The document is a presentation on 3D printing technology, detailing its introduction, working mechanism, applications, industry growth, and challenges. It highlights how 3D printing, or additive manufacturing, allows the creation of objects layer by layer from digital files and discusses its implications for manufacturing and commerce. Challenges include limitations in material use, design standards, speed, and cost of materials.

- 3. Introduction What is 3D Printing ? 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. 3

- 5. How it works ? A virtual design of the object is created. CAD (Computer Aided Design) uses a 3D modeling program or 3D scanner for virtual design. The software slices the final model into hundreds or thousands of horizontal layers. The printer creates the object layer by layer, resulting in one three dimensional object. 5

- 8. Industry Growth Will change the nature of commerce, because end users will be able to do much of their own manufacturing rather than engaging in trade to buy products from other people and corporations. 3D printing will change the manufacturing world with effects on energy use, waste reduction, customization, product availability, medicine, art, construction and sciences. 8
- 9. Challenges Inability to easily print in multiple materials on the same machine: Particularly plastic, metal and conductive materials. The colours are a touch dull and matt finish only. A decent standard for model designs: The current standard STL files have some limitations. A new standard has come through– the AMF file format, which solves many of the limitations of STL, but at this stage it is not as widely used. Speed: Printing is s…l…o…w. It takes a long time to build even the smallest piece. Most videos you see are sped up or cut so you are not sitting there for an hour while you build a medium sized toy for children. Cost: While the price of personal printers have come downwards tremendously in recent years, some even reaching only a hundred dollars, the materials used to 3D print are still quite costly. 9
