Its main advantages are its \u003cstrong\u003eESD-safe properties and very low outgassing.\u003c\/strong\u003e Plus, its affordable price and ease of printing on common desktop printers make it something unique in this industry. Due to its excellent ESD properties and compatibility with desktop 3D printers, it’s suitable not only for parts exposed to outer space but also for advanced personal projects, such as housings for electronic devices and more.\u003c\/p\u003e\n\u003ch3 class=\"Heading-sc-bb4ac814-0 ddMMbC\"\u003eHigh-end material accessible to everyone\u003c\/h3\u003e\n\u003cp\u003ePrusas goal was to create a professional, yet affordable material that would make prototyping and manufacturing space components easier. Until now, only costly materials like PEEK, PEKK and PEI with ESD-safe properties were suitable in this field. All of these materials require highly expensive industrial printers. Prusament PC Space Grade Black can be printed on most Prusa 3D printers, which significantly reduces the final price of manufactured components and greatly increases accessibility for everyone.\u003c\/p\u003e\n\u003ch3 class=\"HTMLContent__ProductImageWrapper-sc-b437c46e-2 gAthnd\"\u003e\n\u003cimg loading=\"eager\" sizes=\"(max-width: 991px) 100vw, 750px\" alt=\"\" class=\"Image__StyledImg-sc-87ed1588-0 ZVSdp HTMLContent__ProductImagePlaceholder-sc-b437c46e-3 IHefL\" srcset=\"\/cdn-cgi\/image\/width=320,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/tiskarna%20spacegrad.jpg 320w, \/cdn-cgi\/image\/width=600,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/tiskarna%20spacegrad.jpg 600w, \/cdn-cgi\/image\/width=750,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/tiskarna%20spacegrad.jpg 750w, \/cdn-cgi\/image\/width=1000,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/tiskarna%20spacegrad.jpg 1000w,\" src=\"https:\/\/www.prusa3d.com\/cdn-cgi\/image\/format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/tiskarna%20spacegrad.jpg\"\u003eElectrostatic dissipation properties (ESD)\u003c\/h3\u003e\n\u003cp\u003eOne of the main characteristics necessary for use in space components is electrostatic dissipation. This quality is important not only for space engineers but also for anyone who works with electronic devices. In hobby use, the ESD-safe materials can be used for making custom PC cases and similar products.\u003cbr\u003e\u003cbr\u003eThe measured resistance of dissipative materials ranges between 10\u003csup\u003e4\u003c\/sup\u003e and 10\u003csup\u003e11\u003c\/sup\u003e Ohms. Ohms. Anything with higher resistance is considered insulating and anything with lower values is considered a conductive material.\u003cbr\u003e\u003cbr\u003ePrusa measured both the volume and surface resistivity of 3D printed samples from Prusament PC Space Grade Black, and the results confirmed the highly dissipative nature of the material. The volume resistivity was measured at 2.2×10 \u003csup\u003e4\u003c\/sup\u003e Ω⋅m, while the surface resistivity was 6×10\u003csup\u003e7\u003c\/sup\u003e Ω\/sq. These exceptional values were obtained directly from the 3D printed samples, without any post-processing, such as annealing or sanding, which is a testament to the filament's inherent and consistent ESD performance. This demonstrates that parts can be printed and immediately put into use for a wide range of applications requiring reliable electrostatic dissipation.\u003c\/p\u003e\n\u003cdiv class=\"HTMLContent__ProductImageWrapper-sc-b437c46e-2 gAthnd\"\u003e\n\u003cimg loading=\"eager\" sizes=\"(max-width: 991px) 100vw, 750px\" alt=\"\" class=\"Image__StyledImg-sc-87ed1588-0 ZVSdp HTMLContent__ProductImagePlaceholder-sc-b437c46e-3 IHefL\" srcset=\"\/cdn-cgi\/image\/width=320,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 320w, \/cdn-cgi\/image\/width=600,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 600w, \/cdn-cgi\/image\/width=750,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 750w, \/cdn-cgi\/image\/width=1000,format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 1000w,\" src=\"https:\/\/www.prusa3d.com\/cdn-cgi\/image\/format=auto,quality=30,blur=50\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg\"\u003e\u003cimg loading=\"lazy\" sizes=\"(max-width: 991px) 100vw, 750px\" alt=\"\" class=\"Image__StyledImg-sc-87ed1588-0 ZVSdp HTMLContent__ProductImage-sc-b437c46e-4 jtqUNX\" srcset=\"\/cdn-cgi\/image\/width=320,format=auto,quality=85\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 320w, \/cdn-cgi\/image\/width=600,format=auto,quality=85\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 600w, \/cdn-cgi\/image\/width=750,format=auto,quality=85\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 750w, \/cdn-cgi\/image\/width=1000,format=auto,quality=85\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg 1000w,\" src=\"https:\/\/www.prusa3d.com\/cdn-cgi\/image\/format=auto,quality=85\/content\/wysiwyg\/fotky\/Prusament\/pc-sg\/01.jpg\"\u003e\n\u003c\/div\u003e\n\u003ch3 class=\"Heading-sc-bb4ac814-0 ddMMbC\"\u003eOutgassing\u003c\/h3\u003e\n\u003cp\u003eVarious residual monomers or products of polymer degradation are released from the polymers under vacuum. This can affect, or even damage, the electronics used on the satellite (or any other precise machinery). Released gases can contaminate optical devices or cause inaccurate measurements of precise sensors. Finally, the gas release itself can decrease the material’s physical and mechanical properties. Manufacturing thermoplastic polymers with low outgassing levels is a great challenge, and it is usually achieved in expensive industrial-grade materials, such as PEKK and PEEK. We were able to fulfil strict requirements defined by the European Space Agency using PC (polycarbonate), which is a relatively cheap, common, and easy-to-print material.\u003c\/p\u003e\n\u003ch4 class=\"Heading-sc-bb4ac814-0 eAFRSv\"\u003eMeasured outgassing values:\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eTML (Total Mass Loss):\u003c\/strong\u003e The mass loss is represented as a percentage.
