It would be really interesting to see a database of each hotend at different temperatures and using different filaments, seems like something CNCKitchen would tackle but it would probably end up pretty similar to the values above. ![]() No one has done a real comparison of every hotend and what they’re actually capable of for max flowrates so take these values all with a grain of salt. ~110mm3/s for the SuperVolcano (E3D claims 11x the standard V6 but I’ve never seen anyone push it that far) ~80-90mm3/s for a Mosquito Magnum+ (Slice claims around 90mm3/s on ABS but they did their testing at 300☌) ~14-16mm3/s for a SF Dragon, DragonFly and a little bit higher on a SF Mosquito If your stock Creality extruder is holding you back I’d highly recommend a BMG clone from TriangeLab.Īnyways, with a good extruder and the only limiting factor being the hotend you could expect to get around: In fact, this is usually the speed of a travel move rather than a print move.” However, that’s much faster than most users would be able to run it. “The maximum print speed for the Ender 3s is 200 mm/s, according to the manufacturer. If it was actually max print speed, it would mean the Ender 3 (V2/Pro) extruder and hotend are capable of a Max Flow Rate of 16 mm³/s! That’s ridiculous. I would have to agree that it’s more likely max travel speed, not max print speed. On this site here, is the following quoted reference to Creality’s monstrously dubious claim of a max print speed of 200 mm/s for the Ender 3 (V2/Pro). I say all this as I used it to replace the stock Creality stuff on an Ender 3 v2. I cannot find published specs, but my sense is: 1) it is better than the stock Creality setup, 2) I could not say how much better. I have a Micro Swiss direct drive extruder hotend combo, which is a “drop-in” replacement for an Ender 3 stock setup. Ender 3 (V2/Pro) - and related Micro Swiss combo ![]() I found a published “Extrusion Volume” for the H2 of “600mm/min” - BUT NOTE: that’s per minute, not per second! That works out to only 10 mm³/s - either right at, or barely above, the MFR of 9.6 mm³/s of the stock B1! See data table above for comparison. Based on my research, apparently not by much. ![]() Still, for the then-pricey purchase of the H2 (~$100 then, currently on sale ~$64 or so, for the whole “pre Black Friday” whatever) I had the “impression” the MFR of the H2 would be better. Generally, I’ve been very impressed with the B1’s and I have been able to push fairly substantial amounts of filament through their stock heads and boosted print speeds. I was curious to see how much better, if any, its MFR is compared to the B1. BIQU H2Īlso, quite some time back I bought a BIQU H2 extruder/hotend combo. Then, by use of the Nova calculator, I deduced a decently reasonable estimate of the Normal Flow Rate and Max Flow Rate of a BIQU B1 printer based on its printing speeds - assuming 0.4mm nozzle and 0.2mm layer height. Speaking of which, there is a fabulous calculator tool at /nova that instantly feeds back the correlation between nozzle diameter, layer height, flow rate (mm³/s), filament diameter, extruder speed, and printing speed (mm/s). I am also attempting to document what is the Max Flow Rate (MFR) of various hotends I either possess or have some interest in. I’m seeing how the Max Flow Rate of a hotend (in mm³/s) can be compared to the Flow Rate (FR) of one’s desired printing plan, using the printing formula below: FR = Nozzle size (mm) x layer height (mm) x print speed (mm/s) = mm³/s. ![]() I have been researching what extruder and hotend to get (or to use from my stash). In my considerations/preparations for building a CoreXY printer, which is quite likely to be one of the latest MP3DP designs by V1… I’m just gathering information both for myself and others. * logic for stats on E3D Titan is that it is a remix of the V6 hotend.
