was trying 40% fill and the lines are still still pretty close together. what is it 40% of. is the fill amount over a certain area? ie. 40% fill over 1cm sq will be denser than 40% over 100cm sq. https://reprap.org/forum/read.php?1,169711,169711#msg-169711 Thu, 11 Jun 2026 09:44:19 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,169711,174731#msg-174731 https://reprap.org/forum/read.php?1,169711,174731#msg-174731 i have been using 50% which somebody suggested.
tried 20% the other day for something (flat piece) and it work good too.

basically am printing (fancy) boxes* - need a value that is ok on the flat bottom (4-5mm thick ie. 25 layers or so) and then when it starts printing the vertical walls (4mm and 2mm thick) will be a bit more solid. the 50% seems to go to almost solid when the walls are 2mm thick which is great.

A bridge is any point where the extrusion has no support, is extruding in mid-air, thus needing anchor points at both ends.

I've never seen slic3r do any bridging where there is a solid base in the stl file, regardless of percentage of fill.


It is up to the user to select reasonable percentages of infill and number of solid layers, based on the model and layer height. Sometimes it requires quite a few experiments.

If you do want a bridge on the first top layer, or at difficult areas, you could make a hole in the model at the appropriate place.

I used to experimented a lot to use less filament, but now I just use 50% fill and three solid layers, it works every time for printer parts, and they come out nice and solid every time.]]> Nudel General Wed, 05 Dec 2012 03:13:14 -0500 https://reprap.org/forum/read.php?1,169711,169746#msg-169746 https://reprap.org/forum/read.php?1,169711,169746#msg-169746 jamesdanielv General Wed, 05 Dec 2012 02:47:37 -0500 https://reprap.org/forum/read.php?1,169711,169724#msg-169724 https://reprap.org/forum/read.php?1,169711,169724#msg-169724 rogerw General Tue, 04 Dec 2012 22:20:05 -0500 https://reprap.org/forum/read.php?1,169711,169723#msg-169723 https://reprap.org/forum/read.php?1,169711,169723#msg-169723 Polygonhell General Tue, 04 Dec 2012 21:58:51 -0500 https://reprap.org/forum/read.php?1,169711,169722#msg-169722 https://reprap.org/forum/read.php?1,169711,169722#msg-169722 rogerw General Tue, 04 Dec 2012 21:09:12 -0500 https://reprap.org/forum/read.php?1,169711,169718#msg-169718 https://reprap.org/forum/read.php?1,169711,169718#msg-169718 (sorry would try all this stuff but am lucky to get one happy print done a day - too many question not enough printing success).]]> rogerw General Tue, 04 Dec 2012 20:33:22 -0500 https://reprap.org/forum/read.php?1,169711,169714#msg-169714 https://reprap.org/forum/read.php?1,169711,169714#msg-169714 Polygonhell General Tue, 04 Dec 2012 19:53:46 -0500 https://reprap.org/forum/read.php?1,169711,169711#msg-169711 https://reprap.org/forum/read.php?1,169711,169711#msg-169711 rogerw General Tue, 04 Dec 2012 19:44:12 -0500
