One of the fundamental print speed issues is the extruder flow rate, a variable aperture nozzle could in theory help and changing nozzles, but fundamentally if you can increase the flow rate you can increase the print speed. So could we detail the limitations to increased flow rate here, which may help maximise the potential of the system. If this works can we make this thread sticky and in future add to the wiki? https://reprap.org/forum/read.php?70,73512,73512#msg-73512 Sat, 07 Mar 2026 13:21:21 -0500 Phorum 5.2.23 https://reprap.org/forum/read.php?70,73512,73597#msg-73597 https://reprap.org/forum/read.php?70,73512,73597#msg-73597
My 20x20x10 test print with 20% infill was 1/3rd done when I started watching it, and is only finishing as I type this!!

I will need to up my speed lol]]> AgeingHippy Plastic Extruder Working Group Sun, 13 Feb 2011 06:00:19 -0500 https://reprap.org/forum/read.php?70,73512,73591#msg-73591 https://reprap.org/forum/read.php?70,73512,73591#msg-73591 [blog.ultimaker.com]]]> NewPerfection Plastic Extruder Working Group Sun, 13 Feb 2011 05:38:59 -0500 https://reprap.org/forum/read.php?70,73512,73547#msg-73547 https://reprap.org/forum/read.php?70,73512,73547#msg-73547
another max speed limiter would be how quickly a build dissipates heat, and how long you have to wait for each layer to cool, but this can be sped up by a fan.]]> Buback Plastic Extruder Working Group Sat, 12 Feb 2011 12:40:50 -0500 https://reprap.org/forum/read.php?70,73512,73512#msg-73512 https://reprap.org/forum/read.php?70,73512,73512#msg-73512
