Lightweight Combustion Chamber Part of 3D Printed Rocket Engine: The Cool Parts Show #30

Masten Space Systems developed a lightweight, reusable rocket engine for NASA’s aim to fly repeated trips to the moon in rapid sequence with little delay between launches. The “Broadsword” engine was made using laser powder bed fusion by Elementum3D on a machine from EOS. Additive manufacturing (AM) enabled sophisticated internal cooling channels and the consolidation of the engine’s parts into just three major components, all 3D printed, including the combustion chamber seen in this episode.
AM also allowed for light weight through the choice of material. Rather than a high-temperature (and heavy) aerospace alloy, this chamber is made of a metal matrix composite developed by Elementum3D that combines aluminum for light weight with ceramic for high temperature performance.

Been watching every piece of metal 3D printing content I could get my hands on for years, I can't believe CZcams has only now recommended me one of your videos. The production quality, information density and all the expert interviews are insanely good. It's a crime that you have so little views and subscribers. There millions of people out there like me, who would like to watch your videos.

[@AdditiveManufacturing]

Thank you very much, that's awfully kind. If metal AM is your thing, we have articles and a podcast that expand on the subject as well: www.additivemanufacturing.media/hashtag/metal Thanks for watching!

Just when your guest was giving a shout-out to NUMECA (the computational fluid dynamics company), they changed their name to Cadence.

[@Namoona3DLabs]

Amazing to see and know this and thank you for this show

[@Lulu58e2]

10 trips in 10 days. That's exciting.

[@slevinshafel9395]

nice but i want more details on it. roughnes inside(specially in the coler chanels) and tolerance or conection betwen 3 parts. are colling chanels go in all 3 parts? leaks because conection?

[@clavo3352]

Very cool video! I heard the new Raptor engine is also a printed engine made of a unique textile but i forget the textile name. Starts with a "C" i think.

[@bigdogben]

pretty sure its mostly machined. Uses a special alloy idk what spacex calls it though

[@Goryar]

Cool very cool 😎

[@stochasticsignal1951]

This is a really cool use of 3D printed technology. Do they have to do any post processing to the engine, or can the machine achieve this level of finish right off the bed?

[@aerospacefuzz]

There was post machining performed on this part, the flange sealing surface needs to be cleaned up and the fitting ports need to be cleaned up as well. That really nice outer surface finish you see was all as printed though!

[@SeanKula]

Hey I have a few questions. How much did this cost to 3d print? I must be much cheaper than having 100s of workers working on the rocket.

[@AdditiveManufacturing]

We don’t have access to the specific cost and pricing info, but you are right about the source of the savings. Because the chamber with all its internal complexity was printed in one solid piece, additive manufacturing is a direct replacement for joining and assembly work.

[@SeanKula]

@@AdditiveManufacturing Ah I see thank you. Yeah this will open up many opportunities for small business. The future looks bright.

Turbo pump selang apinya ngambil dari api combution camber jadi semakin nekan semakin cepat semakin cepat semprotanya semakin kenceng

[@ayoksusune8095]

Sesnya jauh ya berarti tekananya besar

[@ICHIMANExTKND]

Wait..
