3d printing is a cutting edge phenomenon. It enables a person to touch and feel an innovation instantly. A picture may be self-explanatory but if you are an innovator, you would like to present your creation in its full form. However, getting a model ready takes weeks and months.
If you are in the business of making new products, you need to introduce your product through a prototype. You want the client to have a fair idea of what you have designed. However, a picture may not do justice to your invention. 3d Printing is an invention that can be called a Eureka moment invention. It has changed the expectation of the client from an innovator. People want to see, touch and feel what they are about to invest in. These printers work like inkjet printers. The print layer by layer, hence forming a model at on fifth the cost of a model. The time taken is also much lesser than the handcrafted models.
The CAD (computer-aided design) and laser models ruled the industry. Designing and modeling often took months to complete. The prototypes were rigorously carved and stuck together. The models costed a bomb. Even after the prototype was ready, it was impossible to make changes and clarify. In the 1980s, a rapid prototype(RP) was invented. Sophisticated machines were used to develop models in hours.
How Does A 3d Printer Work?
For example- if you have to make a car prototype, you will have to take a wooden block and start carving it like a sculptor. While you are carving it, you have to make sure that it is a scaled model to give a perfect idea of the car’s dimensions. The intricate precision may require days, weeks or even months. However, a 3d printer will take just a few hours to develop the car of your dreams. You just have to have all the dimensions and the design ready on your computer system. Voila! Your car prototype is ready. The 3d printer takes the CAD Drawing and converts into a 3d model through its exceptional technique of layer by layer printing.
The ink used by 3d printer is different from the standard liquid infused by an inkjet printer. It uses molten plastic through tubes that take instructions from the computer. The printer then waits for one layer to dry up and then puts on the other layer. So on and so forth. The plastic used is the same one used to make Lego bricks. It is recyclable plastic which makes it less harmful to the environment. The plastic does not melt if let in the sun. You can even paint or sand smooth the 3d model once it dries up. Colours can be added to this plastic and you can have a colourful model.
