Abstract Fused filament fabrication (FFF) is one of the most commonly used 3D printing technologies and has gradually become an important plastic processing technology. However, due to the variety of performance and application scenarios of FFF products, there is no research to comprehensively evaluate the environmental impact of the process. The environmental impact assessment method of FFF products under different performance requirements was proposed innovatively. Through the assessment, we found that the life cycle environmental impact of FFF products produced under various performance requirements can be up to several times different from each other and the FFF process can best reflect its environmentally friendly characteristics when manufacturing products do not require high strength and high surface quality. This paper aims to propose the rational application scenario and the positive solutions to reduce environmental impact for FFF, meanwhile provide future directions for the sustainable development of the FFF technology.

Introduction With rapid growth of the world economy, environmental problems are becoming increasingly serious. The manufacturing industry has a great impact on the environment, and the plastics processing industry accounts for a large proportion of the manufacturing industry. Since the synthesis of celluloid in 1869, the plastics processing industry, which has a history of nearly 150 years, has entered a new phase of transition in order to reduce emissions [1, 2]. The proportion of fused filament fabrication (FFF) technology in the plastics processing industry has increased rapidly, through which the plastics processing industry hopes to become more low-carbon and environmentally friendly to realize sustainable development. The FFF has replaced or assisted the practical application of traditional processes in single-piece and low-volume processing in the plastics industry [3, 4]. It is necessary for us to accurately assess and quantify the environmental impact of the FFF, which will help the plastics processing enterprises to use FFF technology sci
