ely sachs is the living embodiment of 3-d printing
How investment casting molds and inkjet print heads from integrated circuits, metal foundry inspire people to invent 3- Printing technology? For Professor Ely Sachs, this is the story of how he came up with adhesive spray metal printing, in the invention of the whole 3- D. printing in the process. We know everything about today. The adhesive spray, in which the metal layer is deposited and combined with the adhesive to print the complete part and then heat to melt the metal, is one of the two core technologies of the desktop metal, it\'s a Sachs company. Established in 2015. The company has completed a series of e-level financing in the past January, raising nearly $0. 44 billion in total. Major investors include Ford Motor and Koch Industries. For Saks, he\'s on the fast TCT 3-today- The printing conference in Detroit began at the Massachusetts Institute of Technology in the 1980 s. \"As a young teacher at MIT, I have entered the second or third year,\" Sachs said . \". ( Saks was a professor of mechanical engineering at the school and is still a professor today. ) \"I\'m working on process control for integrated circuits. This exposed him to the plane process of circuit production. \"You start with a silicon wafer and then create the pattern of the circuit by adding and subtracting materials in layers,\" explains Sachs . \". At about the same time, he saw 3-D printing. \"I happened to visit a company based in New Hampshire, a beta site for the 3D system SLA [ Stereo printing, 3 more- D printing technology,” Sachs said. \"It was an accidental moment-I think, I have to go into this stage. Sachs is a mechanical engineer of a mechanical engineer who likes to visit the factory very much, he said, \"I have been in the mechanical store for a long time, during that time, make things-it\'s my true love \"-visit two other plants that offer extra inspiration. One is a metal foundry, where he learned that investment casting is made of metal powder and adhesive. The other is ink. Not only did he see emerging printing technologies, he also learned about many of their upcoming product improvements. With all these bits and pieces in mind, Sachs is working. \"As part of the research, I have discretionary funding and I hired a student to talk to colleagues and we put together a bunch of ideas. Because it\'s scalable and I know there\'s at least the first application in the field of metal casting. Saks is sure his new technology is the winner. But he is swimming against the tide. \"I\'m constantly challenged when I try to sell or raise money,\" he said . \". \"At that time, the laser printer was ahead of the ink --jets. I heard, \"you bet wrong, the laser will win! ’ all the time. Still, I stuck with it because not only does it have a better scope in terms of rapid prototyping, that was the focus at the time, but it also has a better range in terms of actual manufacturing. From there, the story of Sachs with 3- Overall printing. \"After five years, I thought everything would be 3- 3d printing, \"he said. \"I was attracted by enthusiasm. \"He worked in it for about 12 years, left it for 8 or 10 years, and then finally came back forever. During this period, the business has changed. “3- \"D printing is very profitable in making prototypes,\" Sachs said . \". \"It will take a while for the focus to shift to production. ”It’s in full- Saks now thinks his optimistic performance in technology is rewarding. The production system of desktop metal combines adhesive injection with one-way inkjet printing, with a production speed of 100 times faster than the laser system and more than 4 times faster than the closest adhesive injection alternative product. \"The one-way through the line printer approach achieves a high productivity vision,\" explains Sachs . \". \"Our print head has up to 32,000 nozzles, so it\'s really massively parallel printing. Our goal is to spread the powder at a rate of one layer per second-we are close, but we have not arrived yet. \"The biggest advantage of binder spray printing is scalability. \"The limitation of laser power is that you can actually evaporate the metal,\" Sachs said . \". \"That\'s why you see multiple lasers being used. But there is a limit on how much you can zoom in. \"The challenge of developing any new manufacturing technology is to understand the interaction between machines and materials. This is suitable for Metal Powders and adhesives. Still, Sachs sees a bright future. \"Metal printing is very hot right now and my expectation is that it will explode-maybe even replace some polymer processes,\" he said . \". \"This is the biggest opportunity area in our industry. In terms of the environment, we have reason to support metal parts, not plastic parts-in the coming years we will see more and more people interested in withdrawing from plastic. But he believes new technologies will bring the greatest opportunities. \"The greatest potential-and most importantly-to make something that cannot be made now. Look at the manufacturing technology of the past-the threshold for entry is high, but the technology has been around for a long time. Investment casting was invented in India 4,000 years ago and has been processed for hundreds of years. \"A new kind of manufacturing is not always there. This is an opportunity to make products that we can\'t make with other technologies, reduce the cost of existing products and have a whole new way of manufacturing.
