A year or so ago I was looking into commercial grade 3d printers, trying to get my workplace to invest in one. Apparently it is very common for the large automakers (in North America at least) to not carry little/no spare parts for their assembly lines. They instead have a high end FDM 3d printer as well as a metal 3d printer. When a part breaks, they simultaneously start printing a replacement in plastic, one in metal, as well as order the proper replacement part. Depending on the part, the plastic one is complete in under a day and the line resumes operation. The metal one will take 2-3 days, and once it is complete it is installed and the plastic one is discarded. Finally, once the proper replacement arrives, it will be installed, and the metal 3d print is often kept as a quick stand-in for future breakdowns. 3d printing allows them to not have to keep large amounts of money tied up in spare parts for every possible breakdown, but still reduces the impact of any breakdown. If it's useful for large scale manufacturing, I think it's more than a useless toy.

[@willyjimmy8881]

We use 3d printers in our maintenance shops but can't sit around waiting for parts to print, downtime is way too expensive. We do prototype alot, especially experimenting with modifications for existing components. For some in-house developed equipment we print components where we can so we don't have to pay for custom parts from vendors. They're pretty invaluable at this point but most people never see them in use.

[@SaltMineRanch]

Hey Michael, thanks for everything you do. Mentioning that some things can only be created with additive manufacturing is great but but I feel that you've overlooked some of the most valuable applications related to this. Unless clients have previous experience with AM like aerospace users, I find that many people and organizations still need substantial convincing that "3D printing" is even something to be taken seriously and some seem to think it's new or a fad, remaining ignorant of the half a century of tremendous work and research that got us to where we are today. Hopefully the examples I provide can help shed light on the reality. I'm not sure how AM got this reputation of being a hobby thing, but there is a **lot** more to it. Starting at the simplest level, yourself and many of your viewers probably have products in your homes right now produced on factory equipment and continuous production processes I've upgraded with my 3D printed parts. Amazon boxes and packaging for food for example... Lots of the people reading this will likely have one of these things sitting in arm's reach right now. One of the ways we protect employees and improve flow is by using air transfer tables to hover thousands of pounds of material so you can move it with a finger instead of wrecking your back or using a ton of electricity. My air transfer nozzles make this possible at vastly reduced cost, enabling the small factories who produce these boxes to afford such upgrades and compete with the big outfits for contracts. Also, I build automation control systems such as touch screen equipped microcomputers to run these giant machines. Since I build everything from the PCBs and operating systems up to the final product, nobody makes mounting hardware, screen bezels, suitable electronics cases, etc. Rather than pay $50,000+ for tooling to injection mold something (useless, since they're all different) I can simply spend a handful of hours to design the parts needed, print them, test, and integrate them for end use in the factory. Mounts for other hardware, safety shields, cable guards, routing for air tubing and many other things benefit from this as well. I've spent over 6 years improving the production process on my own equipment to be able to reliably produce end use products which does come with a cost, but now I can make fancy things on inexpensive machines similar to an Ender 3 that big fab houses claim are unprintable and HPee and Strat-ahem printers simply *can't* produce due to the limitations of these systems. I've actually never printed a toy for anyone but my cats but I've produced automotive parts which were unobtainable like you mentioned, many tools for fabrication, medical and robotics components, and weapon safety improvements to name a few. Having worked in medicine for over a decade as well, I'd like to point out that 3D printed PEEK orthopedic implants are *the* ideal solution which can be customized for the individual patient, capable of achieving a flexural modulus similar to bone and better wear and rejection characteristics than titanium alloys. In some cases like pediatric cranial plates, 3D printing is the only practical solution. Models for surgeons to practice with before a procedure can be produced from actual CT/MR images of the patient in advance and used to reduce risk and improve outcomes, and to better inform the patient as well as biomedical equipment manufacturers assisting the team. The US Army now deploys with 3D printers to assist various missions, and replacement parts for Air Force aircraft can be produced on the spot without risking more lives, equipment, and money to send them to the site. Printed components allow me to design RADAR systems which have uniquely controllable beam paths, and the equipment I provide laser cutting and marking services with is largely printed in-house. Additive structures built by similar machines economically produce disaster shelters, homes, and agricultural structures in place to make basic survival more affordable, less harmful, and more energy efficient but that isn't exclusively using polymers. Given the complexity, serious nature, and how little most AM processes really have in common with printing, I really have a problem with the term "3D printing" in general. This isn't printing, you don't click "print" and magic comes out, it is nowhere near as trivial as that and "printing" seems to imply creating a visual representation of something. While this *can* be a use case for additive, that's like calling a freight train a cat litter carrier but I'm sure that is all my cats think they're good for. Engineers are just too busy solving problems or too constrained by the business and governmental requirements for secrecy to make videos about it, but I wish KZbin would quit perpetuating the concept that "printing" is simply for D&D, airsoft, and cosplay - this is absolutely untrue. I hope that content creators like yourself will cover some of these practical use cases in more depth in the future, and the fun and importance of becoming additive manufacturing technologists rather than consumers and printer collectors. Sadly, sponsored content may be paradoxically throwing fuel on the fire. I appreciate your policy on sponsored content, but I think it can create a conflict of interest for some. To earn money by working in manufacturing restricts your ability to make content about making, but becoming sponsored may imply that some creators should not talk about the important reasons why the all new XYZ printer mod is useless if you would just learn about how the machine works. Guys, you don't *need* any of the crap they keep trying to sell you. They're quick solutions to problems you can easily solve yourself. Sure, some are well designed and it doesn't get *easier* than buying something. However, nobody can sell you a better machine than you can learn to design, they can only sell you what they're capable of mass producing at a profit and that often comes with hidden costs necessary to sustain their business models. If you really like the technology behind the making then remember the spirit of RepRap and the whole point of the contemporary movement was for people to learn to build and improve the industry and the world, not to buy things designed by the community which are being sold as if they were developed by the silly brand names they sometimes represent. An "Ender 3" or a "Prusa i3" is basically just a kit for building a RepRap Mendel without having to source parts, have friends who are already CNC nerds, or learn a hundred things to get started. They're a starting point on a journey, not the destination so look beyond the retail solutions and think about how *you* can solve problems. If you made it through all that, thanks for reading lol.

