Abstract

Low-temperature additive manufacturing of magnesium (Mg) alloy implants is considered a promising technique for biomedical applications due to Mg's inherent biocompatibility and 3D printing's capability for patient-specific design. This study explores the influence of powder volume content, size, and morphology on the mechanical properties and viscosity of polylactic acid (PLA) matrix composite filaments containing in-house-produced magnesium-calcium (Mg-Ca) particles, with a focus on their application towards low-temperature additive manufacturing. We investigated the effects of varying the Mg-Ca particle content in a PLA matrix, revealing a direct correlation between volume content and bending strength. Particle size analysis demonstrated that smaller particles (D50: 57 μm) achieved a bending strength of 63.7 MPa, whereas larger particles (D50: 105 μm) exhibited 49.6 MPa at 20 vol.%. Morphologically, the filament containing spherical particles at 20 vol.% showed a bending strength that was 11.5 MPa higher than that of the filament with irregular particles. These findings highlight the critical role of particle content, size, and shape in determining the mechanical and rheological properties of Mg-Ca/PLA composite filaments for use in material extrusion additive manufacturing.

摘要

由于镁（Mg）固有的生物相容性以及3D打印可实现个性化设计的能力，镁合金植入物的低温增材制造被认为是一种很有前景的生物医学应用技术。本研究探讨了粉末体积含量、尺寸和形态对含有自制镁钙（Mg-Ca）颗粒的聚乳酸（PLA）基复合长丝的机械性能和粘度的影响，重点关注其在低温增材制造中的应用。我们研究了在PLA基体中改变Mg-Ca颗粒含量的影响，发现体积含量与弯曲强度之间存在直接关联。粒度分析表明，较小颗粒（D50：57μm）的弯曲强度达到63.7MPa，而较大颗粒（D50：105μm）在20体积%时的弯曲强度为49.6MPa。从形态上看，含有20体积%球形颗粒的长丝的弯曲强度比含有不规则颗粒的长丝高11.5MPa。这些发现突出了颗粒含量、尺寸和形状在决定用于材料挤出增材制造的Mg-Ca/PLA复合长丝的机械和流变性能方面的关键作用。
