- The world's first 3D printed stainless steel bridge recently opened in Amsterdam. The bridge is the brainchild of MX3D, a Dutch company that has developed a proprietary software to turn an ordinary welding robot into a high end industrial 3D metal printer.

Plans for this bridge began 6 years ago, in 2015, when MX3D proposed 3D printing a metal bridge on site. They developed several design concepts, and got the support of Autodesk and the city of Amsterdam. After finding a location in the Red Light district, they scanned the site and created a highly detailed digital site model. The scan helped them develop edesign constraints like dimensions and strength of medieval canal walls, the limits of 3D printed steel, on-site assembly, city regulations, and engineering and practical limitations.
MX3D and Joris Laarman tried to use the same volume optimization approach in the design of the bridge but it failed. So they teamed up with engineers at Arup on a sheet-construction approach.
Stress analysis software generated force lines through the bridge. Since the bridge heads are not aligned, the shape had to be asymmetrical. They had to also scrap the idea of printing it on site because of safety and technical concerns. The eventual design shows off the capabilities of 3D printed metal technology.
They developed a software called Metal XL. They call this printing method robotic wire arc additive manufacturing technology or WAAM. A 6+ axis robot and a MIG/CMT welding machine creates pieces by depositing metal layer by layer. Although this bridge was made of stainless steel, they can also print in carbon steel, duplex steel, aluminum and bronze. Even though the walls of the bridge are thin, the overall shape makes it strong. The bridge measures 41 feet or 12.5 meters and weighs 9,920 pounds or 4,500 kg. The actual printing process took 6 months, and was completed in 2018. When it was ready to be installed, the bridge was cut up into 3 parts and transported to the site on barges. The pieces were lifted by a crane and welded together on site.
Scientists at the Alan Turing Institute, IoT specialists and engineers embedded a sensor network into the bridge and created a “digital twin”.
While the design itself isn’t biomimetic like the Bone Chair, it has a unique futuristic language of its own. It’s a statement, a piece of art, a hint at the future of 3D printed designs. I think that it is so drastically different from the vernacular architecture of Amsterdam’s Red Light District, that it works. I love that they didn’t paint it or powder coat the steel, they left it honest and raw. The team also claims that the bridge is hyper-efficient and uses minimal materials.
Nicolas, who is a part of our TH-cam community, recently visited the Netherlands and experienced the 3d printed bridge. He said that the layered print and welding is crude and uneven. It’s not as sleek as it appears to be in photos. He also said that design does not take the directionality of the layering into account in the way a concrete bridge does. The layers look arbitrary which is an excellent observation. Nicolas also said that the curved hand rails are used as a trash can by people passing by. This is why humans can’t have nice things.
Lastly, there’s a significant misalignment between one side of the bridge and the pavement. They tried to fill the gap with brick pavers, but it looks very sloppy. I think we need to understand that this bridge is an experiment. It’s a rough, first iteration in this exciting, new technology. It may be more expensive, and take much longer to produce right now, but it has the potential to change the way we design and build in the future.

If anything, A temporary structure is the *best* place to try a new building process. You get real world feedback and its not expected to be there long. I guess its a good way for a company to off-load some of its iteration costs while working to make a product truly market ready.
I wish more people can see this and see while 3d printing can be cool and impressive there will be pros and cons with it and this demo can really help show them.
It's also handy because in the decommissioning process you can identify any real-world problems that arose.
There's an issue with liability though, I doubt it will catch on because companies don't want to take the risk.
This is just a marketing gimmick, nobodies going to be 3d printing a bridge unless it’s an art project
@@mopslopmop That's valid for any engineering, so apparently, engineering companies don't exist.
The best Architectural channel. Objective opinions a real slap in the face to bring us back to reality
Thank you!
@@BelindaCarr so grateful to have found your channel! I really appreciate your perspectives. Very grounded and balanced 😸👍👍
2 steps forward, 1 step back...growing pains...Thanks Belinda for another educational video. You Rock!
