Looks good, however, the filament you are using is not appropriate for this kind of work I think.
There are specially made resins and filaments called “castable” which allows uniform melting of the part when Boiling alu of whatever is poured on top of it. Have you considered castable filament ?
Oh, oh, oh ! No such result has been reached on this forum. Congratulations !
Looking forward to seeing the performance differences between the printed and the cast versions !
As per the ESC box above the mast, it looks promising. Maybe no machine time or at worst a fast surface finish between lid and box on each face will be needed ?
The red sand is very nice if you use it directly to shape inside
and for the other I sifted with a small sieve and I mix it (50/50) with a very fine plaster
I start in foundry so I have everything to learn
it’s really interesting and exciting to learn new techniques.
I need to improve the layout of vent and pipe for cast
Do you know if a “free” software can modelised this ?
You mean, your receiver is just connected to 5 wires: Bat, Mot, Pwm, Tx and Rx ?
I got a crazy idea that should be cheap and effective: in addition to cast aluminium prop and ESC block, what about making a front wing with 2 half molds (flasks) ? Then there is this sleeve on the wing to fit on the fuselage that the Gong Hellvator or brands like Axis don’t have.
Does anyone here know who made the efoil flipsky.stl ? (the nose cone in post #12)
I would like to have the water inlet part (part that connects to the hose in the mast) moved a little bit more backwards. Unfortunately I can not edit this file.
but the waterintake is not from me.
I downloaded the STL and take a look.
I think it is totaly on the wrong position.
Or the tube go outside there and looking in front, but than zou have problems with the screw.
Did some one print that adaption and test it?
