摘要： Methods of creating golf club components with complex structures that would be difficult, impossible, or cost prohibitive to produce, such as lattice structures, beam structures, and complex surface-based structures, are described herein. In particular, a binder jet machine is used create complex structures to optimize weighting, sound, and performance of golf club heads. The method preferably includes the steps of designing a golf club head component in CAD using optimization software, printing the component from a powdered material, and then removing excess powder from the component via port holes that extend into an external surface of the component and communicate with interior voids within the component.

摘要： Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer is formed between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering.

摘要： A method for the manufacture of a three-dimensional object using a refractory matrix material is provided. The method includes the additive manufacture of a green body from a powder-based refractory matrix material followed by densification via chemical vapor infiltration (CVI). The refractory matrix material can be a refractory ceramic (e.g., silicon carbide, zirconium carbide, or graphite) or a refractory metal (e.g., molybdenum or tungsten). In one embodiment, the matrix material is deposited according to a binder-jet printing process to produce a green body having a complex geometry. The CVI process increases its density, provides a hermetic seal, and yields an object with mechanical integrity. The residual binder content dissociates and is removed from the green body prior to the start of the CVI process as temperatures increase in the CVI reactor. The CVI process selective deposits a fully dense coating on all internal and external surfaces of the finished object.

摘要： Ti ink compositions for printing, such as ink jet printing, are disclosed. The ink compositions comprise a liquid dispersion of Ti hydride powder having a mean particle size of less than 10.0 microns; a liquid carrier, and at least one surfactant. Methods of making and using the disclosed inks are also disclosed. For example, a finished Ti product can be produced by printing the disclosed ink composition, such as by ink jet printing, to form a green article, heating the green article to dehydrogenate it and form a Ti containing part. The method may further comprise sintering the Ti containing part to produce a sintered Ti product. In an embodiment, the method comprises printing one or more support materials for the ink composition, that comprises solid particles of a metal oxide, a metal carbide, a metal nitride, a polymer, or combinations thereof.
