Ice floating on water is a great manifestation of negative thermal expansion (NTE) in nature. The limited examples of natural materials possessing NTE have stimulated research on engineered structures. Previous studies on NTE structures were mostly focused on theoretical design with limited experimental demonstration in two-dimensional planar geometries. In this work, aided with multimaterial projection microstereolithography, we experimentally fabricate lightweight multimaterial lattices that exhibit significant negative thermal expansion in three directions and over a temperature range of 170 degrees. Such NTE is induced by the structural interaction of material components with distinct thermal expansion coefficients. The NTE can be tuned over a large range by varying the thermal expansion coefficient difference between constituent beams and geometrical arrangements. Our experimental results match qualitatively with a simple scaling law and quantitatively with computational models.

“…115 Further, this method can be applied to functionalization of the PEG hydrogel with arginine-glycine-aspartic acid ligands for specific localization of cells. 116 These studies have shown the possibility of 117 Fluorescently labeled polymer microparticles such as fluorescein isothiocyanate (FITC)-or Cy5-labeled latex particles were spatially patterned in the scaffold layers. Fibronectin-derived peptides and heparin sulfate have also been successfully conjugated in the scaffold material.…”

“…The materials used in SLA are mainly based on PPF, trimethylene carbonate, or gelatin . With continuous exploration and development, researchers are increasing the types of photocurable polymers and attempting to apply multiple materials (Arcaute et al, 2010). In addition, encapsulation of cells during the process has proved feasible (Chan et al, 2010;Lin et al, 2013).…”

Bone defects arising from a variety of reasons cannot be treated effectively without bone tissue reconstruction. Autografts and allografts have been used in clinical application for some time, but they have disadvantages. With the inherent drawback in the precision and reproducibility of conventional scaffold fabrication techniques, the results of bone surgery may not be ideal. This is despite the introduction of bone tissue engineering which provides a powerful approach for bone repair. Rapid prototyping technologies have emerged as an alternative and have been widely used in bone tissue engineering, enhancing bone tissue regeneration in terms of mechanical strength, pore geometry, and bioactive factors, and overcoming some of the disadvantages of conventional technologies. This review focuses on the basic principles and characteristics of various fabrication technologies, such as stereolithography, selective laser sintering, and fused deposition modeling, and reviews the application of rapid prototyping techniques to scaffolds for bone tissue engineering. In the near future, the use of scaffolds for bone tissue engineering prepared by rapid prototyping technology might be an effective therapeutic strategy for bone defects.
