Abstract: A titanium-tantalum alloy having a titanium wt % ranging from 10% to 70% and wherein the titanium has a body centered cubic structure. A method of forming a titanium-tantalum alloy, the method comprising the steps of: (a) slicing a 3D CAD model of a part to be formed into a plurality of 2D image layers; (b) preparing a homogenous powder mixture of titanium powder and tantalum powder; (c) dispensing a layer of the powder mixture onto a processing bed; (d) performing powder bed fusion of the layer of the powder mixture according to one of the 2D image layers in one of: a vacuum environment and an inert gas environment; and performing steps (c) and (d) for each of the plurality of 2D image layers in succession.

Abstract: A hydrogel composite is provided. The hydrogel composite comprises a modified poloxamer having a first charge moiety and a peptide having a second charge moiety, wherein the first charge moiety and the second charge moiety are oppositely charged for ionic interaction between the modified poloxamer and the peptide, and wherein at least one of the modified poloxamer and the peptide comprises a crosslinkable moiety. In particular, the modified poloxamer is a pluronic monocarboxylate activated by dimethylaminopyridine and triethanolamine; the peptide is a gelatin methacrylate. A bioshaping method using the hydrogel composite is provided, as well as a three-dimensional network obtained by the bioshaping method.
