Beginning in the early 2000s, dental 3D printing emerged as an experimental technology with limited applications. The initial focus was primarily on creating simple study models and basic surgical guides with relatively low precision requirements.
By the mid-2010s, technological improvements in both hardware and materials led to the adoption of 3D printing for more complex dental applications. Various printing technologies including stereolithography (SLA), digital light processing (DLP), and material jetting began competing in the dental market, each offering distinct advantages in terms of accuracy, speed, and material properties.
Material jetting technology, in particular, has gained significant attention in recent years due to its ability to produce high-precision dental models and guides with multi-material capabilities. This technology deposits photopolymer materials in ultra-thin layers and cures them with UV light, allowing for exceptional detail reproduction critical for dental applications.
The current technological trajectory is focused on addressing three critical aspects of material-jetted dental products: accuracy, sterilization capabilities, and dimensional stability. Accuracy is paramount in dental applications where precision at the micron level can determine the success of treatments such as implant placement or orthodontic interventions.
