OVERTURE PC Professional Filament, Cardboard Spool, 1kg(2.2lbs), Dimensional Accuracy Probability +/- 0.02mm, Fit Most FDM Printer (Black)

This PC filament was easy to work with on my Bambu Labs X1 Carbon. Using the stock settings from Bambu worked well enough to begin with. But it gets even better once calibrated. Once I got the flow ration and pressure advance dialed in, I tested the max flow rate, and it achieved 26mm^3/s with a stock 0.4mm nozzle. I dialed it back to 24mm^3/s and have been doing some non-stop printing since. I haven't had issues with adhesion or warping. I print without brims or rafts, using a smooth PEI plate with the thinnest glue (mix of glue stick, water and alcohol) as a barrier/adhesion booster. I'm not seeing any issues with warping, and my prints come out immaculate.The only draw back is the cardboard spool as used in the AMS. Which is why I'm using the filament to create a re-spooler so I can use this same stuff over and over again. I can't wait to grab more filament.

The title in the listing is very misleading. It is not PC (polycarbonate). It's actually PCL (polycaprolactone).Unlike the general toughness of PC, PCL cannot handle continuous stress or bending. PCL is also about as brittle as PETG but handles higher temperatures. However, PCL is nowhere near as safe or practical as PETG (see below).As much as I wanted to like Overture's PCL, in the end I realized that it's just a terrible idea. It's mildly stringy no matter the temperature, speed, or retraction settings I've used. While I could easily remedy the stringiness with a few passes using a low temperature torch, there's just no getting around the random bible-like artifacts that the Clear filament produces which ruin every print, even after placing the spool in a heated filament dryer for 3 days. It also easily deforms when making small parts under 1.5-inches, even when the temperature/speed is set to Overture's specified lower range. I found that using a moderate amount of active cooling produced smoother outer walls, but would definitely not work on larger parts due to warping. Last but not least, it produces toxic fumes which caused my eyes, nose and skin to become irritated. That alone is the only reason I need to send it back.I mostly print ASA, ABS, PETG and sometimes real PC and none of them have made me sick like this PCL stuff. So besides ruining one's health, the filament is just not practical in any way, shape or form. It's also very expensive and way too finicky when printing it, and there's really no way to justify buying it when one considers all the other options out there.

This is a good PC filament. PC in general can be tricky to print but I use PC filament a lot and I have used most all of the brands out there and this is one of my favorites. It prints well has decent bed adhesion for PC and is very strong.Really I have no complaints on this Overture Tough PC filament, it's great. The part in my pic is very small and this filament still has great quality for PC and the detail of the small parts are very good.

Needed something that could withstand 200f without losing strength. This does. Still maintained strength at 200f in the oven, long after my PETG part melted.Seems very brittle and would probably print better at 260-270, but my printer can't go over 250 :(Does break along layer line seams when it fractures, but still pretty strong.Again.... probably 260-270 is optimal and would hold layer lines better.

Polycarbonate is one of the most difficult filaments to print and if you don't have the correct checklist of prerequisites before printing its never going to come out the way you want it toi use a bambu X1C and have made well over 10 very large prints with polycarbonate to fantastic resultsperfect layer adhesion fine detailing and extremely toughmy only gripe is that since the material is so tough breaking off supports can be super tedious but you get tedious with most filamentshonestly overkill for most projects but if you need something very strong to print with and nothing else will do this is your best bet
