Four-dimensional-printed deformable honeycombs can produce pro-programmed shape deformation and different properties under external stimuli, and the manufacturing process parameters are the dominant factors affecting the microstructure and properties of the manufactured honeycomb structures. Although many researchers have investigated the effects of manufacturing process parameters on the mechanical properties of printed materials, there is still a lack of research on the relationship between manufacturing process parameters and properties of honeycomb structures. Therefore, a novel honeycomb structures which has two configurations under temperature stimuli is proposed, and the optimum manufacturing processes for the printing of this honeycomb are selected considering the compression and energy absorption properties simultaneously. The novel honeycomb is designed and printed with fused deposition modeling technology, which have hexagonal configuration (Structure I) and semi-triangular configuration (Structure II) under external temperature stimulus. The energy absorption capacity of Structure I and compressive properties of Structure II are investigated under different manufacturing process parameters. The experimental results indicate that the layer thickness has the most significant impact on the mechanical performance of deformable honeycombs. The combination of a layer thickness of 0.2 mm, printing speed of 40 mm s−1, and 100% infill density are the best process parameters for the novel deformable honeycomb structures.

3D printing technology is the new frontier in building construction. It is especially useful for making small structures within a short period. Full construction, including interior partitions and exterior façades, can be achieved with this technology. This paper proposes a parametric Voronoi tessellations model for quickly generating and fabricating 3D-printed hexagonal honeycomb partitions for interior design. Comprehensive experimental testing was conducted to characterize the mechanical properties and investigate the energy absorption characteristics of the proposed 3D-printed hexagonal honeycomb while comparing it to alternative hexagonal honeycomb structures. The tests included tensile testing (ASTM-D638) of the printed Polylactic Acid (PLA) material, especially with the almost total absence of conducted research that reported mechanical properties for 3D printed material with low infill percentages such as 10%. In addition, an in-plane quasi-static axial compression testing of the lightweight honeycomb structures was also conducted on the printed structure with the same low infill percentage. Compared to non-Voronoi honeycomb structures, the Voronoi honeycomb resulted in superior mechanical and energy absorption properties with energy absorption values ranging from 350 to 435 J and crash force efficiency being 1.42 to 1.65.

“…Often such structures are studied from the mechanical point of view, but in reality they act as good energy absorbers, also thanks to the shape return properties of the material chosen for the manufacture. It has been seen in some studies as the design of the cell and the process parameters, influence in an important way the maximum compression load and energy absorption [17], [18]. PLA is more powerful than other polymers commonly used in FDM technology [19].…”

Abstract. The behavior of solid cellular structures in polylactic acid (PLA) manufactured by Fused Deposition Modeling (FDM) is herein investigated. In particular, the manuscript investigates the capability of permanently deformed PLA structures to restore their starting shapes, once a thermal stimulus is applied on them. In this study, a structure called Rototetrachiral was produced, which originates from Rotochiral and Tetrachiral. The latter was tested to verify its mechanical response and its ability to absorb energy when subjected to a compression stress, repeated over several cycles. The experimental results showed a close connection between the structure’s ability to absorb energy and its extent of damage, which gradually increases with the number of cycles. Microscopic analysis shows that the central cells are the most deformed. However, the applied thermal stimulus allows to recover the deformation, ensuring good performance of the structure for a certain number of cycles.
