| Abstract Scope |
A novel additive manufacturing technique called High-Velocity Laser Accelerated Deposition (HVLAD) where thin films of material are bonded together layer-by-layer using a high intensity laser is reported. This method is a non-fusion-based technique and does not rely on the thermal effects of laser, rather it uses its mechanical effects similar to the laser peening process. The laser beam is used to generate a pressure wave to accelerate the films, layer-by-layer, with a high velocity towards a substrate to create a bond. This process is repeated until a desired thickness, or a three-dimensional object is created. Nanomechanical characterization techniques are used to evaluate the mechanical properties of the deposited material as well as the substrate. Scanning electron microscopy is used to investigate the microstructure. A correlation is drawn between the microstructure and mechanical properties. The HVLAD method is capable of depositing a wide range of materials. |
