Printing Flexible Filament at 200mm/s

That was crazy fast!
I doubt much, if any, of that print actually happened at 200mm/s. What’s your accel and jerk? How long were the longest straight line infill strands?
And… what’s the point if it looks like garbage when you’re done?
What the hell how does that even work. 200mm is excessive even with rigid filaments.
@Griffin_Paquette Feedrate doesn’t matter as far as the extruder is concerned, volume flow rate does. Drop the layer height to 0.1mm and you can run very high feedrates without the extruder falling behind. But I don’t think 200mm/s is happening here.
I can also confirm that it’s not going to 200mm/s, i was playing with the limit of my printer and to get those speed in a small piece your acceleration need to be really high…
I have also printed Filaflex at 200mm/s with 5000mm/s^2 acceleration (see infill):
Z=0.1mm
Infill = 200mm/s
Outer Perimeters and top/btm shells = 100mm/s
Inner perimeters = 150mm/s
Acceleration = 5000mm/s^2
Nozzle = 0.4mm
What model printer is that?
Yes it’s a really good performance with filaflex !
@John_Foreman is the question aimed at me or the main post? Mine is a ZOK printer, corexy with Chitu electronics, prototype from Recreus.
@Steve_Wood_Gyrobot main post. The printer in the video
@Steve_Wood_Gyrobot although after watching you video, what is your printer?
@John_Foreman It’s our own custom made printer
This is just to show people you still can print fast with flexible filaments, with a good extruder. Also 200mm/s is the speed set for the slicer. 1st and 2nd layer is 100mm/s others at 200mm/s.
Very nice, what kind of extruder do you use?
@Frank_Kirchner that’s the BPS V3 extruder.
Ok, this is not to put down the poster’s printing because the printer is printing flexible filament faster than most people can print at but because I was just talking with @Ryan_Carlyle just last week over dinner about this very subject. I have always wanted to put together something to show what Ryan mentioned as being the real reasons why the 200mm/s is just not correct. Here are two videos of my printer, in both videos the printer is printing the exact same sliced file (in Dry Mode just for testing), so nothing has changed in the file. The only differences are the first video shows a print at 200mm/s as a typical user would see it and the second video shows 200mm/s as close to the real thing as possible. This was achieved by changing the Jerk and Acceleration settings on my printer. Enjoy the craziness of video #2, it made my iPhone pause a few times trying to process the video stabilization. #1: CoreXY speed test #1 - YouTube #2: CoreXY speed test #2 - YouTube
Good video, James
