As a student of electronics, I had to learn visualising the things, things that can be just drawn or not be seen by eyes. i had imagined electron fighting with each others and electricity and signals flowing. But Today I got a shock with this news of Microsoft HoloLens. It uses the Holograms and just change the world we look digitally. I cant express what it can do so I share the l;ink visit it and see a glimpse of future of our digital generation.
check this website see the videos here and get astonished:
Last week china had made a history by printing 10 houses of 300 feet heights in 24 hrs, using 3D printers , and scientist had made a tumour model for study of typical concepts of this tumour using same technology. Lets know what and how about this technology here.
3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. The 3D printing concept of custom manufacturing is exciting to nearly everyone. This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts. Now, you can create a
complete model in a single process using 3D printing. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.
3D Printers are machines that produce physical 3D models from digital data by printing layer by layer. It can make physical models of objects either designed with a CAD program or scanned with a 3D Scanner. It is used in a variety of industries including jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education and consumer products
The model to be manufactured is built up a layer at a time. A layer of powder is automatically deposited in the model tray. The print head then applies resin in the shape of the model. The layer dries solid almost immediately. The model tray then moves down the distance of a layer and another layer of power is deposited in position, in the model tray. The print head again applies resin in the shape of the model, binding it to the first layer. This sequence occurs one layer at a time until the model is complete.
Above is a flowchart of the printing process.
