Now in the field of dental applications, as the demand for 3D printing gradually increases, the requirements for 3D printing are also getting higher and higher. Facing the market challenges, EPLUS 3D worked together Voxeldance to overcome the difficulties. After months of testing and optimization, we developed a series of excellent 3D printing pre-processing software tools for dental application. The pre-processing time for 3D printing has been changed from 30 minutes to 6 minutes, which allows users to get rid of the tedious 3D printing pre-processing process, greatly improving printing efficiency and reducing labor costs.
Problems during 3D printing dental crowns data processing
1. Position of dental crown
When performing tooth restorations, the metal crowns manufactured by 3D printing need to be placed on the reduced natural crowns, which require the suitability of the manufactured crowns on the edges of the buccal and lingual sections, axial and occlusal gaps, the difference in different sections should be consistent, and to ensure accurate edge tightness. At the same time, the precision of the metal inner crown will directly affect the comfort of the porcelain tooth wearer. Therefore, it is necessary to place the crown with the occlusal side facing down during the pretreatment. If the occlusal side is placed up, the support will be built in the crown. The subsequent de-supporting and polishing process will increase the workload of car gold, and It will not be able to guarantee the accuracy of the buccal, lingual, and occlusal gaps, and loses the advantages compared with the traditional cast gold-ceramic crowns.
2. Productivity and Cost-Effective
The user sets the charging standard based on a single tooth. A larger number of crowns are placed on the platform, which can not only improve processing efficiency, but also help denture processing plants reduce production costs and improve overall efficiency.
3. Support generation for the crown
Usually, for laser powder bed laser melting process, the construction of the support structure is necessary for several reasons: one is the strengthening of the support structure and the stability of the support parts and the construction platform; the second is that the support structure takes away the excess parts during the construction process The third is that the support structure can prevent parts from warping and reduce the probability of failure during the construction of parts.
The requirements for support are as follows: 1. The support structure and the generated points are required to be suitable and strong enough to ensure that the printed crown does not deform; 2. The generated support is required to be easy to remove, reducing the work of car gold in post-processing Difficulty; Third, it requires efficient and accurate support generation, and no manual adjustment is required after running the support script to generate support; Fourth, the support structure is required to be small in size and reduce the powder consumption of support printing.
4. User-friendly and Efficiency
Generally, people who operate printers do not understand 3D printing process and technology very well, so they need application engineers and software teams to provide a complete solution. The solution requires the user to perform the operation steps as simple as possible and the processing time required for each step is short. The user only needs to perform simple operations according to the instructions of the plan, and can quickly complete all the 3D printing pre-processing procedures and successfully print.
