Implementation Considerations

• Requires basic training in vector graphics software and laser cutter operation for mold design and fabrication.
• Depends on access to a laser cutter and vacuum degassing equipment for high-fidelity PDMS mold production.
• Necessitates standardization of PDMS mixing, degassing, and curing protocols across users to ensure mold consistency.
• Involves adaptation considerations when transferring molds to different culture dish formats or tissue types beyond cardiac constructs.
• Includes practical limitations such as minimum feature size (~25 μm) and mold degradation over repeated autoclaving cycles.
