15.2.4 Object internal strength, or support integrity, or support material break-off issues

31.

If the infill in the interior of the object is not fully bonding to the shells forming the exterior of the object, then you may need to increase the “Infill Overlap” and/or decrease the “Infill Speed” (under “PRINT SETTINGS”, “ADVANCED”, “Fill”).

32.

If a fragile object breaks when you attempt to remove it from the build plate, consider printing the object with a raft: see the build plate’s “PRINT SETTINGS”, “BASIC”, “Support”, “Platform Adhesion Type”.

33.

If support material comes apart or “breaks” during printing, there are a couple of possibilities. You may need to print with a stronger style of support – perhaps“Grid” pattern instead of “Lines” (under “PRINT SETTINGS”, “BASIC”, “Support”, “Support Lines”). Or if you are attempting to build with a really tall and skinny support structure, that simply doesn’t itself have enough structural integrity to hold together during the print, you may need to re-consider how you’re printing: along with your main object, if your design permits, also print some basic “block” sorts of objects in place of the bottom portion of the current support, so that you only need support (using “Support Type” of “Everywhere”) to “fill in” from the top of the block to the bottom of your main object. Finally, older filament that has become brittle is especially likely to cause problems with support material: the brittleness especially becomes a factor for the thin, barely there, supports. If you’ve been printing with a relatively old spool of filament, try using newer filament and see if that produces more successful supports.

34.

If support material, such as a raft, will not break off cleanly from the printed object, you may need to reduce the solidity of the support material, or increase its gap from the object itself: under “PRINT SETTINGS”, “ADVANCED”, “Support”, “Support Type”, “Support Settings”, see the settings for “Support Line Distance”, “Support XY Distance”, and “Support Z Distance”. Note that support material in a “Grid” pattern, while it is stronger than support material in a “Lines” pattern, is also harder to break off. If printing through the Polar Cloud, see the build plate’s “PRINT SETTINGS”, “BASIC”, “Support”, “Support Lines”.
