Double the ultimate tensile strength of resin prints with electroplating. Vastly improve the stiffness as well!

In this video we electroplate SLA samples with Acid Copper and Bright Nickel, then test their tensile and ultimate strength using a universal testing machine. Stress measurements are done with a load cell and arduino, strain measuresments are done using Digital Image Correlation software DICe. Ultimate strength just about doubles, and stiffness improves dramatically for nickel coating.

PLA prints failed due to adhesion issues, so that will have to tested again in the future.

NOTE! Nickel allergies are common, and can develop at any time, so be careful if you play around with nickel plating and handle the prints afterwards. More info: https://en.wikipedia.org/wiki/Nickel_allergy
