Path Planning Method for Large-Area Stamp-Based DLP Printing

To address the issues of low efficiency and difficulty in interval printing splicing in large-area stamping-based stereolithography, a print path planning method based on an improved ant colony algorithm is proposed. The approach involves adjusting the distribution of ant parameters, updating the pheromone mechanism, and incorporating a time evaluation function to specifically solve the optimal print path problem. Experimental results show that this method achieves shorter print path lengths compared to the Zigzag algorithm and more effectively reduces the number of interval prints and the difficulty of splicing compared to the original ant colony algorithm, thereby improving print efficiency and quality.
