摘要:

针对产品熔融沉积制造过程的碳排放量化问题,按碳排放的来源将其分为物料碳排放、能耗碳排放和废料回收处理碳排放。通过分析整个制造过程中原材料制备阶段、熔融沉积工艺阶段、去支撑阶段、精加工阶段和废料回收处理阶段的能耗特点以及工艺特征,确定了产品熔融沉积制造过程的碳排放边界并建立了其量化模型,结合熔融沉积产品的加工特征和加工设备功率特性提出了熔融沉积工艺阶段的能耗碳排放量化方法。通过试验对所提出方法的可行性进行了验证,试验结果表明,能耗碳排放对产品熔融沉积制造过程的碳排放影响最大,物料碳排放和回收处理碳排放受打印原材料的影响较大。冗余的填充率会产生额外的物料碳排放与能耗碳排放。

Abstract:

Aiming at calculating the carbon emissions in fused deposition manufacturing (FDM), the carbon emissions are divided into the materials consumption carbon emission, the power consumption carbon emission and the waste recycling carbon emission according to the causes of the emissions. The carbon emission boundary of FDM and the quantitative model are proposed by analyzing its energy consumption and the features of five processes: the raw material preparation process, the FDM process, the support material removing process, the machining process and the waste recycling process. A quantitative method of the carbon emissions in the FDM process is proposed according to its characteristic and the electric power consumption. An experiment of the FDM carbon emissions calculation case is performed to validate the feasibility of the proposed method. The results show that the main source of carbon emissions in the FDM process are caused by power consumption, carbon emissions caused by materials consumption and waste recycling are mainly influenced by the raw materials for 3D printing, and the extra filling rate causes the extra materials consumption carbon emission and the power consumption carbon emission.

Key words: 3D printing, carbon emission, power consumption, fused deposition manufacturing
