I made curves from the top to the bottom.
Mirror the side and place it next to the first side.
After mirroring, loft the curvesides seperately:
1. Select one curveside, click on ‘surface’> ‘loft’ > ‘ok’.
2. Do this for both sides.
Step 3: Holes on the Front and Back
Create a surface like the red line above. Mirror this surface. Select both new surfaces and click on ‘join’. Do this also for the beak of the chicken.
Finally, select all, click on ‘surface’ and then ‘loft’ then just ‘ok’.
Now the chicken is just 1 part and ready to print with Cura.
Step 4: Ultimaker - First Printing
To avoid that problem, I rotated the chicken in Cura 45 degrees, so I was sure Cura would add supportmaterial. I used all the time the same settings.
Layer height: 0,1mm
Shell thickness: 0,8mm
Enable retraction: on
Bottom/Top thickness: 0,8mm
Fill Density: 25%
Print speed: 80mm/s
Printing temperature: 230degrees
Support type: everywhere
Platform adhesion type: none
Step 5: Ultimaker - Second Printing
Step 6: Ultimaker - Third Printing
Scale X: was 1.0, I made it 2.0
Scale Y: was 1.0, I made it 2.0
Scale Z: was 1.0, I made it 2.0
Now it was twice as big. The chicken is still rotated 45 degrees with the same Cura settings.
The printing took 1,5hours and went fine. The head was printed perfectly.
On one side was a lot of support material, I removed this by breaking it with a little force and a sharp knife.
