The Laser Ablation of Microparticle Aerosol (LAMA) process provides a method for generating high yields of aerosolized nanoparticles (NPs) that are then accelerated through a nozzle and impacted onto substrates. The process allows nanostructured films and patterned lines to be directly written onto substrates at room temperature. Using the LAMA process, we have demonstrated the ability to produce thick patterned deposits with densities ranging from 60–70% in the as-deposited state. After deposition, the lines were densified using pressure-assisted sintering and the microstructures and strengths of the films were investigated. Pressure-enhanced sintering resulted in densification and strong bonding at processing temperatures of 100–175°C and pressures of 100–600 MPa. Mechanisms for sintering at low temperatures are discussed.
