Polymaker LW-PLA 3D Printing Filament 1.75mm, 0.8kg, Grey

Works great but you need to have the settings correct of printer. I ended up at 210 which seemed to work well.

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 5.10 Artillery Sidewinder X2 (love this printer!) Fulament magnetic flex PEI bed Temp 190 Bed temp 60 (I always run 60 for everything, just seems to work) Print speed 40mm/s Travel speed 250mm/s Retraction 3.5mm Retraction Speed 35mm/s Extra prime after retraction .36mm My 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.

This stuff prints great. Just like regular PLA except with a little post cleanup required. However, it must be noted that if you’re trying to print RC planes, this is NOT the active foaming LW PLA that many RC planes are supposed to be printed out of. That being said, this pre foamed filament will likely still work, just a bit heavier and more expensive. Way easier to print though.

This is a good light weight plastic, but printing can be a bit fussy. Read the package. It must print slowly - 50 mm/sec max. Slow the travel and acceleration times, too, so you don't knock things around too much. If you print at normal PLA speeds - up to 200 or 300 mm.sec you'll get a mess. It prints at 210C not the 230C that other foam PLA's print. I had some problems getting it to adhere to the bed - an issue for tall wing sections. I used a raft to get good surface contact with the bed. Otherwise it does a great job of printing model wings, ailerons, etc.

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.

I had regular black pla and it worked wonders. But this one just kept on getting messed up on my Adventure 5M 3d printer. And i tried default settings and adjusted settings suitable to this pre-foamed LW pla. But this product just sucks cant wait to return it.

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.

Active foaming PLA is vastly superior. Ironically, the BambuLab PLA-AERO required less tuning and is less finicky. It is more expensive, but also significantly lighter. Just stick to that. This stuff is incredibly finicky and frustrating to work with.

Les températures d'impression ne sont marquées que sur la boite : reportez les sur la bobine pour ne pas oublier. Le fil est '' rèche '', pas lisse avant impression. La bobine fait 800g pas 1kg, comme prévu.

I always buy from this seller because of the Great quality fast shipping and awesome customer service. Highly recommended

This filament is terrible to print with. It doesn't stick to anything, has to be printed extremely slow, has massive stringing issues, is brittle, and doesn't really feel like wood. The color is also kind of ugly and makes your parts look like they are made of MDF instead of actual wood. It is also over double the price of normal PLA. Avoid the headache and don't buy this filament.

I didn't experience any issues LW stand for my DJI Mini 3 Pro

Polymaker LW filament is top-notch. I use it with a dryer, printing at 50 mm/s, 750 mm/s² acceleration, and 210°C. Taking it slow pays off—prints come out super clean with amazing detail and great adhesion.
