temperature controls. To print different materials multiple heads can be used. Research published on FDM extruder so far is very little. Adaptive filament deposition (AFD) and planar layer deposition (PLD) are the two patented techniques Tseng has for the freeform fabrication of metals and ceramics AFD uses a conical spindle which is kept inside a deposition head it is

Chapter 3: Fused deposition modeling 3.1. Introduction: Fused deposition modeling is a Rapid prototype process of producing the component by the extrusion process with the basic principle of the material deposition it layer above the other by fusing it to the layer just beneath. The input file for this process is in standard STL data format. Multiple build materials are can be used in this process as the build material and for the supporting material. Fused Deposition modeling was invented by

Additive Manufacturing(AM) is a manufacturing technology that creates objects rapidly with the help of Computer Aided Design (CAD) files. Different from traditional manufacturing method, additive manufactured models are usually stacked out by a serial of planer slices which are produced by processing wanted CAD designs with mathematical code. Stereolithography, commonly known as SLA, is one of the most applied forms of AM technology. Stereolithography researches were first appeared in 1970s, then

Objective The purpose of this work is to design a FDM based Rapid Prototype ie. 3D Printer which will corrects the errors found on other FDM printers and which provides high resolution and print size. To make the design cost effective FDM based printer is considered as cost of making it and cost of raw materials is very less. Resolution and material usage customization is great in FDM. Hot end temperature need to be adjusted when different material types are used. When required it is possible to

or thousands of horizontal layers. This is done with software. It can sometimes be done within a 3D modeling software application. Certain 3D printers require a certain slicing tool. Once the 3D modelTo begin 3D printing you first have to make a virtual design of the object that you want to create. The virtual design is a CAD (Computer Aided Design) file. A CAD file is created using a 3D modeling application or with a 3D scanner. A 3D scanner is used to make a 3D digital copy of an object. 3D scanners:

concerns issues such as printer model and prototype cost and level of user friendliness. Lastly, design series FDM printers are developed to make designs durable and dimensionally stable. Positives and Negatives of Using Fused Deposition Modeling (FDM) Technology Fused Deposition Modeling has become popular because of a number of reasons including low noise levels, reliability, high accuracy, professional finishes and office-friendliness. The technique can also be used to produce a wide range of materials

Acknowledgement The completion of this seminar wouldn't be possible without the participation and help of so many people whose names might not enumerated. Their contributions are sincerely appreciated and gratefully acknowledged. but I’d like to express my sincere gratitude to my guide prof. Mayur Makhesana sir And coordinator prof. Keyur Hirapara sir. To all friends and other who in one or another shared their support , either morally, or physically, Thank you. Harshad Vekariya

layers can be seen as a thinly sliced horizontal cross- section of the eventual object. It all starts with making a virtual design of the object you want to create. This virtual design is made in a CAD (Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object) or with the use of a 3D scanner (to copy an existing object). A 3D scanner makes a 3D digital copy of an object. 3D scanners use different technologies to generate a 3d model from something that

introduction about types of 3-D printers and variety of industries where they can be used, explanations regarding these aspects are as follows: i. STEREO LITHOGRAPHY (SLA) ii. FUSED DEPOSITION MODELLING iii. SELECTIVE LASER SINTERING (SLS) iv. MULTI-JET MODELLING (MJM) v. VFLASH PRINTER vi. FUSED FILAMENT FABRICATION (FFF) OR FUSED DEPOSTION MODELLING (FDM) Fundamentals of all types of printers stated above are same. As prototypes are printed layer by layer, so certain dimensions are required by printers
