Jetting materials for binder

Three options are available for the jetting resin, or binder for different purposes.

ZD-16, PEGDA, HDDA, PEGDA (from the left)

ZD-16 is clear binder, PEGDA, and HDDA are UV curable resin.

Carbon fiber 3D printer test run.

I still need to adjust the UV lamp location.

The inkjet nozzles were not jetting sufficient resin to bind the power. Double sweeping with higher density can improve the part. I will try again with different setting this week.

Test run on a paper

The cartridge is successfully hacked and the resin is printable through the nozzle.

The first printed parts using binder ZD-16.

The post process was required in order to hold the shape stronger. When I left the cartridge at the lab, the surface of the nozzles were clogged from the surface of the nozzle. The resin, and binder are still printable, however I need to make anti-clogging system such as having a cover lid for the nozzles that can prevent from curing the nozzles and clogging while they are not being used. After I install more UV lamp, the printed part using UV curable resin will be stronger than the one used ZD-16 binder.
