Mike posted an article involving sophisticated 3-D printing machines at lower cost for the population. Today the cheapest AM machine has a minimum price of $5000, and thus not readily available for the general population. There are hints that a metal laser sintering machine will have reduction in costs, however these costs will still probably be still high. The article describes two methods of expanding the availability of these printers and lowering their future costs. One is by developing materials and methods for use in existing consumer processes, such as FFF. One example,is by using the metal filler rod as a filament and an electric arc as the heat source. The other is by creating a process that integrates a proven technology into a low - cost system, such as leveraging existing inkjet technology into 3-D printing. Think about the application of this into the future. The majority of the population does not have access to basic service and basic materials. With a sophisticated and low-cost 3-D printer people will be able to buy cheap raw materials and print wrenches, forks, knives, plates, and basic necessity tools. Not mentioning that they can possibly print a house in the future and house objects like door parts, window frames, and beams.

Today I presented about 3-D printing in the medical field. Researchers from the University of Sydney and Harvard are developing 3-D printed blood vessels and tissues to be future implemented in patients. In the future, printing organs and printing limbs will be a good area of research for doctors who have ambition in expanding their research. The good thing about printing organs is that there will not be a great need for donors, reducing the risk of human fatality. Also imagine using this printer for replacing someone's arm of finger in the future. Possible reconstruction of muscles and bones are also a possibility. Using human tissue to heal and replace damaged parts are definitely an important step to cure several diseases and deformities in our bodies today.

You know, it is very interesting how 3-D printing is popular now a days. Before no one used to talk about it, nobody knew what exactly this "new" type of printer could do. In the present, people have been benefitted from aluminum parts with a precision of 2/1000in to composite materials fitting Boeing 747s. How to understand and process this new type of technology is still being digesting in society. For many people, printers mean printing paper with an ink, and to extreme cases, printing presentation projects. A lot of doubts come from the fact that solid and objects are now being printed from these machines, which sometimes require raw materials that are cheaper than a colored ink cartridge. Once this gets going and attractive to society, the horizons are infinite on what these machines can achieve -driven by of course people's needs. To be sitting on an office writing about how 3-D printers will change the world is like writing about airplanes 100 years ago. Questions like "will this thing be able to fly" or like "can it really be done" are always present and circulating day by day. How to explain the future? How to tell someone 10 years from now that reality will be so different from today? 20 years? 50 years? It is a hard question to solve, but certainly based on past experiences, we know the human kind is going forward in this area.
