PDMS Master Molds

We design and manufacture high-precision master molds for PDMS microfluidic devices using Master Mold for PDMS resin and state-of-the art microfluidic 3D printing technology. Our molds are compatible with standard PDMS casting workflows and replace traditional SU-8 photolithography tooling for many applications.

The process delivers a precise high-quality surface finish with an RA value of ~0.18µm and a drastically reduced meniscus effect for sharp and ultra-precise features.

These 3D printed PDMS Master Molds are suitable for repeated replications, provide a long mold life and are compatible with PDMS without release agents or additional surface coating.
PDMS can be poured directly into the mold and cured in a lab oven at 100°C (212°F).

PDMS master molds are well suited for applications requiring gas permeability, elastic deformation, or biological compatibility.
This method significantly reduces turnaround time and lowers barriers for labs without cleanroom access.

 

Typical use cases:

​

  • Cell culture microfluidics

  • Gas-permeable devices

  • Academic research labs

  • Early-stage microfluidic startups

  • Iterative design validation

  • Small batch PDMS production

 

We offer a range of standard PDMS master molds for various applications in our Online-Shop.