Great overview, I believe what you mentioned towards the end was that this was an experiment, not the end of the journey. It's always important to look at failures or semi-failures as opportunities where we can all learn together which is the message you conveyed. By the way, it was great listening to you at the Summit in Austin a few weeks ago; it was very informative!
@@WinstonSmithGPT We see failure all around us and that is how the market moves forward, someone is tired of something that doesn't work now but might have filled a gap in the past. It's called, "Fail forward Fast" which is the driver of product development.
Running a welder for 6 months must have consumed a fair amount of electricity - is that included in the embedded carbon estimate?
@@joechaos13 most of the gas in the shielding gas mix for SSteel, would be argon.
We did a quick calculation of the whole business case for our design students... space, several robots, welding wire, inert gas, electricity, wages... it was absolutely abysmal from, both, an ecological as well as an economical standpoint, not to mention engineering issues. Really, nothing to brag about...
@@dragonrider269 if you mean 90% helium mix then it's even more expensive.
Nobody cares about "carbon footprint". We have nuclear energy to produce cheap electricity.
Carbon footprint is a communist hoax to empoverish and tax people with the pretext of "saving the planet".
We definitely need to get artists, engineers, and city planners to talk more. Something done by only one us either ugly or your hand holds end up being garbage cans.
Then we need politicians to listen to them instead of lobbyists.
I visited the bridge yesterday. It’s an amazing structure and for me it’s a new word in architecture, but it is also an experimental work and we cannot expect it to be perfect. There is a problem of connecting one side of the bridge with the pavement - you can really look under the bridge between the ground and the walking surface from one of the ends to see the sensors. It leaves a very good impression.
Thank you for the video and multifaceted view on this event.
I just was there this morning during my stay in Amsterdam. The bridge looks amazing, and yes, a little bit out of context, but still an interesting and beautiful piece of tech
Considering that the project took six years to complete, surely someone must have seen that the structure was too big to be installed in one piece. The design should have taken this into account, and a sectional design created that would slot together on site. I am also rather underwhelmed by the solution to the mismatch (for which, in the age of GPS that can register a site in 3 dimensions, I can only assume was extreme carelessness) at one end of the bridge. There were many ways that the difference in levels could have been dealt with, but they seem to have chosen the worst solution, which not only fails to be wheelchair friendly, but appears to be dangerous.
Concept: 8/10
Design: 7/10 (they do look like waste bins!)
Installation: 5/10
Question is how much energy did it take to build a bridge out of welding wire compared to more conventional steel production.
I think that was included in the total carbon footprint of the project. But we don’t know the carbon footprint of a normal bridge to compare it to.
Considering it was only meant to stay up for 2 years, and that it's such a short crossing, I'm certain that a wooden bridge, or even a bridge with a couple of prefabricated metal girders cut to length with a wood deck on top of that, would have been vastly more energy- and carbon-efficient.
@@killerbee.13 recycling existing steel girders with a sustainably sourced wood deck would've been the best option for a temporary structure. Infact, the crude look of it would've made a statement about needless opulence in modernist design.
@@ecospider5 -- Well, about the same amount of "carbon" is used to generate one ton of structural steel as on ton of wire. But then the wire has to be processed one more time to make the structure. But this is more than a bridge, it's a civic decoration, albeit a temporary one.
@@GilmerJohn "Kinda" because to generate a complicate, organic and/or minimal material usage structure the alternative of 3d printing would be casting, so remelting the desired metal.
Steel without heat treatment is a top ingredient for structural failure
Well, at least it's not brittle, it won't break with people on top, but bend over time instead (or at least that's how I think it'll happen)
most structural steel is cheap mild steel and isn't heat treated, even the hot-rolled stuff is cooled slowly and carefully
it doesn't need heat treatment. the clue is in the process.
The bridge is amazing. I've been waiting to see its completion. The production process is a snapshot of what's to come.
Bravo!
The bridge looks ugly and ruins the surrounding area, but looks kinda cool on it's own
The same could be said about any architectural innovation until it reaches a tipping point where it displaces its architectural predecessors.
except that's just your personal, subjective view. in reality it compliments the existing urban fabric through contrast and juxtaposition, in both form and material.
