<p>In this study, titanium samples with different yttrium (Y) contents were prepared by material extrusion forming process, and the macroscopic and microscopic properties of each sample group were characterized. It was found that adding a certain amount of Y can effectively improve the mechanical properties of the samples. The experimental results show that Y₂O₃ with stable structure and chemical properties can be formed during the sintering process. This effectively restricts the typical growth of Ti grains and the usual closure of pores, while also reducing the texture strength. In addition, due to the strong oxygen absorption ability of Y, the content of O within Ti is significantly reduced. By comparing the mechanical properties of the four groups of samples, it was found that the optimal mechanical properties were achieved when the Y content was 0.4 wt%, yielding a tensile strength of 574.3&#xa0;MPa and an elongation of 3.2%. This represents a 14.3% increase in tensile strength and a 100% increase in elongation compared to samples without Y. Utilizing material extrusion technology, this work improves the performance of pure titanium samples through Y addition, offering a new approach for producing high-performance titanium parts by additive manufacturing technology.</p>
