[0105] Synthesis of Photocurable MDI-PEGMA

[0106] MDI-PEGMA was synthesized using 4,4'-methylene bis(phenylisocyanate) (MDI) (10.00 g, 40.00 mmol), which was added to a round bottom flask with inert atmosphere, stir bar and heated to 60°C. After the MDI reagent melted, poly(ethylene glycol) methacrylate (PEGMA) (32.55 mL, 100.00 mmol) was added dropwise, and reacted at 60° C. for 8 h. Afterwards, the reaction was allowed to proceed overnight at room temperature. The synthesized compound (MDI-PEGMA) was collected using a positive displacement pipette and analyzed by proton NMR spectroscopy ( 1 H NMR) and by Fourier transform infrared spectroscopy (FT-IR...

Abstract

The present invention relates in part to a photocurable resin composition comprising a first compound formed from the reaction of a diisocyanate and an isocyanate reactive compound comprising a double bond, a second compound comprising one or more double bonds susceptible to polymerization, and a photoinitiator. The invention also relates in part to a method of making the photocurable resin composition. The invention also relates in part to a method of fabricating an article comprising the steps of providing a photocurable resin composition comprising a first compound formed from the reaction of a diisocyanate and an isocyanate reactive compound comprising a double bond, a second compound comprising one or more double bonds susceptible to polymerization, and a photoinitiator; 3D printing the photocurable resin to form an article; and curing the article. The invention also relates in part to a 3D printed resin article.

Description

[0001] Citations to related applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 747,694, filed October 19, 2018, which is hereby incorporated by reference in its entirety. Background technique [0003] Dental malocclusion affects approximately 60% to 75% (or 4.6 to 5.7 billion) of the global population. Therefore, there is a huge global demand for orthodontic treatments to correct malocclusions. Approximately 15% of these cases are treated with orthodontic clear aligners (690 to 855 million patients per year), representing a $1.5 billion market size. From 2018-2021, the compound annual growth rate of this segment is expected to be 12.16%, and by 2021, it may reach 2.7 billion US dollars. The aligners are manufactured through the following process: 1) taking a dental impression of the patient using a 3D scanner; 2) digitizing and converting the dental impression into an STL file compatible with stereolithography CAD software; Orthodo...
