Exploring Thermal and Mechanical Strains During Laying Down Process in Fused Filament Fabrication
This study analyzes strain evolution and thermal behavior during FFF of PLA using strain gauges and infrared imaging. Microstrain levels depend on printing conditions, with adhesion‐induced compression during cooling and peak strains in early layers. Microtomography shows minimal porosity, while thermal imaging reveals rapid heat penetration, strong ...

Dynamic velocity planning method for parametric toolpath with mode-based tracking error control
Abstract This paper presents a dynamic velocity planning method for tracking error prediction and control based on a theoretical model of a servo control system. A balance between machining efficiency and machining accuracy is achieved by the proposed approach compared with the traditional method of reducing kinematic constraints and ...

Fabrication‐Directed Entanglement for Designing Chiral and Anisotropic Metamaterial Foams
This work introduces fabrication‐directed entanglement (FDE), combining viscous thread printing and topology optimization to program entangled foams with spatially patterned stiffness. By tuning coil density, FDE enables anisotropy, programmable Poisson's ratio, and chirality in foams.

Four-axis trochoidal toolpath planning for rough milling of aero-engine blisks
Abstract The Blade Integrated Disk (Blisk) is one of the key components in the aero-engine, it is generally manufactured by the multi-axis milling and almost 90% raw materials are removed. To avoid the full immersion of a cutter in the rough machining of a blisk channel, the trochoidal milling is a promising strategy since it can keep a small ...
