▌ Notice
F39/F69/F39T flexible resin prints will harden at low temperatures (below 20°C). It is recommended that the prints be used in an environment above 25℃
If you need prints to remain soft below 20℃, please choose F80 resin.
F69 is a black flexible resin.It has excellent tear strength and elongation at break, and the texture is similar to rubber.

▌ The difference between F39, F69 and F80
- Color:F39 is white, F69 is black, F80 is gum color
- Elasticity: F80 > F39 = F69 = F39T
- Tear strength: F80＜F39 = F69 = F39T
- F80 prints can remain soft at low temperatures, others will become hard
