3D Printing Technology in the Aeronautics, Space, and Defense Industry

By : admin

Today, let us know about 3D printing technology in the aeronautics, space, and defense industry.


Additive manufacturing has many characteristics that are useful in the aerospace industry. 3D printing technology has been able to create complex shapes that are necessary for integrated functions, with reduced waste materials. And although the production is in small batches it can produce customized parts at a low cost. Other than that, this technology is able to reduce maintenance time because of its capability to manufacture parts on demand. The printed products are available at high strength & stiffness at lightweight.


With those laid out, here we will discuss the application of 3D printing in the aeronautics, space, and defense industry.


Aerospace Parts and Rockets

Both metals and nonmetals aerospace parts can be manufactured by 3D printers, such as aero-engine components, turbine blades, and heat exchangers.  Non-metallic methods of 3D printing have been used for the rapid prototyping of parts to create fixtures, and interiors made of plastics, ceramics, and composite materials.


To aid the astronauts to go to their exploration missions, rockets are needed. Conventionally made rockets are sure to have been around since the beginning of space missions. But companies have developed a 3D printed rocket for all primary components of their engine. This method of manufacturing is able to reduce the average launch costs by 95%.


Zero Gravity 3D Printer

The first space 3D printer was developed. It was made to withstand zero gravity and the forces of a rocket launch before even printing anything. A similar printer is commercially available and ready to be used on Earth. With twice a size, they can print out larger and more complex objects faster, with better precision, using multiple aerospace-grade materials all at once. 


A company has rented a commercial version of this 3D printer to be used on the ISS by NASA under a joint partnership. The astronauts are highly benefited by the addition of these printers in space. They allow astronauts to manufacture anything they need on-demand in their missions. Keeping a supply chain from Earth to the ISS is costly and slow.


Large Scale 3D Printing in Space

Here, we are talking about a space-scaled 3D printer that orbits around the Earth or Moon. Like 80 feet in diameter and 300 feet long that spins around its long axis. And they are meant to print out large objects. 


For these printers to work you will need sunlight, sand, and artificial gravity to hold things down. These printers work by melting sands layer-by-layer by concentrated sunlight and turn them into 3-dimensional solids. Unfortunately, space doesn’t really have a lot of sands. So, these printers use lunar regolith from the moon, or by grounding up asteroids already in orbit.


The space 3D printers have their own use. Obviously, they are meant to be used in space. Specifically, these printers are needed to produce parts of inhabitants in orbit. Unfortunately, these printers are still in a form of an idea by Glen Hendrix, not yet a reality. The execution of this idea might not 100% reflect what is portrayed here.


3D Printing in the Military

The United States Army has invested time and resources into 3D printing technology. One of the results is the creation of 3D-printed grenade launchers. It even has a nickname, RAMBO. The grenades for RAMBO’s are also 3D printed. It consists of 50 individual parts and 48 of them are made by 3D printing.

  1. Hey there! I could have sworn I’ve been to this blog before but after reading through some of the post I realized it’s new to me. Anyhow, I’m definitely glad I found it and I’ll be book-marking and checking back frequently!

  2. I used to be recommended this website by my cousin. I’m not positive whether or not this post is written by way of him as no one else understand such unique approximately my trouble. You are incredible! Thank you!

  3. I will immediately snatch your rss feed as I can not to find your e-mail subscription link or newsletter service. Do you’ve any? Please allow me recognize in order that I could subscribe. Thanks.

  4. You actually make it seem so easy with your presentation but I find this topic to be actually something that I think I would never understand. It seems too complex and very broad for me. I’m looking forward for your next post, I抣l try to get the hang of it!

  5. It is perfect time to make a few plans for the future and it’s time to be happy. I’ve learn this publish and if I may just I desire to suggest you few attention-grabbing things or suggestions. Perhaps you can write next articles relating to this article. I desire to read more things approximately it!

  6. Good day! I know this is somewhat off topic but I was wondering if you knew where I could get a captcha plugin for my comment form? I’m using the same blog platform as yours and I’m having difficulty finding one? Thanks a lot!

  7. After examine a few of the weblog posts on your website now, and I truly like your way of blogging. I bookmarked it to my bookmark web site checklist and will probably be checking back soon. Pls take a look at my website as properly and let me know what you think.

  8. It is in point of fact a nice and useful piece of information. I抦 happy that you shared this helpful information with us. Please stay us up to date like this. Thank you for sharing.

  9. Thanks for your article on this website. From my own experience, there are times when softening way up a photograph may provide the digital photographer with a little an inventive flare. Often times however, the soft cloud isn’t just what exactly you had planned and can frequently spoil a normally good photo, especially if you thinking about enlarging that.

  10. Oh my goodness! a tremendous article dude. Thanks Nevertheless I am experiencing issue with ur rss . Don抰 know why Unable to subscribe to it. Is there anyone getting equivalent rss downside? Anyone who is aware of kindly respond. Thnkx

  11. Hi, i believe that i saw you visited my website thus i return the desire?I am attempting to in finding things to enhance my site!I assume its adequate to make use of some of your ideas!!

  12. I have really learned new things as a result of your blog site. One other thing I would really like to say is the fact newer computer operating systems are inclined to allow far more memory to use, but they also demand more memory simply to perform. If a person’s computer cannot handle far more memory and also the newest computer software requires that memory increase, it is usually the time to shop for a new Laptop or computer. Thanks

  13. Hmm it appears like your site ate my first comment (it was extremely long) so I guess I’ll just sum it up what I had written and say, I’m thoroughly enjoying your blog. I too am an aspiring blog writer but I’m still new to everything. Do you have any points for first-time blog writers? I’d certainly appreciate it.

  14. Hi there! I could have sworn I’ve been to this website before but after checking through some of the post I realized it’s new to me. Nonetheless, I’m definitely happy I found it and I’ll be bookmarking and checking back often!

  15. Wonderful goods from you, man. I have understand your stuff previous to and you’re just too great. I actually like what you’ve acquired here, really like what you are saying and the way in which you say it. You make it enjoyable and you still take care of to keep it sensible.
