Screwball

Well, they did just come out with a short BTC ETF. 😉

Yes, that is very cool, but not what we are talking about here. His work is about using the 3D printer AS the main manufacturing devise. In our conversation here that Red is asking about is an entirely different animal as we are only making simple parts, even though the 3D printer in this case, is, the primary source of manufactured part. The video is an example of where this technology has come over the last X amount of years, and the things it can make when the parts are too complex to be built in other ways (materials and the ability of different printers to use these different materials which has opened the door to these fancy type parts). In our "normal" manufacturing processes to make our lives better via cheaper more affordable products (look around your house - almost everything is 3D modeled) prototyping is one of the first stages of the design process and the small 3D printers have been a huge help in time to market for our products. And in this case, the weekend warrior who wants to make simple parts on a desktop printer is the audience.

That is strange because I don't know anyone who does that. Let's walk through this one more time. This is a simple part 3D modeled in Solidworks (since you used that as an example). This is what you do first, no matter what 3D solid modeling package you have access to. This part is then "exported" to the 3D printer using a .stl file which the printer can import and optimize. By optimize (for lack of a better word), it will create the layering used for the printing process. Think old dot matrix printer than can move up as well (z). It starts at a point (home) and moves right and left (better yet x and y) on a flat plane laying down small droplets of plastic (for lack of a better word) to build the first layer of the part. Once the first layer is put down, it indexes a few thousands upward, and prints another layer on the shape. This is how the shape (part) is built. The software will also do the stress analysis (if that's what you want to call it) for you. For example; let's say you wanted to create a small airplane. The body of the plane is fairly rigid, but the wings are not. The software may choose to add a support/gusset/column at the ends of the plane wing because their own weight (as small as it is) may cause the wing to bend slightly therefore messing up the finished part. Again, this should be left up to the 3D printing software, with exceptions of course. A stress analysis program should be run on the real part, and is a very common part of the entire design process. FEA (finite element analysis) is a great tool, but like 3D printers there are good ones and bad ones. And yes, after the model is sent to the printer and optimized by the software, the finished model that is printed might have quite a bit of extra weird looking stuff attached. This is why I explained above how you might have to sand, file, or massage the final part to get what you want. Some of the supports/gussets/etc can be broken off if you are careful. That is the most common way they do things the last time I was allowed anywhere near corporate America.

True, but you don't design to it. You 3D model a part for what will be needed if it goes far enough to be put in production. The 3D printer, using it's own software will do the layering and optimization of the part to be printed (the prototype). No different if it was a non prototype (non-production) part that you wanted for your lawn mower. You don't design to the layers even though it's all about X,Y,Z. It's starts at 0,0, lays a substance of some sort along the X,Y plane, then indexes upward (Z) by whatever the software tells it (thousands of an inch), and repeats. This builds the part. Their software will figure that out. This technology helped us manufactures learn if a design is viable in a shorter period of time. R&D money is hard to get so time is as usual - priority one. We bought one because time on the corporate machines were backlogged and hard on the projects budget. Learning how to do things right should start from the very get-go. Nobody said it would be easy. Prepare accordingly. But to be honest, after watching corporate America over the last 40 years, I wondered many times how the hell they made or developed anything.

Designing shapes to fit 3D printing is a bad approach. You design a part for form, fit, and function. ASME y14.5-19XX (year) would be a good place to start if they are teaching that stuff.

