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

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.

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

So this is my first time using this filament, I have used dozens of others in my print farm. I wanted to print a RC airplace and its doing a great job with a few issues. The settings I use worked on a couple of printers. Because it doesnt stick well onthe first layer I used 0.3mm first layers with a brim of at least 3mm. It get very stringy over 200C, in fact if its a small part you need to start at 190C and do the rest at 192C to get good layer bonding, and it does bond very well, but only with an extrusion multiplier of 1.15. I printed two of the same center wing parts, one in PLA+ and the other in this, the PLA weighed 18g and the LWPLA weighed 15g not a huge difference but enough. I also like the texture of the finished parts, it foams a little so you have a hard time seeing the print lines. One last thing, before printing the fillament is a little brittle, if your printer bends it around a small radius it will snap.

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

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.

For RC airplane building this stuff is the greatest. Not having to dial in the settings from the standard PLA settings and getting good results is a huge advantage.

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.

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.

Problème d'extrusion avec du filament bas de gamme, à éviter !!!!

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

lo he comprado por error, al confundirlo con el Polylight 1.0 LW-PLA de 3DLabPrint, y con este material las piezas pesan, por lo menos, 3 veces más y al ser preespumado, no se expande con la temperatura, así que además, también imprimes la mitad de piezas o incluso menos, ya que yo he estado imprimiendo con el Polilight a 44% de extrusión… Además este producto es mucho más caro y sólo viene con 800gr. en vez de 1 kg. Culpa mía por no haberme fijado bien… he tirado el dinero :(
