Abstract

This is a research paper on 3D printing and the various materials used in 3D printing and their properties which become a notable topic in technological aspects. First, define what is meant by 3D printing and what is significant of 3D printing. We will go into the history of 3D printing and study about the process of 3D printing and what materials used in the manufacture of 3D printed objects and select the best materials among them which are suitable for our 3D printing machine. Also, see the advantages of 3D printing as compared to additive manufacturing.

I.INTRODUCTION 3D printing or additive manufacturing (AM) is a process formakinga3Dobjectofanyshapefroma3Dmodelorother electronic data sources through additive processes in which successive layers of material are laid down under computer controls. [1]Hideo Kodama of Nayoga Municipal Industrial Research Institute is generally regarded to have printed the first solid object from a digital design. However, the creditfor the first 3D printer generally goes to Charles Hull, who in 1984 designed it while working for the company he founded, 3D Systems Corp. Charles a Hull was a pioneer of the solid imaging process known as stereolithography and the STL (stereolithographic) file format which is still the most widely used format used today in 3D printing. He is also regarded to havestartedcommercialrapidprototypingthatwasconcurrent with his development of 3D printing. He initially used photopolymers heated by ultraviolet light to achieve the melting and solidification effect. [2]Since 1984, when thefirst 3DprinterwasdesignedandrealizedbyCharlesW.Hullfrom 3D Systems Corp., the technology has evolved and these machines have become more and more useful, while their price points lowered, thus becoming moreaffordable. Nowadays, rapid prototyping has a wide range of applications in various fields of human activity: research, engineering, medical industry, military, construction, architecture, fashion, education, the computer industry and many others. In 1990, the plastic extrusion technology most widelyassociatedwiththeterm"3Dprinting"wasinventedby Stratasys by name fused deposition modeling (FDM). After the start of the 21st century, there has been a large growth in thesalesof3Dprintingmachinesandtheirpricehasbeen dropped gradually. By the early 2010s, the terms 3D printing andadditivemanufacturingevolvedsensesinwhichtheywere alternate umbrella terms for AM technologies, one being used in popular vernacular by consumer - maker communities and the media, and the other used officially by industrial AM end use part producers, AM machine manufacturers, and global technical standards organizations.Both terms reflect the simple fact that the technologies all share the common theme of sequential-layer material addition/joining throughout a 3D work envelope under automated control. Other terms that had been used as AM synonyms included desktop manufacturing, rapid manufacturing, and agile tooling on-demand manufacturing. The 2010s were the first decade in which metal end use partssuch as engine brackets and large nuts would be grown (either before or instead of machining) in job production rather than obligatory being machined from bar stock orplate.
