From Prototype to Scalable Microfluidic Manufacturing
Microfluidic prototyping validates flow behavior, microchannel geometry and device functionality before investment in production tooling. It allows engineering teams to identify design and material issues while changes are still fast and cost-effective.
Micromolds develops functional microfluidic prototypes with manufacturing in mind, aligning geometry, materials and process requirements with the intended production method. We support early-stage PDMS validation as well as thermoplastic prototypes for projects progressing toward injection molding and serial production.
Why Microfluidic Prototyping Matters
Reduce Risk Before Production
Validate microchannel geometry, flow behavior and critical device functions before committing to production tooling.
✓ Validate microchannel geometry and flow behavior
✓ Identify design limitations early
✓ Reduce costly tooling changes
✓ Confirm compatibility with the intended manufacturing process
Accelerate Development Cycles
✓ Rapid design iteration
✓ Functional testing before tooling
✓ Faster transition from development to production
✓ Reduced development risk
Design for Manufacturing (DFM)
Prototype decisions should support the intended production process rather than validate only laboratory performance.
✓ Evaluate moldability
✓ Review critical micro-scale tolerances
✓ Consider production materials
✓ Align geometry with tooling requirements
Microfluidic Prototyping Capabilities
Our prototyping workflow supports functional validation and manufacturing readiness.
Capabilities:
✓ Microchannel geometry replication
✓ Fluid flow validation and droplet generation testing
✓ Surface interaction and fluid routing evaluation
✓ Bonding integrity verification
✓ Material compatibility testing
✓ Evaluation of manufacturing tolerances
PDMS Prototyping for Early-Stage Validation
PDMS prototyping enables rapid validation of microfluidic concepts during early development, making it useful for testing flow behavior, droplet generation and initial device functionality before production materials and processes are finalized.
Applications:
✓ Flow testing and visualization
✓ Droplet generation experiments
✓ Rapid design iteration
✓ Early-stage functional validation
Limitations:
✓ Not intended for high-volume production
✓ Material properties differ from thermoplastics
✓ Limited scalability to industrial manufacturing
Thermoplastic Prototyping for Production Readiness
For microfluidic devices intended for injection molding, thermoplastic prototyping provides more production-representative validation than PDMS alone. It allows engineers to evaluate device geometry, material behavior, tolerances and assembly using materials closer to those intended for serial production.
Materials:
-
COC / COP
-
PMMA
-
PC
-
ABS (application dependent)
Advantages:
✓ Closer to final production materials
✓ More representative dimensional validation
✓ Evaluation of production-relevant tolerances
✓ Suitable for pre-production functional testing
✓ Better preparation for tooling and injection molding
