POLYMAKERLight Weight PLA Filament 1.75mm LW-PLA Grey 0.8kg Low Density 3D Printing Filament, PolyLite 3D Printer Filament Grey, 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 5.10Artillery 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.

Ran some tests and overall it printed fine on a P1P but bumped temps up about 5 degrees above stated max temp….standard speeds default on the Bambu.Printed several test parts in PLA plus and this PLA lightweight and weighed on a postal scale. The difference was 33% lighter which is fine for my needs. Will see how the durability is as the walls were just a bit more flexible but not feeling like we’re brittle or anything but time will tell

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.

prints nice and is light weight but the winding job on the spool leaves little to be desired. keeps getting stuck and quits printing in the middle of the print and its wasted. that's why I give it 1 star.

This filament is pre-foamed! If you are printing an eclipson model plane, their recommended settings will not work. I almost returned this filament but eventually got it going after much trial and error.Obviously settings will change based on your printer, but I figured I’d share what I changed vs Eclipsons guide. Here were my findings for a V1 Ender 3 with a steel nozzle.Nozzle: 208Bed: 60Flow: 139Retraction: 3.5I followed all the other eclipson recommendations.I really had to jack up the flow rate to get it to flow smooth. It prints nicely, marginally heavier than ColorFabb. It appears to be very strong as well.I do have some issues with stringing during travel, and it appears to be just a part of this filament. I brought retraction back even further, but was seeing some issues with incomplete extrusion right after it begins printing after travel.

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.

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.

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