What is E3D/PDMS?

E3D/PDMS refers to a combination of two technologies: Extrusion-based 3D printing (E3D) and Polydimethylsiloxane (PDMS). E3D printing is used to create three-dimensional structures by extruding materials layer by layer. PDMS is a widely used silicone-based polymer known for its biocompatibility, flexibility, and optical transparency. Combining these technologies typically involves E3D printing a mold or support structure, often using a sacrificial material, into which PDMS is then poured and cured. Once cured, the mold is removed, leaving a PDMS microfluidic device or other structure. This approach is commonly used in microfluidics, biomedical engineering, and soft robotics for creating channels, devices, and structures with precise geometries.
