Polymaker Light Weight PLA Filament 1.75mm Grey 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.

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.

Works great prints very well on my creality ender 3 s1 pro. Prints seem to be strong and very light. I am printing parts for a R/C airplane. I bought a second spool because i really liked how well it works

This filament is amazing. Drop it in, print with your normal settings and your prints are lighter. The filament is STRONG!! I have printed a number of rockets with a .6 nozzle in vase mode and a blow to the print with hammer wont break it! This stuff will be amazing for some of my upcoming drones and other RC aircraft. The filament bonds extremely well for each layer. I've tried the grey and the black but the black is beautiful. The filament has almost a texture to it when printing so your prints may need some sanding for a smooth finish but the filament sands wonderfully. This filament was used to win a regional 4H Aerospace competition and will be going to the state finals. Thanks Polymaker for making some great filament.

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.

Works great highly recommend. I use it to make RC Planes. You have to play with it for a bit to get your settings right. What i did on my bamboo p1s I put it as regular PLA setting and it did great.

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.

So far so good! It really does print with my standard PLA settings.

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.

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.

Iam a Rc plane enthusiast ,few days back I bought this filament for less than 3500 / 800 grams . Now the price is very high. Please encourage RC hobbists by offering with minimal margins so that more people will use your product. Quality: Good quality Price : very High

Ne tient pas ses promesses. Il est facile à imprimer mais question poids on gagne environ 25pc par rapport à un pla normal et non 50 pc . J'avais acheté celui-ci pour imprimer un avion rc. Un pla lw (e sun par exemple) est beaucoup plus léger. A déconseiller pour la réalisation de pièces qui doivent être légères.

I had two spools that printed no problem, but two spools that were packed too tight causing binding and causing the print to fail. I really like the filament when it works, but the fail issue is terrible. The texture is gritty so it is more likely to get stuck. The sticking is only due to it being compressed against the roll walls, nothing to do with the printer.
