熔融沉积成型彩色打印技术研究

针对FDM的梯度渐变色打印,提出了一种对梯度渐变效果进行预测和评价的方法。利用Visual C++提供的MFC应用程序开发平台编写软件模拟两种颜色的梯度渐变,通过在软件上改变色彩细分量得到梯度渐变效果不同的图像,实现了对梯度渐变效果的预测。为了实现彩色打印,设计了一种彩色打印机。首先进行梯度渐变色打印实验,用软件分析在与模拟对应的色彩细分量下打印出的零件和模拟结果的梯度渐变效果,验证了模拟结果的正确性,实现了对梯度渐变效果的评价。然后进行多色打印实验,实现了彩色3D打印,为彩色3D打印技术的进一步发展提供了参考。

Research of Fused Deposition Modeling Colorful Printing Technology

Aiming at Fused Deposition Modeling (FDM) gradient color printing, a method to predict and evaluate gradient effects is proposed. Using the MFC application development platform provided by Visual C++ program software, two gradient colors were simulated. By changing the amount of color subdivision in the software to obtain the images of different gradient effects, the prediction of gradient effects was achieved. In order to achieve colorful printing, a colorful printer was designed. Firstly, the gradient color printing experiment was performed. The gradient effects of the parts printed under the color subdivision amount corresponding to the simulation and simulation results were analyzed by software. The correctness of the simulation results was verified and the gradient effects were evaluated . Then the multicolor printing experiment is carried out to realize the colorful 3D printing. Moreover, it provides reference for the further study of colorful 3D printing technology.
