[@max2562]

I love the idea. I've been watching 3D printing grow to serious industry for a while now, but haven't seen something this ambitious. However, there is something that may need to be considered and that is the standardized testing that is typically performed on equipment like this before it is considered flight/space worthy. Currently, Non-destructive testing (NDT) is performed using many techniques, all of which are designed to look for discontinuities on material surfaces or porosities in welds, etc. When things are 3D printed they are not formed or created in the same manner and so they may or may not have the same types of flaws that are found by modern methods searching for these flaws. I mean to say, it is hard to tell what types of imperfections or flaws we might see as the norm within 3D printing. It could be that the material is better in every way. There just needs to be more testing and research in these larger scale things that 3D printers can create.

[@stevegarcia3731]

I hear you loud and clear. The imperfections within the material are something that has to prove itself. Years ago I did design work for ASME Code VIII pressure vessels. We tested Japanese flanged and dished heads for the radius ends of the vessels. The Japanese steel of the day had a problem with voids that arose when forming those heads. Big failure. But testing had to be done. 2 years later Japanese steel was higher quality than from U.S. Steel Corp. But the welding process used here is so controlled, my guess is that testing will give great results. Small welds have very much less wattage than heavier welds. I also see this as eliminating 'stress risers', which are serious failure points if they exist. All metal products start out as molten. That used to be in like Bessemer furnaces. Melting it as it is built is so effing cool. Removing all the machining and forming steps is a quantum leap in manufacturing slash assembly. Removing the individual parts and cutting down on how many - that is absolute genius, whatever company does it. I am retired now, but if I were 25 or 35, this is a company I would want to work with. The amount of creativity they get to do would have suited me perfectly. limi

3d printing plastic is is now affordable to any one, the Positron v3 is like $90 more precise that almost any non resin 3d printer and it can FOLD the thing can fold into a shape smaller than a laptop adding on to that is is among the fastest plastic 3d printers ever.

[@erikgrahn3363]

Spray it with spot checker and x ray it

[@dethtour]

I do inspections for the refineries. CWI and various API's stuff like this won't get x-rays. They'll end up doing UT (Ultrasound testing) due to how big it is. With a UT they can see any imperfections in the metal without using dinosaur sized film for X-ray. I'm pretty sure they check PT (Penatration testing) and before doing the UT. Interesting how simple this process is. I'm pretty sure porosity can be mitigated in a room filled with argon gas to keep the filler clean.

[@max2562]

@@dethtour I can't imagine the PT process for something this huge, but UT has come so far that it would likely be very easy. The problem I'm seeing now is that they talked about wanting to have this technology on Mars to make equipment there. I know they want to create buildings and structures, which arguably would not need much NDT, but if they are planning on creating anything space worthy while on Mars then there may be issues with that. The only way is if they created facilities large enough like hangars to house the equipment and have atmosphere. UT might be best without atmosphere, but I haven't really ever thought about that before. Regardless, there still is atmosphere on Mars just not much of it. Gotta wonder tho, if the low oxygen and no water environment will be a large enough advantage to the equipment's prolonged use.

This is standard stuff in metal 3d printing - just here a lot of it is done with an actual welder. The 3D printed parts are also made larger so they can be heat treated and end up with dimensions that frequently are finish machined to proper size.

[@madhouse5213]

You can also check out resonance filtering in Klipper 3D printer software. It uses resonant frequency models of printhead at high accelerations to cancel ringing, thus enabling faster printing. Oh, and it's free software (free as in speech ;) )

[@JoshGariepy]

As a welding student - im curious how they avoid problems with oxide layer inconsistencies seeing as its aluminum welding. I guess maybe the printer runs cleaning passes before depositing metal?

[@vitruvianman7170]

As a pressure vessel inspector, I have serious doubts that that tank can handle 50psi of pressure. All it would take is one microscopic flaw in one of the welds would cause catastrophic failure. Welded metal air cooled as it is in this video is way weaker than forged or rolled metal. I would like to see the pressure testresults.

[@Jerichoswa11]

@@JoshGariepy I'm pretty sure the wave form changes are wiping any oxidation.

[@JoshGariepy]

@@Jerichoswa11 thats true, but i think it has potential for inclusions regardless unless the printer has some sort of precleaning action prior to adding filler

[@vitruvianman7170]

@@JoshGariepy agree, if they did the welding in a controlled chamber filled with a gas maybe. This is just a room at ambient temperature. Molten metal that cools at room temperature inherently cracks, when welding, preheating is used and post heating to align the grains in the welds. My bet there is cracks all through these welds.

At a minimum, a company that can rapidly prototype large, complex, and precision parts is never going to run short of potential clients. As Scott said once you get to the point of mass producing parts the benefits of 3D printing get eaten away by dedicated tooling. But if they focus on the flexibility of 3D printing, they can pivot to fill a niche in basically any manufacturing industry.

[@thornelderfin]

Well said! Plus even if you have dedicated factories for mass production you will still need the 3D printing for prototyping improvements.

