this guy, Gabe Bentz, recited "design for 3D printing" so many times on his Slant 3D TH-cam Channel that it "burned" in my mind - every time i design something now that goes on my 3D printer, i keep this paradigm in mind and ever since i do it that way, i save so much time thanks Gabe
It may have been a boring Ted Talk for those that have a background in manufacturing or 3D printing, but as a beginner, this was a really great Ted Talk to listen to.
I'm just getting into 3d printing molds for silicone casting medical task trainers, Slant 3D has been such a help with the amount of information they share. It's awesome to see Gabe's passion for helping continue to this day.
As he said: A kid can just create a model over a weekend, post it on the internet and say "If you want it, buy it."....that´s just so true...Thank you, this was worth watching
Got a quote from these guys last during the winter, not bad pricing, but here's the big problem with this concept of quick manufacture: most products are not only plastic so you need to assemble extra parts and also package the item. So whereas yes, you can manufacture plastic faster, it's not cheaper and you will have the extra expense of assembling and packaging. Plus, Slant wants to build a whole bunch of units for you and ship them, thus building inventory anyway, which defeats one of the biggest benefits of 3d printing: very low inventory.
2 days ago I designed a simple product in CAD. Yesterday I printed the first prototype. Made a small change and printed some more. Today it’s on my website and I just sold 40. Small beer but what other technology could do that?
I used to have a couple CNC machines (lathe and mill) in my garage. They definitely could do that, and probably 10 times faster. They're also big and heavy and power hungry, and you need a large garage / workshop. 3D printers are becoming better and better, and they don't take up that much room.
A point that I don't think that I quite hit home in the talk. 3D Printing is actually cheaper than injection molding up to around 25,000 parts, since the cost of the mold is eliminated and the material cost is low for a large printer farm that can operate at scale. It truly is a manufacturing technology for producing large quantities of items at scale.
Bondy Getting your mold or design wrong is 1 time cost. The cost is roughly = (DesignCost*FailureTimes + ProductionCost*NumberOfProducts) From my experience, failure times in design is about 2-5 times. So if you produce 1 million products, this is negligible.
Bondy Sure, 3D printing reduces design time. Again, this is 1 time cost. How about the failure of 3D printing? If you print 1 million parts, you multiply this risk by 1 million. From my experience, 3D printers aren't that reliable. All it takes to ruin a part is 1 second's random error in 5 hours printing. Assuming you have 95% success rate, 1 flawed part in 20 is not acceptable beyond prototype stage. There are also invisible flaws like poor layer adhersion. It looks fine, but snap it along z-axis, and it falls apart. Even if you figure in the extra material cost, how about the cost of quality check? Either you need to hire extra staff to do quality check, or develop machine learning (very very difficult) for every type of product. From my experience, even when 3D printing can theoretically print almost anything in 1 run, it is better to keep parts reasonably small to reduce the failure cost. In mass production, this basically nerfs its edge over molding in terms of simplified design.
Bondy 3D printing surely has its niche, but don't exaggerate it. Pretty much anything additive process can do, subtractive process (e.g. CNC) also can do. With a few differences: maybe you need a few screws in a subtracted parts, while added parts are rough and weak, but lighter. CNC has been well used for ages. Even if it theoretically can do everything, it is not *best suited* for everything. The same goes for 3D printing.
Bondy I'm sorry, but this is a really slippery slope. Mobile phones 40 years ago did not have a fraction as many functions as modern smart phones. The only things they have in common are they both can call people at a distance without a wire, and called "phone". This is an example of how a word evolves over time, but describing different things. Maybe 40 years later, a 3D printer has a quantum computer, a smart phone, a chemistry labolatry, a lot of robotic arms, an AI that designs models for you and talks. Yeah, at that stage, it would be a true comparison to "phones". I never said 3D printer is a "fad". It will surely survive, and have its niche use, just like molding, CNC and so on and on.
Need more info. Who assembles the parts though? If you sell a toy, and let's say it moves out of batteries, or a physical momentum of some sort (let's say a spring inside), what is the work flow between the designer and the buyer? Is the customer be the one to assemble that based on the instruction manual. Also, I think a prototype is still much needed before any release in the market, really, even if it's 3d printed.
I own a small farm and sell local in my town for now until I eventually get enough printers to launch nationally online, I am not disclosing my main product as it is not even searchable online and I have yet to trade mark it however it requires circuitry and part assembly before finish. I am the one who sits down at a table and pre-assembles all of my products for a customer before they receive it and if it breaks that even better for me because then I can charge a repair fee for replacement!
Well, 3-D design and print a carburetor which turns alcohol into a perfectly mixed air-water vapor, fits under the hood within the required emissions system, do it quietly so nobody knows about it, and figure out a way to keep paying the fuel taxes to hide it, and enjoy the benefit of 85mpg or 125mpg or whatever you can get. Or 3-D design and print a device to split water using RF energy and just use the hydrogen, and spend the time to hide it within existing required emissions devices and fuel tax record keeping/paying.
alcohol-water vapor, not air-water Also there was a fellow years back who reported a carburetor which used parts like an air conditioner does, to turn alcohol liquid instantly into vapor, and got 85 mpg in a big boat car, as well as 8 years in prison with no due process and no record of it when he got out
how long does it take that 1 person to change 100 rolls of filament? how about if there is a 1% chance nozzle block per hour? or 1% platform misalignment after a day of nonstop printing? I don't believe 1 person could maintain 100 units.....if nothing breaks, sure. But when smthing happens....it's a nightmare...
its very reasonable for one person to maintain 100 printers on a daily basis. nozzle blockages are extremely uncommon and can be easily fixed most times, even if it did happen, 99 printers would still be functioning while it is fixed. filament changes take under 30 seconds, meaning 100 printers can be changed in under 1 hour, which would not all happen at once anyway. platforms don't just "misalign", and if they do, it is easily fixed. 3d printers are pretty easy to use nowadays, the difficult, time-consuming part is the constant upgrades and tweaks hobbyists like myself so often do.
@@lukecunningham8793 they are easy to use! but to print consistently throughout is difficult. I can't remember how much time I spend tweaking slicer settings, adjust speed, print bed, temp etc. Sometimes just because it printed nicely the 1st time, it doesn't mean I'll print the same in the next 10. Now you multiply that by 100 printers, even if it's the same printer model, but the end product won't have the same quality. What you need is 1 machine capable of printing at a speed that is equivalent of 100 printers. So that you get some consistency. I personally don't think multiply the number of printers will give you a consistent production line.
The price is no a problem, because your product is intent to be purchase by someone how don't know how to model in 3D and do no have time to manufacture for their own. For example an Satellite Kit is sold in 600 USD bus the cost for electronics are 150 USB and 10 USD to manufacture the cubesat structure in 3d printing, then even if your cost of shipping is 100 USD you have room to play for other expenses and revenue 440 USD. Well, you have to achieve a High level of knowledge at business and engineering for that vision and planing. That is one of the most important thing people never say on these talks, because they want it make to look easy and cool, remember successful companies are made by 1% top people in the world, that is why is not that simple and easy.

