Thought id post about our recent success in incorporating doped graphene nano platelets into sla resin on our form 2.
We have been researching graphene for the past two years making our own, today we were able to incorporate it into black v4 resin at a ratio of 1%.
From the first tests the loading of 1% was too high, I suspect you only need about 1 gram per litre also we used black resin but we wanted to see the effect on dispersion with the hardest to cure resin (in our experience). In our test we used 100ml and a 1ml of additional photoinitiator. Should also note that we had to cure with open mode set on castable as our machine has a weak laser.
Shall be trying HT soon at lower percentages. Will be interesting to see the strength and temperature performance increase.
We used ultrasound to disperse the particles. Ours is quite expensive but I’m sure a bath sonicator would also work, just take longer and heat would need to be monitored.
If anyone is interested in trying let us know, would be interesting to see others getting involved in having a go.
Cant post the videos there too large but if you wanna see let me know.
