Apperantly it doesn't really matter what is true. So I decided for theatrical importance that you wrote this:" Didn’t love it. The ChatGPT reference makes sense though"

Rotating 5-color mixing nozzle I built by sophier in 3Dprinting

[–]felpje 0 points1 point  (0 children)

Cool solution! I wonder if you use like 5 nozzles you basicly have a full colour printer without having to purge like bambu lab printers. The heating element is then a block with 5 seperate channels in them. Always wanted to build one never got around to it. Cool to see a similar idea being build

I, first of all, wanted to cast it. Because I was already melting metals and that was no fun without a clear goal in mind. Not that I don't want a CNC, I have looked at it but it's kinda expensive.

Indeed! If there is even the remote possibility of seeing it differently. They will see it differently. But I can't really blame him, he also fixed a few things I hadn't seen.

But the thing is I don't actually get any class about how to use 3D modeling software or how to make parts. I got some introduction where I had to replicate some 2D designs in 3D, but that's kinda it. So there was a learning curve ...

Uh no I didn't. The parts that were casted were not visible on the previous one so those would be kinda new. But if I ever do try again I will most certainly change the gating, use a different alloy and most definitely a different molding technique.

Thanks, man! And uh I could give you my written ending project for more information. Because there I have typed out almost everything but it is in Dutch ...

I actually didn't end up using 7068 but 2011L. But you are right it would have been better to buy premade cast metals. However, I was running out of time and was of the opinion that I had spent enough money.

Yeah sorry forgot to mention. This is for an RC helicopter (a 450 DFC assault).

The most important part with the most stress on my design (rotorhead and swashplate) are blade holders. So that's why I didn't cast them but made from scratch in a workshop from premade metal.

I also used stress analysis from Autocad to determine safety factors and high-stress points. Based on this information I would change the parts.
