What problems will prototype rapid prototyping technology face?

3D rapid prototyping prototype

What problems are faced by rapid prototyping technology, most of which come from the development level of the technology itself, among them, the outstanding performance is as follows:

PROCESS problem

The Foundation of rapid prototyping is the layered superposition principle, however, it is of great research value to use what material for layered superposition and how to do layered superposition. Therefore, in addition to the above common layered overlay forming method, some new layered overlay forming methods are being studied and developed in order to further improve the performance of the parts and improve the forming accuracy and forming efficiency.

material problem

research on molding materials has always been a hot issue, the performance of rapid prototyping materials should be satisfied: ① it is conducive to the rapid and accurate processing and molding; (2) the materials used for the direct manufacture of functional parts in the rapid prototyping system should be close to the requirements of the parts for strength, stiffness, moisture resistance and thermal stability; (3) it is conducive to the subsequent processing of Rapid mold making. The development of new RP materials, especially composite materials, such as nano-materials, heterogeneous materials, materials that are difficult to produce by other methods, is still the direction of efforts.

accuracy problem

at present, the accuracy of rapid forming parts is generally at ±0. The level and height of 1 mm (Z)The accuracy of the direction is even more so. The basic principle of rapid prototyping technology determines that the process is difficult to achieve the surface quality and accuracy indicators with traditional machining, and integrates the basic forming ideas of rapid prototyping with traditional machining methods, complementary advantages is one of the important methods to improve the precision of rapid prototyping [3].

software problem

currently, the hierarchical slicing algorithm used in the rapid prototyping system is based on STL file format, which is to use a series of triangular grids to approximate the data files of the CAD model, and this data representation method has many defects, for example, there will be some gaps in the triangular grid, resulting in data loss, and the step effect caused by plane layering, which also reduces the surface quality and forming accuracy of parts. At present, we should focus on developing new model slicing methods, such as feature-based model direct slicing method and surface layering method, that is, do not convert STL format files and directly slice CAD models, the profile of each section of the model is obtained, or the layer-by-layer slice data obtained by reverse engineering is used to directly drive the rapid prototyping system, thus reducing the error generated by the triangular surface approximation and improving the forming accuracy and speed.

Advantages of the extension 3D prototype:

1. The 3d printing prototype model imported by Israel is relatively high in accuracy, the printed prototype model has little deviation from the actual one.

2. Have 6 years of experience in the field of 3d printing and are technically more mature.

3. The confidential software is installed on the computer. Any computer that has not been authorized cannot open the 3d drawings copied by the extension, and the secrecy is strong.

4. Enter into a confidential agreement with the customer to make information confidential have legal effect.

5. Compared with CNC machining, it is significantly characterized by fast printing speed.
