Polymaker Light Weight PLA Filament 1.75mm LW-PLA Grey 0.8kg Low Density 1.75mm - PolyLite 3D Printer Filament Grey, Print with Most 3D Printers

Must have a perfect level bed (it’s hard to get it to stick but once it’s dialed in I’ll go smooth)Clean bed with alcoholTemp-initial layer 210-layer 215Print slow!!!I print at 80% speedBest results if print one object at a time cuz it lives a lot of stringing

The important bits: layer bonding and strength is incredible! very rigid and much lighter than PLA or PLA+ but heavier than foaming lightweight PLA. I am going to use this on all my future 3D printed planes!Now my long boring story :)Patience was the key with this filament! I have seen too many great reviews to think that there was an issue with the filament itself. I took the recommended approach of printing using PLA settings and increasing the retraction distance and speed to the settings recommended on polymakers website.My prints were completely unusable initially. I didn't have a lot of time after work to run calibration tests but I did what I could in my free time. I would change one setting and print a part, I didn't write anything down and I didn't keep track of my changes. The poor print quality was completely my fault for not taking the proper time to dial in the print settings. I even tried multiple slicers!I finally had a day off! no chores, no work... time to get this right :)I started with the basics, e-step calibration and PID tuning. Those were very close to perfect already so I knew that wasn't my issue. I started back with the defualt PLA settings and did a retraction test (two 10mm cubes spaced 40mm apart). I would do a print and take a picture, record the settings and results and then make only 1 change to 1 setting at a time until I got the setting dialed in. Then I would move to the next setting. Rinse and repeat until I got everything dialed in. About 10 hours later, a nearly perfect print with just the smallest amount of stringing!Don't do what I did and just get frustrated and start throwing different settings at this stuff! It took the perfect mix of speed, temp, retraction speed & distance as well as extra prime after retraction to get this stuff dialed in. A change to any one of those setting will throw off the print!Cura 5.10Artillery Sidewinder X2 (love this printer!)Fulament magnetic flex PEI bedTemp 190Bed temp 60 (I always run 60 for everything, just seems to work)Print speed 40mm/sTravel speed 250mm/sRetraction 3.5mmRetraction Speed 35mm/sExtra prime after retraction .36mmMy issue was an extreme amount of stringing and oozing. I am printing a single walled print and it is important to have a strong Z seam. The loss of material during travel moves and layer changes made the Z seam very weak.

Never buying this Polymaker Wood / Lightweight PLA again. This stuff doesn't work. I've got 8 machines. They're all different brands and all different styles of printers. I have delta printers, core xy printers, and old school bed slingers. They all work. I keep em all tuned up and running juuuuuuust fine.For some really odd reason, this garbage is one of only a handful of filaments that won't print on ANY machine I own. Hotter, faster, colder, slower, thinner lines, thicker layers, thinner layers, thicker lines, different nozzles, larger nozzles, smaller nozzles, brass nozzles, stainless nozzles, tungsten nozzles, bed calibration after bed calibration, layer height adjustment, z off set adjustments up, z offset adjustments down.I am ashamed to admit how many hours ..... DAYS I wasted messing with this Polymaker Light Wood PLA. I finally threw (forcefully) what was left into the garbage can. NO THANK YOU ever again. People say "Never say never" I can promise you I will NEVERRRRRRR buy another roll of this stuff again.

prints great, once I figured out it wouldn't feed through my bowden tubes properly. printing on a Bambu A1,initially tried with the AMS, but had to switch to no bowden and an overhead spool, I have ordered some larger ID tube to see if that helps, but if its simply a friction issue, then I suppose I will have to suck it up.Would have been 5 stars otherwise.P.S... Polymaker support was awesome in helping out.P.P.S my plane is printed, but yet to fly.

This stuff is the real deal BUT:1. You have to take your time and dial it in on your printer. I did a lot of research online and got some idea of where to start with settings, but I still had to play and tweak them to get good results.2. You GOTTA PRINT SLOW. the parts will take time.3. No matter what you do you will have a some amount of stringing. Seam placement is vital and you can set it so the stringing is easily trimmed off.4. If you are doing airplane parts you have to know how to use Height modifiers in your slicer.If you take your time and really dial this stuff in you will get amazing parts, light, no layer lines, accurate. I'm totally impressed with this stuff.

You are going to need to dry this before using. Mine when I received it was not in a sealed bag. It was in a bag, but the bag had been punctured by something. Bought two spools, both were the same. Punctured bags.

Amazing!!! HIGHLY HIGHLY recommend joining their discord if you want the perfect settings

I used this for printing some RC aircraft parts and found that if you follow the instructions the filament performed as advertised. On my avg part I noticed a 20%-45% reduction in weight from standard PLA. One thing to note, this is ***Pre-Foamed***. I have read reviews were people were upset because it did not foam and they had to crank the temps up to get any foaming/expansion of the filament. It is not that type of LW-PLA. This prints better at lower temps, I found 190-195 to be the sweet spot for my parts. It is also not a smooth filament as it is pre-foamed it has a rough texture, to be expected.It prints great and with a nice smooth surface that is easily sanded where needed.