Awesome video, as usual. Thank you so much, Belinda. You are so ambitious and so well informed. To me, this is a totally new variant of 3D metal printing. Hints an exiting future for emerging methods and tech concepts in the building industri.
That's beautiful.
There is a company printing rockets as well.
We are truly witnessing the future of construction.
I love you always point out wheelchair access. as a disabled wheelchair user, I'm always dissapointed when I am left out of a space due to inaccessibility. I love when nondisabled people value access for all and call out inaccessibility whenever they see it. thank you ❤
I always appreciate the depth of your content. You can simultaneously appreciate the overall experimental objective and also acknowledge that in detail there are still obstacles to overcome to make it practical or sustainable. You avoid the usual media binary stances such as "this is the greatest revolution in construction" or "this is a horrible scar on the Earth." You truly are an architect, reasonable, informed and artistic.
jumped on the bridge a few times when it was at a test location, feels solid and has a very raw look.
Your videos are by far some of the most unique TH-cam content. Thank you for producing/publishing/etc this stuff.
I would love to know more about why the biomimicry design failed, sounds like that’s a software issue where the software wasn’t able to get to an optimal structure?
If anyone has additional literature on why that failed I would love to read it!
I don't know, but I suspect that changing actions from wind loads and the complexity of the structural response meant that the design was so non-linear they struggled to make a stable and computationally efficient algorithm. Either that, or the design requires hollow sections to achieve an acceptable efficiency and this is beyond the capability of the biomimicry software.
@@alexandersime-scott8198 that would make sense, I presume most optimization systems assume a static mono directional load ie: gravity. It would be rather complicated and computationally expensive to extend that to dynamic changing loads like wind and understanding resonant frequency modes.
My initial guess was well if it works for a chair why wouldn’t it work for this, but that’s definitely a decent guess. Still that seems like a very promising method for the future.
@@FreekHoekstra my thought was, it was just too complex to print?
@@richm1981 given they can print a loose filament, I doubt thats the constraint, but maybe...
My guess would be that the strength-force ratio was just too far outside the capabilities of the software they had.
I really love that you showcase the negative as well as the positives.
It’s a massive step forward and is a beautiful contrast
‘A hint at the future” I love that 👏🏻
Jinkies… Couldn’t print it on sight; nor, install it in one piece?! The press really has made more of this than it is. I can’t believe they had to CUT it into three pieces! We are not there yet.
Look, at least it's an entire bridge that had been actually printed. Not "well, you see, it's just this part of one wall of what's otherwise a pretty standard design and a fully printed prototype with some minor issues like huge cracks..."
@@nebufabu Agreed 👍… more power to the next gang. Whoever was coordinating this missed in the last. Why one piece when two interlocking ones might have been easier to ship and install.
In the tile world, they’re making 48 inch squares… Why?
@@StephenRansom47 nobody missed anything, the objective was to print a bridge in one piece - objective achieved. then the issue of installation, a separate problem requiring a different solution.
I'm mostly impressed by how they've implemented the sensors to be able to detect how stress forces are applied, being able to detect in real time the health of a structure is pretty cool.
The 3d printing aspect is an interesting test and probably one that's needed to be able to develop the technology further, but I cant help but wonder if it would have been more efficient to try to grow bamboo to shape
Strain gauges are very easy to install on most structural steel. It's actually a very common thing to do.
Whoa, this is so darn cool! I'm so glad I found this channel!
Another great overview. Loving the vids.
They compromised the test by dividing it and welding it back together as it creates a stress riser not a part of the original model.
I thought about that as well. But I guess there was no other feasible way to transport.
Or, who knows. Maybe they factored that in after realizing that it had to divided to transport
@@jonl8816 Mhm if it was part of original design, why not print it in parts to begin with? They would have calculated that even cut and rewelded, it would be fine.
the cutting was the one thing that bugged me. but properly executed welds are generally stronger than the parent metal, so not a stress riser.
The object itself is basically just one enormous weld.
@@garethbaus5471 exactly.
This is really cool, I love your takes on technology like this, its really cool to get excited and not feel like I've been 'taken' by the marketing for it
🖤💜💙💚💙💜🖤
11/10 love your channel!!
