Experimental evaluation demonstrates enhanced print resolution and throughput in aerosol jet printing, indicating viable scaling for flexible hybrid electronics.
Key Points
Modulating droplet evaporation via an in-line heater decouples deposition rate from liquid volume, which enables narrow features with aspect ratios up to 0.29.
Printhead heating to 80 °C reduces resolution sensitivity by approximately 90%, which stabilizes aerosol jet printing across variable operational speeds.
Assessment using in-line heating to control droplet drying enables conformal patterning on rough surfaces, supporting rapid design of flexible electronics.
