The Invisalign process Invisalign orthodontics uses a process that includes biocompatible polyurethane resin and uses 3D Systems' stereolithography (SLA) 3D printers. Invisalign products have been approved by the U.S. Food and Drug Administration since 1998.Clear Aligner molds are 3D printed via SLA. Can Invisalign braces be 3D printed? You can do that if you have access to the right equipment, as did college student Amos Dudley.
Using his university's 3D manufacturing and printing setup, which included a Stratasys Dimension 1200es, Dudley was able to create a custom alignment tray similar to Invisalign, which he named Orthoprint. However, it wasn't an easy task, as Dudley first had to research orthodontics, figure out how Invisalign works in the first place, and learn how the plastic used in the manufacturing process can help shape teeth. Because Dudley wanted to correct his crooked teeth, he had to develop an animation of the 3D model that featured a series of frames showing his teeth moving in the correct positions. Invisalign is a series of invisible aligners made of a thermoplastic material that look like teeth whitening trays.
Since Invisalign aligners are transparent, they are practically invisible and few will notice that you are wearing them. There, digital models for aligners are created based on 3D scans performed on patients and sent back to the United States. My 3D printer can't compete with the quality I get from the Invisalign lab, and there is currently no software available to private doctors that allows them to prepare aligners to move teeth to the desired position. With so many benefits of invisible aligners, it's no wonder people wonder if 3D printers can produce their own Invisalign alignment trays.
As technology advances and becomes more refined, some have even set out to do what seems impossible, such as printing invisalign braces to correct crooked teeth. Your dentist takes casts and scans your teeth to create a series of custom-made Invisalign aligners that can move your teeth in sequence until they are straight. While 3D printing may seem like a recent manufacturing trend, Align Technology, the makers of Invisalign, pioneered 3D printing technology in the healthcare industry several decades ago, when it created a process that uses 3D printing to make clear aligners. My teacher said that transparent braces like Invisalign are an example, but I can't find information about this online.
By producing 220,000 clear aligners per day, Align Technologies, manufacturer of the Invisalign brand, pioneered the use of 3D Systems' stereolithography (SLA) for this process.
