Printer to replace Z18

[LambdaFF]

Yes, I mean for NinjaFlex filament printing, a over 70 mm/s speed is too fast.

For normal printing, the highest printing speed I have tried is 200 mm/s.

In the slice software I can set it up to 300 mm/s, but I don't think at that speed the printer will give good results...

At these kind of speeds I wonder about the quality of the end result...

show me a video of a printer running at 200mm/s .
And producing a useable print.

That's just ridiculously fast. How do you get the plastic set fast enough ?

Ninjaflex is usually printed at around 20-40 mm/s max. Slower is usually better.

If the printed parts are for end-use, then consider PET filament, which is stronger that PLA or ABS. And it does not need an enclosure, and can be done without a heated bed with the right filament. This opens up the options of printer greatly, to solid ones like the F306 core-xy printer.

Sorry, aardvark

I‘m back. And I took three short videos of 200mm/s printing, please check them on Youtube:

To print with a very high speed, I set a much higher nozzle temperature at 240 degrees, in this way the filament can be melt as soon as possible.

And yes, NinjaFlex needs a slower speed, And I have printed PolyFlex at 45mm/s with my Mankati Fullscale XT Plus, and the result is great!

Why after watching the 3 link, it does not feel 200mm/s print?


Because for me it is clearly between 50 to 100mm/s. The perimeter print is too slow for being 200, can't say about the infil, since the thickness is not that big.


But I am curious about your double extruder setting, did you use paper to calibrate both height?


Oh and dont upload pic on this forum, cuz it sucks lol. Upload on some 3D party hosting and link them, it is far better.

I find that the main print speed in basic setting is not a absolute value for the whole printing,
let me change the inner shell speed, out shell speed and infill speed to 200 mm/s and try again.

I tried again, the printer did not speed up very much.
It seems that the firmware limited the top speed.

Hi, Richard

I calibrate the left nozzle with a card, and the right nozzle is a little higher than the left one, about 0.1 mm higher, I judge it with eyes... and it works good.
When printing with dual filament, the 0.1 mm higher right nozzle works as good as the left one, and it won't impact the object.

I don't see a 20cm movement in 1 sec either. Probably limited in the chain somewhere.
