3d printing is like printing a 3 dimensional object, like 2d printing in which we print matter in a 2d paper similarly 3d printing is done by combining all those 2d layers by the computer with the measurements which we give to the software. Sounds great, doesn’t it? now this technology is improving rapidly. 3D printing in the term’s original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently the meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering based processes. Technical standards generally use the term additive manufacturing for this broader sense.
This is a great video by TED, actually must watch…
This is what a 3D printer can do.
With this advancements 3d technology is serving medical field greatly, the people who lost their body parts in accidents and so can be give 3d printed parts with exact shape and size. By this we can surely think of manufacturing automobiles, civil engineers can test their plans by 3d printing their plan’s miniature.
The most crazy thing with this is we are now able to print food materials with 3d printing, don’t believe me? check out this crazy video from CES 2015- https://www.youtube.com/watch?v=MGxr3boyIus.
informatic cool stuff
