The field of bioprinting, using 3D printing technology for producing live cells with extreme accuracy, could be the answer to many of the problems we as humans face in the medical field. It could be the end to organ waiting lists and an alternative for organ transplants. In 3D printing technology lies the potential to replace the testing of new drugs on animals. However, the idea of applying 3 dimensional printing to the health industry is still quite new and yet to have a major impact. Manufacturing working 3D organs remains an enormous challenge, but in theory could solve major issues present today.
The process starts with a concept or idea. The first stage of 3D printing is planning out this concept with either computer aided design or animation modeling software. There are tons of programs out there today with these capabilities. Google SketchUp for example is known for being easy to use. Using some easy tools that can be learned quickly, edges and faces can come together to make very intricate models. It can even be used with Google Earth. All those models of the world in that software are made in what is basically the same process digitally. Blender is the free 3D creation program that exists for the needs of major operating systems. It is a high end software containing features that are much more capable than Google SketchUp. Tinkercad is a newer way of creating designs for 3D printers and works slightly faster than the others. Containing only three simple tools, it’s effectiveness for creating models is among the best..
Every single program will be able to create a virtual diagram and outline of the concept being implemented on the printer. Then the program divides the concept into digital cross-sections. This is so the printer is able to build it one layer at a time. The digital cross-sections act as guidelines for the printer to follow. With this action, the printer will make the object from the digital concept the exact size and shape desired. This process in printing a 3 dimensional object can take up to the same amount as the actual printing itself and sometimes even more. Everything depends on the complexity of the concept. Every little detail is made out by the printer so the digital blueprint has to be exactly as desired.
The technology of 3 dimensional printing has been growing rapidly. So much that now with less than $1000 anyone could buy their own 3D printer kit and build one themselves. Granted, the process of putting it all together will take a bit of time. It’s not easy, but anyone that’s good with their hands will enjoy piecing it together. Why someone would need a 3D printer in their house is still somewhat baffling, but ton’s of interesting things could be made for everyone in the family.
3D printing uses a process known as "additive" manufacturing. That means that the solid, three-dimensional object constructed will be made by adding the desired material in layers. The first successful outcomes of additive printing...
