We’ve at all times analyzed the 3D printing market, specializing in what wants to vary to search out extra functions, turn into cheaper, and improve our yield. Nonetheless, take into account a thought experiment the place we reverse this angle. What if we explored methods to extend the additive manufacturing (AM) market tenfold inside two years? This might imply rising from an industry-wide complete income of $14.7 billion right now to $147 billion by 2026.
Whereas this may increasingly appear bold, the fast modifications throughout the pandemic demonstrated how rapidly issues can shift beneath extraordinary circumstances. As an illustration, Peloton’s market cap soared to $44 billion, there have been shortages of bathroom paper and trampolines, and tens of millions took up dwelling baking. The 3D printing {industry} itself obtained a major increase throughout this time. Can we determine extraordinary eventualities that might as soon as once more considerably improve our international relevance and {industry} dimension?
Kessler Syndrome
Kessler Syndrome refers back to the idea the place a self-reinforcing cycle emerges from satellite tv for pc particles as soon as it reaches a sure threshold. When one satellite tv for pc crashes into one other, it releases house particles throughout a collection of orbits. This particles, in flip, collides with extra satellites, ensuing within the launch of much more particles. A seminal 1978 paper highlights how the chance of satellite tv for pc collisions escalates because the variety of satellites in orbit will increase. As House.com places it:
¨ESA estimates that Earth orbit harbors a minimum of 36,500 particles objects which can be greater than 4 inches (10 centimeters) vast, 1 million between 0.4 inches and 4 inches (1 to 10 cm) throughout, and a staggering 330 million which can be smaller than 0.4 inches (1 cm) however larger than 0.04 inches (1 millimeter). These objects pose greater than only a hypothetical menace. From 1999 to Might 2021, for instance, the ISS performed 29 debris-avoiding maneuvers, together with three in 2020 alone, in accordance with NASA officers. And that quantity continues to develop.
In a single occasion, “China deliberately destroyed considered one of its defunct climate satellites in a much-criticized check of anti-satellite expertise that generated greater than 3,000 tracked particles objects and maybe 32,000 others too small to be detected.”
CubeSats
At one level, the Kessler Syndrome might surpass a form of level of no return with out our consciousness, doubtlessly resulting in a cascade that might terminate a major variety of satellites in a single, in depth satellite tv for pc mass extinction. At the moment, there are over 9,494 satellites in orbit, a quantity considerably greater than in earlier years, and the rely is quickly rising. The Authorities Accountability Workplace forecasts greater than 58,000 launches by 2030. The intriguing side of this state of affairs is the uncertainty relating to the purpose of no return. Nonetheless, it’s anticipated to happen finally because of the restricted variety of obtainable orbits and the even scarcer variety of fascinating ones. Whereas it may not occur by 2030, the scenario might turn into vital by 2050 if we attain 100,000 satellites. When the seminal paper on this subject was printed, fewer than 200 objects have been launched into house yearly. This quantity has since escalated dramatically: 134 satellites have been added in 2012, 456 in 2017, 1,274 in 2020, and a couple of,664 in 2023. At the moment, there are 5,504 Starlink satellites alone in orbit.

Now, ought to this not be the case, then maybe somebody will do it deliberately. The US has, by far, the perfect and most spy satellites on the earth in orbit. China has round half of this, and Russia lower than this, whereas the remainder of the world has solely a handful per nation at most. What when you have been about to be attacked by the US, and also you knew that its artificial aperture satellites might monitor you always, and its navy satellite tv for pc communications methods have been about to coordinate a large assault on you? GPS is just not solely there to make sure your pizza arrives on time however may also information bombs and different ordnance to your location.
You’re preventing for survival, so what do you do? You launch a satellite tv for pc that disables quite a few others. Cluttering the Low Earth Orbit (LEO) would make it troublesome for something to bypass this zone into additional house, making a form of demise belt of house junk. LEO can be the place many spy satellites reside. The LEO space covers 1.05 million km² as much as 580 kilometers in altitude, so that is no small feat. However, assuming China’s expertise is indicative, destroying 2,000 satellites—about half of all annual launches—would create over 30 million, and presumably a complete of 60 million, house junk objects in orbit, all posing a threat of destroying extra satellites.
The US would lose GPS capabilities, focusing on accuracy, and common climate and indicators intelligence. The complete US struggle system, which is predicated on info consciousness and availability, could be crippled with out satellites, a minimum of briefly. It must embark on a satellite tv for pc spree to regain superiority, whereas different international locations would possibly turn into concerned in their very own arms races, seeing a chance to realize a bonus over the US.