I just saw this thread. I used a 3D printer but it was about 4-5 years ago, so things are probably much different now. We bought one for making prototype parts. I was working for an appliance manufacturer. We bought it off Amazon for about 2 grand. It was a little larger than a toaster, so the size of the parts were limited. It had different spools of plastic line in different colors. The line looked similar to line for a weed whacker and came on spools. You can make fairly complicated parts, but many times they would have to be sanded, filed, etc. to get the desired finished product, depending on the function. That may have gotten better now that the technology is better. But let's back up a little. Whatever you want to make needs to start with a 3D model. That's the toughest part IMO. To create a 3D model you need some sort of 3D software. That wasn't a problem for us as we had a high end 3D CAD software available at all times - this was our primary design software as it was. Once you have a 3D model, it is exported as a .stl file to the 3D printer. An .stl file stands for stereolithography type file. Some may also use a SLA file. This file gives the printer information so it can start at some point and lay down layers of plastic. Once you send the file to the 3D printer, the software optimizes the exported model for the printer. Our printer came with this software. Depending on the shape, sometimes the software would add supports, gussets, or whatever to help it create the final shape. This is also why you may need to final finish the part. It is not hard to learn the process IMO, and trail and error will also help. I don't know what is available today, and I'm sure they have gotten better for the price. Depending on what you want to make, the 3D software might be key IMO. There are all kinds of free and highly available 3D modeling packages, but they are not all the same. Some are very cumbersome and hard to learn. What is available for free I have no idea, but any commercial CAD package is better than the free stuff IMO, but you can't just go buy one of those - well you could if you wanted to spend the money - but not practical unless you are using it all the time. My advice would be to look 3D modeling packages over and find one that you like, and will make the kinds of models you want. Or, if you know someone with access to commercial 3D software, they could make you a model and export the .stl file. One place you might look is a local school or college that teaches CAD. They could maybe make you a model and export the file. The 3D modeling is the hard part IMO. Once created and exported, the printer and software will take care of the rest. Hope this help, and if you have any questions, feel free to ask.

I live probably 40 miles from the Davis Besse nuke plant in Port Clinton ,Ohio. To the east somewhere, but I'm not sure where anymore, there is a company that deals with beryllium. There have been many reports and even a book about what some call "cancer clusters' in residents of a local town (Clyde, Ohio) have experienced. There are rumors (maybe facts I don't remember) that there is a couple of deep underground waste dumps for either spent nuclear and/or beryllium, which some think has something to do with these problems. I don't know and they never seem to come to a solid conclusion. My point, any form of energy source comes with a downside in one form or another. As we have read from all the damage done by fracking, and it's impact of our land and water, especially when not done properly, or neglect. We better have a bunch of Erin Brockovich's.

I'm all for alternative sources of energy, but it's not as easy and quick as some seem to want us to believe. How much minerals (lithium, cobalt, etc) are needed for all the batteries (lots) and how do we get them (mining). How do we dispose of/recycle them once used, and how much energy will that take? What about the grid required for significant EV usage to charge at home, or on our roadways, and what is the cost and timeline to fund, plan, and create the infrastructure to do so? The grid should also integrate with wind, solar, nuclear, and whatever other energy sources we have now. It's all about EROEI (energy returned on energy invested). You don't mine 500 tons of lithium without energy, and lots of it, and 500 tons is nothing compared to what is needed, and it's not cheap. We have oil derricks all over the county, but they don't pump. Too expensive to come empty the tanks and haul away the oil. EROEI is not worth it. For investors, the key (IMO) is watching the transformational plan from what we have now to what we end up with in the future, to see what companies/sectors are going to see the funding to move forward. In other words, there will no doubt companies who benefit from the transformation and could be a very profitable trade/investment. The question will be who and when. I have not followed the push for green energy space but I would start with finding what the plan actually is. Is there such a plan that spells out the step by step transition to green energy and what methods will be utilized and what infrastructure will be required to do so? Maybe there is, I have no idea, but I would start there looking to find something that my be of value to an investor, and the timing it will require. My 2 cents.

Let me know when they have battery powered excavators too.

Not the Onion *** While I'm here. The other problem with the house across the street is it's not worth that much to begin with. Cheap credit and easy money does this. Not like we haven't watched this movie before. This is Cornhole, where things are cheap compared to the median and this is overpriced. *** It will be fun to watch the tape tomorrow for the FOMC release. Will be be 50 or 75 bps? If they go 50 I expect a strong move to the upside as I think the market has priced in at least 50, for now.

Who are the cash people? I'm guessing people like Blackstone (private equity) and/or foreigners. Blackstone is now 'the largest owner of real estate in the world That is from 2015.

