摘要：Filament bad material extrusion additive manufacturing (MEAM) is one
定语
四月英文of the most commonly ud techniques in additive manufacturing. In spite of recent notable development in the MEAM process, there is still a need to develop more materials that can be printed consistently using this technique. Isotactic polypropylene (PP), a popular thermoplastic material, undergoes rapid crystallization and subquent volume contraction. This can lead to residual stress buildup in PP parts when procesd using MEAM, resulting in poor adhesion to the printing platform, poor geometric tolerance, and mechanical performance. In this work, the effects of varying composition of low molecular weight hydrocarbon resins added to PP are investigated. Specifically, the thermal behavior, crystallization, morphology, and printability of the blends
