This is primarily because previous research has focused predominantly on maximizing relative density while paying relatively less attention to minimizing surface defects, including coarse surface topography and subsurface defects such as shallow pits and notches.<\/p>\n\n\n\n<p>After this experiment, it was concluded: only by high-quality Ti-6Al-4V powder, the printed parts can be manufactured with full density and minimal surface defects to get satisfactory mechanical properties. This is because residual internal porosity and rough surface topography significantly impact mechanical properties even after post-processing.<\/p>\n\n\n\n<p>Besides powder properties, scan pitch also is a critical parameter related to defect generation. A reasonable scan pitch that ensures sufficient overlap between scan tracks and layers can minimize surface defects such as high roughness, large voids, and sharp notches.&nbsp;<\/p>\n\n\n\n<p><strong>Recommended Process Optimization:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"496\" height=\"637\" src=\"https:\/\/am-material.com\/wp-content\/uploads\/2025\/10\/6-Ti-6Al-4V.png\" alt=\"\" class=\"wp-image-9995\" title=\"\" srcset=\"https:\/\/am-material.com\/wp-content\/uploads\/2025\/10\/6-Ti-6Al-4V.png 496w, https:\/\/am-material.com\/wp-content\/uploads\/2025\/10\/6-Ti-6Al-4V-234x300.png 234w, https:\/\/am-material.com\/wp-content\/uploads\/2025\/10\/6-Ti-6Al-4V-9x12.png 9w\" sizes=\"(max-width: 496px) 100vw, 496px\" \/><figcaption><\/figcaption><\/figure>\n\n\n\n<p><strong>Conclusion:<\/strong><\/p>\n\n\n\n<p>In summary, both of powder properties and scan pitch have a significant impact of on surface defects of printed parts.<\/p>","protected":false},"excerpt":{"rendered":"<p>Ti-6Al-4V (also known as Grade 5) is&nbsp;a common titanium alloy containing 6% aluminum and 4% vanadium, valued for its high strength-to-weight ratio, good corrosion resistance, and biocompatibility.&nbsp;It is widely used in aerospace, medical, and marine industries for applications like aircraft components, engine parts, and surgical implants.&nbsp;This alloy is known as the &#8220;workhorse&#8221;