This reminds me of something else. I was remodeling my basement last year. In October of 2020 I was buying 4x8x1/2 un-sanded plywood for a little less than $30 bucks a sheet. This is up from low $20 range the last time I bought. 2x4s were going for almost $5 when they used to be less than 4. By January, the plywood was over $50 bucks and the 2x4s were over $6, so I stopped. Screw that. Around the same time, I went to my son's house who lives in a sub-division around Columbus, Ohio. Just in the last year (at that time) they started at least 8 or 10 new homes. How the hell does a home builder square the skyrocketing price of lumber with a house he quoted for X amount? And what does the person who wanted the house built do when the builder comes knocking - saying I need more money - which is the only thing I can think of he can do. Of course product inflation is not exclusive to homes. I've been retired for a few years now, but I wonder how much machine tooling has risen.

So are all the people who have recently bought. They are underwater already. A house across the street from me sold a couple months ago for 144,000. The people who bought it put a for sale sign in the yard a few weeks ago with an asking price of 155,000. They are screwed. It won't sell, and if it did, they won't even get the 144,000. The machine is already broken.

I've had conversations with several of them and I wasn't impressed with any. I know the guy who replaced the guy I was talking about above. He took the classes, passed his tests, got the license and took over for this guy. He was previously an IT guy. I used to work with him. He probably didn't know what an option was before that. He didn't last a year. Another funny story about them. In 2009 I was sitting at my desk during the market hours (and the crash). I had CNBC on the TV, my laptop and extra screen were running my trading software. I get a knock at the door. It's none other than a guy in a green jacket carrying a small briefcase. I can see the Edward Jones patch on his jacket. This should be fun, so we talked a little bit at the door, then I invited him in. As soon as he saw my laptop, extra screen, and TV, he said, well I guess I'm done here, and scurried out the door. I laughed. So I sent an e-mail to a financial advisor buddy of mine who runs his own business. I told him I just had a EJ guy bang on my door and I never knew they made house calls. He asked me if he had a vacuum cleaner too. I got a big kick out of that.

I have to share this little funny I had today. I went to a local tavern and ran into a guy I haven’t talked to for maybe 10 years. He started out as a commodity trader for a local farm co-op. He went on to pass the tests required to be the head weenie of a local branch of Edward Jones. He is now living elsewhere, retired, and is here for a week. Probably 8-10 people around the bar. The conversation was about the market, and how much money they were all losing. So of course they are asking him what they should do. Of course he has no answer, other than saying he only has stocks in some Hawaii something, and something else that didn’t make much sense. Which is nothing more than financial advisor speak bullshit they learned to pass the test that helps teach them to say said bullshit. He then went on to say something to the effect of – I don’t know what to tell you – other than I’m glad I’m not still doing it. Of course. So the guy sitting right beside him said something like “WTF? You are the one who put me in all this stuff – and all you have is I don’t know what to tell you?” That pretty much ended the conversation. Passing the Series 6 is enough to allow some arrogant dick to fuck up a lot of people’s money, the rest just fits into the systematic looting of the average person. It is not hard to pass, can be done in a short period of time, and the more tests you pass the more damage you can do. Way too easy when trusted with a bunch of people’s money. Fiduciary duty they call it. I call it a scam. But it was fun watching him sweat. And besides, he chose the job, and if he didn’t think shit like this wouldn’t happen – then he is a dumb ass. So now we have established he is not a good fiduciary, but also a dumb ass. To be fair, I’m not sure if anyone can be a good fiduciary in today’s world. As Carlin might say – the game is rigged.

A quick Google search will get you this; We don't have those numbers, but the same pickle. Great work geniuses.

In 1973, as a junior in high school, during the oil embargo when we had to ration gasoline (which was a complete zoo, and a bunch of pissed off people), I was armed with one of these puppies along with a wad of bills in my shirt pocket. Good luck with that today. I've thought about setting up a stand out in a public place with a cash register change drawer, a laptop, and timer. Here, make 20 bucks if you can give the right change back in 10 seconds once the random number hits the screen. Of course take a video of people trying to do this. I think it would be great comedy.

A personal finance class would be good for anyone at any age, adjusted for the level they need addressed. Like compounding. Look how much you will gain by saving your money as it compounds over time. Oh, wait. Saving's interest rates are what???? Bad example. Credit interest rates and inflation rates say "hold my beer."
