FACTOR ANALYSIS OF PHOTOPOLYMER RESINS FOR 3D PRINTING

Abstract

3D printing is one of the key elements of Industry 4.0, which is the fourth industrial revolution. This technology allows you to create objects with three-dimensional shapes from various materials, including metals, plastics, ceramics and others. It is used in many industries, including medicine, aviation, automotive and engineering. The main advantage of 3D printing is the ability to create objects without a large amount of production and tooling costs. Instead, 3D printing allows you to create objects directly from digital models, which reduces production time and costs. Photopolymer 3D printing has a number of advantages, such as affordability, high precision of manufacturing parts, simplicity of technology and a large number of free software. Due to these advantages and features of the technology, this manufacturing method can be used in many areas, such as radio electronics (development of cases), jewellery production (creation of master models for casting), dentists (creation of dental prostheses), creation of decorative models for interior design.

The authors studied the influence of different brands of photopolymer resins on the accuracy of the geometric dimensions of the model and the presence of defects in 3D printing using LCD technology. To verify this, the authors conducted a factor analysis of the photopolymer resins most commonly used for photopolymer printing using IBM SPSS26. They also produced test samples at different settings of the print profile in the Chitubox software with different model exposure parameters.
