Why Car Companies Still Spend Thousands On Clay Models | Cars Insider

[@ARZZiO]

Spending thousands on a clay model isn't really expensive for a car company that makes millions each year, plus it helps designers to come up with a better final design so why not

[@Diego.03]

Thousands is just a VERY small fraction of the total R&D costs which tend to be in the Billions

[@ericspda]

While you're still right, these full size clay models easily cost over $100,000 all in. Not sure why they went with 'thousands' in the title, it ain't cheap. And auto makers profit in the BILLIONS, not millions. But the margins are shockingly low all considered, so its less impressive than it sounds.

[@heinzhaupthaar5590]

@@borivojetravica569 There's no proof, but it's absolutely obvious to most who ever worked in design etc. A 1:1 model gives a completely different impression than even the most sophisticated VR programs and such, even without taking into account that you can actually touch the model etc. And the cost is completely negligible anyway.

But it is not a good option for something the size of a car. 1. 3D printers just aren’t that big. You would need one the size of a garage. 2. 3D printers are way slower than human sculptors. I can hand make anything I 3D print far faster than my printer, I just don’t do it often because I can just push a button and then work on something else in the meantime. 3. It would generate a staggering amount of plastic waste. Clay is infinitely recyclable via low environmental impact processes. 4. 3D printing can’t get the same level of detail as a skilled sculptor. Also overhangs would be an issue, and tons of cleanup and refinement would be required.

Sure, you have a budget, but constrained in that, you choose other things. Money is not the end all, be all.

@@exterminator4808 Thanks for your question. The act of clay modelling isn't directly applicable to software development lifecycle, however, the process shares similarities to how non-functional prototypes are made during the design stage of developing software and systems (after analysing requirements). Here, the IT analyst would work closely with stakeholders to come up visual models of the systems using pictures, graphics etc. to show what the end product of the software would look like. Where there are adjustments to be made, the prototype will be easily fixed to align with the stakeholders requirements in order to reduce the cost and time of developing the systems.

I still want to see how a car design goes from clay model to stamped sheet metal. No one ever shows the process of how the actual molds are made.

[@ronblack7870]

huge blocks of tool steel are machined on massive cnc milling machines that can work in 5 axes. heat treatment can be done and final machining then dies are hand finished . look at some videos of the giga texas opening party. they show a die half. it's huge . i would guess 100 tons for 1/2 the mold. it takes at least 6 months to make a set of dies and can cost millions.

[@EatMyYeeties]

Well, the key is in the name. Stamped steel. The mill the design of each panel into massive chunks of tool steel with a receiver for a hydraulic press. They feed in their sheet metal and press it into shape. Now, it's not ENTIRELY that simple. Usually, the mold has to be designed with slightly more curvature in spots to ensure the panel when it is released doesn't spring back to a slightly wrong angle. Steel needs to be bent and shaped about 2-3 degrees extra for it to snap back to its actual shape. This is why many car manufacturers have gone to fiberglass panels as all you need is the mold, and you can lay the fiberglass in and manufacture the panels without the fear of it coming out with an incorrect shape. The only downside with fiberglass panels is manufacturing cost as you need more molds to produce panels at the same rate a stamped steel mold can push panels out.

[@ikannunaplays]

@@EatMyYeeties I believe the part here that is missing and key is how the design gets transferred from the clay model measurement by measurement to replicate 1:1 in order to be turned into the negative mold halves for the press.

[@__-vb3ht]

You use optical 3D scanners or huge contraptions with a robot arm and a small needle that can detect touch to measure tons of points on the model and then those are used for the final computer model. There are different CAD modellers, some build the general file and then a second team will go through and make adjustments of millimetres or less to make sure there are no imperfections in the reflections.

I worked at a university wind tunnel and auto companies would sometimes contract to do aero testing. The clay models were 3/8 scale, about the size of refrigerators, which seemed to be sufficient for aero testing. The models were mounted on a balance system to measure the forces of the wind. Our wind tunnel was the right size for that and cheaper than one that could test full sized cars. The clay modelers had professional art training, and some would make beautiful sketches during the test runs to pass the time. Then they would run back into the test section to make changes for the next set of runs. The smaller models allowed quicker changes than full size. They did do testing on some full-size models at other wind tunnels. The clay was special for industrial modeling with oil and sulfur in it as the binder. It was put on hot and it scraped very nicely when it cooled down. They had a clay extrusion machine with lots of different dies to make all sorts of clay trim pieces. Some of the modelers were of Italian origin. Sometimes they would sing opera in the tunnel. The echos were great.