Thank you for this Belinda. When thinking about 3D printing this is not a material I thought of.
I really appreciate you, and your content… and though i am not my self an architect , i feel like i am gaining access to some of the knowledge, terminology, and thinking methods of architecture. Thank you
Insane, TX for upload video like this😀
The bridge that replaces it and was briefly seen in your film was in itself a temporary replacement of an older bridge.
The quay wall has been replaced in the meantime and the old one also had several steps. In the old situation, it was also not wheelchair friendly, but about 200~300 meters to both sides are bridges that are wheelchair accessible. And I wouldn't be surprised if they adjust the street to it in the coming time.
Also, not a single house in this street is wheelchair accessible. Everything is from 1750~1850, many stairs, everything narrow and steep.
A cynical thought is that if you use a wheelchair, you probably aren't going to be able to fully enjoy the red light district anyway. ;)
Perhaps the six years of effort would have been better spend on developing a better wheelchair. One able to cope with the challenging Amsterdam environment.
WOW! GRATE presention! Clear, consise, brief leaving me wanting more!
Sounds great! Can't wait to see a replicated building.
A very interesting video! And a wonderful concept for bridge making. Who knows what's possible in 10 more years or even less.
Such a detailed video!
Installing sensors and monitoring is smart. All infrastructure should include this. No reason not to. Very cool collab that became reality.
Re the badly fitting ramp: When I hear that the bridge had to wait several years for installation because of renovation of the embankment, I think we know the cause why despite scanning the interface first it did not fit.
On the critique of the inorganic layers: That could be addressed in the slicing process. The robots are capable of laying down the layers in any form. No need to slice in the geometrically simplest way doing plane cross sections.
But it also makes me wonder how much it may have warped as a result of production method? During printing, some material tension gets locked within which can later cause a warp. But indeed the installation spot changing in the interim is the most apt explanation, also considering they were worked on in the interim.
Thank you for sharing
I tig welded stainless steel for many years, this seems like a huge waste of electricity, argon and carbon dioxide, but it is artistic.
Argon seem like an excessively expensive choice of shielding gas on a big project like this.
Exactly....and how much would the MIG wire cost....in Australia a roll of 4.5Kg is a weeks wages....And if you start with a kilo of wire....how much of that is effectively deposited...how much is vaporised ?
good video. Thanks for making it
As an experiment it’s super successful it really gets the gears turning. This makes me think about the “site to software to site” workflows where the techniques are heavily driven by software that experimental and heavily emphasized but the site overlooked (or in this case mismeasured!). I hope to see another project come along where the can actually print(weld?) on-site.
I agree with your site2sw2site POV, it would make the argument that a dummy/template/lightweight shape could have been printedn and placed into position to confirm exact geometry, so that fit issues could have been found.
I think it looks incredible.
thats so wonderful!
Building materials and design suggest use whether or not the designer intended that purpose. Use a soft material, and people will carve it. Use an accessible flat design with material that holds paint, and people will paint it. Make a bucket shaped design, especially in an area with inadequate waste disposal, and people will leave their trash in it. Another example... the engineers who designed the refrigerator wanted to use a cheap sturdy material for the outer skin and placed the device in the kitchen. Combined globally, these surfaces display a thousand times more square meters of art space than all the art galleries in the world.
Cool project, beautiful design! The Dutch again… 👍🏽😃🧡 and very informative video - thanks!
Finally an objective point of view about that 3d printed object. Good stuff.
I was is Amsterdam last weekend but was unaware of this bridge hence I missed it😐 Will check it out next time thought. Thanks Belinda, for pointing it out and explaining it’s story!
Belinda great video! I want to visit this place soon!
This tech holds so much hope for me… my first sight of it back in the day, brought tears…
I think the tech is best used to put materials into a difficult shape, like the original patient, then shape or tool it into the final. 3D printing should join the family of casting. From a sand cast to extruded to injected to “whatever they call” this… stacked? Like everything else in manufacturing, just another way the get at a product. Closer to the winking-of-an-eye.
