MicroScale Mechanical Testing Examples

Mechanical Testing of Soft Gels

Hydrogel MicroSphere Compression Test Demonstration

Our lab focuses on micro and nanoscale 3D-printing of soft hydrogels for tissue engineering applications. The MicroTester is a unique device capable of accurately testing our 3D-printed scaffolds where other methods have fallen short. The software provided is easy to use and provides flexibility for the diverse needs of our lab
