No Infill For Small Objects I am unable to get my RepRap to properly perform the infill on small objects. Even though the objects are solid in the CAD models and the infill is set to 100%, small shapes come out hollow. I've attached photos of a test piece I've been working with in an attempt to correct the problem. The piece includes a 2.5mm, 5mm, and 10mm diameter cylinder. I have a 0.35mm hot end. My gcode is generated by slic3r. The object in the center of the photos is the current "baseline" configuration for my printer. The object on the left is the result of changing the extrusion multiplier from 1 to 1.3. The object on the right was made by increasing the number of perimeters from 3 to 6. Increasing the extrusion multiplier did not fix the infill problem and made for a very messy print. Adding more perimeters made the 2.5mm and 5mm cylinders solid, but caused the 10mm cylinder to require less infill and become hollow. Can anyone offer advice to make the infill work properly?

Sounds like the slicer could be acting up. Try using another slicer, probably Kisslicer or Cura.
I'll have to try that. I have an old version of Slic3r, so I'll try downloading the newest version of that first.

How's the filament coming of the spool if it catches it will pull on the extruder what percentage of infil set in your slicer
I don't think the filament is catching because the parts that don't get filled are missing material consistently, rather than sporadically losing sections.
The objects are solid in the CAD models and the infill is set to 100%.]]> MaFraL Printing Sun, 06 Jul 2014 22:14:06 -0400 https://reprap.org/forum/read.php?262,377416,378648#msg-378648 Re: No Infill For Small Objects https://reprap.org/forum/read.php?262,377416,378648#msg-378648 chris33 Printing Sat, 05 Jul 2014 13:49:15 -0400 https://reprap.org/forum/read.php?262,377416,378604#msg-378604 Re: No Infill For Small Objects https://reprap.org/forum/read.php?262,377416,378604#msg-378604 chngyian Printing Sat, 05 Jul 2014 12:25:45 -0400 https://reprap.org/forum/read.php?262,377416,378282#msg-378282 Re: No Infill For Small Objects https://reprap.org/forum/read.php?262,377416,378282#msg-378282 MaFraL Printing Fri, 04 Jul 2014 22:34:53 -0400 https://reprap.org/forum/read.php?262,377416,377775#msg-377775 Re: No Infill For Small Objects https://reprap.org/forum/read.php?262,377416,377775#msg-377775
Infill: 60 mm/s
solid infill: 60 mm/s
Top solid infill: 50 mm/s]]> MaFraL Printing Thu, 03 Jul 2014 15:33:11 -0400 https://reprap.org/forum/read.php?262,377416,377515#msg-377515 Re: No Infill For Small Objects https://reprap.org/forum/read.php?262,377416,377515#msg-377515 chris33 Printing Thu, 03 Jul 2014 05:08:31 -0400 https://reprap.org/forum/read.php?262,377416,377416#msg-377416 No Infill For Small Objects https://reprap.org/forum/read.php?262,377416,377416#msg-377416
