Invisalign treatment has been growing in popularity since its launch in 1999, and its reach has spread around the world. Its use of digital scanning, computer modelling and 3D printing enables it to produce customised teeth aligners that steadily move the teeth into place over the period prescribed to each patient.

SmileDirectClub, a company founded in 2014 by Alex Fenkell and Jordan Katzman, has provided over 1 Million users with Custom Clear Aligners with pricing as low as 3$/Day. The Company has now partnered with HP to produce 20 million 3D printed molds over the next 12 months, targeted at more than 50,000 molds a day. The company will be using 49 of HP’s Multi Jet Fusion 3D Printing technology to manufacture the molds 24/7 with 6,300 workforces at 391 locations, therefore giving a tough competition to Invisalign.
