Summary: William Masters is an engineer, inventor, designer, manufacturing entrepreneur and business advisor/mentor. He holds the first 3D printing patent.,[1] along with patents for other 3D printing technologies (piezo transducer, extrusion, lithography, surface tension, and pin array) and computer assisted manufacturing. He founded Perception Kayaks,[2] at one time the largest kayak manufacturer in the U.S.,[3][4] and has served as a small business delegate to the Reagan and Clinton administrations.[5]<br><br>Masters is widely recognized as a pioneer in kayak manufacturing[6] and for his success in connecting whitewater enthusiasts with his kayaks.[7][8] The Wall Street Journal, in the August 15, 1998 edition of its Southeastern Journal, described Masters as "an intense, hands-on tinkerer who isn't shy about touting his accomplishments."[9] His innovations in kayak manufacturing, including rotational molding and working in engineered plastics instead of fiberglass, revolutionized the sport and recreational kayak markets.[7]<br>In the mid 1970s, Masters began work on a revolutionary manufacturing process, one which he compared to using a straw to deposit "spit wads." "When you shoot a lot of wads," he explained, "they begin to take shape. If you can control the direction of the wads and the motion of the device shooting them, you can produce any desired shape."[10]<br><br>Masters filed a patent for his Computer Automated Manufacturing Process and System on July 2, 1984 (US 4665492)).[11] This filing is on record at the USPTO as the first 3D printing patent in history; it was the first of three patents belonging to Masters that laid the foundation for the 3D printing systems used today.[12][13]<br><br>Masters introduced his 3D printing technology at CAD/CAM conferences in the late 1980s[12] with little success. Undeterred, he founded Perception Systems to handle research and development of his technology. In 1992, Perception Systems changed its name to Ballistic Particle Manufacturing (BPM)[14] and received funding from Palmetto Seed Capital, a state funded South Carolina venture capital group by headed by former South Carolina Governor Carroll A. Campbell, Jr..[15]<br><br>BPM launched its Personal Modeler 2100 in 1996, a device that used a computer aided design (CAD) system to manufacture an object of any shape by "shooting droplets of plastic."[16] During this time, Masters was forced to part ways with BPM to focus on his growing kayak business.[4]<br><br>The company, responding to pressure from investors and competitors, shipped and installed sixteen Personal Modelers in beta to customers and distributors. After eight years of product development, the technology was still unreliable, and most of the companies who received the Personal Modelers shipped them back and turned their attention elsewhere.<br><br>Negative publicity resulting from the product introduction proved to be fatal, which had struggled to develop its market. BPM would go out of business in 1997,[15] but the corporate entity still exists.<br><br>Two other American inventors developed 3D printing technology that achieved commercial viability in additive manufacturing: Charles W. Hull, who invented stereo lithography (filed Aug 8, 1984), and S. Scott Crump, who patented fused deposition modeling (filed Oct 30, 1989). Both of these men filed their patent applications after Bill Masters (filed Jul 2, 1984), making him the true father of 3D printing.<br><br>Masters's original 3D printing patent expired in 2004.<br><br>Perception Kayaks<br>As a student at Clemson University, Masters received a broken kayak as payment for fixing a friend's car. He repaired the kayak and his workmanship attracted the attention of other kayakers, who quickly asked him to repair their kayaks.[17]<br><br>A whitewater enthusiast from the first time he went down the Chattooga River, Masters launched his business with $50 in capital.[6] Over the...
