Transcript of 3D-Printers Presentation
FET/CS(F)/242 3D-Printers 3D printing 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. History Agenda 1.
6. What is a 3D - Printer? History How does it work? Pros/Cons Applications Future Scope/Conclusion How does it work? Pros / Cons Software Pros Cons Methods of 3D Printing 1. Steriolithography

4. Electron Beam Melting
5. Multi-Jet Modeling
6. Fused Deposition Modeling Pros Cons Software Used Auto CAD
etc... Stereolithography Digital Light Processing Selective Laser Sintering Electron Beam Melting Multi-Jet Modelling Fused Deposition Modeling Uses a high power laser to fuse small particles of plastic, metal (direct metal laser sintering), ceramic, or glass powders into 3D-Products. Stereolithography More accurate
Smooth surface Limited Material Options
Color models cannot be created Digital Light Processing Pros Cons Selective Laser Sintering Stronger Material
More Material Options: Thermoplastics, Metal Powders, and Ceramic Powders More Inaccurate
No Custom Colours Supported Uses Titanium Alloys and Chrome Material

Stereolithography to create
3D models before manufacturing MIT introduces layer by layer 3D printing, later licensed to Z Corporation. This method is like a regular ink jet printer except it prints upwards in 3D rather than across in 2D. 3D printer were costly and mostly used for industrial modeling until RepRap (replicating rapid prototyper) was announced in 2006 RepRap went on sale and was capable of producing 50% of its own parts making it the first self replicating 3D printer 3D printing started to become thought of as more than just a prototyping tool and more of a manufacturing tool. 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 or with the use of a 3D scanner The software slices the final model into
hundreds or thousands of horizontal layers.
When this prepared file is uploaded in the
3D printer, the printer creates the object layer by layer.
The 3D printer reads every slice (or 2D image)
and proceeds to create the object blending
each layer together with no sign of the layering
visible, resulting in one three dimensional object. Input Process Output Digital input Solid 3D object The material begins as a liquid and changes to a solid when hit by a concentrated beam of ultraviolet light. Simmilar to SLA, except object starts as a vat of full liquid. takes place in a vacuum; begins by spreading down a layer of metal powder (most often titanium). An electron beam melts the powder into a solid layer. It spreads a layer of resin powder and
then sprays a colored binding glue-like substance that hardens the powder
into a single layer. uses a heated extrusion nozzle that melts a material (e.g., plastic) as it comes out, which hardens almost immediately. It can move around both horizontally and vertically
