Abstract
3D printing of a composite structure with shape memory materials requires a special approach to the subject, at the stage of the design and printing process. This paper presents the design steps during the development of a 3D-printed composite structure with shape memory material. The connection points between the SMA fibers and the printer filament are developed in the MATLAB environment. Finite element method is used to simulate the shortening of the shape memory material under the influence of temperature and its effect on the printed polymer material is presented. In the MATLAB environment, evolutionary algorithms were used to determine the shape of the SMA fiber alignment. This work demonstrates the use of shape memory effect in 3D printed smart composite structures, where the component takes a predetermined shape. The structure obtained as a result of such printing changes with the heat generated by the current voltage, making it the desired fourth dimension.
Highlights
The beam was split into a finite number of elements, where the Shape memory alloys (SMA) fiber a actuator was replaced by a concentrated force applied at the cross-section, where the runs parallel to the beam axis
In a MATLAB environment, the model is read from the file and subjected to further first step, test simulations were carried out to select the appropriate par of the genetic algorithm to obtain correct results in a short time
The designed composite structure deforms according to assumptions, software
Summary
The combination of 3D printing with smart materials to obtain predetermined deformation characteristics of the printed material is somewhat novel. The heating martensite to the austenite phase and restoration of the programmed shape The structure of this component to the characteristic temperature causes the transformation of martensite after deformation returns to its original form in the temperature range shape. This effect, the shape of the high-temperature parent phase and the low-temperature memory alloys are used, among other materials, as permanent mechanical and martensitic phase mustShape be subjected to a repeated thermo-mechanical treatment, referred electrical connections, as heat engines, control systems, valve systems, vibration damping to as training. SMA masters requires a complex process for electrical connections, The as heat engines, control systems, systems, vibration damping their training The solution to this problem can be the creation of any shape of actuators systems, actuation systems, diagnostic systems, and applications in biological organisms or sensors using incremental technologies. The tests, on the other hand, included the creation of structures using FDM printing technology and qualitative verification of the deformation of the structure after its activation