In the meantime, new satellites would must be launched which can be both larger, higher, or geared up with defenses towards house junk. Alternatively, applications may very well be developed the place cleanup satellites (or maybe an orbiting wall) would clear up the junk, permitting for secure launches. Satellites would want extra propulsion methods or batteries, and/or photo voltaic arrays to maneuver round objects, neutralize them, or stand up to impacts. And also you would possibly keep away from a US assault, a minimum of for some time, as a result of, boy, they may actually be upset about shedding entry to their Netflix.
Why and How May 3D Printing Profit from this?
One caveat for this technique could also be that if the US’s nuclear focusing on and strike functionality have been compromised via interference with each land and submarine-based ICBMs, the US would possibly, in actual fact, be pressured to make use of nuclear weapons when you additionally possess nuclear capabilities. Nonetheless, assuming that you just would not have nuclear weapons or you might be sufficiently knowledgeable about US nuclear doctrine to take the danger, then this technique would possibly simply work. Now, why would a mass die-off of satellites profit 3D printing? First off, any launch car schedule could be expedited, and any launch firm would see its order books crammed for many years as business corporations, alongside governments, wrestle to deploy new satellites.
How Many Printers Would We Want?
To speed up launch car manufacturing, new launchers and engines could be required, and the propulsion methods of practically all launch methods at the moment are manufactured utilizing AM. If we assume there are round 200 launches per 12 months to maintain up with all resupply missions and the present satellite tv for pc launch schedule, and that every launch includes 2000 satellites, let’s take into account that with a good utilization of 3D printing within the propulsion system, attaining an excellent yield, an organization would want three quad-laser methods with a construct quantity of 500 x 280 x 365 mm (e.g., SLM 500, M400) and three massive powder mattress fusion methods (multi-laser, equivalent to a customized AMCM) for one 12 months to fabricate elements for 5 launches. This demand is predicted to stay kind of fixed.
Whereas these estimates are very approximate, we are able to count on the variety of additive elements to extend as productiveness step by step improves, particularly because the world turns into extra accustomed to multi-laser methods. Concurrently, rockets and payloads, in addition to the dimensions of additive elements, will doubtless develop. Subsequently, our productiveness would possibly improve as we maximize using additive elements on rockets and enhance our yields via software program optimization of outdated machines and the introduction of quicker new machines.
Assumptions
In disaster mode, so as to add further capability, we’d generate roughly $516 million in income from the machines in a 12 months, primarily based on the pricing of three machines at $1.3 million every and three machines at $3 million every, multiplied by 40. This determine is probably half of what we at present generate. In fact, choosing costlier machines or needing extra would drastically change the calculations. This estimate doesn’t embody ancillary tools, which we all know could be mandatory. Moreover, anticipating that some launches may not succeed, there may very well be an overpurchase in capability. It may not be very gentlemanly, however we’d doubtless elevate costs as nicely. Folks would need to order further machines to realize market share throughout the disaster, and different corporations would search to realize parity in constellations, paying further for that benefit. Think about these results including an additional $200 million in income, a modest improve given the circumstances.
We’d additionally count on further income from powder gross sales usually for the remainder of the {industry}, as utilization charges improve throughout the board and companies refill with further orders. This might lead to an extra $250 million in powder income, relying on what everyone seems to be utilizing. An uptick in orders from companies is anticipated as nicely, as they spend money on new machines throughout these worthwhile instances, doubtlessly resulting in progress of $130 million, about ten % of the standard {hardware} market.
Then, in fact, there could be a satellite tv for pc arms race as new weapons are wanted, and extra satellites that might someway clear up or magically zap away all of the particles. Think about this producing one other $80 million in enterprise. In complete, we’d see round a $1.2 billion increase within the preliminary 12 months. In 12 months two, we might count on accelerated common progress, and this particular circumstance might result in an extra $1.6 billion in 12 months two.
Conclusion
Given the distinctive circumstances at hand, we now have solely a really fundamental estimate. Think about what would possibly happen if the U.S., for instance, compelled corporations to promote inside its borders or commandeered shares. Alternatively, envision if business entities started outbidding one another, paying as much as 5 instances extra for machines to advance within the queue. The query of how swiftly we might ramp up the manufacturing of powder mattress machines stays difficult to reply. It’s troublesome to gauge the extent of panic or the financial incentives that could be unleashed. The U.S. might, for example, allocate $10 billion to expedite manufacturing or present further capital to American companies. Total, it appears affordable to anticipate a income improve of a number of billion {dollars} beneath these circumstances. Nonetheless, do you consider the precise impression may very well be considerably bigger? What would your estimates recommend?
