How Does 3D Printing Work?


The 3D Printing Process

3D printing, also known as additive manufacturing, creates three-dimensional objects layer by layer from digital data. According to Xometry, the process begins with capturing detailed scans and images of the patient's teeth and jaws using an intraoral scanner. These scans are converted into 3D CAD (computer-aided design) files containing all dimensional information.


The 3D printer then builds the dental appliance or model by laying down successive thin layers of a specialized printing material, such as biocompatible resins or metal powders. As described by Dentsply Sirona, each layer corresponds to a thinly sliced horizontal cross-section from the 3D CAD file. The layers fuse or harden to form a solid object matching the patient's unique dental anatomy.


Dental 3D Printing Technologies

Different 3D printing technologies like selective laser sintering (SLS), stereolithography (SLA), material jetting and fused deposition modeling (FDM) are utilized in dentistry. The Institute of Digital Dentistry notes that these techniques enable direct 3D printing of custom dental appliances such as orthodontic aligners, crowns, implant models and surgical guides from digital patient data.
