Abstract

It is a rapid prototyping and manufacturing process that deposits metals and ceramics by local heating of a substrate with a laser. Laser Chemical Liquid Deposition (LCLD) process planning requires new efforts due to its unique characteristics. Based on LCLD system powered with a 50 W Fibers-laser, a set of experiments performed was described. The morphologies of the metals deposits were studied while varying laser power, chemical liquid reagent concentration, scanning speeds and scanning patterns, and explore process issues in using LCLD to create multi-layer metals structures were addressed. Through studies of the LCLD process, the unique deposit characteristics were identified. The spatial resolution is potentially very fine, depending on the accuracy of stage or laser movement, and the size of the laser spot used for the localized heating. Multi-layered structures require an understanding of interlayer adhesion and the propagation of geometric anomalies through multiple layers. It can build conformal layers (conform to non-planar substrates) and thin walls. Current research efforts focus on the creation of more advanced three-dimensional metals objects through the use of multi-layered deposition.
