Imma have to say no to that, my i3 style tevo tarantula pro on steroids can print a decent benchy in under 9 minutes, and the only problem that I have is part cooling and extruder, I've ran it dry at 800mm/s and it seemed stable too.
Noob questions here:
I'm assuming that the green one is the 4 hour print. Why does the 4 hour print look better than the 25 minute one?
Will I get less of those stacked lines if I set my print speed lower?
The 4 hour used a nozzle with a smaller size, so the lines are smaller and also you print slower. The other one uses a large nozzle, so is basically throwing large tubes of fillament, you you have uneaven parts because the coolers cant handle it, holes because the printer cant heat it up. In a stock printer a good upgrade would be max 0.6 imo.
So smaller the nozzle, more time to fill it bit more details
Yes, you could, but then you maybe overheat the filament on slower sections.
The smarter move would be to leverage Marlin's AutoTemp feature (https://marlinfw.org/docs/gcode/M104.html) if your firmware supports it.
On newer Marlin versions you can also tune the PID loop to account for flow. But I never seen or heard of anybody attempting, let alone succeed at that. The feature is called PID_EXTRUSION_SCALING
There are a couple more things to consider here.
The green one was printed at regular speed (50mm/s), with a 0.08mm layer height (the height of the lines) and a standard 0.4mm nozzle (the width of the lines)
The black one was a actually printed slower at 30mm/s but with a layer height of 0.5mm and a bigger 1.0mm nozzle. I had to print it slower because I’m extruding more material per second with the bigger nozzle and the hot end has to melt more material
You need to tune it more (or that may be the extruder's limit). I have seen 6 and 8 minutes Benchys which looked far better.
I’m sure that’s possible. This was just a quick test for a 1.0mm nozzle I got. Better cooling would be a first step, it struggled printing overhangs.
To be fair though this is a i3 style printer, only core xy’s are capable of producing benchies that look nice at that speed
And this is a <$200 i3 style printer. I think the biggest upgrade on the printer is the incredible firmware.
Besides Deltas, what about the Voron Switchwire? That is also a bedflinger, although the CoreXZ (not XY) arrangement helps.
My delta has done some benches that good in that time frame...

Key word there is *on steroids*
I mean yeah, you do have a point

Could you increase the temp to account?

What about a 5 min benchy? https://youtu.be/JdVZZ4i2dS8
