Therefore, effectively managing and reducing the impact of these wastes on the environment is a pressing issue in the low-cost rapid prototyping process.

To address this issue, many companies and research institutions are exploring effective waste management methods. Recycling and reuse are two common approaches. Recycling involves processing waste materials for reuse in the prototyping process, such as screening and cleaning discarded powder materials for reuse in 3D printing. Reuse, on the other hand, involves disassembling and categorizing waste materials, with recyclable materials being reused in other areas, such as recycling discarded plastic parts for manufacturing other plastic products. These approaches not only reduce waste generation but also lower operating costs for enterprises, maximizing resource utilization.

However, waste management is not without its challenges. Enterprises need to consider how to handle large amounts of waste, ensure the safety and environmental friendliness of the disposal process, and reduce processing costs. Therefore, it's essential for companies to develop scientifically sound waste management plans, choose appropriate disposal methods based on actual conditions, ensure proper waste handling, and minimize negative impacts on the environment and enterprises.

In summary, waste management is an indispensable aspect of the low-cost rapid prototyping process. Enterprises need to prioritize waste generation and management issues, actively explore effective waste management methods, and achieve maximum resource utilization and environmental sustainability.