PS - Perhaps the use of multiple torches laying down the same line… one behind another… will speed things up.
3d printing seems like a reasonable replacement for castings on weight sensetive jobs.
A lot of the canals in Amsterdam are approximately the same width. They may move it around to rebuild other bridges? To me they should have fastened the three piece back together rather than welding since it not truely "3D printed" at that point anymore as one piece. Looks better than some temp metal scafford type deal. Reminds me of a rough old cool car- looks great from a distance but upon closer inspection, well you know. Like that it is full of sensors. They where really committed to seeing this project though! It's cool!
There was an old welders joke:
If the welded seam is stronger then surrounding it material, why don't we just made it whole out of welding.
I'm glad these times are already here )
Yes, pretty modern architecture!
2:07 and you can BET that the part where it printed the report is the one that jammed more often
I like the wobbly form as the location is mostly visited by drunk tourists.
Ha ha! I was thinking along similar lines. Seeing as the people using it will probably be exiting the red light district. ;)
I'll refrain from posting my actual opinion, but this seems like a solution looking for a problem and in the process finding it's own problems let alone the terminology mismatch. It's a CNC welder to be sure. I face palmed hard when they "printed" the bridge in one piece then cut it up to get it on site. Seems like this was a "sure you CAN, but should you" moment.
Looks pretty cool. Turned out much better imo than the original concept.
Pretty cool for a first experiment.
Nice!!
looks art nouveau this bridge, very cool
Can you advise us on what software we can learn for 3d printing as their is big scoop in future in civil engineering
This is not 3D printing, it is robotic weld deposition. Your reference to the 1925 patent outlined the overall process. In this case deposition is optimized by real time weld quality monitoring, and the deposition of SS material is optimized by detailed stress analysis. Otherwise, thank you for producing this excellent video, 7 minutes chock full of good points.
Another interesting post, I appreciate how you present these and the questions you pose and ponder. I wonder if the fit and finish would have had a better outcome if they made functionality the top priority over making an artistic statement 🤔???
I love the idea. Well done my friend. Please come to Asheville, NC and Couchsurf with us!
It would be nice to hear what went wrong with the fit🤔
I just keep flashing back to the old saying "Just because you can doesn't mean you should".
Really good and interesting reposter.
It's very pretty
Wow. I had many beers at that bar, de stoof. They have a cat living there! Awesome video, I must visit Amsterdam too
Very informative video. I didn't know this tech ique was being applied outside of the 'lab'. It's surprising to me that despite of having photogrammetry models, the bridge didn't fit at all on 1 side, but I guess that's why we do experiments like this in the first place.
The next iteration will be better, then the next even more, etc.
During the time the bridge was getting built, multiple embankments in Amsterdam suffered a total failure and collapsed. These accidents were looked into and revealed ground material that had been washed away by the tourist boats at some points because of the tight turns they need to make in some parts of the canals, causing a lot of erosion.
One of the biggest collapses also made it clear that due to this erosion, some embankments might not be safe to drive heavy traffic on anymore, and some saw emergency repairs to mitigate this as a result.
I'm fairly sure this is part of the problem.
(Next to that, this is The Netherlands and at times, with all our rule- and normbooks on how to desigin public spaces we tend to make dumb, costly mistakes that sometimes are near impossible to fix).
Wonder how they got rid of the slag or does the welder just burn through it?
I knew they wouldn't build on site the second you mentioned it. TH-cam stopped suggesting your videos so I get to catch up on your channel.
The technology itself makes sense.
Maybe for construction site less, for for sure for manufacturing.
I will allow longer lasting cars etc., as right now plastic is used in the working environment they destroys it.
Saying that, this bridge is a piece of functional art.
Bones are not the "most efficient" structure. They need to have muscles attached to them and move. The taller the cross section, the most resistant it is to bending. This bridge illustrates that.
As always, great content :)
Excellent video with both positive and negative feedback.
It does look cool. But it is a learning experience and that helps move technology forward.
Cool bridge
oh my, you know the creator of the bridge did not like having to cut it into pieces :)
For sure! I know I winced when I heard that!
probably knew it was coming.
