Paragraph starter

The selection of Ti-42Nb alloy for additive manufacturing of implants is supported by research indicating its favorable mechanical properties. Studies have shown that SLM-printed Ti-42Nb exhibits a Young's modulus of approximately 60.5 GPa and a tensile strength of 683 MPa, with a compressive strength of 1330 MPa. This combination of high strength and a relatively low elastic modulus makes it a promising material for reducing stress-shielding effects in orthopedic and dental applications, while its powder form is well-suited for patient-specific implant fabrication via 3D printing.
