Crystal Heart

This one is intended for Isabel as a housewarming gift. She requested something with an anatomically correct heart.

Printed with 0.025 mm layer step size using clear resin v2. Inside is filled afterwards with the same resin+acyrlic paint, then cured under the sun. When the model is this small, I think 0.025 mm layer step size tends to work better, due the strain capability of thinner walls. On bigger models, I had more success with 0.05. I think this is due to a competition between the build platform and the tank itself (my theory: since cure time of epoxy is a probabilistic process, there will be some that will be in a “about to be cured” sticky state after the build platform leaves, if the gradient is too small, these particles will be cured with the next laser, but will stick on the tank). The outer layer is finished with detail enhancing acrylic paint intended for plastic models. The shell is an ikea frame modified with some cutting and sticking. Background is an image of veins from a medical book.

I really like how the fine detail came out.

I also made another version with EL light tucked inside instead of pigment. The EL light pulses synchronized to a heartbeat rhythm.
