Investigation of metallic 3D porous scaffold prepared by selective lasintering for dental applications

Abstract

This article examined the history of three-dimensional (3D) metal printing technology, various types of methods, and their advantages and disadvantages. Selective laser melting (SLM) was compared with regards to consumables, working methods, limitations, capabilities, and applications. Examining each method in turn reveals that the superiority of each one depends on the materials that are intended to be used as the basis of any type of light or heavy parts. The prepared sample by SLM process, which belongs to the family of 3D printing, is fusion powder, and the materials used in both processes are granular metals. This technology is suitable for complex parts, which cannot be made by traditional methods due to their high cost, with excellent mechanical properties for the industry, plastic, and dentistry applications. This technique uses metal 3D printing technology with various levels of porosity. Every day, metal printing provides greater benefits to industries. However, this technology has its own disadvantages, which include its lack of both suitablity and cost-effectiveness for manufacturing parts with traditional methods. © 2023, Iranian Chemical Society.
