Polymaker Light Weight PLA Filament 1.75mm Black 0.8kg, Low Density PLA

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.

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

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 alcohol Temp -initial layer 210 -layer 215 Print slow!!! I print at 80% speed Best results if print one object at a time cuz it lives a lot of stringing

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 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.

While it does have some positive aspects, I encountered significant issues that outweighed the benefits. Here's a breakdown of my experience: Pros: Very strong for a lightweight PLA: The filament boasts impressive strength despite its lightweight nature. It produces sturdy prints that can withstand some stress. Really nice color and matte finish from the filament. Cons: Constant clogging on multiple printers: The most significant drawback I encountered with this filament was the constant clogging issue. It became a frustrating experience as the filament would clog randomly, either within 15 minutes of printing or after as long as 20 hours. This inconsistency made it difficult to complete successful prints. Random distortion and clogging: The filament showed signs of random distortion in certain sections, which eventually led to clogs. It seemed like there might be some foreign material embedded within the filament itself, as unclogging the nozzles became nearly impossible without resorting to extreme measures like using a torch. Wasted spool on failed prints: Unfortunately, due to the frequent clogging, I ended up wasting a almost all of the spool on failed prints.

This is the Polymaker prefoamed lw-pla. It is slightly heavier than eSun lw-pla, but still extremely lightweight. The reason I love it so much is because it is so much easier to use than regular lw-pla. Basically I used regular pla settings in Cura. The photos are from the new Eclipson GO 1 WOLF plane that is free to print on the Eclipson website. The prints are strong, smooth, and zero stringing! There is not as much material on a spool since it is already prefoamed, but the price is in line with other lw-pla for the amount you get. I totally love it and will be purchasing again for future builds!

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

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.

I gave up trying to get a decent part using this filament. It adhered poorly to the bed, and had a lot of strings, worse than PETG. The surface finish was not nice; rough, not smooth. The parts came out under extruded so I had to increase flow rate, totally loosing any weight benefit of this pre-foamed filament. I have had such great experience with other filaments it doesn't make sense wasting time with this stuff.
