3D Printing Technology PPT by ajaysingh_02
- 2. 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 isalso known as rapid prototyping, is a mechanized method where by 3D objects arequickly made on a reasonably sized machine connected to a computer containingblueprints for the object. This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.
- 3. 3D printing is the perfect manufacturing method to use if you need to do some rapid prototyping. ... By using 3D printing you save time on your assembly process. Mechanical 3D p r i n t i n g e n a b l e s t h e production of a batch of parts that are traditionally made of many component
- 4. 3D Printers are machines that produce physical 3D models from digital data byprinting layer by layer. It can make physical models of objects either designed witha CAD program or scanned with a 3D Scanner. It is used in a variety of industriesincluding jewelry, footwear, industrial design, architecture, engineering andconstruction, automotive, aerospace, dental and medical industries, education andconsumer products.
- 5. PRINCIPLES • The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of analysing and collecting digital data on the shape and appearance of a real object. Based on this data, three-dimensional models of the scanned object can then be produced.
- 6. 3D PRINTING • 3D printing consists of an inkjet printing system • Layers of a fine powder are selective bonded by printing an adhesive from the inkjet print head in the shape of each cross section as determined by a CAD file
- 7. 3D PRINTING • It is also recognized as the fastest method • These photopolymer phase machines use an ultraviolet flood lamp mounted in the print head to cure each layer as it is deposited
- 8. Definition:- 3D + Printing = 3D Printing 3D Printing is a p h r a s e u s e d t o d e s c r i b e t h e process of creating three objects from digital file using a materials printer, in a manner similar to printing images on paper.
- 9. Printing process Printing is a process for reproducing text and images, typically with ink on paper using a print press.
- 11. History of 3d Printing • The technology for printing physical 3D objects from digital data was first developed by Charles Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1986. • While Stereo lithography systems had become popular by the end of 1980s, other similar technologies such as Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) were introduced.
- 12. The Basic Process of 3D Printing • 1.Create a CAD model of the design • 2.Convert the CAD model to STL format • 3.Slice the STL file into thin cross-sectional layers • 4.Construct the model one layer atop another • 5.Clean and finish the model
- 13. FINISHES 3D-printing is usually considered as a great technology for ready-to-use object, but for many projects, an additional treatment of the surface or the part is needed to reach the desired rendering. To learn more about available finishes at Sculpteo and when to use them or to get good tips from our team for the different steps post-3D- printing, you can refer to the following documents.

- 17. SLS method Selective laser sintering (SLS) is an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering),ceramic or glass powders into a mass that has a desired 3-dimensional shape).

- 19. Stereo lithography is an additive manufacturing process using a vat of liquid UV-curable photopolymer ” resin” and a UV laser to build parts a layer at a time.
- 20. FDM Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications.
- 21. Laminated object manufacturing Laminated object manufacturing (LOM) is a rapid prototyping system developed by Helices Inc. In it, layers of adhesive- coated paper, plastic or metal laminates are successively glued together and cut to shape with a knife or laser cutter.

- 25. 3D printing Vs conventional technologies 3DP does not and will not replace completely conventional technologies such NC and high-speed milling, or even hand-made parts. Rather, one should regard 3DP as one more option in the toolkit for manufacturing parts. Figure depicts a rough comparison between 3DP and milling regarding the costs and time of manufacturing one part as a function of part complexity10. It is assumed, evidently, that the part can be manufactured by either technology such that the material and tolerance requirements are met.
- 27. Types of Material Used There are Many different materials can be used for 3D printing, such as ABS plastic, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers and polycarbonate

- 30. ADVANTAGES • Clean process • Wastage of material is negligible • Good for job production • 3D printing technology requires no toxic chemicals like those used in stereo lithography printing technology
- 31. ADVANTAGES • It is also the fastest printing method • More affordable • easier to use than other technologies
- 32. DISADVANTAGES • Process is very slow • Components do not have enough strength • Process is not mass production
- 34. As anticipated, this modern technology has smoothed the path for numerous new possibilities in various fields. The list below details the advantages of 3D printing in certain fields. 1. Product formation is currently the main use of 3D printing technology. These machines allow designers and engineers to test out ideas for dimensional products cheaply before committing to expensive tooling and manufacturing processes. 2. In Medical Field, Surgeons are using 3d printing machines to print body parts for reference before complex surgeries. Other machines are used to construct bone grafts for patients who have suffered traumatic injuries. Looking further in the future, research is underway as scientists are working on creating replacement organs. 3. Architects need to create mockups of their designs. 3D printing allows them to come up with these mockups in a short period of time and with a higher degree of accuracy. 4. 3D printing allows artists to create objects that would be incredibly difficult, costly, or time intensive using traditional processes.
- 35. What will be in the future? For many products the standard conveyors can be greatly reduced or completely replace by 3D- printer, because the end product - for example, a car - will not be collected from hundreds or thousands of individual parts but will be produced in one process
- 36. SUCCESS STORIES
- 37. SUCCESS stories Auto parts: for example, parts of "Formula 1" car engines, are made by direct laser sintering of metal; Aircraft parts: F-18 (fight aircraft) tube for the control system environment; Individual orthodontics: the company Align Technology uses the 3D Printing to generate accurate individual dental braces for hundreds of thousands of patients worldwide by stereolithography from 3D-scans of the mouth; polymer is used as a material for the production of staples; Individual hearing devices: manufactured by companies Siemens and Phonak, based on 3D-scan of the ear canal, so that the device is ideally suited to the user;
