3D Printing Manufacturing Techniques, Materials, and Applications: An Overview

Abstract

3D printing, also called additive manufacturing (AM), is a method of creating 3D solid parts from a digital document. By utilizing additive routes, the fabrication of 3D-printed objects can be made. These layers can be viewed as a gently cut level cross-area of the manifest object. 3D printing is somewhat in obstruction to subtractive manufacture, which is expelling/discharging out a touch of metal or plastic for the occurrence of a milling machine. 3D printing authorizes creating multifarious profiles employing fewer materials than conventional fabrication systems. This review article provides the general idea of 3D printing production techniques, materials used, and applications in the aircraft and automobile industry and biomedical fields.

Wind Tunnel Testing and Validation of Helicopter Rotor Blades Using Additive Manufacturing

“…In the selective laser sintering (SLS) technique, polymer powder is fused with laser. It is less costly than SLA and has good mechanical properties [10,34]. e SLS method is also used for working prototypes and is more expensive than the FDM model.…”

“…Models created in wood require a high cost for skilled workers, and it takes a long time to make the models. Metals like aluminum were used to prepare the model using CNC machines are high cost and less affordable [10,11].…”

Recent Advances on Electroconductive Hydrogels Used in Heart Repair and Regeneration

“…e ideal biodegradable EHs for cardiac tissue engineering have not yet been discovered [108,109]. With the fast advancement of 3D printing in the biomedical field [110], the technology may now be utilized to rapidly create bespoke tissue-constructing frameworks, heal tissue damage in situ using cells, and even directly print tissues and organs. 3D printing in conjunction with external electrical stimulation may be a viable approach for engineering cardiac structures [111].…”

Research on Manufacturing Technology of Complex Modeling Chinaware Integrated with 3D Printing Technology

“…Ceramic 3D printing technology is more and more mature with different processes [6]. Currently, there are 12 types of processes: direct writing forming DIW [7][8], ceramic clay extrusion disk forming CDM [9], stereo lithography (SLA) [10], digital light processing (DLP) [11], regional light transmission (LCD), selective laser sintering (SLS), selective laser melting (SLM), stereoscopic printing (3DP) [12], inkjet printing(IJP) [13], fused laminated forming (FDM) [14], layered solid forming (LOM), and two-photon polymerization (TPP) [15].…”
