The idea of 3-D printing is exploding right now in almost every sector! Today, I am happy to introduce you, the listeners, to my son, Trent Esser. Trent and his friend are starting a 3-D printing company in St Louis, called Printerior. The company is currently in the beta testing phase, and they are getting ready to have their first product launch within the next two to four weeks. Trent is joining me on the show today to talk about his exciting new venture and explain how 3-D printing works.
