This document provides an outline and overview of 3D printing. It discusses the history of 3D printing, which was first developed in 1984. It then defines 3D printing as a process that creates 3D objects by laying down successive layers of material based on a digital file. The document outlines the general principles of 3D printing, including modeling an object digitally, printing it by adding layers, and sometimes finishing the printed object. It also discusses some common 3D printing methods and potential advantages and disadvantages.

- 1. Md. Foyaz Ullah CSE–38(evening) Roll: 201411038150 Presented by: Anowar Hossain CSE-38(evening) Roll: 201411038148 Bangladesh University
- 2. Outline Introduction History What is 3D Printing? General Principal How it’s work? Different method of 3D Printing Advantage Disadvantage Calculation
- 3. Introduction 3D printer is a modern technology in which 3 dimensional objects are printed from digital data Three dimensional object is created by laying down successive layers of materials.
- 4. History The technology for printing physical 3D object from digital data was first developed by Chuck Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1984.
- 5. What is 3D Printing? 3D Printing is a form of additive manufacturing in which components are fabricated in an additive fashion by adding successive layers of materials together. It is also know as: Rapid Prototyping Additive manufacturing. 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created.
- 6. How 3D Printer Work????
- 7. How 3D Printing work 1. A person created a of an item using a computer aided design Software Program. 2. The CAD information is send the printer. 3. The Printer forms the item by depositing the materials in layers, Starting from the bottom layers on to a platform. In some cases light or lasers used to harden the materials.
- 8. How 3D Printing work
- 9. General Principles Modeling Printing Finishing
- 10. Modeling Additive Manufacturing tasks virtual blueprints form computer aided design (CAD) or animation modeling software and “Slices” them into digital cross-sections for the machine to successive use a guideline for printing.
- 11. Printing The perform a print, The machine read the design and lays down successive layers of liquid, powder, or sheet materials to build the model from a series of cross sections. These layers, Which cross ponds to the virtual cross section from the CAD model, are join together or automatically fused to create the final shape. The primary advantage of this technique is its ability to create almost any shape or geometrical feature.
- 12. Finishing Though the printed product resolution is sufficient for may applications, Printing a slightly oversized version of the descried of in slandered resolution, and the removing materials with a higher-resolution subtractive process can archive a higher-resolution.
- 13. Different Methods Stereo lithography Selective laser sintering (SLS) Fused deposition modeling (FDM) Ink-Jet 3D Printing
- 14. Value proposition of 3D Printing Fabrication on demand Shorter Product development time due to rapid prototyping Less reliance on logistics Mass Customization Caters to each individual’s wants and needs instead of mass production and consumption
- 15. Advantages Print movable parts Print Items in remote locations Ability to send items over internet and print out at home Plastic use is strong
- 16. Disadvantages No regulations on what can be made example weapons Kids could print out dangerous Items Provide advantages for criminals Counterfeiting Expansive
- 18. Conclusion Nothing communicates ideas faster than a three dimensional parts or model. With a 3D printer you can bring CAD file and design ideas to life- right form your desktop. Test form, Fit and function as and many design variations as you like with functional parts.
