PolySpeed PLA ??

[neat comet]

There are more and more high-speed or very high-speed printers on the market (Flsun V400 / Bambulab X1-Carbon / soon Creality K1)

I noticed that polylite and polyterra are not very suitable for high speed especially polylite PLA which has difficulty being printed in the infill.
Temperatures must be increased significantly to print quickly, which deteriorates print quality.

Is there a way to get a high speed filament out? Some competing brands already offer this kind of filament

You can print pla, pla pro, draft all at 1m2 if your machine can get there. I’ve never seen anyone hit the top end of it. What kinda troubles have you ran into and what temps and feeds?

At 400mm/s in the filling on the V400 at 220 C the PLA polylite cannot keep up

Bump your temp to 250c

You may be hitting the flow rate of your hot end as well

You might also consider using a CHT nozzle.

Slow down your infill speeds in the slicer... you maybe maxing out your hotend flow rate.

Especially PolyTerra has a pretty good flow rate when you heat it up enough. I usually print PLA with 230-250°C on my X1C.

Any tips for printing Polymaker Petg at faster speeds? I can get clean walls but I get bad stringing on infill and it sometimes goops up on the tip and looks burned

For starters, make sure it's dry and print from a drybox. Tune your retractions

Goops and burned could be a nozzle leak or filament strings/pieces stuck to the nozzle.

What's your current setup/settings?

One of the ways to print faster (assuming everything else is tuned) is just increasing your print temp.

You could also use a CHT nozzle, better hotend, etc

[formal tundra]

Way hotter, faster retract speed and higher retract distance, patience to learn the materials odd quirks.

Thank you both, I am printing on an ankermake M5 and I am brand new to 3D printing so this has been a huge learning curve. I did notice an improvement when I increased retraction distance to 6mm instead of default 3 I will also increase retraction speed

[formal tundra]

if your new honestly I would suggest to just take it slow and not rush yourself or your machine till you really know and understand it and your slicer.

[onyx knoll]

Which slicer are you using btw?

[gleaming bluff]

I've been bouncing between ankers slicer cura and prusa trying to decide what I like

Polyterra not god for high speed? that's weird, is one of the products with the highest melt index