The key is quick iterative design and being able to make changes in a physical space really quickly

[@zeihnwise4000]

Clay model still stands out in 1:1 scale over 3D print and/or VR models main reason is that if you want to make some changes or modify the surface, you can do it instantly on the spot, easier and more efficient (sanding plastic parts is pain and the dust is hazardous, while it is hard to modify miniscule changes in 3D model VR like mentioned in the video) other aspect is that, compared to 3D printer, clay model is way quicker to execute and finish, also cheaper (both materials and time-to-cost aspect) (excess clay/the model itself can be recycled and reused instantly) if you ever handled 3D printed parts then you must know how "smooth" the surface is, yes? applying chemical on 3D printed parts to smoothen it will also smoothen those supposedly sharp edges details :)

[@xnadave]

CAD and the other tools we use can easily get in the way of the design process. Being able to iterate in seconds by adding or removing material is invaluable.

[@christopherross8358]

Sometimes I really hate CAD, especially when the company you are working for forces you to use a particular software you really don't like. I love building by hand and making molds. It allows me, mostly, to produce a field ready beta. I do like Cad for sub assemblies and gears - and regularly print out a STL or OBJ and add clay to it when making enclosures and cases with inter connecting parts.

You're not supposed to work on modern cars. You're supposed to bring them in for "service" where they either have specialised tools or drop out the whole engine to do minor maintenance or just replace a whole module so they can charge you an arm and a leg. That's where the profit is.

@@theaveragepro1749 the idea is to mock up an engine bay with 3D printed parts and test the ability to use tools and hands to get to the most common components associated with maintenance and repair. Vehicles are now built from the inside out AFTER they are designed from the outside in. This lead to vehicles that once they begin to break down become too expensive to repair and thus end up in the junk yard after only 6 years.

It wasn't really mentioned in the video, but I'd also imagine it would be a lot easier to collaborate on a physical design than a digital one. You can have different people, with different skillsets and abilities, working on different parts of the car simultaneously. Obviously you could split a car into different parts and have people collaborate on that digitally, and perhaps even sync it up in real-time in the viewport, but physical is probably far more flexible in that regard.

I love having an official come out to say "yo it's just not the same" It sounds to me like the only part of this that wasn't actually possible with a digital render was the wind tunnel, and even that is something that physics simulations are going to continue to improve with. Other than that this whole video feels like a bunch of people going "I really like it and it's what I'm comfortable with", which is a totally fine answer, I just don't understand why they need to pretend like "there's no way a computer could adjust the model by a millimeter"

[@1000percent1000]

they didn't say it's a computer problem, they said it's a machining problem. going back to adjust a part requires that the part be in the EXACT same place it was before, otherwise the milling bit will just ruin your part as you try to fix it. definitely agree with everything else ur saying tho, this was a pretty bizarre claim

[@slome815]

Digital imaging had a big problem with scale. While you can see if proportions are righ,. It's very hard to get a feel for how large or small something really is. Make every part on a digital model twice as small, and it will still look exactly the same, by just zooming in a bit. We had this problem with an engine model one of my students was making from plans in imperial units. It looked fairly large on the screen, but once you started measuring it turned out it was a really a couple of cm's in size overall. Also, and I guess the techbros don't really get this, but sometimes it's just faster and easier to do things more manually. If there is a one of fairly simple part with a lot of fine engineering fits it might very well be a lot faster to turn in on a conventional lathe then on a CNC lathe. If you need small changes visible, with accurate lighting and shadows, it might very well be a faster to just make the changes in clay first to visualise if they work.

[@__-vb3ht]

I'm no big shot official, I'm still studying car design but I already have a degree in clay model making. You perceive things really differently if they are on a small screen or as orthographic sideviews vs. when you're standing next to them, moving around the object. It's hard to describe but a screen can't portray the proportions or size of a car exactly. VR goggles are quite good but they still don't beat the real deal

[@lcusatis]

[@vv.1918]

It’s the same concept on why we don’t have an actually accurate flat “globe” map. You can’t take a 3 dimensional sphere with details on all sections of it and make it into a square map. Or even a round flat map. Even though we live in the 3D world, and inter act with it, we still do not fully understand how to take a 2d object and make it 3d flawless without some adjustments.

[@gotlos1]

Basically, to give you the full rundown in as short a time as possible: Double triple-check every part of a design. Touch is a much more sensitive perception than view.

[@christopherross8358]

Clay is my favorite material for developing prototypes and product designs. I like using Plastalina, and then making a mold and casting a wax or in mineral resin. Don't get me wrong, I love 3D modeling - but many times you get the right proportions and beautiful subtle details when you've worked it by hand. Also, clay sculpting is a sensory skill. Many times you pick up on the details of your form that your eyes become useless and have to feel it out.

Makes sense that a 1:1 model would be needed early in the design process, and one made of clay is probably as easy to modify and affordable to completely redo as they can get right now. I’d be interested to see if some type of extrusion technology will supplant this in the coming decades. Even then, I’m having a hard time imagining it being more affordable or easier to work with than clay and CNC.
