![]() ![]() Layer height Height of the individual slices/thickness of each layer. However, with bigger nozzles, you can slightly increase MVS due to lower mechanical resistance - basically, it's a bit easier for the filament to get pushed through the nozzle.Īnd vice-versa, with smaller nozzles, you'll have to decrease MVS a bit. Some options will only appear when Expert mode is selected. In this guide, well cover how to import profiles in PrusaSlicer that are not included with the software, and how to export your custom PrusaSlicer profiles. Intuitively, it may seem that the nozzle diameter shouldn't affect the maximum amount of plastic that the hotend can heat in a given amount of time. Other hotend designs allow even higher flow rates. Flexible materials are suitable for numerous printing projects due to their elasticity. The Volcano hotend from E3D increases this to roughly 25 mm 3/s but does require modding the printer and the firmware. TPU is short for Thermoplastic Polyurethane and is a flexible filament. If you need to push more filament, a more powerful hotend will be necessary. A safe value that leaves some space for imperfect setup (idler tension, slightly jammed nozzle) of 11.5 mm 3/s is realistic. PLA, PETG, ABS, ASA, TPU, Nylon, PC, Carbon Fiber and more. The E3D V6 hotend that ships with the Original Prusa i3 MK3/S is advertised with a rate of 15 mm 3/s. Polymaker is a high quality 3D printing filament manufacturers. The overall maximum volumetric speed you should use depends on your hotend. decrease it for FLEX filaments (so you won't have to create a new print profile for flexible filaments, just a filament profile). ![]() In filament profiles, you can adjust MVS as needed to account for filament characteristics, e.g. In your print profile, you'll typically have an all-around default value based on your hotend hardware. These are the TPU settings I use for Disclaimer these settings are proven to work great for me when using Slicer: Simplif圓D and. Heres where you can find it in PrusaSlicer, under Filament Settings. Independent MVS values can be set under both Print settings and Filament settings. As TPU filaments can improperly extrude during the printing process, resulting in. Max volumetric speed = Layer Height × Extrusion Width × Speed Rather than trying to calculate a range of speeds for combinations of different nozzle sizes, layer heights or extrusion widths, you can simply specify the speeds and settings you desire, then let MVS regulate speeds at slice time when and only if necessary. This gives PrusaSlicer users a huge advantage. The MVS setting essentially creates a manager for the maximum amount of filament that the slicer will attempt to push through your 3D printer’s hotend. The Maximum volumetric speed setting (MVS) is one of the most powerful features in PrusaSlicer. ![]()
