Its excellent material properties, versatility, and broad use in precision manufacturing make 3D printing steel an excellent option for creating high quality parts. Most types of steel can be printed, but the two types most commonly used are stainless steels and tool steels \u2014 metals that are more expensive and difficult to fabricate conventionally.<\/p>\n<h3 style=\"text-align: justify;\"><strong>Positive attributes:<\/strong><\/h3>\n<ul style=\"text-align: justify;\">\n<li>excellent strength and stiffness<\/li>\n<li>wide variety of material properties<\/li>\n<li>heat treatable.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong>Stainless steels<\/strong>\u00a0are strong, stiff steels that possess excellent corrosion resistance due to their significant chromium content (at least 12%, often up to 18%).

Often difficult and expensive to machine, 3D printing enables companies to produce high-performing parts more affordably than subtractive methods. Superalloys thrive in adverse environments \u2014 places with high heat, corrosive chemicals, or both. Though there are many printable superalloys, the two most common groups are Inconel and Cobalt Chrome.<\/p>\n<h3><strong>Positive attributes:<\/strong><\/h3>\n<ul>\n<li>Excellent mechanical properties<\/li>\n<li>Heat resistant<\/li>\n<li>Good surface stability<\/li>\n<li>Corrosion resistant<\/li>\n<li>Biocompatible (Cobalt Chrome only)<\/li>\n<\/ul>\n<p><strong>Inconel<\/strong><\/p>\n<p>The most common proprietary nickel alloy group is\u00a0Inconel.

Metal 3D printing allows engineers to create geometrically optimized copper parts like heat sinks, welding arms, and bus bars for a far lower cost. There are only a few systems capable of printing any version of copper today.

Its scarcity in 3D printing metal parts is due to two factors: low printability and relatively low costs in conventional fabrication. As a result, the potential ROI for 3D printed metal parts using aluminum, or the metal 3D printer price, is not always in favor of printing. Most common Aluminum alloys \u2013 like 6061 and 7075 \u2013 are not printed. Instead, Powder Bed Fusion machines that print aluminum typically print softer, casting grade aluminums. These casting grade alloys contain up to 12% silicon by weight and have inferior mechanical properties.<\/p>\n<h3><strong>Positive attributes:<\/strong><\/h3>\n<ul>\n<li>Low weight<\/li>\n<li>Durable<\/li>\n<li>Ductile<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"flex-auto w-full relative bg-white\" data-theme=\"light\" data-loopindex=\"11\">\n<div class=\"hc-lockup-page-content\">\n<div class=\"py-10\" data-loopindex=\"11\">\n<h3 style=\"text-align: justify;\"><strong>Alternatives to Aluminum in 3D Printing<\/strong><\/h3>\n<div class=\"richtext fontsize-14\/18 leading-20 t:leading-30\">\n<p style=\"text-align: justify;\">Because the value of printing is relatively low, it\u2019s not clear when it will become commonplace in 3D printing.
