A broken tool or a missing part outside Earth\u2019s atmosphere is a really big deal. Sending replacements is a long and <a href=\"https:\/\/www.c4isrnet.com\/thought-leadership\/2018\/07\/30\/the-calculus-of-cheaper-military-comms-satellites\/\">expensive process<\/a>, not to mention a risky one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the \u201cStar Trek\u201d science fiction franchise, a machine on the Starship Enterprise known as the \u201creplicator\u201d offered astronauts a simple solution: create objects on-board, on-demand and out of thin air. Today, recent <a href=\"https:\/\/www.c4isrnet.com\/industry\/2018\/10\/15\/how-the-office-of-naval-research-hopes-to-revolutionize-manufacturing\/\">advances in 3D printing<\/a>, or additive manufacturing, may be bringing the replicator closer to a reality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is just one problem: Before embracing 3D printing for space, scientists want to be sure that 3D-printed materials can function and survive in the harsh space environment over the long haul.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Harris Corporation, along with the International Space Station, is running an experiment to determine just that. The company <a href=\"https:\/\/www.harris.com\/impact\/2018\/11\/harris-to-test-3-d-printed-rf-systems-in-space\">announced<\/a> plans Nov. 29 to send a 3D-printed radio frequency (RF) antenna into space to study how such a drastic change in environments will affect its performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe objective is to fly an experiment consisting of 3D-printed materials and analyze the RF properties of those materials in a space environment,\u201d said Dr. Arthur Paolella, senior scientist for Harris Space and Intelligence Systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond the convenience of in-space conception, scientists see 3D printing as a promising method for manufacturing RF systems because of its low cost and ability to print complex shapes and conformable systems that traditional manufacturing cannot.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"443\" src=\"\/wp-content\/uploads\/2026\/08\/3d-printed-rf.jpg.jpg\" alt=\"\" class=\"wp-image-76049\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/3d-printed-rf.jpg.jpg 640w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/3d-printed-rf.jpg.jpg?resize=300,208 300w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><figcaption class=\"wp-element-caption\">Harris Corp&#8217;s innovative 3D printed radio frequency (RF) circuit and antenna, which has demonstrated performance comparable to that of circuits developed using conventional manufacturing techniques.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">\u201c3D printing provides the freedom to print complex structures more easily,\u201d Dr. Paolella said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAs far as we know, this will be the first systematic approach to analyzing 3D-printed materials for RF systems in space.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project is part of the Materials International Space Station Experiment, a series of experiments mounted on the outside of the International Space Station with the goal of investigating the effects of long-term exposure of materials to the harsh space environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are several key environmental challenges that space operations will present to the 3D-printed materials.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One immediate concern is the extreme temperature variations seen in low-Earth orbit. Because spacecrafts move in and out of sunlight many times per day while orbiting around Earth, temperatures can range from -120 degrees Celsius to +120 degrees Celsius.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, the RF systems will have to withstand high levels of ultraviolet radiation; highly reactive levels atomic oxygen; and constant impacts from micrometeoroid and other orbital debris.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The plan is to test the RF system at three points in the program: pre-flight, in-flight and post-flight,\u201d says Paolella.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe are very optimistic. The circuits developed to this date show good RF performance and have suitability for space applications.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Harris has partnered on the project with the Israeli-based company Nano Dimension, known for its innovative 3D printers. Using Nano Dimension\u2019s DragonFly 2020 printer, the companies have developed a 3D-printed proof-of-concept RF antenna designed to operate at 5.2 GHz and an RF amplifier with operation up to 6 GHz. The development of the hardware is expected to take one year, according to Paolella.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Funding for the project came from the Harris Innovation Office and the Space Florida Foundation, the aerospace economic development agency of the State of Florida.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An experiment on the International Space Station will
