“…Composite materials are much closer to materials produced by AM but there are two issues when it comes to applying the techniques for composites to 3D printing. First, in the majority of literature, the materials are modelled as isotropic 12,13,[15][16][17][18][19][20][21] or transversely isotropic, 22,25 which is not true of AM, where materials are highly anisotropic. [26][27][28] The second issue is that, with some exceptions, 17,20 the research employs a circular wire cross-section 29 due to ease of manufacturing and in calculations.…”

The helical spring is one of the most used components in mechanisms but there is little research on the application of 3D printing, also called Additive Manufacturing, to springs. Therefore, the objective of this paper is to derive a model for the stiffness of 3D printed springs. The equation assumes that springs are made of orthotropic material and with a rectangular wire cross-section, that is, die springs. A second version of the equation has also been postulated that accounts for the misalignment of the deposited tracks with respect to the direction of the coils due to the coil pitch. The two models are compared to various springs printed with PLA and ULTEM 9085 and are found to accurately predict the stiffness of real, 3D printed springs. These equations allow the design and manufacturing of helical die springs for applications with few load cycles and that require chemical and radiation resistance, such as in space. The equations are also the first step in the development of models for new kinds of springs, such as linear conical springs or hollow wire die springs.

“…Anh et al [19] studied the nonlinear vibration and dynamic response of stiffened FG cylindrical shells on elastic foundations in thermal environments. Recently, Liu et al presented a numerical model to predict compressive behavior of composite helical springs [20]. They have obtained more accurate results by including geometrical nonlinearity into their model.…”

This paper presents the development and implementation of integrated intelligent CAD (computer aided design) system for design, analysis and prototyping of the compression and torsion springs. The article shows a structure of the developed system named Springs IICAD (integrated intelligent computer aided design). The system bounds synthesis and analysis design phases by means of the utilization of parametric 3D (three-dimensional) modeling, FEM (finite element method) analysis and prototyping. The development of the module for spring calculation and system integration was performed in the C# (C Sharp) programming language. Three-dimensional geometric modeling and structural analysis were performed in the CATIA (computer aided three-dimensional interactive application) software, while prototyping is performed with the Ultimaker 3.0 3D printer with support of Cura software. The developed Springs IICAD system interlinks computation module with the basic parametric models in such a way that spring calculation, shaping, FEM analysis and prototype preparation are performed instantly.
