3D Printing by Vladimirs Pankratovs 3D 2D D -D ... ? puter graphics are graphics which are using three dimensional representation of geometric data ( by Wikipedia )Printing process ? Printing is a process for reproducing text and images, typically with ink on paper using a print press. 3D + Printing = 3D Printing 3D Printing is a phrase used to describe the process of creating three objects from digital file using a materials printer, in a manner similar to printing images on paper. Different methods ?Selective laser sintering (SLS) ?Stereolithography ?Fused deposition modeling (FDM) ?Laminated object manufacturing SLS method (not SLS Mercedes) ?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 SLS method STEREO LITHOGRAPHY ?Stereolithography is an additive manufacturing process using a vat of liquid UV- curable photopolyme r ”resin ” and a UV laser to build parts a layer at a time. FDM ?Fused deposition modeling (FDM ) is an additive manufacturing monly used for modeling, prototyping, and production applications Laminated object manufacturing ?Laminated object manufacturing (LOM ) is a rapid prototyping system developed by Helisys Inc. In it, layers of adhesive-coated paper, plastic or metal laminates are essively glued together and cut to shape with a knife or laser cutter.
