研究目的
Investigating the development and application of an energy model for selective laser melting (SLM) machine tools to predict energy consumption accurately.
研究成果
The paper concludes that the developed energy model and simulation tool are effective for evaluating the energy demand of SLM. However, the study highlights the need for further optimization and validation to improve accuracy and reliability. The case study demonstrates significant energy consumption in SLM, suggesting areas for future research to enhance energy efficiency.
研究不足
