IP-PDMS
With IP-PDMS, soft, highly flexible, and elastic materials can be 3D printed by Two-Photon Polymerization (2PP). Its distinctive mechanical properties pave the way for innovative applications in microfluidics, life sciences, and MEMS.
Flexible material meets flexibility in design
The IP-PDMS photoresin is designed for applications that rely on elastomer-typical material properties: softness, flexibility, elasticity and biocompatibility. These characteristics pave the way for the photoresin to be used for a wide range of applications, such as 3D-printed cell scaffolds and tissue engineering, 3D-structured surfaces, microfluidic devices or microelectromechanical systems (MEMS). IP-PDMS is optimized for Nanoscribe systems.
- Highly elastic material with a Young’s modulus about three orders of magnitude lower than IP-S
- Low refractive index photoresin
- Non-cytotoxic according to ISO 10993-5 / USP 87
- Highly flexible material for a wide range of applications
Biocompatible elastomers
for life sciences
The silicone-based elastomer IP-PDMS shares the material properties for which conventional PDMS is known, but is developed specifically for the requirements of 2PP-based 3D printing. This makes IP-PDMS the optimal photoresin for the high-precision additive manufacturing of soft, flexible and elastic 3D microstructures.
Combined with its non-cytotoxic properties, tested according to ISO standards, IP-PDMS paves the way for new 3D-printed applications in life sciences and biology. The photoresin is beneficial for elastic freeform cell scaffolds or 3D designs mimicking the natural characteristics of soft tissue.

IP-PDMS, as a 3D printable material, is highly interesting for micropatterned functional surfaces. We can skip time-consuming molding steps to transfer designs into elastomers and new designs become feasible.
Mechanical properties drive new applications
With a Young’s modulus of 15.3 MPa, IP-PDMS features high flexibility and elastic properties. An evidence for the photoresin’s flexibility is its tensile elongation at break of more than 240 percent. The interplay of these mechanical characteristics paired with its low refractive index, chemical inertness and gas permeability are well-known for standard PDMS.
IP-PDMS promises novel applications and devices in life sciences, microfluidics and micromechanics. Thus, the design and manufacturing of microfluidics with freeform features and the realization of 3D-microstructured functional surfaces in one printing step become possible.
