Abstract
Abstract3D printing manufacturing technology has garnered a lot of interest in recent years to simplify the fabrication of complex geometries and for its ability to work with a wide range of materials including but not limited to metals, ceramics, polymers, and composites. It also reduces the amount of material required and opens up the scope to print composites that are highly specific to the desired mechanical properties. This review article gives an overview of the common 3D printing methods such as fused deposition modeling, selective laser sintering, stereolithography, and digital light processing. Additionally, it focuses on the 3-D printer materials, the scope of the 3D printed parts and discusses the limitations of each technique in order to encourage further research in this field.KeywordsSelective Laser Sintering (SLS)Stereolithography (SLA)Fused Deposition Modeling (FDM)Digital Light Processing (DLP)Acrylonitrile Butadiene Styrene (ABS)Poly Lactic Acid (PLA)
