Your 3D printer proudly advertises a most print velocity, however that doesn’t essentially imply it’s best to really use it. When print high quality, sturdiness, and printer longevity are your priorities, velocity takes a backseat.
Listed below are some causes to sluggish it down.
You in all probability want a high-flow nozzle to hit these speeds
It’s all about movement fee
Tim Brookes / How-To Geek
I take advantage of a combination of Bambu Studio and OrcaSlicer for my Bambu Lab P2S, and I’ve but to discover a purpose to enterprise past the default print profiles (with a few tweaks to default values, after all). I usually prioritize high quality over velocity, since I don’t thoughts ready for prints to finish. By switching between the completely different profiles—from 0.08 prime quality to 0.24mm commonplace—you’ll be able to watch the velocity worth presets change.
None of those values come anyplace near the marketed 600 mm/s most velocity that my printer is able to. It’s solely once I inform the slicer that I’ve a excessive movement nozzle that I get anyplace close to 600mm/s on the “commonplace” decrease high quality print profiles.
When you haven’t upgraded your printer’s nozzle to a high-flow selection (and it didn’t include one), then you definately in all probability can’t hit these speeds both. Exceeding your printer’s most movement fee signifies that you gained’t have the ability to transfer melted filament by means of the recent finish quick sufficient.
Print velocity sacrifices print high quality
Slower is best for element and end
When you’ve ever fiddled with slicer settings, you’ll in all probability bear in mind that higher high quality finishes take longer to finish. There are just a few causes for this, however quite a lot of it comes all the way down to layer peak. Thinner layer strains permit for extra detailed objects, however smaller layer strains additionally prohibit movement fee.
On high of this, a print head that strikes shortly is much less exact than one which strikes slowly. Sooner motion means extra vibrations and momentum is carried into the print, which may end up in layer strains that don’t fairly match up on the mannequin (leading to what is called “ghost outlines”).
Print surfaces will even look extra uniform at slower speeds, which signifies that consistency calls for slower prints. If you wish to make use of additional techniques for improving the look of your print, like fuzzy skin and ironing, these will even add time to your print.
Sooner prints can be weaker
Take your time if energy is a precedence
Not all 3D printed objects have to be sturdy, however people who do will profit from slower print speeds. Quick speeds may cause layer adhesion points, the place filament is under-extruded in some areas as a result of print head transferring quicker than the speed of extrusion. This may introduce weak spots to your prints.
Typically talking, slower print speeds will help make sure that filament is extruded evenly. Concentrate on the flip facet of this, the place the earlier layer cools quickly and reaches ambient temperature earlier than the print head has deposited one other layer. It’s also possible to get weak spots when contemporary gentle filament is laid on high of hardened filament.
You may mitigate this downside by selecting a cheerful center floor, or using an enclosed and heated chamber.
Sooner extrusion might result in extra failed prints
Extra filament, extra issues
Tim Brookes / How-To Geek
All hotends have a most movement fee, which defines the quantity of melted filament that may cross by means of at anyone time. The nearer you get to this quantity, the much less room there’s for error. Excessive extrusion charges usually tend to result in extruder jams, which in flip will trigger prints to fail and require a prolonged clear up or perhaps a new nozzle.
Via regular use, filament can get caught in your printer’s nozzle. You won’t discover this at decrease print speeds, however the extra filament you attempt to transfer by means of the hotend, the higher the potential for points. You may try performing a cold pull periodically to clear any trapped gunk out of your print head.
Sooner print speeds additionally usually require increased temperatures, because the filament spends much less time hanging round within the hotend earlier than it’s deposited. This may result in warmth creep, the place warmth from the hotend makes its approach up the print head and causes the filament to melt earlier than reaching the nozzle, inflicting blockages.
In case you have a “bedslinger” open printer, you may additionally discover that quicker print speeds outcome within the print turning into dislodged from the mattress because the mattress must transfer quite a bit quicker, shaking your print on the identical time. This may trigger your print to “spaghetti” out.

The Prusa MK4S 3D Printer is without doubt one of the most well-known and well-loved 3D printers in the marketplace. As one of many principal firms behind the open supply initiative of 3D printing, the Prusa MK4S nonetheless helps open-source software program and firmware when different firms are constructing their very own closed-source alternate options. Because the 2025 iteration of the basic Prusa 3D printer, you will get all the fashionable facilities together with quick and dependable printing, simple setup, and Prusa’s confirmed reliability.
When you’re determined for a print to finish, take into account lowering the infill density. This can make the print weaker, whereas consuming much less filament, however much less printing means much less ready round.
Alternatively, it’s also possible to save time by printing a small slice of a tight-fitting item before you commit to the whole print.