I came up with a simple set of measurements and a drawing showing my very rough idea. I then found an engineer in Scotland (I'm in the USA) who hung out on the car forums where I hang out, and he and I polished up the design into something awesome (he did most of the CAD work, since I am a noob).

I like your content and watch you often. I had quite a bit of trouble breaking loose the fidget. Finally, clamped edge in vise and used 10mm wrench to break free. I also love designing and making these for myself and friends.

[@J_Madison]

For 95% of people, 3D printing is all about spending way too much money to make cheap trinkets you wouldn't bother buying in a store. For the remaining 5% or so who actually design custom stuff and print it.. well, my hats off to you.

[@TheOystei]

Thanks for including an update on the airbox, you said in that video that you would do a follow up on it after 6 months, but as far as i know that never materialized. But really good to know it's holding up. have been thinking about using the same filament to make some stuff for my own drift car as well.

[@DragRedSim]

Sim-racing is why I originally got into 3d printing. I’m still a relative newbie, but I’m getting towards printing at least functional parts. I have a couple plans in the works to that effect. For me, there’s nothing like seeing a need for something that doesn’t exist, designing it, having it brought into physical form, and using it successfully.

[@youruniquehandle2]

I work for a fortune 100 company and we use 3D printing all the time. We have a $50 million lab dedicated to additive manufacturing with dozens of printers including huge Stratasys FDM and metal printers. We have used these to make parts that are simply impossible with standard manufacturing techniques, to make tools & fixtures at a fraction of traditional costs, prototype ergonomics for same day iterative design... the list goes on and on. At this point anyone who thinks 3d printing is a gimmick is just ignorant.

