“…This is close to the yield strain of both the Polylactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS) plastics usually employed in 3D printing. 16 The maximum strain is only reached at the very edge of the flexure, hence we believe the plastic deforms in a reversible manner. This is borne out in practice as none of our microscope stages have yet failed due to flexures snapping, even after 6 months of use.…”

Open source hardware has the potential to revolutionise the way we build scientific instruments; with the advent of readily-available 3D printers, mechanical designs can now be shared, improved and replicated faster and more easily than ever before. However, printed parts are typically plastic and often perform poorly compared to traditionally machined mechanisms. We have overcome many of the limitations of 3D printed mechanisms by exploiting the compliance of the plastic to produce a monolithic 3D printed flexure translation stage, capable of sub-micron-scale motion over a range of 8×8×4 mm. This requires minimal post-print cleanup, and can be automated with readily-available stepper motors. The resulting plastic composite structure is very stiff and exhibits remarkably low drift, moving less than 20 µm over the course of a week, without temperature stabilisation. This enables us to construct a miniature microscope with excellent mechanical stability, perfect for timelapse measurements in situ in an incubator or fume hood. The ease of manufacture lends itself to use in containment facilities where disposability is advantageous, and to experiments requiring many microscopes in parallel. High performance mechanisms based on printed flexures need not be limited to microscopy, and we anticipate their use in other devices both within the laboratory and beyond.

“…Bellini and Guceri [4] carried out experimental work to find the stiffness matrix of an anisotropy behavioral FDM processed parts. Tymrak et al [14] compared the mechanical properties of the parts processed with an open source 3D printer and commercial available printers. Ning et al [15] investigated the effect of FDM process parameters on the tensile properties of the parts made of composite filament.…”

“…The elastic moduli for FDM processed layers (orthotropic material) are found experimentally by Casavola et al [27] and then classical laminate theory is employed to characterize the mechanical behavior of the FDM processed parts. So far, most studies [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] presented experimental work. However, there has been relatively little literature available on numerical modeling to find the elastic moduli of a material of the FDM processed part.…”

Abstract:In the present study, the mesostructure of a fused deposition modeling (FDM) processed part is considered for the investigation of its mechanical behavior. The layers of FDM printed part behave as a unidirectional fiber reinforced laminae, which are treated as an orthotropic material. The finite element (FE) procedure to find elastic moduli of a layer of the FDM processed part is presented. The mesostructure of the part that would be obtained from the process is replicated in FE models in order to find stiffness matrix of a layer. Two distinctive architectures of mesostructure are considered in the study to predict the mechanical behavior of the parts. Also, influences of layer thickness, road shape and air gap on the elastic properties of a material are investigated. Further, the parts fabricated with FDM process are treated as laminate structures. From the numerical results, it is seen that the elastic moduli are governed by mesostructures. Our laminate results are validated with experimental to demonstrate the use of classical laminate theory (CLT) for FDM parts. The elastic moduli (E 1 , E 2 , G 12 , ν 12 ) of a layer used in the analysis are calculated from FE simulations. This study establishes relationship between mesostructure and macro mechanical properties of the part.

“…Recently, a new 3-D printing method was developed and it had become popular because we can easily make complex and seamless parts using the method. Along with the expansion of the use of 3-D printing, researchers had focused on the effect of the laminated layers joins on the mechanical properties of the 3-D printed parts [4][5].…”

Observation of fracture behavior of 3-D printed specimens under rolling contact fatigue in water

Abstract. Polymer bearing was widely used in the corrosive conditions because of its high corrosion durability. The polymer bearing had been formed using molding and machining until the new 3-D printing method was developed. In this study, we performed the rolling contact fatigue tests of the 3-D printed specimens in water and observed the fracture behaviour of the specimens. We found that the surface cracks are related to both the rolling direction and the lamination directions.
