Abstract
Additive manufacturing (AM), also known as 3D printing, is a technology that allows the creation of three-dimensional objects by adding material layer by layer based on a digital 3D model. Among the different technologies of 3D printing available material extrusion technology (MEX) is the most popular because of its simplicity and low cost. This equipment can use different position systems such as the cartesian printing system, which uses a 3D printer with three axes to control the extruder's position. Also, there are different types of raw materials that can be used in MEX technology, such as polymers, ceramics, composites, etc. These materials can be used in different feedstock forms such as filaments, pellets, or paste. By using paste extrusion technology, it is possible to create complex and precise ceramic parts using a 3D printer. This research aims to review this subject in order to find out printed ceramic results with high variability and quality for different purposes. To do so, this review will focus on pastes using ceramics, such as alumina, hydroxyapatite (HAp), and zeolite, and the properties of these ceramics for use in AM, gathering information about the methods of paste production, reagents, additives used, and their benefits to the process. Concerning the desirable printability, this research would clarify if these materials and the process can maintain the filament form, not tear apart during the printing process, and retain its structure during the subsequent steps of ceramic parts production. To conduct this review, it was used R programming language to run the bibliometrix algorithm for selecting articles from the Web of Science and Scopus databases. Following, the articles were filtered using relevant keywords to identify the most appropriate studies. After finishing the review, it was concluded that the materials obtained with alumina, hydroxyapatite, and zeolite are printable using proper reagents and additives to produce the ceramic paste using a piece of specific equipment This research provides valuable insights into the production of ceramic paste and the factors that influence its printability. Through this knowledge, it will be possible to advance in laboratory practices to produce AM ceramic parts in research activities.
