NYC Resistor members recently spent an evening playing around with resin:
For today’s #hackfriday at NYC Resistor a bunch of us were inspired by Junior and ScribbleJ‘s 3D printing projects and experimented with UV curing resin using a DLP projector.
We had some JMP UV stamp resin, although it didn’t cure solid with the normal projected image in our test. Even with thirty minutes of exposure, the resin was unchanged in viscosity.
As a next step, we removed the DLP’s mercury arc lamp and drove it positioned just a few cm directly over the resin.
With the interlock defeated and proper safety precautions, the result was a very quickly cured puck of resin. Which is good news, since it means that there is enough light intensity around 380 nm.
