ABSTRACT Additive manufacturing (AM) or additive layer manufacturing is the commercial manufacturing name for 3-D printing, a computer-managed technique that creates 3-dimensional objects with the aid of using depositing materials, commonly in layers. These methods are categorised usually in line with the sort of material used as liquid-based, solid-based, and powder-based additive production methods. Solid based additive production is hugely used due to its ease of use, low price, and reasonably-priced material. Powder-based additive production is used for 3-D printing with metal substances. Metal additive production technology is the most costly among numerous additive manufacturing methods. Liquidbased additive manufacturing methods usually use photopolymer liquid resin as a raw material. It offers a completely high-quality surface finish therefore used withinside the jewelry industry and dental industry. The price of the liquid-based additive production technique is medium regarding solid-based and powder-based additive production methods. Digital Light Processing (DLP) is a liquid-based additive production technique. Keywords: Additive manufacturing, 3D printing, rapid prototyping, DLP 3D printing.

INTRODUCTION
Additive Manufacturing refers to a technique by which digital 3-D layout information is used to build up a physical component in layers with the aid of using depositing material. The term "3-D printing" is increasingly used as a synonym for Additive Manufacturing. Term Rapid Prototyping is also used for Additive Manufacturing. Rapid prototyping is a collection of strategies used to quickly fabricate a scale version of a physical component or assembly the use of 3-dimensional computer-aided design (CAD) information. Construction of the component or assembly is generally carried out the use of 3-D printing or "additive layer manufacturing" technology. However, 3-D printing is a greater correct term, in that it describes an expert manufacturing approach which is different from traditional strategies of material removal. In Additive Manufacturing in preference to milling a workpiece from a solid block, builds up components layer by layer using materials that are available in high-quality powder form, a liquid form, or solid wire form. A variety of various metals, plastics, and composite materials can be used.

LITERATURE REVIEW
Pil-Ho Lee et al. (2014) mentioned dimensional accuracy in additive manufacturing (AM) methods and concluded that the development of dimensional accuracy is one of the most important scientific challenges to enhance the characteristics of the goods by AM. This paper analyzed the research for typically used AM techniques regarding dimensional accuracy and categorized them by process characteristics, and relevant accuracy problems are examined. Tyge et al. (2015) mentioned the characterizing of DLP 3-D Printed Primitives, Studied the resolution and reproducibility of 3-D printing methods. Centroid, rectangularity, roughness, and tilt of the top of a primitive were observed. Concluded that standard deviations for these estimates were quite small. The method was shown to have high precision when compared to a visual inspection by an expert. www.irjmets.com
