HP launched its Multi Jet Fusion polymer 3D printers in 2016, and since then, it it has become one of the top sellers of polymer 3D printing (3DP) systems. The company claims that in 2018 alone, its customers printed more than 10 million parts. At RAPID + TCT 2019, HP announced that its customer SmileDirectClub plans to produce 20 million dental molds per year for indirect production of clear aligners. While indirect production of aligners in large volumes is not a new application (e.g., Invisalign), the company's approach where excess material and already-processed plastic mouth molds will be turned into pellets for injection molding is a promising example of using 3DP to create value from end-of-life products.