[@PiefacePete46]

Jon: I reckon the target for the scoffers is the beginner/hobby 3D printer fraternity. We are our own worst enemies, as we often seem to show an endless stream of nonsensical objects, captured on video while en-route from the printer to the landfill! My satisfaction comes from practical solutions that I see and use every day. When the serial-criticisers see the sort of things you are creating, they have no choice but to skulk off into the undergrowth. I envy you your job; I went down a far less satisfying path!

[@QuiltersHandyman]

As usual great video, more hobbies such as two of mine, woodworking and ham radio, which have a wealth of 3d printed parts that are hard to find or expensive. I also would include cases for the hugely popular raspberry pi and other electronic parts and tools. I print many items for my wife...the quilting queen. In addition you don't have to be a designer as the 3D printing community freely share their designs and there are literally, as you well know since you are one of them, thousands of designers freely share their designs. Loved the toy maker...going to look into his work. You could make several videos on this topic.

[@onecarwood]

Great video and Liam is a great guy. He does a live stream every week and helps a lot of people that way too.

[@ziggybombers1563]

Seeing toys that help the unfortunate people almost brought a tear to my eye, thank you for sharing that. As a home woodworking man I use my daughter’s 3D printer, I’ve made a Dewalt router sled using printed parts and the run out is about 0.2mm over 900mm, there’s just no way I could get that accuracy trying to make it any other way. There is so much more I’ve done for my little workshop using 3D printing the list just goes on. Again great video bud 👍⭐️

[@mururoa7024]

I made a conformal fixture to hold my awkwardly shaped wifi router to the wall without the need to modify the router's body or damage it in any way. Because the fixture is conformal to the body of the router you almost can't notice it's there. I also regularly make odd shaped (woodworking) router jigs, adapters and tool organizers. I never make things that I can just buy.

[@PiefacePete46]

Ha Ha... I had nowhere to mount a WiFi extender, so I 3D printed a mounting bracket that allowed it to hang on the end of a bookcase without screws. Tidy solutions for one-off problems. :o)

[@HappyHarryHardon]

I’m brand new to 3D printing and am super excited that I’m able to make small car parts. Right now I’m printing a 3 circuit horn ring for a race car. It makes the buttons in the steering wheel work without external wires. It’s also removable. Thanks 3D printing!

[@peterplantec7911]

Michael, another excellent presentation. thank you.

[@anamewithnoface1330]

in my experience, People who hold the opinion that 3d printing is useless are people who have few practical skills. Somebody who solves their own problems is guaranteed to see the value in being able to design a solution to a problem and have the machine make it for you to spec. If you repair your own vehicle, have a household problem, build your own furniture, have a garden... If you have a problem, its very likely that with a little ingenuity you could design and 3d print a solution. People that don't think so often have no ingenuity, or cant see that potential.

[@DobbsyLondon]

I've had a neptune 2 for over 2 years now. I consider myself still a novice compared to most, but I just want it to work, and I want it accurate.

[@sysghost]

Whenever I meet a non-believer, I simply show them my electric scooter that I just arrived in riding on. It's filled with 3D printed parts such as extra battery holders, Display protection cover, mudflaps, extra turn light extender (made of TPU), phone mount, extra hooks to hang grocery bags on, lock-wire holder

[@reverse_engineered]

We were starting plants for our garden this spring and we wanted seed block makers, but they were sold out everywhere with lead times going into next year. I found a few models on line that I used for inspiration, then designed my own that combined the best of all the models. It worked great and saved us a lot of time preparing our seedlings.

[@kellyjean4981]

Such an eye opening video. I’m doing research in hopes of buying my first 3d printer. This video made me want one that much more! What a beautiful thing to be able to create items that could be donated to classrooms or to those who are in need.

[@larrybud]

2:40 In plastic a home hobbyist could make each gear independently with a file, glue the to pieces to make a single gear. Then the outer ring in two halves, joining them together. Not saying it would be fast or easy, but certainly can be done.

