polymaker lw pla trailing edge problem

[badpilot27]

So recently I've been trying to use some polymaker lw pla that I've had for a couple years and I've noticed a lot of oozing on the trailing edge

I'm pretty sure it because the printer makes this weird loop near the trailing edge that the printer makes but I'm not sure how to fix it

I've tried making the walls thinner to 0.4mm (which is my nozzle size) but then orca slicer completely ignores them and only prints the thicker internal structure. this forced me to make the walls 0.48mm which makes the printer do 2 wall loops which i don't know how to fix.

I'm wondering if can get some recommendations on how i can change the slicer setting and/or the cad file to make this work better.

What 3D printer are you using? What Plane is this?
Can you post a link to where you got this plane so we can see what the recommended settings are from the designer.
Also, you said that this filament is a couple of years old, which might be a problem. Did you put the filament in a dryer to dry it completely before printing. Have you tried printing with a different filament to see if it helps.

I will try to print this part, but knowing where it came from would probably help.

I printed the part using Orca Slicer on my Ender 3 v2 printer and it seems to have come out ok. With some tweaking I think I could print it with a lot better quality. But this is not to bad considering it is LW-PLA, and defiantly flyable.
I printed this with PolyMaker PolyLite, I didn't try my Esun LW-Pla.
I am thinking there may be a problem with the Filament you are using. Maybe needs drying or maybe just old.

I'm printing on a bambu lab A1 btw

also i designed the wing to test out some slicer settings for lw pla so i do not know what setting are optimal.

yea the filament is pretty old (got it in 2021) and i have not dried it at all since because i don't have a filament drier (im getting one for Christmas though). i had to use a brim when printing because it would warp a lot with out it. also for some re

I had to use a brim when printing because it would warp a lot with out it. also for some reason the slicer does doesn't fully print out the first layer so I've also needed the brim to keep the wing from falling off the build plate mid print

also what's your slicer settings? I'm not too good with getting good slicer setting using yours can help me a lot.

This particular wing part that you designed is not hard to print.. I just used settings that I used for the Free 3DLabprint J-3 Cub plane

Bear in mind that some of these settings may be slightly different for you printer, as these settings are for an Ender 3 v2. In particular the speed settings my be different as well as some of the filament settings. Also, You really should load up some new regular PLA and try to print this wing to see what happens. The PolyLite doesn't require a reduced Flow like other LW-PLA does, and so regualr PLA should also print fine. I still think that your filament may be most of the problem. If the parts are not sticking to your bed, then you probably need to be using glue stick, which is what I believe Bambu recommends. There is no Brim or Skirt settings here so if you need or want them you will have to set that. Also, make sure that Supports is turned off, you don't need supports for printing most RC plane parts.

That said, Here are the Orca Settings I used .

Was wondering if you tried any of my settings. Did you ever get this to print.??

yeah i printed it today and it was perfect

first attempt failed as the print came off the print bed (this lw pla has some bed adhesion problems with the stock pei plate with no glue)

second attempt I used a brim which got it to stay on the print bed

thanks for the help

No problem, glad it worked. Glue stick will definitely help LW-PLA to stick.

Yeah I'm probably going to get the bambu cool plate super tack later which I think would help a lot
