Creación rápida de prototipos

With the aid of computer-aided design or solid reverse method to obtain the prototype or part geometry and structure, and use this to build a digital model, and then use the computer-controlled mechanical and electrical integrated manufacturing system, the material is "three-dimensionally stacked" formed point by point and side by side. After necessary processing, it can meet the design requirements in terms of appearance, strength and performance, and achieve a rapid and accurate method of manufacturing prototypes or actual parts. Depending on the complexity of the part, this process typically takes 1 to 7 days.

Various rapid prototyping technologies entering the application field use different molding mechanisms, but their processing and manufacturing processes are similar, including the following three steps:

1. Producir modelos de diseño CAD. Primero, se utilizó un paquete de software de diseño asistido por computadora (CAD) para generar un modelo sólido tridimensional de la pieza. El software de modelado de sólidos comúnmente utilizado actualmente incluye: Pro / E, UG-Ⅱ, Power Shape, etc. También es posible obtener la información de descripción tridimensional de la pieza mediante ingeniería inversa.

2. Convierta el modelo de diseño CAD 3D al formato STL (STL es el estándar de la industria de tecnología RP). En el proceso de conversión, factores como la precisión del procesamiento, la carga de trabajo del procesamiento y la capacidad del archivo deben considerarse de manera integral.

3. Use the pre-processing software to convert the STL model into a processing file, that is, cut the STL model into 0.01 ~ 0.7mm thin layers according to different manufacturing processes. In this process, the coordinates and processing direction of the workpiece to be processed should be selected according to the performance requirements and the principle of minimizing the processing time, while taking into account the support during the processing of the workpiece.
