  1. Good thought, but to my knowledge this shouldn't be the case. Maybe it could be water if the filament acutally absorbed moisture, I tried drying it yesterday for 1 hour at 100°C, but the printing results were the same... Maybe i have to dry it longer, but i guess my best option is to make filament with a consistent diameter. I will try heating the filament outside of the nozzle, maybe I get some useful information out of it. The purpose of printing it is a pharmaceutical application.
  2. Thank you for your answers! My filament is ethyl cellulose, a cellulose ether. It is pretty hydrophobic and should not absorb moisture that easily, but i will give it a try. Since i only got a few meters left the drying-process shouldn't take that long. When printing i also noticed that the extruded filament shows something like air-inclusions. Some extruded lines have more inclusions, some have less. Is this linked to the wrong temperature or could it also be connected with some water absorption?
  3. The printing quality with normal fimalent is just fine, I tried the same tower with ABS. I just don't understand why the first lines are pretty good quality with the self-made filament when the inconsistent diameter is problem for the bad quality.
  4. Hi, I was trying to print some self-made filamet but experienced some problems improving the printing quality. The filament is not ideal since it doesn't have a consistent diameter which is probably the main reason for an inconsistent extrusion. I was trying some different temperature settings and also a temperature calibration tower. The problem is that i have to find a good starting temperature for the first layer so i can try different temperatures in one printing session, otherwise the first layer of the temperature tower is seperating from the heatplate and the layers do not stick together. The thing i don't understand is why the outer lines of the brim i was printing have "good" quality and after 3-4 lines the quality rapidly declines (See picture). Anyone experienced similar results when printing ? What is the reason for that? Can i change my printing settings to have the quality of the first 3-4 lines for my whole printing process? I was thinking that maybe the filament for the first lines remains longer in the nozzle during the heating process which is the reason for the improved quality? Thank you in advance for your answers
