Dental 3D printers are machines that produce dental parts, from crowns to aligners. They apply advanced additive manufacturing techniques to create 3D objects layer by layer from digital models. Using such materials as resins and ceramics, these printers enable dentists to produce custom solutions for individuals. They not only simplify dental practices but also improve patient outcomes. However, it is a headache to pick out the best from various dental 3D printers in the market. For dentists, labs, and technicians, investing in the best dental 3D printer can significantly improve productivity and patient outcomes. Despite varying price points, these investments offer substantial long-term benefits.
In this article, we will explore how 3D printing technology is applied in dentistry, what the best dental 3D printers are, and how you should choose from different dental 3D printers.
Part 1: Understanding Types of Dental 3D Printers
Before learning about dental 3D printers, you need to first understand the three 3D printing technology types. As the 3D printing technology becomes a game changer in many industries, three types of 3D printers are applied in dentistry. Specifically, they are stereolithography, digital light processing (DLP), and material jetting or PolyJet printers. Each has its own features and fits in different scenarios.
1. Stereolithography (SLA)
Stereolithography (SLA) is the most popular resin printing technology and one of the most accurate 3D printing forms. It uses a UV laser to create 3D objects by curing layers of liquid resin into solid form. SLA printers use various material types, including standard resins, high detail resins, castable resins, high temperature resins, etc.
Because SLA materials are brittle, they are usually used for prototypes that undertake light loading. But also because SLA printing is accurate, it is widely used to make dental 3D printers, especially those for dental restorations, dentures, surgical guides, orthodontic appliances, and models.
2. Digital Light Processing (DLP)
Digital Light Processing, also known as DLP, is another 3D printing technique used for dental 3D printers. Unlike SLA printers, DLP uses a projector to cure layers of photosensitive resin into 3D objects. This technology is suitable for printing dental parts as it can produce highly detailed and precise parts with smooth surfaces.
Compared to SLA, it works faster because it applies light to form the whole layer at once rather than line by line. Although DLP is also popular among dental 3D printer producers, one disadvantage with DLP is that the single projection source can distort the image and lead to uneven build quality. The dilemma between speed and quality still remains unsolved.
3. Material Jetting or PolyJet Technology
Material jetting (MJ), or PolyJet printing applies inkjet technology to produce 3D printed products, including dental prosthetics. This technique works similarly as traditional ink printers. It deposits liquid photopolymer layers onto a platform and then cures it with UV light to bond the layers together.
Despite the advance in 3D technology, not all dental 3D printers can meet all your criteria. There are always some unfulfilled needs, be it speed, accuracy, or quality. But do not worry, as we will introduce you to some of the best dental 3D printers in the next part.
