Prusa XL print speed double that of Bambu X1C
To begin, I began learning to print 2 years ago on an older Sindoh 3D WOX, upgraded to to a Bambu X1C, and recently added a Prusa XL Multi-tool. I run a Makerspace at a University so our prints are varied and the machines run near constantly. Print time is a growing issue with higher demand for prints.
I have sliced a simple pumpkin clicker fidget.
In Prusa, I sliced the file using the default profile for PETG and the default 0.15mm Quality
In Bambu, I slicked the file using the default profile for PETG and the default profile for .16mm High Quality
The Prusa is estimating that the file will take 1 hour and 11 minutes to print and the Bambu estimates 43 minutes. I have tried using the knob on the Prusa to increase the print speed but I always get issues with the model.
We decided on the Prusa due to its print speed being faster than the Bambu's, but it prints nearly 1/3 slower than the Bambu. How can I speed the Prusa up to at least match the Bambu?
RE: Prusa XL print speed double that of Bambu X1C
For such small things you're going to need to do your own speed tuning and profile setups if you want the heavy XL gantry to overcome inertia like a lighter printer without sacrificing quality. The 'speed' of the XL comes from not having to purge filament in multi-filament prints or from not having to cut up large models into multiple plates. The XL won't win races if the metric is small objects.

You can tweak the settings for speed if you wish - by default Prusa presets aim for durability and repeatability, Bambu *might* have chosen to emphasise headline speed for the impatient user as an advertising ploy.
I have not had much to do with institutional printing but a local school more or less doubled their throughput by changing from printing in submission order to holding back longer prints to start them at closing time, allowing them to run overnight.
Directly dialling up the speed at print time is rarely successful; instead review the many threads here about increasing speed - you are exchanging quality and an increased chance of failure for time and never try it with TPU - but it can be done.
...and its very much print dependent: try slicing a complex multimaterial part for both machines and even Prusa's conservative presets win hands down.
Cheerio,