[@JoeyCbr]

Just wanna say cheers for your tips and uploads, I was completely new only a month ago but I have finally got my head around tinkercad and getting better at knowing what should be supported for a better outcome.

[@DrEckig]

Printing toys, lamps or other cool stuff as gifts created so many happy moments in the past few months of making & tinkering. Truly an amazing hobby that gives tons of joy for every gram of filament.

[@rbrianlindahl5499]

I've designed an expanding collection of small & large items for use in my metal & wood shop. From a new dial for my antique Atlas lathe, to myriad small brackets, fittings, and tools.

[@PWN_Nation]

Replacement parts is a huge factor for our family. We have a dearth of parts especially for our 32ft long class A RV (caravan). The mfg went out of business years ago, so many of the interior and chassis parts that fail on us here in Arizona (typically plastic ones that no longer hold up to the dry air and high levels of UV) can now be recreated with our FDM printer. We get to combine the joys of 'right to repair' with the knowledge that we're keeping equipment from the landfill...a two'fer!

[@gv71able]

I printed a replacement stop for my hedge clippers after one dry rotted and broke. My calipers and tinkercad and custom part finished. I work for a mold maker for door seals in the auto industry and there is 3d printed full size car doors for testing the seal fit and prototype fixturing used to hand notch the extrusion for prototype molds before production molds and notching equipment is made.

[@AW_DIY_garage]

One of the first things that I designed was the plunger replacement for my wife's KitchenAid mixer cheese grater attachment. I agree with you that functional prints are fun when they go right. Just today I rapidly prototyped three adapters for cups for my laser engraver. I was able to try out three different designs in the span of one day.

[@pxlaidan]

Mate, I’m a Senior Design and Technologies teacher, I love hearing your story. I can’t even get my school to purchase the Denford Mill for the F1 in Schools program. We are about to purchase our 5th 3D printer though, I’ll have to see if we can consider printing the body and add weights for the weight constraints.

[@jethro2512]

Good video Michael and thanks for reinforcing the value of 3D printing. Looking forward to the CAD tutorial.

[@parkflyer68]

Thank you for taking the time to make such informative videos Michael, They are great for people like myself who like to be creative but not quite sure how to go about doing it!

[@Av-ks8uc]

I work in automotive embedded systems prototyping, and got myself an ender 3 last year. I also kinda first thought it was only to make trinkets, but it was an amazing excuse for me to learn CAD tools to add to my resume, as I'm just a student/intern/almost engineer so any resume filler is welcome. It indeed enhanced my other hobbies, building random stuff with microcontrollers: now, with a bit of CAD, and a few cents worth of filament, my projects look finished and professional, as I'm no longer doing "CAD" (cardboard aided design). My favorite thing to do with my printer is something I think you already tackled on the channel: solving a niche problem only I have. For instance, for my car, I hate these phone holders that clamp on your AC vents: it blocks the air, and gets loose; and I also hate the others that suction the windshield: any difference in temperature in the night makes it fail. So I measured a bit, and designed a phone holder that jams in my CD reader that I do not use, and it fits my phone securely with a couple of TPU insert that "clip in" the main part like legos. Same for my desk setup, I have 2 monitors that for the life of me I couldn't get to fit next to one another flush, and it was triggering my OCD. I designed a small piece that holds them a perfect 30°, and has a little rail on top to hold my camera. Right now, I am designing a replacement piece for my AC units that broke, and that the manufacturer (Mitsubishi) quotes an ungodly amount of money for a small plastic piece. It really gives you a different outlook on things, you look around your office looking for things to improve, to make better, and to hack. On a more "serious" note, it is as you mentioned an AMAZING prototyping tool. It allowed us engineers to reclaim the manufacturing process, allowing us to build prototypes in barely days compared to weeks. Also... It's an hobby in itself! I've spent more time and money upgrading and modifying my printer, learned about CNC systems, got myself an actual CNC/laser, and spent a lot of time learning/honing each machine to the point it can make my visions real

[@gerritvisser]

One of many items designed and printed: I needed a V-block and mount for my Nikon Shadowgraph. Original was unobtanium, a Mitutoyo version was >US$600 used. Fusion360, import Canvas, calibrate to a known dimension, iterate once on the base and done. Now I can hold round and small pieces for optical comparison or measurement.

