Flexible (rubber like) TPU Filament - 1.75mm - Black - 600g Spool

Adheres well on most surfaces, even on glass. Tested on Blue tape and straight on glass (both cold) with excellet adhesion.
Extrusion molding grade; with special UV stabilizers; very good hydrolysis and microbial resistance; good low-temperature flexibility;

- Will spiderweb, so choose model well.
- Turn filament fan off during early layers, then print like you would PLA.
- We recommend raising the print temp. slightly compared to regular PLA and reduce the print speed to around 40mm/s to help the filament to just fall out of the nozzle rather than be pushed by the feeder
- Melting Point 190-250 °C

We have printed a lot with this material on the Flashforge Dreamer. Settings and info you may find helpful:
Bed Temp: We heat the bed to 50 degrees, unless twin extruding with ABS see below.
Resolution : 200 - 300 micron
Print Speed: 30 mm/second
Temperature: 230 degrees
Nozzle fan: ON (we use the left extruder on the dreamer and tell the default it is PLA so this turns on.
Two Materials: We have printed Flex-PLA and Flex-ABS Both stick/fuse well together. In both cases we use the plastic as the raft. With ABS we raise the bed temp to 110, however also found the higher heat did effect print quality of the flex (perhaps as the filament fan is also turned off).

General Note: Flex is very susceptible to stringy webs between walls (called spider webbing). Reducing temperature defiantly helps, as does slowing print speed. It is interesting that in the heated chamber of ABS printing this is much less, but the quality of the overall flex print is also more poor.
