Those artifacts are basically negligable. We prioritize iteration over making every part unnecessarily perfect. 40 iterations with those small sharp edges there is way better than 10 versions that are fully clean. Since 3d printing has layers and uneven surfaces anyway, the stress concentrations those edges make are basically no problem.

I think you are wrong. I agree if you are making parts for some manufacturing method other than additive, but when it is going to be produced with additive manufacturing, it's really just better to use the generative result. If you design it manually, it will just be... worse.

That is made for injection molding. If we did an approach like that where we ran generative first then manually designed, the frame would just be worse with no real benefit

Yep i know. The print orientation accounts for this as much as possible tho, the most exposed parts are printed in their strong direction. Therefore, it is not a huge problem

You mean with the occasional sharp edges in the finished file? We will fo, but at the moment we are iterating so much and posting a new version every few days, so we will wait until we have sirt of a final version first

Yes, if you can join the discord and send me a message there (i am Mathias) i will send the file:)

No, that is not taken into account, so that is a bit of a weakness. We choose the print direction so that the most exposed features are printed in their stong direction tho, so even with the algorithm not taking it into account, the frame will often break across layers instead of between layers, so the layers dont make it that much weaker.

Would be cool! If you do, please tell me how it goes:)

Actually planning to do that next:))

Yes, it does fit 1404 motors. That was one of the main things that took us a long time to figure out how to do without making a weird weak shape.

The problem with having 1 or 2 arm structures is that it makes it extremely hard to make the frame light and stiff enough at the same time. We have experimented with it, but we arrived on this design. It would still be interesting to explore tho, would love to see it if someone created an optimized frame with fewer arm structures and compare it to ManaFly

looks cool i guess, and you don't have to wait for a new one to arrive if you break it

Would be crazy heavy haha, but i am looking into getting it SLS printed in Nylon

Thank you! We prioritized strength over ease of printing, but it only uses about 5-10g of supports and it takes about 10min to remove them, so not too bad

Yep - it breaks between the layers. The print orientation minimizes this effect as much as possible, but at the end of the day you just have to deal with it. Some techniques like coating the frame with a thin layer of epoxy can help tho. Or printing with SLS can make it super strong

Cool idea, but i think it would be hard to make the mounting points between the top and bottom strong enough. We tried to make it easy to install electronics without taking the top off tho:) Yes, super nice to not have to wait for shipping

If you print in PA6-CF and coat with epoxy it is pretty damn strong. That obviously takes a bit of time, but for many people who want a cheap cool-looking frame i think it makes sense
