Additively manufactured elliptical bifurcating torsion spring

An additive manufacturing method for 3D printing an elliptical bifurcating torsion flexure device comprising:

• printing a base section;
• printing a bifurcated legs section on said base;
• printing a bifurcated elliptical torsion spring section contiguous with said bifurcated legs section;
• and
• printing a single upper section contiguous with said elliptical torsion spring section on a first end, said single upper section comprising a connection component on an opposing end;
• wherein the base section, bifurcated legs section, bifurcated elliptical torsion spring section, single upper section and connection component are printed as one part by said 3D printing additive manufacturing process;
• and
• wherein said bifurcation maintains consistent balance while being torqued.

A 3D additively manufactured elliptical bifurcating torsion flexure assembly system comprising:

• a base section;
• eight elliptical bifurcating torsion springs, each comprising:
• a bifurcated legs section supported by said base;
• a bifurcated elliptical torsion spring section contiguous with said bifurcated legs section;
• and
• a single upper section contiguous with said elliptical torsion spring section, said single upper section comprising a connection component;
• wherein a material of said device comprises Hot Isostatic Pressing (HIP) heat-treated Ti6Al4V;
• wherein a diameter of said base section is approximately 2.5 inches;
• wherein a height of spring flexure elements is approximately 2.5 inches;
• wherein a cross sectional diameter of said elliptical torsion spring section is 0.08 to 0.25 inches;
• wherein a cross sectional diameter of said bifurcated legs section is 0.08 to 0.25 inches;
• wherein a cross sectional diameter of said single upper section is 0.08 to 0.25 inches;
• wherein said elliptical bifurcating torsion flexure assembly is printed as one part by a 3D additive manufacturing process;
• and
• wherein said bifurcation maintains consistent balance while being torqued.
