    3D From Nothing- Season 2 Episode 1- Tom talks to Velo3D salesman Paul Hollowaty

    Paul Hollowaty, at one point held to title of number 1 additive salesman in the World!  Now with Velo3D has a lot to say in this episode about the start of Velo3D and the the current business plan.   Paul talks about Benny Buller's original vision and how the contract manufacturing now works. The solution Velo3D has delivered to Lockheed Martin includes a Sapphire printer, Velo3D’s Flow print preparation software, its Assure quality assurance and control software, and its underlying Intelligent Fusion manufacturing process, which optimizes the additive manufacturing process by combining process simulation, geometry-based detection, and build process monitoring during print execution. This end-to-end solution gives customers the confidence that the mission-critical parts printed using Velo3D’s additive manufacturing technology preserve design intent. It also provides customers with the ability to produce identical parts across any Velo3D Sapphire printer, so as production needs increase, customers can merely add additional printers to their production facilities anywhere in the world or utilize Velo3D’s network of contract manufacturers. A recent article at 3Dnatives.com says "Velo3D points to advanced metal AM solutions, especially its own Sapphire® systems, as the solution to overcome these barriers. Industrial metal AM machines allow for more aerospace companies to turn confidently towards additive manufacturing. But how exactly will this be accomplished? Looking at each barrier individually, advanced metal systems have built-in solutions to overcome them, making metal 3D printing more reliable and easier for users. For example, a non-contact recoater arm in advanced AM systems eliminated issues with protruding surfaces, ensuring that there will be no recoater clashes. This in turn significantly reduces the likelihood of failed builds as well as provides for a smoother surface, allowing for less time in post-processing. When it comes to the question of software, advanced industrial metal systems work to integrate extreme process controls, resulting in better parts, printed faster, with metallurgical structural integrity. A robust workflow also ensures that not only is printing easy, as CAD files can be worked with directly and optimized within the machine, but processes are monitored, also reducing failures. Finally, the company points to superior gas ventilation present in these industrial solutions, allowing for the evacuation of accompanying soot and thus more rapid laser fusion... Velo3D concludes, “Advanced industrial metal AM technology has at last reached the point where it reliably delivers on the promise of unprecedented design freedom, shorter lead times, reduced development and production costs, and the highest-quality, fully-functional end-use parts for aerospace and defense.”

    Brandon Crain Interview-Texas Metal Printing, Printing New skin, new houses and Rockets

    This week Tom Gendich interviews Brandon Crain. Brandon Crain has more than 15 years of in-depth, technical, and hands-on experience in traditional subtractive manufacturing. He has worked his entire career as a team member of a growing and successful family run waterjet cutting and machining service company. Brandon has experience in all areas of a thriving small business, including shipping and receiving, purchasing, sales, quality management, and business management. Understanding and experiencing 15 years of busted knuckles, broken tools, and scrapped parts, he gained interest in the growing 3D metal printing / DMLS (Direct Metal Laser Sintering) industry. Recognizing the capability of additive manufacturing technologies and seeing opportunity to participate in the next industrial revolution, Brandon and his wife, Kristi, established Texas Metal Printing, LLC. This week we have:3D printing of new skin can help burn victims!ScienceDaily.com talks about “A new handheld 3D printer can deposit sheets of skin to cover large burn wounds -- and its "bio ink" can accelerate the healing process.The device, developed by a team of researchers from the University of Toronto Engineering and Sunnybrook Hospital, covers wounds with a uniform sheet of biomaterial, stripe by stripe.The bio ink dispensed by the roller is composed of mesenchymal stroma cells (MSCs) -- stem cells that differentiate into specialized cell types depending on their environment. In this case, the MSC material promotes skin regeneration and reduces scarring.” Would you buy a 3D printed house?“Take a Peek Inside the First of Its Kind to Hit the Real Estate MarketThe same technology used in small 3D printers can print a real house—and the first 3D home is already on the multi-list. Three-dimensional printing isn’t just for little things—SQ4D, pronounced “S-squared,” a New York construction company, uses patent-pending 3D technology, known as Autonomous Robotic Construction System (ARCS), to print houses on-site. Now, the company’s first full-size spec house is on the market, and it looks a lot like a traditional house. Check out their 3-bedroom, 2-bath house in Riverhead, New York, and keep reading to find out more about this new type of construction. Printing Rockets. 3Dprint.com says that “Indian space startup AgniKul Cosmos has developed and test-fired a fully 3D printed rocket engine. Produced as a single component in one run, the higher stage semi-cryogenic liquid propulsion engine called Agnilet was built to support its orbital-class launch vehicle Agnibaan. Even though several space agencies and companies are using additive manufacturing (AM) to churn out rocket parts and engines – most notably SpaceX, Relativity Space, and NASA –, AngiKul claims Agnilet is the first single-piece 3D printed rocket engine to pass a fire test successfully.Igniters, injectors, cooling channels, mounts, manifolds for fuel and oxygen, and nozzle are just a few of the hundreds of components that go into making a rocket engine. Moreover, most of these are incredibly complex geometries that traditionally require several conventional fabrication techniques and machining processes, such as welding, brazing, and drilling, to create a flight-worthy engine.
