CAD-CAM technology has allowed clinicians and laboratory technicians to change how treatments are planned and prostheses are fabricated [8], favoring and promoting the use of printed models. A dental model is a reproduction of the teeth and surrounding oral tissues obtained through an impression, either digital or analogically. The models are used for patient diagnosis, as well as for prostheses fabrication [9]. The accuracy with which the models reproduce the different oral situations will be decisive in the prosthesis fit in the mouth, influencing the passive fit of the structures [10]. Printed models are widely used in various branches of dentistry, such as prosthodontics, oral and maxillofacial surgery, implantology, orthodontics, endodontics, and periodontology [11]. Traditionally, these models have been fabricated in stone cast, which carries risks associated with the material, such as degradation, fracture potential, storage space, and loss of surface structure [12]. However, to date, most printed models are obtained by additive manufacturing. Additive manufacturing has unique advantages over traditional and subtractive methods. Among the benefits of 3D-printed models are the space-saving capabilities and the ability to manufacture customized parts with unique geometric characteristics [1, 13, 14, 15]. The disadvantages are that the supports must be removed, and the employed resins can irritate the oral mucosa by contact or cause damage by inhalation [16, 17]. Among the various AM techniques, DLP technology is becoming increasingly popular for producing dental parts [18, 19, 20]. The product is produced layer by layer directly from 3D data by exposing consecutive layers of photoactivated liquid monomers to ultraviolet light and curing according to the required final product shape. This type of technology uses a digital micromirror device (DMD) that projects the image of the 3D object to be manufactured onto the surface of the resin, so depending on the geometry of the part to be printed, these DMDs change their orientation [21, 22]. Multiple factors must be considered that affect the accuracy of 3D models. Primarily, the quality of the file from which the model is printed must be taken into account; the fidelity of the printed model begins with the quality of the digitization of the patient's dental data. If there are inaccuracies in the digital scan, these can be reflected throughout the printing process, leading to errors in the final product. Additionally, the technician's expertise in performing the 3D printing is significant, as they are responsible for preparing the model in specific design software and selecting and controlling the printing parameters and the conditions under which printing occurs. The ability to choose the appropriate settings and adjust the printing parameters based on experience and knowledge of the material and machine is crucial for the success of the print. Regarding the 3D printer, the type of technology used, its resolution, as well as the printing parameters, such as layer thickness and print orientation, are crucial to obtaining more accurate models. As for the printing material, it is essential to select a dimensionally stable material with the appropriate mechanical properties since shrinkage during polymerization and degradation over time can affect the final quality of the printed object. Other factors to consider are those related to the post-curing process, where the material's final strength and dimensional stability are achieved. Insufficient curing can leave the material soft and deformable, while excess can lead to brittleness. Finally, cleaning processes to remove unpolymerized material and finishing methods to remove supports can influence the dental model's final texture and dimensional accuracy.
