The method, which involves 3D printing, provides possibilities for the creation of innovative prototypes and technolo- gies for manufacturing. Our paper describes an idea of combining 3D printing with nanoclay. The addition of nanoclay will enhance the share of renewable raw materials that contribute to sustainable products. The structure of the filaments varies, however, as nanoclay is applied. The key goal of the paper is to establish methodologies for improving the properties of 3D composite filaments nanoclay and polyethy- lene. A comprehensive literature research including the extrusion, 3D printing and modern testing meth- ods, including the 3D scanning, was paired with a large experimental analysis to evaluate printed versions. 3D printing filaments were produced for different ratios of polypropylene and nanoclay in the extruder. Significant parameters were reported for the extrusion of related content. After the intro- duction of nanoclay, the dimensional flexibility of polypropylene was enhanced and the deformation of the 3D printed models decreased significantly. However, fragility in filaments and 3D models increased, with the increased nanoclay ratio. Ó 2020 Elsevier Ltd. All rights reserved.

Introduction Additive production, for what was called rapid prototyping (RP), is a more formal and standard term. More recently, the production of additives has become more widely known as 3D printing [1–3]. The process of rapidly generating objects from the 3D model data (CAD) system usually layer by layer is referred to by RP [4]. With the application of AM technology, the production of complex 3D objects without process planning has become simpler [5]. Many manufacturing methods, such as additive technologies, FDM, involve close study and, in certain situations, the machining or pro- cedures are quite complicated [6]. But only a simple understanding of system operation, properties of materials and model measure- ments were required in AM technologies [7]. In the recent years, additive manufacturing is research hot spot for the production of complicated designs and processing systems [8]. Being one of addi- tive manufacturing techniques, 3D printing is appropriate for high- profile applications and industries, mainly aerospace, automotive and biomedical [9–12]. In 3D printing [13], the filament is an object long, thread-like which, depending on the printer, has a width of 1.75 or 2.85 mm. These filaments are made from PLA and ABS fibers or plastics, and are the materials that are printed in the 3D design [14]. Each layer consists of a small transverse slice of CAD data in the layer- by - layer process [15]. In other words, the CAD program will carry out thousands of calculations to determine exactly how each layer is printed. The thickness of each layer determines how the product is finished. The thinner the layers, the closer are the finished pro- duct to CAD. The finished product is affected by the way in which they are merged and which material is used [16]. How long a CAD model is a true, functional commodity depends on the AM technol- ogy chosen [17]. Extrusion is the process of filament processing, which can be divided into two types: single-screw and double-screw extrusion. As this work will only examine the extrusion with twin tubes, it will not complete single-screw extrusion. Laser is the most com- monly used technology, and the technique has been utilized for landscape and architecture since the laser was introduced in the 1960 s. 3-D scanning is used for data collection and collection to https://doi.org/10.1016/j.matpr.2020.10.456 2214-7853/Ó 2020 Elsevier Ltd.