@@daos3300 if he knew it was coming, he would have printed it in pieces :)
@@ArtisanTony no, since the whole point of the exercise was to manufacture it in one piece. goal achieved, next problem to solve - installation.
@@daos3300 The main problem was no one properly planned the project. I am a design build contractor. I would never design a system with such mistakes. If you design a bridge in one piece, you have to confirm transportation and installation before you print it. This is the typical failure of "artists" to understand project management which is best left to someone like me who is use to getting things built in a proper way.
I’m surprised it’s so unrefined. Definitely an interesting piece though 👌
Thank You. I think that adative manufacturing has a lot of potentul . will it replace everything everywhere , no but I believe that there are a lot of places that will work better
I remember seeing a 3D printed bridge made by a robot welder maybe 5 or 10 years ago. This might be the first regulation-compliant 3D printed bridge but it isn't the first.
The misalignment is very common in the physical construction world. It would be great if we could get away from this but it is amazing how often our perfect plans don’t actually match reality. My wife worked for a company that had to fix a huge project where a bridge missed the final footings by 3 feet. I never saw their fix.
One more reason to visit the red district ;.P
Futuristic certainly but it also reminds me of Art Deco. A compromise to reduce the carbon footprint and avoid layering might be to *3D print very large molds* for metal casting which would no doubt have it's own challenges.
Incidentally *Relativity Space* are using wire welding to 3D print entire *stages for rockets* althought it's still a work in progress.
What would theoretically protect such a bridge from rust? It's not coated or galvanized. The handrails and floor plates, with regular contact, should remain polished, but wouldn't the other parts rust fairly soon, especially with this being above water?
It is stainless.
I doubt any of those curves are actually doing anything structurally. An I beam with a few plates welded to it is probably lighter and more structurally sound.
doubt it. and that's not the point, is it.
Hi, can anyone please tell me if this bridge is still in place ?? Because I read , it’s was removed .. 🤔 thank you
Miss you video's Belinda. I hope the house improvements are going well.
Kinda mimics Art Nouveau, maybe H.R.Geiger too. Not my aesthetic, but I suspect eyes will too busy window shopping in the red light district. 💃
I've heard of a 3D-printed home. I wonder how cost-effective they are, if at all. I wonder how liveable and safe they are.
I must say that I love your channel.
Thank you!!
What I don't like in this day and age is that people expect perfection out of the box and will criticize its flaws even though it's an experiment. However this has been going on for years, it's just back then people could get away with alot of stuff, now social media will tear it apart.
But then people are hypocritical. They want perfection, then they purposely create content that's imperfect (memes).
Nice vid.
The bridge looks beautiful. Certainly a lot nicer than the previous one. But I haven't seen it close up.
Very cool progress on the concept of autonomously.erected structures. Set it and forget it construction is the end goal, obviously. But realistically we’d actually be going for accomplishing construction with minimal oversight.
So there are several neat ideas to build on with this.
One is large composite structures are potentially possible like this. And potentially can be done very precisely 24/7 if you work out out the programming and best types of robotic and tool designs to accomplish it.
Now, all that is only so interesting in comparison to prefab, and construct on site. Show you workers the screws and hot the parts fit. And where to weld. Convenient. 3D composite is still very cool, because it can potentially build structures you simply couldn’t make any other way, but still needs a lot of development to make that truly preferable to other modern methods of construction and design.
The real interesting possibilities are in sending out an couple machines to scan and assess, and build off of whatever the controllers deem best for that. With little oversight. The reason that’s interesting is because the amount of work you can do becomes more about how much machinery you can send out. A dozen work crews across a city is absurdly difficult to put together when it’s 30 or more guys, plus all the heavy equipment. Shrink the crew size, and build sustainable semiautonomous heavy equipment, and you might find that even if it’s as expensive, it’s over all a thousand times easier to oversee. A normal construction crew is a lot like herding cats. That’s not an issue in leading robots. They don’t show up to work drunk, act like giant arseholes to each other, or take any.time or effort to vet for the lazies, stupids, or addicts.
