Review on 🧵 Copper-Filled Silk Filament Printing Material by Jeremy Choi

LOWEST TEMPERATURE = Brilliant. This filament prints much shinier between 190°C and 200°C, although it says you can print up to 230°C. accidentally discovered that it turns dull gray as the temperature rises. You want to print at the lowest print temperature for the shiniest silver. (See photo) Please note that I did not measure the temperature at the nozzle with a multimeter, so it may differ slightly for your installation. Also, unlike other PLAs, this material is very sticky (will shrink on its own) so a bed temperature of 40°C wasn't enough, but 50°C didn't seem to make large prints warp at the edges. Glue sticks would also help. A high speed fan is essential for small prints. If you print a 1 inch test cube without a fan, you will see all the walls of the cube moving. The two cubes in photos 210 and 230 had a fan at 10% for the first half of the print and they look bad in that half. Cooling 100% took it away. In addition, the addition of a built-in filament dryer (Thordsen) eliminated small imperfections in each shift during troubleshooting.
