Fast Print Presets for PrusaSlicer

These print profiles (or “presets” as the kids are now calling them) make for faster prints, compared to Josef Průša's profiles of similar Z-axis resolution. They can often produce fantastic aesthetics despite their speed, but their focus isn't on intricate details of tiny figurines. Their goal is simply to complete a print quickly without introducing structural flaws.

I print smokin'-fast through a combination of moderately high linear speed, exceptionally wide extrusions, and combined infill layers. I stick to none of these approaches, however, where experience proves them impractical. For instance, I print overhangs rather slowly, I severely restrict perimeter accelerations, and I use normal extrusion widths when printing directly over non-solid infill. But I maintain the highest possible volumetric flow rate whenever it's not quite insane to do so. In addition, I use reliable but speed-optimized approaches for infill and support.

In these print profiles, the settings are tweaked all around to give my favorite smokin'-fast but not-quite-insane defaults. I provide profiles for nozzle sizes from 0.4 to 1.0 mm. I print mostly with a Prusa™ Mini+, but these profiles are not printer-specific. They're meant to work with just about any FFF-style printer.

In addition to the “dang fast” general-purpose profiles, good “spiral” profiles are provided as well -- for fast, sturdy, vase-mode prints.

Instructions

Put the .ini files in the directory where you keep your print profiles. (There's also a universal cross-platform way, through PrusaSlicer's menus: File->Import->Import Config…)

• In Linux: ~/.config/PrusaSlicer/print

• In Windows: C:\Users\[name]\AppData\Roaming\PrusaSlicer\print

• In MacOS: /Users/[name]/Library/Application Support/PrusaSlicer/print

Of the several print profiles in this series, the coarser print profiles tend to be the fastest. A 3dbenchy tugboat is included as a benchmark test.

Troubleshooting

If you happen to experience extruder slippage, which causes a clicking sound as your printer tries to push plastic through the nozzle faster than it can melt the plastic, then try any of the following remedies:

• On your printer, tighten the extruder's tension screw.

• In your slicer software, reduce the filament's maximum volumetric flow rate.

• In your printer's menu, reduce the speed multiplier.

If your prints come out slower than you expect, then check your filament profile. It may impose a filament-specific max volumetric speed.

For a filament that works especially well at high speed, try PolySonic™ PLA and my PolySonic™ filament profiles.

Ludicrous Speed

The stable “dangfast” presets assume typical 4th- or early 5th-generation hardware, including a mediocre cooling fan.

For higher raw speed, try the experimental “aggressive” presets.

If it happens that your hardware has a spectacular hotend and exceptionally good part cooling, then by all means dabble in exceeding all limits set here. Don’t let me hold you back.
