3D Printing technologies
- 2. Overview Introduction History Terminologies Process types in 3D Printing Materials Used in 3D Printing New Technologies in 3D Printing Applications Advantages Disadvantages 2
- 3. Introduction 3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as ADDITIVE MANUFACTURING. 3d Printing is a achieved using an additive process, where successive layers of material are laid down in different shapes. 3
- 4. History The technology for printing physical 3D objects from digital data was first introduced by Charles Hull in 1984. He named this technique as Stereo lithography and obtained a patent from this technique in 1986. In 1993, Massachusetts Institute of Technology (MIT) patented another technology, named “3 Dimensional Printing techniques”. Which is similar to the Inject technology used in 3D Printers. In 2006 Z Corp, Launched a breakthrough product, named Spectrum Z510, which was the first high definition colour 3D Printer in the market. 4
- 5. Terminology Additive Manufacturing:- It is defined as the process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies Rapid Prototyping:- Group of techniques used to quickly fabricate a scale model of a physical part or assembly using three dimensional computer aided design (CAD) data. Subtractive Processes:- Removal of material by methods such as cutting or drilling. 5

- 11. Latest Technologies in 3D Printing Australian manufacturer Aurora Labs have been developing a 3D printer which prints the metal parts at a speed of 3 Ton metal per day MELD Manufacturing Corporation has developed a new way to 3D print metals without melting the material. Tis technology has been in development over a decade, was first unveiled last year with the introduction of MELD B8 machine. HP’s Metal Jet, it enables the new technology in the 3D metal printing called Binder Jetting 11
- 12. Applications Design Visualization of Engineering Components. In Bio-Medical models like prosthetic arms, human skull. Electronic Modules Like Speakers, Television components, Computer components etc.., In Fashion technology, used to manufacture jewellery, foot wares etc.., In Archaeology, used to reconstruct the sculptures, monuments etc.., In Automobile industry for conceptual design of cars, bikes, other components. Aerospace industry for manufacturing aero engine with metal alloy. Testing of newly designed parts in industry. 12
- 13. Advantages Rapid prototyping. Wastage of material is almost negligible. Clean Process. Maintenance cost is less. Reduce the design Complexity. Easy to use. 13
- 14. Disadvantages Process is vey slow. Components do not have enough strength. Process is not suitable for mass production. Cost of Raw materials is high. Limitation in size of the job. Limited variety of Raw materials. Cost of 3D Printers are expensive. 14
