Considering the appealing combination of thermoplastics and rubber for a variety of necessary applications, it\u2019s easy to understand why TPU is so popular in 3D printing as well as other traditional types of manufacturing like<a href=\"https:\/\/www.shapeways.com\/business\/injection-molding\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\"> injection molding<\/a>. The versatility of TPU stems from the combination of hard and soft segments making up its block polymers, lending itself to the most common reasons manufacturers turn to 3D printing today: versatility and customization.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The Advantages\u2014Where to Begin?<\/strong><\/h3>\n\n\n\n<p>Shapeways offers TPU in off-white for use with Selective Laser Sintering (SLS), using EOS 3D printers, as well as<a href=\"https:\/\/www.shapeways.com\/blog\/archives\/40811-industrial-3d-printing-for-high-performance-parts.html\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\"> Ultrasint TPU01<\/a> material from BASF, available in gray, using Multi Jet Fusion 3D printers. These materials offer multiple benefits over other elastomers, to include:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Superior tensile strength<\/strong> \u2013 Defined by how much strain a part can take before fracturing, tensile strength is measured through units of pressure called megapascals (MPa). With a high tensile strength of up to 60 MPa, coupled with good flexibility, TPU can be used for high-performance parts that must stand up to rigorous use.<\/li><li>&nbsp;<strong>Elongation at break<\/strong> \u2013 This material characteristic is tested by comparing where a part breaks after being strained, versus its original length. TPU is known for high elongation at break due to its elasticity, making it especially useful in critical applications because it is also so tough.<\/li><li><strong>Excellent load-bearing capacity<\/strong> \u2013 This is an important measurement as it testifies to how much weight a 3D printing material can handle\u2014a factor that could be extremely important in applications requiring high-performance products that are expected to last, including mechanical devices like tubing, hoses, and seals.<\/li><li><strong>Resistance<\/strong> \u2013 TPU is able to stand up to many different factors because of its natural resistance, which is why it is considered such a multi-purpose 3D printing material. This includes resistance to chemicals, oil and grease, harsh weather, heat, and abrasion.<\/li><\/ul>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2021\/07\/Ultrasint-TPU01.png\" alt=\"Ultrasint TPU01\" class=\"wp-image-41781\" width=\"500\"\/><\/figure><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Typical Applications for Thermoplastic Polyurethane<\/strong><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Automotive<\/strong><\/h4>\n\n\n\n<p>While the <a href=\"https:\/\/www.shapeways.com\/blog\/archives\/40948-the-impact-of-3d-printing-in-the-automotive-industry.html\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"automotive industry (opens in a new tab)\">automotive industry<\/a> has been using 3D printing for decades in prototyping, as well as functional parts for both the interiors and exteriors of vehicles, TPU allows for the design of components that focus on greater comfort for the driver, like customized headrests and seats. With TPU, textures may range from soft and luxurious, to rigid and functional, depending on the interior part for a vehicle. There are a variety of different finishes available too for automotive applications.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Consumer accessories&nbsp;&nbsp;<\/strong><\/h4>\n\n\n\n<p>The 3D printing industry is well known for expanding options to <a href=\"https:\/\/www.shapeways.com\/industry\/consumer\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"consumers (opens in a new tab)\">consumers<\/a> in the area of accessories, mainly due to the enormous potential offered by expanded design freedom and the ability to customize. This is especially true for items like smartphone cases, allowing customers to completely personalize an item, adding exciting and unique touches to an item that is pretty much impossible to live without. TPU is also an excellent choice for adding quality and customization to highly functional items used daily like rubber mats and products like handles.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Footwear<\/strong><\/h4>\n\n\n\n<p>3D printing has made a powerful impact within the footwear industry, and on multiple levels.
