Fused Deposition Modelling (FDM) is a fast-growing 3D printing technology. This technology expands rapidly even in households. Most users set print parameters only according to their own experience, regardless of the final mechanical properties. In order to predict the mechanical behaviour of the FDM-printed components, it is important to understand not only the properties of the printing material but also the effect of the printing process parameters on the mechanical properties. Components manufactured by FDM technology have an anisotropic structure, therefore the filling angle, fill shape, air gap, print orientation, and print temperature affect the resulting mechanical properties. This work deals with the change of mechanical properties depending on the setting of the filling angle, the shape of the filling, the orientation of the parts during printing, the influence of the material and pigment manufacturer.

Abstract Rapid prototyping (RP) uses a cycle where a real model is made by explicitly adding material as thin cross-sectional layers. Fused deposition modelling (FDM) 3D printer is being use for synthesis of ABS based bone hammer. Response surface methodology (RSM) based L27 design of experiment were adopted to perform the experiment using four influencing parameters such as layer thickness, infill percentage, orientation and nozzle temperature for the three responses deflection, hardness and weight. Response surface methodology was used for modelling and optimization of considered process parameters. In present investigation, it is evident that bone hammer fabrication process parameters have been optimized on data such as bone hammer weight 19.8091g, hardness 104.5921 BHN, and force of 15 degree deflection 36.0681 N has been produced with RSM prediction with influence of process parameters such as layer thickness 0.250 mm, infill percentage 63.3333, orientation 60 degree, nozzle temperature 240°C.

Purpose Fused deposition modelling (FDM) is increasingly being explored as a commercial fabrication method due to its ability to produce net or near-net shape parts directly from a computer-aided design model. Other benefits of technology compared to conventional manufacturing include lower cost for short runs, reduced product lead times and rapid product design. High-performance polymers such as polyetherimide, have the potential for FDM fabrication and their high-temperature capabilities provide the potential of expanding the applications of FDM parts in automotive and aerospace industries. However, their relatively high glass transition temperature (215 °C) causes challenges during manufacturing due to the requirement of high-temperature build chambers and controlled cooling rates. The purpose of this study is to investigate the mechanical properties of ULTEM 1010, an unfilled polyetherimide grade. Design/methodology/approach In this research, mechanical properties were evaluated through tensile and flexural tests. Analysis of variance was used to determine the significance of process parameters to the mechanical properties of the specimens, their main effects and interactions. The fractured surfaces were analysed by scanning electron microscopy and optical microscopy and porosity was assessed by X-ray microcomputed tomography. Findings A range of mean tensile and flexural strengths, 60–94 MPa and 62–151 MPa, respectively, were obtained highlighting the dependence of performance on process parameters and their interactions. The specimens were found to fracture in a brittle manner. The porosity of tensile samples was measured between 0.18% and 1.09% and that of flexural samples between 0.14% and 1.24% depending on the process parameters. The percentage porosity was found to not directly correlate with mechanical performance, rather the location of those pores in the sample. Originality/value This analysis quantifies the significance of the effect of each of the examined process parameters has on the mechanical performance of FDM-fabricated specimens. Further, it provides a better understanding of the effect process parameters and their interactions have on the mechanical properties and porosity of FDM-fabricated polyetherimide specimens. Additionally, the fracture surface of the tested specimens is qualitatively assessed.

In this research the influencing process parameters on fused deposition modelling of Acrylonitrile Butadiene Styrene (ABS) parts were studied. The two process parameters, layer thickness and model interior fill style are studied. The specimens were built, tests carried out to find out the surface roughness quality of the specimens. The results analyzed using Response Surface Methodology (RSM). The result indicates that the specimen Type 1 with the 0.254mm layer thickness and solid model interior fill style is the best specimen among the types of specimens tested.

Abstract Soft, ultra-stretchable thermoplastic elastomers have recently became available for use with desktop, fused deposition modeling printers. However, the effects of additive manufacturing process parameters on final mechanical properties are presently not well-known for this class of materials, making predictive modeling and product design difficult. Here we perform a design of experiments investigation of an elastomeric material that the manufacturer claims to have up to 580% strain at fracture. Within the investigation, two factors, extrusion temperature and layer height, are selected as independent variables and mechanical properties are extracted as dependent variables based on quasi-static tension tests following ASTM D412. Primary statistical results, based on an Analysis of Variance, indicate that hotter extrusion temperatures exhibit higher Young’s moduli (at small strain), lower ultimate tensile strength, and higher fracture strain. Further, the layer thickness is not a factor unless evaluating performance at small strain, in which case it is significant and thicker layers will yield higher Young’s moduli. Several popular hyperelastic constitutive models are calibrated to our tensile data, and a preliminary finite-element simulation of a soft prosthetic finger is performed to demonstrate the potential role of predictive simulations in 3D-printed product design.