[@davem3048]

One use I have for my printers is to replace control knobs on my vehicles and appliances. All the radio and environmental control knobs on my 1998 Silverado are 3D printed. All measured and created from the original cracked knobs. I have over 200 useful part designs from vacuum cleaner accessory brackets to vibration dampeners. 3D printing has been very useful and a lot of fun for me.

[@ChrisBrown-ux8jn]

What an absolutely excellent video. You have a real gift. And given that I think you Australian like me makes it all the better.

[@dleland71]

First off, any one of my 'friends' who belittles my 3D printer, I make them something like a coffee coaster or a wall decoration. :) As to my projects, I was rebuilding a quad ATV when I discovered a very small, but necessary part was missing from the carburetor. I fired up Tinkercad and designed a replacement in minutes when a replacement would of taken a week to receive. That is just one example out of dozens of projects. Love your video and look forward to your CAD classes.

[@DCA001TUBE]

Well done Mate, I'm sick and tired of people looking at my 3D printer and making stupid comments. I just recently printed end caps for an old stair banister rail, which was made in the 80's and the end caps can't be bought anymore, if you get your finger caught in the end of that banister as your coming down stairs, you don't have a finger anymore! I also printed housings for some high resolution underwater cameras we installed in our local aquarium (29 of them), because the profesionally made stainless steel housings (316L) couldn't handle the electrolysis in the tank but the PETG ones work fine! People have to start to understand how important 3D printing is, and how much fun and how rewarding it is to design and print something.

[@transatlant1c]

One of the most useful models I’ve printed was also one of the simplest - I needed a spacer for a tap as the previous one has disintegrated from age. If I had the skill and equipment I might’ve been able to make it out of metal or wood, but less than 5mins in CAD and only a few more printing and I had a replacement part. I use this example whenever people ask me ‘so what do you print’.

[@kenniffss]

The hinges on my plastic drill bit case broke a while ago, have had it held together with cable ties which was less than ideal. Last night I sketched up some hinges and fitted them at work today, quite satisfying.

[@JohnHavord]

Great video. Might have been useful, to also highlight, the numerous files made by the community, that are available free.

[@lgude]

Thanks. I had my bath redone and one of chromed floor drains immediately rusted badly. I found a 3D printer file online that I liked and rescaled it to fit. Perfect first time in black PLA. A year later it just fell apart when I went to clean the drain. Oh NO! But Oh YES - the file was still on my Ender 5’s SD card and I soon had another. Parts are becoming hard to get for all sorts of things and 3D printing will help - that and older skills/techniques like welding. Prototyping the engine adapter plate was a superb example of how 3D printing can reduce errors inexpensively.

[@BariumCobaltNitrog3n]

I agree. For me, a 3D printer is a tool maker, parts maker, bracket and adapter maker and I just finished printing all the parts but the tube and lenses of a 4" Maks-Cassegrain telescope.

[@ericblenner-hassett3945]

Around 3 minutes mark you are mostly correct. It is ' possible ' to make in standard injecting molding process the inner gears and while still held to a portion of the first mold, could include the sun and ring gears. It is extremely expensive for the shear segments to fit with such tolerances and would make a less than one dollar toy cost over one hundred, even in 10 thousand unit batches due to the complexity. I have looked into a few videos for LEGO manufacturing and even they will not do such due to the per part created price. The tolerances to print in place makes the time to completion per piece versus the cost to pump out thousands with extremely expensive molds and a complex, multiple injection process, makes printing such toys the best option for almost anyone.

