目前積層製造技術中的熔融沉積成型(Fused Deposition Modeling，FDM)是廣為使用的三維立體列印機。此技術受到成型原理限制無法列印彩色物件，僅能夠於列印中替換材料達到變換顏色，並且可變換的顏色較少。因此本研究整合噴墨列印技術及FDM列印機達到列印件彩色物件。
本研究整合噴墨印表機及FDM列印機此兩種系統，以達成列印全彩物件。立體層的成型以FDM擠製白色內層實體及透明外層，此兩列印層產生一夾層間距，並以噴墨印表機噴塗UV墨水數次後將FDM擠製層填滿。其中噴墨層數需與FDM列印層厚配合，因此以重複噴塗UV墨水並量測固化後的疊層高度，可得知噴墨層數與FDM列印層厚的比例。而夾層的間距及外圍透明層厚度為影響色彩效果的主要因素，因此測試不同間距的夾層及透明層厚度，由結果可得知當夾層的間距及透明層厚度越小時有較佳的顯色效果。研究中探討熔融沉積成型技術整合噴墨列印技術的可行性及重要參數，並成功的以夾層填充之概念實現多色彩列印件，若未來改善FDM列印精度及噴墨印表機的控制方式，將可提升彩色列印件的品質。

Nowadays, Fused Deposition Modeling (FDM) Technology is most widely used in the three-dimensional (3D) printer. Due to the limitation of FDM, it cannot print full-color parts. Only limited colors can be achieved by changing filaments during printing. Therefore, research planned to integrate inkjet printing technology with FDM printer to print color parts.

The system developed in this research combined a FDM 3D printer and an inkjet printer capable of full-color printing. In each 3D printing layer, the FDM 3D printer extrudes the white inner portion and transparent outer layer with a gap in between, while the inkjet printer prints UV ink into the gap region several times to meet the same height of the extruded layer.

Additionally, the number of ink jet laminated times has to match with layer height of FDM, therefore, use repeatedly sprayed UV ink to measure the altitude of solidification laminated, the proportion between number of ink jet laminated times and layer height of FDM could be found. The points that affect the color effect which were the thickness of gap and outer transparent layer, therefore, the both thickness had been tested. The results show that the both thickness more thinner could have the better color effect.

In this research, the feasibility of color FDM printer and parameters of color printing had been study, inkjet printing technology has been successfully integrated into FDM which is used the idea of layer-covered to achieve colorful printing parts. In the near future, if the printing accuracy of FDM and the way of control inkjet printer could be improved, quality of color printing parts will greatly increase.
