This article follows the history of the use of 3D printing in new space companies. Towards the end of the article, we will also look at another advanced manufacturing technique used by these companies: high-pressure die casting.<\/p>\n
Defining 3D Printing<\/strong><\/h2>\nLet\u2019s start with a reminder of what 3D printing technology involves. There is no better place to look for the definition of 3D printing than from the masters of 3D printing, Autodesk.<\/p>\n
Autodesk defines<\/a> 3D printing as \u201ca process by which physical objects are created by depositing materials in layers based on a digital model.\u201d The same source adds that \u201c3D printing technology can be used to create everything from prototypes and simple parts to highly technical final products such as airplane parts \u2026, eco-friendly buildings, life-saving medical implants and even artificial organs using layers of human cells.\u201d<\/p>\nAutodesk identifies three primary methods<\/a> employed when manufacturing items using 3D:<\/p>\nFused filament fabrication (FFF)<\/strong>: Mainly in manufacturing consumer products, this method heats and extrudes plastic material in layers that form the required product. It\u2019s also called fused deposition modeling (FDM).<\/p>\nStereolithography (SLA):<\/strong> Uses UV light to harden or cure raisings, one layer after another.<\/p>\nSelective laser sintering (SLS)<\/strong>: Fuses powdered materials using lasers, layer by layer.<\/p>\nWhy Space Manufacturers Are Turning to 3D Printing<\/strong><\/h2>\n![\"Why](\"https:\/\/moldie.net\/wp-content\/uploads\/2021\/08\/Why-Space-Manufacturers-Are-Turning-To-3D-Printing.jpg\")

The additive manufacturing software provider, AMFG, provides some insights into the impact of 3D manufacturing in the space travel field. The company notes<\/a> that the \u201cspacecraft manufacturers are faced with the challenge of accelerating rocket development and production, while also reducing costs and increasing efficiency.\u201d<\/p>\nAMFG says<\/a> that the traditional rocket manufacturing process involves several prototyping cycles and phases of production, rendering the process expensive and time-consuming. The same source says that the 3D manufacturing process can reduce the manufacturing time for parts from a traditional 14-week period to only a few weeks, giving manufacturers significant savings on time and costs.<\/p>\n3D manufacturing also ensures the precision of parts, which is a challenging task when using traditional manufacturing methods.<\/p>\n

Elon Musk established SpaceX in 2002. His mission was to reduce the cost of traveling to space so that humans could eventually colonize Mars. According<\/a> to SpaceX, this would be achieved through the use of \u201cfully reusable launch vehicles that will be the most powerful ever built, capable of carrying humans to Mars and other destinations in the solar system.\u201d<\/p>\nOn September 5, 2013, Musk announced<\/a> via a tweet that \u201cSpaceX SuperDraco inconel rocket chamber w regen cooling jacket emerges from EOS 3D metal printer.\u201d<\/p>\nThe source of news on space exploration, innovation, and astronomy, Space.com reports<\/a> that \u201cSpaceX sent its first 3D-printed part into space early this year [2014].\u201d The same source adds that \u201cThe part, a rocket engine main oxidizer valve, flew aboard SpaceX\u2019s Jan. 6 launch of a Falcon 9 rocket carrying the commercial Thaicom 6 telecommunications satellite to orbit.\u201d<\/p>\nThe practicality of using 3D printing to make rocket parts was validated by the fact that the valve worked as required under strenuous conditions, including under extremely low temperatures.<\/p>\n
SpaceX is also using 3D printing technology to produce other accessories such as helmets. According<\/a> to 3Dnatives.com, \u201cEach helmet features a visor, valves, locks, and microphones.\u201d<\/p>\nBlue Origin: Making Significant Investments in 3D Printing\u00a0 <\/strong><\/h2>\nBlue Origin is the aerospace manufacturer established by the founder of Amazon, Jeff Bezos. The company was launched in 2000 in Kent, Washington. \u201cWe\u2019re committed to building a road to space so our children can build the future,\u201d reads the company\u2019s mission statement<\/a>.<\/p>\nBlue Origin also says<\/a> that it is living up to its mission statement by developing \u201cpartially and fully reusable launch vehicles that are safe, low cost and serve the needs of all civil, commercial and defense customers.\u201d<\/p>\nAn important part of ensuring that low-cost and safe Blue Origin\u2019s space travel products become the norm is the 3D printing technology. 3DPrintingIndustry.com quotes the Blue Origin president, Rob Meyerson, who says<\/a> that his company \u201chas made a significant investment in 3D printing.\u201d He adds, \u201cWe\u2019re all in on adopting new technologies and taking full advantage of the possibilities.\u201d<\/p>\n3DPrintingIndustry.com also reports<\/a> that Meyerson illustrated, in a presentation, the time- and cost-saving benefits introduced by 3D printing compared to the traditional casting methods. In the presentation, Meyerson showcases a part that took three months to make using 3D printing. The same part takes over 12 months using traditional casting methods.<\/p>\nThe 3D Printed Engine Taking the First Woman to the Moon\u2019s Surface<\/strong><\/h3>\n![\"The](\"https:\/\/moldie.net\/wp-content\/uploads\/2021\/08\/The-3D-Printed-Engine-Taking-the-First-Woman-to-the-Moons-Surface.jpg\")
