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. Printing with glass generally requires control of the wire orientation as well as direction to achieve consistent bead geometry. However, coordination of the orientation with the linear motion can be challenging, particularly around corners. This poster presents a method of coordinating the rotational axis with linear axes during print to reduce geometric defects when the print changes direction. Interpolation algorithms and parameter optimization results will be presented. |