I call BS on certain points here. 3D printing is a great personal technology for anyone who takes the time to acquire a few basic design skills, or who has those skills already. Also, I don't believe this guy designed, printed, and assembled a robot arm with servos & electronics in 1.5 days because he was bored on a weekend. That's the kind of embellished story people tell after the fact to impress venture capitalists and demoralize potential competitors. There's no Iron Man in real life. He should have said 3 or 4 days just to make it believable, but in reality it was probably a week or more.
The idea and thinking about it did take longer- but the first, basic design itself could have taken a weekend for a simple project. A few of my own projects are things I've been sitting with for days, weeks, or even months, but the actual pencil to paper and paper to screen time is counted in hours or days. Assembly- yeah, depending on the printer and models... printing itself probably takes the majority of time.

I watched all slant 3D channel videos and was hard to find this gem 💎 from the same inventor/creator/genius Gabe
I'm just getting into 3d printing molds for silicone casting medical task trainers, Slant 3D has been such a help with the amount of information they share. It's awesome to see Gabe's passion for helping continue to this day.
'The creation of physical things at the speed of thought' Now that is mind blowing! I'm going to remember that forever.
It continues to be a pleasure to work with Slant 3D to manufacture all of our robotics kits as we continue to grow. Great Talk Gabe.
Isn't this literally Gabe's company? This is like congratulating yourself.
As he said: A kid can just create a model over a weekend, post it on the internet and say "If you want it, buy it."....that´s just so true...Thank you, this was worth watching
My fridge handle is very happy for 3D printing :D. Old fridge, no parts available.
4 years later I finally realized all of this ...wish I got into it sooner. Same thing I always say with everything lol..

You can print metal too. And who know what else you could print if the technology is advanced.
these comments are lame this was a good ted talk

Can you please give link of your website?
You run a Etsy page?

Although 3D printing filament is more costly than moldable particles.

STL please :P
Can we do that kind of optimization for powder metallurgy ?
Interesting talk
Great talk! Super Cool! Thank you! 🤜🏼👍🏼
Should have made a hand made silicone mold for all the parts, and cast it.
Unless, of course, the 3D printed process was the draw for your pre orders.

You need to have your printer farm print up a printer farm
And they DO!
Thats exactly what prusa does
Shipping costs are still huge and eat up your sales.
No really you can partner with the shipping companies for huge discounts

Cheaper printers have more problems. At scale, every common malfunction is diagnosed properly and fixed.
And any production line has ISSUES that cause problems.

Hire a photographer...
Worst photo ever, verbal description would have been better...
Liking this video so far though
what about metals ?
It will be lighter (due to hollow inside), but with weak strength at z axis, comparing to CNC or molding.
What printer are you using in the farm?
I don't know the answer, but it seems to be custom build by his company

and now when printers can cost 200$ yeah ud be surprised lol
How is this even a TED Talk??
Lol nice try frank
Isnt that very logical?
Is this a TED talk?
Did he pay to talk over there?
