Shane Wighton, from the YouTube channel Stuff Made Here, used 3D-printed tooling to form a sheet metal component as part of a concept validation process. Metal manufacturing is essential for all areas of the economy. Because of their strength, stiffness, and long-term durability, metal components are used in applications from appliances to construction parts and car body panels. Traditional metal manufacturing techniques include forming, casting, molding, joining, and machining. Sheet metal forming involves various processes where force is applied to a piece of sheet metal to plastically deform the material into the desired shape, modifying its geometry rather than removing any material. Sheet metals can be bent or stretched into a variety of complex shapes, permitting the creation of complex structures with great strength and a minimum amount of material. Sheet metal forming is the most cost-effective forming procedure today for manufacturing parts in large quantities. It can be highly automated in factories or, at the other end of the spectrum, manually operated in metal workshops for small series parts. It is a versatile, consistent, and high-quality procedure to create accurate metal parts with limited material waste. From metal cans to protective housing for hardware, parts created by sheet metal forming are found everywhere in our daily lives. In this article, learn the basics of sheet metals, the various sheet metal forming processes, and how to reduce the cost of sheet metal forming with rapid tooling and 3D printed dies.

Strive (ASST) is set up to absolutely moon. The catapult has been loaded. ASST holders might have this question: What happens to common equity if Bitcoin rises and the balance sheet either stays static or keeps accumulating through SATA issuance? Using CEBE math, I modeled two scenarios with Bitcoin going from roughly $68.5k to $126k. Scenario 1: Static balance sheet No new Bitcoin. No new SATA. No additional capital formation. Just the existing balance sheet riding Bitcoin higher. In that scenario, ASST goes from roughly $15.86 to $37.24. That is still a very strong outcome, because the company’s existing Bitcoin exposure appreciates and CEBE per share rises as fixed senior claims shrink in BTC terms. At $126k Bitcoin, CEBE reaches roughly 17,488 sats per share. $37.24 stock price with the multiple staying flat and zero new Bitcoin purchased :) Scenario 2: $200 million of SATA issued every month Same Bitcoin path. Same starting point. But Strive adds $200 million of SATA every month and uses it to acquire more Bitcoin. In this scenario, the stock goes from roughly $15.86 to $54.21. CEBE rises to roughly 25,456 sats per share. The Bitcoin stack grows from about 19,000 BTC to roughly 45,900 BTC. This is where the mechanism gets violent. The static balance sheet benefits from Bitcoin appreciation. The SATA issuance scenario benefits from Bitcoin appreciation plus monthly balance sheet expansion. That means the common equity is not simply waiting for Bitcoin to go up. It is watching the company potentially compound its Bitcoin exposure while the denominator gets partially protected by the capital structure. At the end of the model: Static case: $37.24 stock price SATA monthly case: $54.21 stock price Difference: +$16.97 per share Relative uplift: about 45.6% If SATA issuance is done at attractive terms and deployed into Bitcoin, the common wins big after Bitcoin moons. That is the whole game. This is amplified Bitcoin. And if the market starts pricing that correctly, the stock does not merely track Bitcoin. It can re-rate around the speed and quality of true Bitcoin-per-share growth:

A woman who spent nine years gluing paper models in a print shop just told a room of physicists their whole field stands on a mistake, one line, no hedging: "Every theory we have takes space and time for granted, like a bagel that forgot it was once a flat sheet of paper." That's Bianca Dittrich. She has a free lecture course that asks one question: what is left of geometry once you quantize it? The answer is: far less than you can picture. Quantum gravity looks like one more field theory. Buried inside is something stranger. Every quantum theory we have puts fields on a fixed stage, flat or curved, and does the physics on top of it. Here the stage itself is the thing being quantized. Your gut reads an atom of spacetime as a tiny grain sitting somewhere. Wrong. It cannot sit anywhere, because it is the somewhere. The move is invisible to human intuition, which is exactly why the people who get anywhere stop asking where the pieces are and start asking what a measurement even means. In 3D the whole thing collapses in a way that should scare you. No matter, no cosmological constant, and gravity is locally flat everywhere. Six degrees of freedom per point, all of them eaten by diffeomorphism symmetry. A field theory that ends up with finitely many real degrees of freedom, sometimes zero. None of it is hidden. Cut a parallelogram out of paper, glue the edges, and you have a torus. Flat everywhere, and yet two numbers survive that no local measurement can see. The lecture is free. Here is the trap: you feel every equation you can solve, every geometry you can draw, as progress. What you cannot feel is the gap you have to cross. Ten to the forty-one, from the Planck scale back up to the world you live in. And crossing it is the only thing that pays. Almost every approach still cannot show it recovers ordinary physics at the far end, and almost everyone quits long before then. The math is free to learn. The nerve to stop trusting your picture of space, that part you still have to bring yourself.
