Supports?]]> https://www.soliforum.com/post/128530/#p128530 Can you show me the real printed part (internal)?

I don't think the internal structure ribs are enough

to support such large top layers (inside), unless it is a

very small part.

The internal vertical structures act as supports which are adequate to let the plastic "bridge" across them to ultimately form the upper solid layers.

The point is the slope angle must be equal or greater than 45 degree.

Supports?]]> https://www.soliforum.com/post/128266/#p128266 AOYOU3D I wasn't worried about external supports near the bottom, but some kind of internal support near the top. What slicer settings or ?? did you use to get the tops to close cleanly?

Using Repetier Host with its built in Cura - will try standalone Slic3r to add more perimeters at top as suggested.
Thanx to everyone here for 2 years of tips and mods for that @#$%$ Press which now works.

3 or 4 will print much more cleanly, especially if you use a fine layer height.

the stand alone version of Slic3r does have the capability of changing layer heights at specific points. you can use a larger layer height for the bulk of the print, then reduce it for the top few.

Supports?]]> https://www.soliforum.com/post/128186/#p128186 The domed top should not give you too much of a problem printing without support.  Each previous layer should offer a good foundation for the next.  Make sure to turn off Support in your slicer.

Supports?]]> https://www.soliforum.com/post/128185/#p128185 About to print some fake 1920's 01A vacuum tube replacements with clear ABS, modelled in openscad, see BMP.
Will a hollow sphere (tube top) print without internal support, 'cause the top is pretty flat? Tube diameter is about 35mm.
Don't want to print "glass" part upside down or multipart as I want the tube top to be smooth and round.
Black tube base prints just fine as separate part.

Any slicing or printing suggestions?
