Building upon previous projects using <a href=\"https:\/\/www.3dnatives.com\/en\/top-examples-3d-printed-rockets-290820245\/\">additive manufacturing for rocket engines<\/a>, we have yet another case study: Italian company AVIO SpA has successfully completed tests of its MPGE (multi-purpose green engine). SLM 3D printing was used in its creation.<\/p>\n<p style=\"text-align: justify;\">The project was made as part of the Italian&#8217;s government PNRR program, which is part of a movement to strength the growth potential of the country. More specifically, it falls under the purview of the &#8220;Satellite Technologies and Space Economy&#8221; theme as part of a sub-investment into in-orbit economy as Italy seeks to increase its role in the Space Race. In particular, it seems that the MPGE is part of efforts to increase Italy&#8217;s capacities in the field of space logistics for the surveillance of the space environment (Space Situational Awareness) and the management of space traffic (Space Traffic Management).<\/p>\n<div id=\"attachment_64478\" style=\"width: 710px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-64478\" class=\"size-full wp-image-64478\" src=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/mpge_conception.jpg\" alt=\"\" width=\"700\" height=\"400\" srcset=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/mpge_conception.jpg 700w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/mpge_conception-600x343.jpg 600w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/mpge_conception-160x91.jpg 160w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><p id=\"caption-attachment-64478\" class=\"wp-caption-text\">A conceptual image of the MPGE rocket engine (photo credits: AVIO SpA)<\/p><\/div>\n<p style=\"text-align: justify;\">AVIO was entrusted the MPGE project, part of an Italian Space Agency contract, and worked on it in collaboration with S\u00f2phia High Tech.

But how was it made?<\/p><div class=\"dnati-inside-article-leaderboard\" style=\"text-align: center;\" id=\"dnati-2410095160\"><a data-no-instant=\"1\" href=\"https:\/\/app.swapcard.com\/login\/event\/additiv-defense-2026\/ticket\/VGlja2V0VHlwZV83MDM4MQ==\/page\/UmVnaXN0cmF0aW9uRm9ybV81NjE4Ng==\" rel=\"noopener\" class=\"a2t-link\" target=\"_blank\" aria-label=\"LB (4)\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/03\/LB-4.gif\" alt=\"\"  width=\"850\" height=\"150\"   \/><\/a><\/div>\n<h2 style=\"text-align: justify;\">Using 3D Printing and Traditional Manufacturing to Make the MPGE<\/h2>\n<p style=\"text-align: justify;\">As mentioned, the successful test of the MPGE engine is a huge move forward for the Italian space industry. And it is particularly interesting to use because the goal of the MPGE engine is to be &#8216;greener&#8217; than many rocket engines. How? By using both hydrogen peroxide and kerosene as fuel. And additive manufacturing had quite the role to play.<\/p>\n<p style=\"text-align: justify;\">According to information from S\u00f2phia High Tech, which was charged with creating the combustion chamber, thermal control system, nozzle extension and injection section, both 3D printing and CNC machining were used to make the MPGE. More specifically, S\u00f2phia High Tech notes that its team using Selective Laser Melting, which has been qualified and is able to comply with the advanced standards prescribed by the ECSS-Q-ST-70-80C standards of the ESA, and a nickel-based material. Although the 3D printed used is not explicitly mentioned, the Aerospace company often uses a TruPrint 3000 from Trumpf and it is likely that that was what was used in this case as well.<\/p>\n<p style=\"text-align: justify;\">In addition to additive manufacturing, each mechanical part required several phases of dimensional control and validation at different stages. For example, <a href=\"https:\/\/www.3dnatives.com\/en\/heat-treatment-in-3d-printing-all-you-need-to-know-261220234\/\">heat treatment<\/a>, <a href=\"https:\/\/www.3dnatives.com\/en\/cleaning-3d-printing-post-processing-130220236\/\">depowdering<\/a> and mechanical finishing using CMC machining were all necessary steps. S\u00f2phia Tech created its own production cycles to ensure full compliance with tight mechanical tolerance, both geometric and dimensional, in the parts.<\/p>\n<p style=\"text-align: justify;\">In any case, the successful testing of the MPGE project clearly shows the advantages of combining additive and traditional manufacturing to create rocket parts. It also shows the strength of Italy&#8217;s manufacturing sector, as the entire environmentally friendly engine was made in the country. Ultimately, the MPGE project seeks to qualify an innovation propulsion system for use in both launch systems and orbital and suborbital space applications.<\/p>\n<div id=\"attachment_64477\" style=\"width: 710px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-64477\" class=\"wp-image-64477 size-full\" src=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/EN-MPGE-14052025.jpg\" alt=\"MPGE\" width=\"700\" height=\"400\" srcset=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/EN-MPGE-14052025.jpg 700w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/EN-MPGE-14052025-600x343.jpg 600w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2025\/05\/EN-MPGE-14052025-160x91.jpg 160w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><p id=\"caption-attachment-64477\" class=\"wp-caption-text\">Image Credits: 3Dnatives<\/p><\/div>\n<p style=\"text-align: justify;\">What do you think of the MPGE? <span data-contrast=\"auto\">Let us know in a comment below or on our <\/span><a href=\"https:\/\/www.linkedin.com\/company\/4987104\/\"><span data-contrast=\"none\">LinkedIn<\/span><\/a><span data-contrast=\"auto\">, <\/span><a href=\"https:\/\/www.facebook.com\/3Dnatives\/\"><span data-contrast=\"none\">Facebook<\/span><\/a><span data-contrast=\"auto\">, and <\/span><a href=\"https:\/\/twitter.com\/3Dnatives_en\/\"><span data-contrast=\"none\">Twitter<\/span><\/a><span data-contrast=\"auto\"> pages!
