快速成形技術是綜合利用CAD技術、數控技術、激光加工技術和材料技術實現從零件設計到三維實體原型制造一體化的系統技術。它采用軟件離散一材料堆積的原理實現零件的成形。

Rapid prototyping technology is a system technology that comprehensively utilizes CAD technology, CNC technology, laser processing technology, and material technology to achieve integration from part design to 3D solid prototype manufacturing. It adopts the principle of software discretization and material stacking to achieve the forming of parts.

具體過程如下：利用高性能的CAD軟件設計出零件的三維曲面或實體模型；再根據工藝要求，按照一定的厚度在Z向(或其它方向)對生成的CAD模型進行切面分層，生成各個棱面的三維平面信息；然后對層面信息進行工藝處理，選擇加工參數，系統自動生成刀具移動軌跡和數控加工代碼；再對加工過程進行仿真，確認數控代碼的正確性；然后利用數控裝置精確控制激光束或其它工具的運動，在當前工作層(三維)上采用輪廓掃描，加工出適當的截面形狀；再鋪上一層新的成形材料，進行下一次的加工，直整個零件加工完畢。可以看出，快速成形技術是個由三維轉換成二維(軟件離散化)，再由二維到三維(材料堆積)的工作過程。

The specific process is as follows: using high-performance CAD software to design three-dimensional surfaces or solid models of parts; According to the process requirements, the generated CAD model is sliced and layered in the Z direction (or other directions) according to a certain thickness, generating three-dimensional plane information for each edge surface; Then, process the layer information, select machining parameters, and the system automatically generates the tool movement trajectory and CNC machining code; Simulate the machining process again to confirm the correctness of the CNC code; Then, using CNC devices to precisely control the movement of laser beams or other tools, contour scanning is used on the current working layer (3D) to process appropriate cross-sectional shapes; Lay another layer of new forming material and proceed with the next processing until the entire part is processed. It can be seen that rapid prototyping technology is a work process that transforms from three-dimensional to two-dimensional (software discretization), and then from two-dimensional to three-dimensional (material stacking).

快速原型法不僅可用于原始設計中快速生成零件的實物，也可用來快速復制實物(包括放大、縮小、修改和復制)。其工作原理是，用三維數字化儀采集三維實物信息，在計算機中還原生成實物的三維模型，必要時用三維CAD軟件進行修改和縮放，然后進行三維離散化并送到成型機生成實

The rapid prototyping method can not only be used to quickly generate physical parts in the original design, but also to quickly replicate physical objects (including zooming in, zooming out, modifying, and copying). The working principle is to collect three-dimensional physical information using a 3D digitizer, restore the generated three-dimensional model of the physical object in the computer, modify and scale it with 3D CAD software if necessary, then discretize it in three-dimensional and send it to the forming machine to generate the physical object
