MIT researchers have developed a technique called liquid metal printing (LMP) that can rapidly produce large-scale parts using liquid metal. By depositing molten aluminum into a bed of tiny glass beads, the aluminum quickly hardens into a 3D structure. LMP is at least 10 times faster than comparable metal additive manufacturing processes, making it suitable for applications in architecture, construction, and industrial design where high resolutions are not necessary. The researchers demonstrated the technique by printing aluminum frames and parts for tables and chairs, showcasing the potential for creating functional furniture. However, the process still faces technical challenges in achieving better control over the flow of molten material.
