Ah, the cleanest surface finish ever! This stuff actively foams in the nozzle and changes weight with different print temperatures. There are two important parameters with this filament that affect the print quality, strength, and weight: temperature and flow. The higher the temperature, the more it will expand. This will make lighter prints with less strength. A colder temperature will print heavier but stronger. It’s a bit of a balancing act. Since the expansion at high temperatures will cover more ground with less filament, you’ll need to adjust the flow. A higher temperature will need less flow and a colder temperature will need more flow. Also there is NO RETRACTION with this filament so expect some clean up. You may need to experiment quite a bit before getting the results you want. Here is my profile with max foaming to get you started.
