Help with 3d designing (fusion 360 - autodesk)

[gtx1060=value]

Well - i've seem to run into an issue - my girlfriend insists on decorating our home with 3d printed custom easter eggs - but we've done the designing of the outside but i can't seem to be able to hollow out the egg so that i don't waste precious filament on that - anyone know how to hollow out the inside of a spherical component in any autodesk program???

help

Could you design the item in two interlocking sections?

oh yes i can do that but... how would i shell those out so that it's like an egg shell?

Its called the "Shell" command seen here towards the right:

 

 

That should do what you want. This is in Inventor, I think its called the same in Solidworks.

tried it - just shelled it out in the shape of a cylinder down the middle

Really? I made a quick sphere and it shelled correctly without issue. Did you select all of your features? How did you draw the egg shape?

 

I drew a circle on a plane, cut it in half, the revolved around the axis to make the solid then shelled it. Same method applies to making a basic egg shape.

i created a sphere and then just editing it's body in the form creation page - i'll try again - can you send a screenshot of what settings you used to shell?

im only choosing one face - the bottom flat portion - could that be the issue? should i choose the entire thing?

that sounds likes it your problem. By selecting only the flat bottom I would even assume it would just shell the cylindrical center.

 

As far as shell settings, there really aren't any; inside/outside/or both, and then how much to shell. You obviously want an inside shell.

uhm... print with 0% infill and a thicker wall for strength?

still doesn't work - i think it's because i've cut parts out using rectangular extrusion cuts to make little designs - what do i do about that?

tried it once - didn't work - welp

which slicer do you use? and which printer?

cura - and in terms of printer - my friends - he has a wanhao - just like you

mind sending me a screenshot of cura, with view mode set to layers, and the slider in the middle (so the top of what's visible is the thickest part of the egg, roughly)

i can't because it was on my friends computer - but essentially the egg collapsed in on itself - even with thicker layers and walls and higher infil

i honestly have no idea how to shell it - nothing is working - i mean it'll probably work if i roll back to pre designing and just the shell but i won't be able to get the design back after that

0.1mm layers, 1.2mm top/bottom/wall thickness, and around 13% infill is usually my lucky shot, but the wanhao doesnt like printing round very much, once i figure out a reliable setup i'll share

[manikyath]

so.. i've found after some tweaking this gives pretty nice results:

- 0.2mm layer height

- 0.8mm on all the vareous thicknesses

- infill is kinda print-dependant to find the ideal, but my rule of thumb of 13% should do, as long as that means the widest part has at least 3 support lines in it.

i am printing this right now at my local libraries ultimaker 2 (canada taxes people too much) and it just collapsed - im still paying 3 bucks too
