Abstract Scope |
Glass-wire laser direct energy deposition is an additive manufacturing process that uses a laser to melt glass filaments or fiber optic into a glass structure. Unlike metal deposition processes, the large thermal working range for glasses enables unique capabilities in printing, including printing completely unsupported spans such as in spring and truss structures. Glass AM has been used to print functional structures including lenses, glass-to-metal seals, fiber optic devices, and microfluidic systems, as well artistic structures. One challenge in Glass AM is effective and repeatable control of bonding and geometry during initiation and termination of the wire print. This is particularly critical when occurring in the middle of a build, as can frequently occur for most glass wires that cannot be spooled. Wire feed and laser power process parameters and wire preparation strategies will be explored for repeatable initiation and termination of the print. |