[@gibsonav]

I volunteered to teach 3D printing at our local library after finding out they had one they hadn't even turned on for two years (the person who knew how to use it left). After teaching quite a few kids on Saturdays (5 Saturdays in a row on four separate occasions!) they started their own club. The first thing they decided to do was to volunteer to make 3D printed prostetics for children who were in war zones. We partnered with a goup working with the Ukraine and were able to supply almost a dozen forearm to hand (left AND right) in varying sizes for different ages, and they did it all themselves. Proud of them!

[@RoseKindred]

I have few design skills, I tried to use Blender but I am horrible. That being said even with limited skills I found my printer quite useful. Printing parts that cost me $0.75 and saved $12 each while being stronger than the original for example. I am currently working on parts to help me start a business.

[@Vipcioo]

It can take a long time to count. I started like everyone with simple handles, hinges, fasteners for something. Then I grew CAD with Fusion 360 and it started ... Wish list from the family, or my visions of what will be useful for the home. And this is a clock for a boyfriend, and this is a hanger for headphones or a purse closure in the kitchen, not to mention the toilet rolls hanger. And on the way there were many other little things for the workshop, a lot of my own trials and experiments. But the most important thing is that we are not all sitting in front of the TV watching a soap opera, we are still creative. And that creates the value of our lives. Dot. I admire positively crazy.

[@RCjunkie]

Thank you for your time of doing the vids!!!!!

[@etzmannschnappuleck1181]

Absolutely agree! The selfmade solutions are the most satisfying projects!

[@reverse_engineered]

I am making vent covers with electronically-controlled louvres for my home's HVAC system. There are some commercial ones, but they are expensive and don't come in the right size for my home. Laser cutting and 3D printing have allowed me to manufacture parts quickly and easily that would have required much more expensive tools and a lot more experience to manufacture using traditional machining techniques.

[@rjinhobart7748]

I use my E3 for printing mounts for various authentication devices - card readers, RFID scanners, barcode scanners - to mount on the sides of POS terminals. I also print rear mounts for customer-side LCD displays for POS stations that don't have these as an option. The E3 paid for itself in the first 12 station rfid mount run. I also print various items for use around my home - powerboard mounts are a constant need, new levers for my toaster, knobs for my gas torch. Endlessly useful. Never printed a Benchy though!

[@casper01]

I am always looking for something cool to print and thanks to your information about E-nable I have constant things to print. 😊

[@abigailnicholson5017]

I work restoring classic Jaguar cars, and my printer has paid for itself multiple times over by printing a dashboard air duct that is not a available. The original is a rigid brittle plastic which often breaks with age, and the company who bought the tooling when Jaguar stopped making them broke the mold, and then decided it was not cost effective to replace it. I modelled in cad and print in tpu for flexibility when installing the dash. When the parts were available they sold for around £60 each, with 5 on a car. 4 hours and around 50g of material per duct and much more forgiving when installing.

[@KeithOlson]

For the CAD tutorial videos, FreeCAD + the OpenSCAD Workbench would be *fantastic,* as they each have their own strengths and weaknesses, and the convenience of being able to paste in a chunk of code and instantly create a fully modelled part CANNOT be overstated.

[@geor664]

Ive used openscad professionally and is great. Freecad has multiple issues which have been discussed elsewhere on various you tube channels. I found the UX problematic (Inconsistent) I don't use it any more. I strongly recommend trying Blender with the 3D printer library addin. (both free). There are many you tube tutorials on this. One of the best is from Maker Tails. And Michael, thank you for this 3D print overview.

[@bjhaynes7502]

I made a case for my son's shaving brush, tooth brushes, batteries...all for when we go on vacation. It made my life easy. I still need one more tooth brush holder. Next will be shaver holders, things for my son's Occulus, and video game systems, as soon as I finish upgrading my printer. And I would love to learn CAD so I could customize his stuff.

[@manicdan481]

My brother got me a 3d printer and the first thing I used it for was to make a template to drill holes for cabinet handles. I didnt care what the dimensions were, I just needed them all to match. 5 minutes of cad using a free program and a 1 hour print, and I had a perfect template and saved me hours of trying to measure and drill.
