近年來，隨著3D列印機相關專利的解除，諸多自動化零組件商紛紛投入這個市場，但價錢普遍昂貴。其主要運作原理為掃描物件後，經由影像處理，產生步進馬達路徑，馬達驅動器再隨著路徑驅動可三軸活動的高溫噴頭擠出塑料建構而成。基於以上模式，我嘗試著使用低廉成本來購買DIY組件，相互搭配以達到3D列印機的效果。本論文是以王建富學長所著基於Raspberry Pi 之2D 移動繪圖筆平台為本，處理器方面依然選用RPi，此平臺較為友善且便宜，而主要更動處在於硬體平臺，選用原平臺一半的成本建構，但可達到相同功能得機械物件，並且大為優化原平臺的強度與擴張性，使原架構無法達到得功能，可於此平臺實現。

In recent years, with the lifting of the 3D printer related patents, many components manufacturers have invested in this market, but the price is generally expensive. The main operating principle is to scan the object, through the image processing, resulting in stepper motor path, motor drive and then with the path-driven high-temperature nozzle can be extruded plastic construction. Based on the above model, I try to use the low cost to buy DIY components, with each other to achieve the effect of 3D printer. This paper is based on the Raspberry Pi's 2D mobile drawing pen platform based on Wang Jianfu, the processor still use RPi, this platform is more friendly and cheaper, but the main change is in the hardware platform, the original platform using half the cost of construction, but Can achieve the same function in mechanical objects, and greatly optimize the strength and expansion of the original platform, so that the original structure can not achieve the function can be achieved on this platform.