The obvious issue is that you’ll need to develop a lot of new software and hardware, and bring in experts to assess the issues of construction. Additionally, construction sites, and ground conditions are a huge issue for a band of monkeys in hard hats to deal with. And they are built to navigate difficult terrain, and inclement conditions. So you’d probably need to develop methods of isolating terrain, so you can control as many variables as possible. Think like you see in city reno. With the scaffolding and plastic. Plus excavation and infrastructure is its own hairball.
However. This solves a couple of those issues. If you just deliver the machines and wire for a large portion of the structure, you can cut out a ton of manufacturing. And if you get really good at understanding the area and blueprinting with cad, you might end up making types of structures, and in places you’d never imagined doable with less consequences for taking your time in development. Machines with some standard storage and Maintenace can sit it their crates as long as you need them to. Where as live labor has literal hosts of needs and desires that change the costs of their labor.
Plus the best part. As long as you don’t lock innovation up, like Disney does it’s IP. That is into perpetuity. The more you use the systems, the better data you have to develop across all work done. Innovation is more or less directly applicable across all machine language, and the methods and systems used to deal with circumstances of construction are also more or less applicable to any other operation in that field. Where as with more people the systems more or less dissolve as the workforce loses and gains new highly variable individuals. The engineers and architects are developing. The machinery develops, but the workforce is constantly changing. And good workers, and good leaders are the limiting force there.
Anyway. Hopefully that was semi coherent.
Why this and other of Ms. Carr's videos only receive 173K views is very telling the society we live in. People much prefer watching cat and dog videos.
It's an experiment. I fully support the attempt with all of its flaws.
A similar discussion pops up with hobby 3D printing. Some people are concerned with all of the plastic being wasted on knickknacks, failures, and other junk. And as somebody who is extremely concerned with plastic recycling (I've been recycling plastic by hand for over 9 years) I feel the rapid innovation and decommodification of inventing is fully worth the amount of plastic we're spending on it. Especially when compared to the absurd amount of Plastic wasted by industry.
I'm still trying to find efficient ways of recycling 3D printed plastic at home but I think 3D printing as a whole is beyond defensible.
That was a very interesting respones. I've thought about keeping the wasted plastic to a minimum in the same way that you do. As a result I tend to combine working with wood and 3D printed parts as much as possible.
I must say that I sometimes see people print models that would've been finished in 5 minutes with some basic maths and marking skills on a piece of wood, instead of the almost 60 minutes it took some people to make some marking helper for whatever project they are making.
Personally I'm more concerned with how plastic (whether consumer-created like with 3D printing, more or less or industry-created) is recycled.
One of the problems we have now (that we are seeing plastic absolutely everywhere) to me is the same kind of thing that caused the electronics industry to switch over to lead-free solder and to me would be as undesirable a solution as lead-free solder (I am thinking of bioplastics and that kind of thing that, while, yes, being biodegradable might be good, can cause public opinion to sway back to "It doesn't really matter if I throw it out on the street", just like waste facilities tend to not like bioplastics in regular plastics (We have separate bins for plastic and regular waste in The Netherlands) because the bioplastics do not recycle as some of the plastics out there and as a result can contaminate them).
If we would actually take care of recycling our electronic equipment in our own country instead of shipping it off to who knows where just because it's much cheaper there and the worker protection laws are non-existent, we would not have had the problem of lead contaminating our soil as much as we do or did.
@@Dutch3DMaster I think you might like the stuff I'm doing on my channel Inventtory. I recycle plastic by hand using stuff you can get from any hardware store. My videos are terrible but I've been working on my methods for 9 years.

How much energy was needed to weld it together? 🧐
I am a welder and CNC machinist, 3D printing structures like this will never be economically viable for large products.
This is because when you print with a welder, you are consuming an absolute ton of electricity, so the process not only takes a long time, but it is energy intensive.
Where I can see this technology working well is in creating joinery where you have to bring several pieces of structural steel together, and need a strong fitting developed in a certain way to bear the load.
That's Green-washing. Make the bridge from 3d printed carbon-free steel and I'll be impressed.
