I just downloaded the Cessna 170 models, and am working through tuning the settings for my X1C. I ordered Polymaker's PLA-LITE thinking it was the filament used in the build video. Turns out, it was actually 3DLabs "PolyLight". Anyway, the filament is different enough that I'm having to re-work the settings. I've only printed a small section of the wing so far, and was having serious 1st layer issues. I seemed to have solved that by slowing down the 1st layer, but so far, I've only had a clean print by using a much lower temp. of 240c, and a flow of .85. Has anyone had experience with the Polymaker PLA-lite? I haven't printed an entire wing yet, so I don't know how my weight is going to compare, but I'm guessing it will be over the target. I'd also be interested to hear about experiences with BL Aero PLA, as I'm tempted to order a spool to try.
Thanks
I just ordered and printed the Cessna 170 parts. I am experienced with 3d printing but have never printed with lw-pla before. While I waited for my first roll of lw-pla to arrive, I printed the fuselage cowl, main fuselage and fuselage tail out of eSun PLA+ I already had. The three pieces weighed a total of 48g in eSun pla+. I then received SainSmart Light Weight Filament 1.75mm, LW-PLA Low-Density Active Foaming 3D Printer Filament (Amazon purchase) and printed the same three pieces again using the lw-pla. Zero print issues and the same parts out of the lw-pla weighed only 22g. I had set the flow rate to 53% and printed the lw-pla at 240C. Not one print issue. The parts are heavier than they could be if the flow rate was optimized I think but I was pleased the lw-pla weighed in at less than half of the eSun PLA+. The four-piece assembled wing weighed in at 35.1g in the Sainsmart lw-pla (at 53% flow rate which may be higher than necessary). The Cessna 170 has been a pleasure to build so far. I am printing with an Ender 5 using Cura 5.8.
Update: I finished the build using Sainsmart lw-pla and mine weighted 111g with the battery. This turned out too heavy as it couldn't gain any altitude flying straight and fell out of the sky upon an easy left turn. I used the 1106 motor and 1S ESC. The plane felt underpowered and it ultimately crashed and the main fuselage broke in half just behind the wing. I will try printing again with the flow rate tuned for optimally lighter printed parts as I think I should be able to trim 25% of the weight off the printed parts by adjusting the flow rate.
