Visualized Simulation Based On 3D Printing Processes

3D printing, so-called additive manufacturing refers to successive layers of material are formed under computer control. Fused deposition modeling is a kind of 3D printing technology, which works on an "additive" principle by laying down material in layers. The plastic filament or metal wire is unwound from a coil and supplies material to produce a model. Therefore, the models with overhangs need support structure.As to verify the reliability of the algorithm and ideas when studying support structure, the mainstream method is optimizing the details of procedure after actual printing. But it is time-wasting to print a model every time with the limitations of fused deposition modeling. Furthermore, such tests often fail because of the unstability of algorithm. Such a method not only increases the cost, but also reduces the efficiency of verification.In this paper, we present a visualized simulation method based on 3d printing processes to verify the printed model with support structure. It is a novel verification method, which aims to take the advantage of computing capabilities of computer, gain the reality of the printed result efficiently in purpose to increase the efficiency. Firstly, we introduce how to imitate the 3D printer based on fused deposition modeling; then analyze the data storage type and select the line segment as the storage object; after that, we choose mass-spring model as simulation model. By utilizing the L-BFGS of the optimization algorithm, we obtain the status of layer after printed. The experimental results show that our method is feasibility.
