Abstract

In recent years, additive manufacturing (AM) has emerged as the most
revolutionary technology in manufacturing, playing an indispensable role in many
important areas due to its outstanding precision, ability to fabricate complex
structures, and short production cycles. At the same time, the development
of this technology has been accompanied by a constant search for materials
suitable for it. These materials play important roles in the industry, have excellent
properties but are difficult to process using traditional manufacturing methods,
or are newly developed materials specifically for AM. While these explorations are
being undertaken, attention to standards in the field will ensure that research is
accelerated and on the right track. This paper presents each of the seven technique
categories of AM. The focus of this paper is on the emerging materials for AM, such
