Has anyone already experimented with mixing high temperature resin?
The material is far too brittle for us. Our temperature requirements are only 150 Celsius maximum so I thought about mixing the resin with more flexible resins to lower the maximum temperature and increase flexibility.
I’ve tested clear and rigid resin at 150C already. Clear is very flexible at that temperature and Rigid is doing a good job, however it is prone to cracking when there is a little bit of stress due to other components in the assembly.
I’m now printing several mixtures (50/50 and 80/20):
High temp + Clear
High temp + Rigid
High temp + Durable
High temp + Black
The clear and durable 50/50 are most interesting so far, still having a bit of flex at 150C and not being brittle as pure HT resin. but it’s very preliminary. I’m going to print a lot of tensile bars and test them on a force bench on elevated temperatures.
If anyone experimented with this, please let me know!
