Article Synopsis
- - Four-dimensional (4D) printing enhances traditional 3D printing by introducing movement in response to external stimuli, with potential uses in industries like robotics, aerospace, and automotive.
- - This study investigates a new method of 4D printing by integrating microcellular foaming processes with common materials like PLA, design patterns, and evaluating their dynamic behaviors.
- - Results show that 3D-printed specimens can achieve predictable deformations through gas saturation, indicating that conventional materials can be used for 4D printing, paving the way for innovative applications without needing specialized smart materials.

Article Synopsis
- Previous studies faced challenges in measuring changes in high-pressure vessels due to sensor issues and gas desorption errors in polymer-gas mixtures.
- A new device using magnetic sensors was developed to measure real-time gas-saturated polymer changes inside high-pressure vessels, specifically testing polymethyl methacrylate under varying temperatures and pressures.
- The study proposes a new model for deflection in high-pressure environments and demonstrates that this method allows for accurate, in-situ measurement of polymer behavior, aiding in better control of high-pressure polymer processes.
