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.