They can pratically be the company that would handle almost all the prototyping of rockets in the industry.

even if it is 10%, youd need 10 launches to lose a full other launch on cost, so it is not much, besides its a prototype, sanding it is not the way to go as you could oversand it and make it too weak, i think they seek to improve the 3d printing method to make it less rough, tackle the main thing, not the consequence, also if the whole rocket warps just a hair thickness distance from tip to bottom, thats already a win.

If we assume this rocket will be successful, the most amazing part of this project is not the scale of the printers, nor the "vision" of the start up CEO. It is the metallurgy engineers who figured out how to comply with all the loads and structural criteria while depositing material horizontally. As mentioned on the video, it is often said that 3D printed objects are weak on shear, but this man is telling us they figured a way to make it stronger through temperature control (I am impressed if that is true). Interesting that there were no "longerons" running at the length of the rocket, just the internal circular frames, do they carry bending loads on the skin or will they add something to stabilize later?

[@bestcreations4703]

Its more than likley due to the use of metal and the over extrusion, metal has a cool characteristic of being very good at transferring energy heat and electricity so when you heat some parts up the other sections around it get very hot very quick and improve adhesion not to mention metal works differently on a more fundamental level think like cold welding where two parts can just spontaneously fuse which i would imagine helps here.

Whether using cintering and dust or these extrusion based printers, it's next to impossible to control the crystal structure which usually results in far more internal impurities and voids (can't remember the technical term it's been a few years since I researched this topic). This creates very brittle and non-heat resistant parts. Its why 3D printing has yet to be widely applied in so many industrial application; there currently does not exist a cost effective method of ensuring microstructural stability in the metal relative to traditional casting and manufacturing methods. Now if theyve actually figured something new out that's huge, but this is a very "I'll believe it when it makes it to space" situation as someone he's been around this manufacturing method.

I think the key thing they’ve got here is that ability to iterate so rapidly. That could be a really exciting niche for them to fill - someone needs a better nozzle or a better tube or a better second stage, cryogenics, whatever - these guys get a contract to run through a whole bunch of algorithmically generated iterations on that item, then sell the designs to the larger companies so they can produce them at scale. Like Scott said, in the long run it becomes cheaper when you standardize manufacturing, but in the short term, developing incrementally better pieces for other companies with standardized manufacturing could really speed up this kind of Space Race 2.0 we’ve got going on right now.

For that company being viable. They can do rapid prototyping of gigantic complex parts, not just for rockets. The advantage of 3D Printers is that they can print any shape, so they aren't limited to printing rockets. They could branch out to printing just about any kind of low volume metal structure that would take far longer to fabricate. I also see a lot of promise in their tech for creating scientific experiments and instruments. These are often very costly and often only serve a very limited purpose while having rather high complexity which causes design iteration to be a nightmare.

The reality, despite how you want to twist the percentages around, is that rocket weight takes up weight that could be used for payload.

Isn’t it just an awesome boom to world’s engineering to suddenly drop tools and see 3D printing take the short cut to making incredibly complicated items as one piece and with design improvements within months. This is where humanity gets to reach betterment for all and at a gallop. A very exciting time😳

It's great and not so great. Great for reducing manufacturing costs in the long-run and quickly building upon past iterations, not so great if you as a consumer want to fix something or start adding mods, kinda sounds like you're SOL. Especially when he mentioned there are certain forms which are only possible when 3d printed, that immediately makes me worried that it's nigh impossible to fix them if there's ever an issue. You use lose that modularity when you build everything in one go (technically layers but whatever). Having said that, the time and money savings for projects like these are still way worth it. I would be very curious to hear his opinion about rocket reusability if a certain section breaks; how do you approach repairing it, if possible in the first place?

[@theg4mer6474]

@@yerpderp6800 No need to repair or mod if you can just toss it into the recycler and print off a new one.

[@z-beeblebrox]

@@yerpderp6800 The trade-off though, is that any person with access to a 3D printer and the necessary material only needs access to a 3D model of the part and it's theirs. It doesn't even need to be an official model, as long as the measurements are accurate any hobbyist could design one and put it on a schematics exchange.

I bought my daughters an ender 3 two years ago. They are 9yrs and 13yrs old now with 4 printers. The oldest wants to be an aerospace engineer and the youngest (4th grade) is designing .stl files on fusion 360 . 3d printing is the future

"it just adds 5-10% extra weight" Isn't that quite a massive weight increase when we talk about rockets?

[@benporter1997]

Lol my thoughts exactly.

[@labrinth999]

That and "It doesn't add any air friction" didn't sit right with me...

[@bestcreations4703]

I was thinking the same thing however i would also say keep in mind they are more than likley referring to the weight of just the casing compared to a proper casing and a difference in 5% of that is very small when compared to the weight of the fuel which it holds but i do agree it is still a concern maybe the reduction in weight isnt worth the additional manufacturing required to go in and smooth out all of the surfaces

[@KelsomaticPDX]

I had the same thought. My guess is that maybe there are weight savings in other parts of the rocket that make up for this difference or that there is post-print finishing done to reduce weight. Just guesses.
