Review on Polymaker 1.75mm Cardboard Filament for Printers by Gerald Reeves

I bought 2 rolls of this material mainly for the fiber roll. I don't like tossing empty 200gram plastic rolls in the bin and it appealed to that part of me. Now for the pros and cons of this thread: Cons: Deformation! this is bad. I tried changing the nozzle temp, 3 different prints, 3 different hot ends, 2 different size nozzles, PEI. Building panels of plastic. Cup. tape on glass. tape on glass. Cleaning with methanol before printing. Sand/then clean bed, sand/clean/tape. Head deceleration up to 35mm/s. rise in bed temperature. drop in temp beds. Increase/decrease in consumption. Silicone cover on/off nozzle, everything. The larger the part in the Z direction, the more out of specification it is. Cons: Tension. This is bad. not bad, but this part requires significantly more cleanup than other threads I've used in the past. Pros: Great matte texture. Details look nice (when printed). Other thoughts (no manufacturer fault): The natural fiber spool turned out to be more of a problem than I thought. Because I print my own spool holders, the surfaces of my spool holders (which include a printed sleeve bearing) are less slippery than other holders, causing the spool to stick strongly to my spool holder (natural fiber is not "slippery" and neither is my spool holder ). I haven't had this problem with plastic spools, but that's the problem. Again, this isn't the manufacturer's fault, but should be considered if you have a similar setup. Summary: I bought 2 rolls. I really liked the texture but probably came out with about 400 grams of detail from 2000 grams considering all the flaws and waste.
