3D列印普遍應用於智慧工廠，以自動化生產方式，客製化批次鑄造新產品，達成提升產品良率與設備稼動率，從而降低資金與時間成本。3D印表機具有速度快捷、價格低廉、操作簡易等優點。目前一般平價機種普遍採用「熔融堆疊層積成型」技術，然囿於使用線材特性，故偶會面臨諸如出料斷續等列印問題，以致列印模型出現質量不佳情況，更甚者列印過程發生中途斷線，均無形造成材料成本的耗損。市場上雖已有推出「斷料檢測」功能機種或額外附加配備，提供使用者在材料即將耗盡或突發斷料時啟動警報裝置，並自動暫停原先列印任務；或是僅有安裝「遠端監視」功能，搭載NFC材料識別技術，透過攝影機遠端監看列印進度與及時狀況。然而這些裝置均為獨立設計，僅能單一解決斷料檢測問題，或是遠端即時監看，而且採購具備此功能之機款售價均偏高於一般平價3D印表機，因此如何能以最少的裝置投資成本達到最大的列印效益，並如何將3D印表機納入智慧工廠自動化管理，實為3D列印的重要課題。本研究提出一套可在無線網路環境運作之3D印表機異常訊息即時通訊系統，並將硬體設備相關感測訊息加入至系統內，可以透過電腦端與手機端同步隨時監控，除了社群軟體Line推播即時通訊功能，如斷料警示、列印過程遠端監看之外，另提供在群組中對設備進行操控的能力，已達開或關「夜燈」及「印表機電源」。經實驗驗證，本研究對於3D印表機之斷料偵測異常通報及遠端即時監控裝置可以達到設計的功能需要，可用性強，預判可提供3D列印使用者智慧化操作效能。

3D printing is commonly used in smart factories, where new products are cast in customized batches with automated production methods to improve product yield and equipment utilization, thereby reducing capital and time costs. The 3D printer has the advantages of fast speed, low price and easy operation. At present, the general low-cost models generally use the "melted stacking and stacking molding" technology. However, due to the characteristics of the wire material, they may occasionally face printing problems such as intermittent output, resulting in poor quality of the printed model, and even worse. In the printing process, the disconnection occurred in the middle, which invisibly caused the loss of material cost. Although there have been models with the "material cut detection" function or additional equipment on the market, users can activate the alarm device when the material is about to run out or suddenly cut the material, and automatically suspend the original printing task; or only install " "Remote monitoring" function, equipped with NFC material recognition technology, remotely monitor the printing progress and timely status through the camera. However, these devices are all independently designed, and they can only solve the problem of material break detection or remote real-time monitoring. Moreover, the purchase price of models with this function is higher than that of ordinary affordable 3D printers. The minimum device investment cost to achieve the maximum printing benefit, and how to incorporate the 3D printer into the smart factory automation management is actually an important issue for 3D printing. This research proposes a 3D printer anomaly information instant messaging system that can operate in a wireless network environment, and adds hardware device-related sensing information to the system, which can be monitored at any time through the computer and mobile phones, except for social group software Line pushes and broadcasts instant messaging functions, such as material outage warnings and remote monitoring of the printing process. It also provides the ability to control devices in the group. It has reached to turn on or off the power of light or printing machine. Experiments have verified that this research can meet the functional requirements of the design for the material interruption detection anomaly notification and the remote real-time monitoring device of the 3D printer, with strong usability, and predictability can provide 3D printing users with intelligent operation performance.