<\/p>\n
In December 2020, 3Dprint.com reported that \u201cBlue Origin has created a three-stage lander that could take the first woman and next man to the surface of the Moon by 2024.\u201d<\/p>\n
The exciting part is that the BE-7 engine powering the lunar lander system was manufactured using 3D technology. This is confirmed by Bezos, who says<\/a>, \u201cThe BE-7 is a high-performance, additively manufactured liquid hydrogen \/ liquid oxygen lunar landing engine with 10,000 lbf of thrust – deep throttling down to 2,000 lbf for a precise landing on the Moon.\u201d<\/p>\nBut that’s not all. Bezos used an Instagram video<\/a> to announce that \u201cThis is the engine that will take the first woman to the surface of the Moon.\u201d According to the Washington Post, that woman was Wally Funk, who lost her chance to go to space in 1961 because<\/a> \u201cNASA had no program for female astronauts.\u201d<\/p>\nFunk may not have landed on the surface of the Moon, but she would eventually get a chance to travel to space on July 20, 2021. She was 82 years old. Funk was one of the three passengers who traveled with Bezos in what Blue Origin dubbed<\/a> its \u201cfirst human flight.\u201d<\/p>\nLaunching a Fully 3D-Printed Rocket into Orbit <\/strong><\/h2>\nRelativity Space is a space company established in 2015. The company has indicated its goal<\/a> to be \u201cthe first space company to successfully launch a fully 3D-printed rocket into orbit.\u201d<\/p>\nBut what does \u201cfully 3D-printed rocket\u201d mean in reality. Denrie Perez, who writes for Engineering.com, has the answer<\/a>: \u201cFrom the engines to the fuselage, Relativity is automating almost the entire manufacturing process.\u201d<\/p>\nPerez adds<\/a> that 3D printing has allowed Relativity the ability to modify its designs quickly. She notes that to beat competitors like SpaceX, the company is selling customization. \u201cThe use of 3D printing would enable the company to repeatedly modify capsules to fit any kind of satellite,\u201d she writes.<\/p>\nForbes.com quotes the Relativity CEO, Tim Ellis, who says<\/a> that \u201cwith 3-D printing, we\u2019re able to make rockets faster, with a smaller, leaner factory and fewer processes.\u201d<\/p>\nOn June 8, 2021, Alex Knapp of Forbes.com reported<\/a> that Relativity had raised $650 million in a Series E venture round. He reports that the \u201ccapital is geared towards accelerating the development of the company’s Terran R rocket, which will be completely 3D-printed and capable of launching bigger payloads than Elon Musk\u2019s Falcon 9 rocket.\u201d<\/p>\nOther Space Companies Using 3D Printing<\/strong><\/h2>\nWith the benefits of 3D printing in the space field, it\u2019s not surprising that every serious space company seems to be doing something about manufacturing parts using the technology.<\/p>\n
Michael Petch, writing for 3DPrintingIndustry.com, reports that the President and CEO of Virgin Galactic, George Whitesides, had informed<\/a> him during an interview that the company\u2019s \u201cgoal is to reduce the amount of time it takes to produce our engines from many months down to eventually weeks.\u201d Petch indicated that 3D would play a profound role in meeting this goal.<\/p>\nRocket Lab is a space travel company described<\/a> by the MIT Technology Review as \u201cThe small firm that launched the 3D-printed space revolution.\u201d Peter Beck established the company in 2006.<\/p>\nThe MIT technology review reports<\/a> that \u201cSix of the [Rocket Lab] rockets have launched successfully so far\u2014each equipped with nine Rutherford engines that are created primarily using metal 3D printing, as are a number of other elements on board.\u201d<\/p>\nIs There Space for Other Methods? <\/strong><\/h2>\nEven though new space companies are forging ahead with 3D technologies, it looks like other methods that have been used for ages still have room in the industry.<\/p>\n
An example of a technology that has been used for many years but is still relevant today is plastic injection molding<\/a>.<\/p>\nProof that these methods still have a future can be seen in a recent job post from SpaceX indicating that the company is hiring engineers and technicians versed in relevant technologies.<\/p>\n
The ad states<\/a> that these engineers and technicians will \u201cwork closely with our engineering teams in the early phases of high pressure die casting process development and equipment commissioning and drive the development of aluminum die casting<\/a> at the company.\u201d<\/p>\n
