Đây là sự phân cách tuyệt đối siêu hợp nhất: https://www.pinkbike.com/photo/6146136/ Some companies know how to make durable frames, but they will do one to weak point to make it crack after waranty. For example I had 3 DEMO in my life, all 3 craced in chain stay becuse Specialized made a point to make it crack after 2 year of riding. On these frames I had many crashes like this: https://www.pinkbike.com/video/235982/ I can not say how many times my frame hit the tree. But after 2 years of riding in the chainstey was broken. That becaus there is a wrong designet to get crack not because fatigue of aluminum is too low. Everyone who has even a small knowledge in construction calculates the construction of this super stupid, and wrong shape: https://www.pinkbike.com/photo/14796223/ Even the roof skeleton of a hundred-year-old bus station is better. Costs of produce of aluminum frame are much lower. Also CO2 and most of metal trash are much safer for enviroment than polymer matrix composites. Another problem with CFK is super low resistance for impact. Small inpact can start delamination proces which can be dangerus.

I also was thinking about something like this but there could be problems with bearing durability.
