We all know that in the traditional dental mold making process, it will cost a lot of manpower from obtaining the impression to making the dental mold with plaster pouring, and a lot of dust, waste and noise pollution will be generated in the whole manufacturing process. At the same time, the accuracy of the dental mold can not be guaranteed. Therefore, more and more technicians are beginning to seek digital methods and cleaner application Quiet and efficient production tools to replace the traditional dental mold making process.
In the process of dental digital application, CNC digital processing mode, that is, material reduction manufacturing mode, was first accepted by everyone. At present, CNC has been widely used in the production of digital dental molds, especially in crown and veneer restoration. The zirconia material is cut by computer control, and the accurate crown and veneer are obtained. CNC manufacturing can support small batch production, but through long-term use, we found that the process of small batch production through CNC is relatively slow, and will cause a lot of material waste, which virtually increases the cost of denture processing. At the same time, small batch production requires frequent maintenance and replacement of accessories, such as drill bits, belts, etc. Therefore, small batch manufacturing through 3D printing has also become the first choice for many digital technicians. Of course, 3D printing can not only carry out small batch production, but also provide a new fast and convenient manufacturing way for the development of new businesses such as implant guide plate and orthodontics.
According to the survey, using the full digital manufacturing process of intraoral Scanner + 3D printing, almost no adjustment can be made in the process of intraoral tooth wearing by front-end dentists, and the return rate of dental crowns produced by technicians has been reduced from 5% to 1%. Now more and more technicians have replaced manual operation through more convenient, effective and convenient equipment production mode. The wide application and advanced level of equipment also determine the production level of technicians to a certain extent.
At present, oral digitization has become an inevitable development trend of the global oral industry, and 3D printing, as an indispensable part, has been paid more and more attention by oral practitioners, and the penetration rate is increasing year by year.
Why LCD dental 3D printer?
At present, three technologies SLA, DLP and LCD are mainly used in dental 3D printing applications. These three technologies have different characteristics:
Among the above three 3D printing and molding technologies, LCD and DLP are the most widely used in dentistry. A series of products can be made from orthodontics to repair, from guide plate to casting. Among them, DLP technology can achieve higher accuracy comparable to SLA technology when the forming size is small, but after enlarging the forming size, the accuracy will be reduced or the cost will rise sharply. Because of its unique technology, LCD technology can meet the needs of high precision and large size at the same time, and has an absolute advantage in small batch production.
In terms of imaging technology and hardware, the core component of DLP technology is DLP chip, which is a high-precision component and has been monopolized for a long time, and its image distortion correction algorithm is only in the hands of a few manufacturers, so the equipment cost is relatively high. The core component of LCD technology is general LCD screen, which has relatively low cost, less image distortion and good consistency. With the general commercialization of 2K, 4K or even 8K resolution LCD screens, under the same accuracy, the forming area of LCD equipment can be 2.8 times that of DLP equipment, and the cost is less than 50%. Therefore, LCD 3D printing products are more suitable for the digital small batch production and manufacturing of technicians and outpatients.
Why choose pionext DJ89?
At present, there are many low-cost LCD 3D printing devices on the market, which can be used to print animation models, but are they suitable for making digital dental products? Our answer is - not suitable. This kind of low-cost equipment is usually assembled with general LCD components, combined with cheap screw rods and light sources. Although it can image, the accuracy can not be guaranteed, let alone stable production.
Based on the current market situation and the professional dental market, let's introduce DJ89, a special dental LCD 3D printing product of PioNext brand, from several aspects.
Forming size
The molding size of dental 3D printer dj89 is 192x120x100mm. Such a large size can be tiled and printed. 13 1 / 4 dental molds and 4-5 half mouth models can be printed at one time. However, the printing time of a version only takes 1.5 hours, and the average production time of a model is only 15 minutes, which greatly improves the work efficiency.
Forming accuracy
As we all know, the forming accuracy of 3D printing equipment mainly depends on the hardware level, light source quality and material stability. In terms of structure, the key parts of 3dtalk ds200 use the products of international hardware manufacturers with high standards in the market, such as ball screw and guide rail. At the same time, high-strength hard alumina parts are also used in structural design. Therefore, it is impeccable in terms of product quality and structural stability.
High precision printing with self developed integral light source
Pionext adopts a new generation of self-developed optical system and realizes accurate control of light through the optical principle of reflection + refraction. What is an integral light source? It is composed of multiple micro light sources (6-12-30 lamp beads), and each micro light source is composed of four light-emitting chips. The energy uniformity of the light source can reach more than 80%, which greatly improves the gloss and fineness of the model.
Slicing software is simple and easy to use
Pionext DJ89 is unique in the application of slicing software. Equipped with self-developed slicing software, the interface is simple, the operation is simple, and the parameters are customized. Novices can also get started easily.
