Printing Guidelines
- Print Temperature: 215 – 225°C
- Bed Temperature: 40 – 80°C
- Bed Adhesion: Glue stick on glass, no additional adhesive needed on PEI sheeting or blue tape.
- Part cooling fan: Medium to high speed
- You will want to print FlexD a lot slower than stiffer filaments, you should start with a print speed of 15mm/s, you may be able to increase this value to around 25mm/s if you are printing hot enough.
- You will also want to have the retraction turned off, once you start having good extrusion results you may be able to introduce a small amount of retraction to clean up the surface quality but do so with caution, and only use minimal amounts.
