3D printing involves the process of making or creating a real three dimensional object. The objects created by the 3D printer can be plastic, nylon, metal and many other types of materials. It is used to print end user products, manufacturing prototypes, aircraft engine parts and also even by using the human cells it can able to build organs. What is 3D printing? The other name for 3D printing is called as additive manufacturing. 3D printers utilize variety of different additive manufacturing technologies. All those technologies share one core matter in common. That is they create 3D objects by building layer by layer successfully until the entire physical object is complete. It is as simple as printing 2D on a sheet of paper, but in 3D it includes the third one Z-axis.
Each and every layer is thinly sliced & horizontal cross section of the object. You just imagine the baker makes the cake layer by layer till the entire cake is ready. 3D printing is also similar to baking but with bit more conscious. The 3D Printer needs a set of instructions from the computer to perform the process. In order to create a physical model it requires computer aided design software. The virtual designs are made using CAD file by using 3 dimensional modeling programs or by using 3D scanner. The created file is sent to the three dimensional printer and along the way, the software slices the design model into thousands or hundreds of horizontal layers. Hence these layers are printed layer by layer that is printed along the way top until the object is complete.
Many manufactures used printers in long for the design process to develop or create prototype in traditional manufacturing. But last few years printers have become expensive & slow. What is 3D printing? It is the process of making 3D solid object from a file. 3D printers are industrial robots. Now with the introduction of fast 3D printers the expense is moreover affordable (thousands of dollars) only and it saves many companies in investing the amount in prototyping process. Nowadays NIKE Company use 3D printers to create variety of colored prototypes of chapels & shoes. Before some years they used to spend more money and time on a prototype. Now due to less cost of 3D printers they can change the designs instantly on the computer and prototype can be printed on the same day.
Some manufacturing company’s uses 3D printers for custom or short run where the printed physical objects are not prototype but original end user products. Suppose if any part of your washing machine got repair. Now you would order the damaged part from the repairman. He usually gets it from a distributor who purchase those things shipped from China. They may mass-produce hundreds or thousands at once which are developed from an expensive mold. Hence in future this kind of situation will completely be reduced or stopped. In future everyone may use 3D printers at home who can print right part from a downloaded CAD file or can able to print at nearby printer shops.
3D printing is a process of producing a three-dimensional object by placing many layers of a material one over the other. This form of printing is carried out under computer control.3D printing is otherwise known as three-dimensional printing. Three-dimensional objects can be created in any shape or structure and of any material. The source is basically from a 3D model or a digital model. 3D is entirely different from all other types of printing. In this process, powdered form of any material is applied over 3D inkjet printers.3D printing technology is used in industrial, commercial and many other applications. This technique is quite complex from 2D type of printing. A digital design is achieved using this 3D printing. 3D printing is supported by a 3D modeling software. This printing is said to be an additive manufacturing process. There are various types of three dimensional printing.
Three-dimensional printing is useful for making new products and technologies. It’s easy to operate the printer and anyone can operate it without any difficulty. But the cost of 3D printers is high and the software cannot be bought at affordable rates. It may take many numbers of days or months to print the 3D object. There are some printers available for personal use that is of medium cost.3D printers are designed in such a way that the people without any knowledge of printers can also use. This is in contrast to traditional method of printing. This printer is connected to the computer and operated with the help of 3D software. The software is helpful in creating 3D digital model. The model formed is sliced into layers. It is converted into a design that can be read by the printers.
There are various 3D printing technologies. Each printer varies from the other in printing different materials. Various materials like plastics, metals etc are used. Printers will process layer by layer and build a defined shape. Stereo lithography was the first 3D printing process and it was for commercial use. This method gives the exact result and end product will be complete. It works with the help of laser light. Digital light processing is another technique like lithography but it uses photopolymers for its operation.
3D printing is an advanced technology for manufacturing any parts and is different from the other manufacturing techniques that are present today. The objects can be created with perfect size and shape with interesting features at a reasonable price. Tools are not employed in this process, so it makes the job easier. It uses standard and quality materials for the product to give a long operating life. For the people who are still confused on what is 3D printing, the simple answer is, it’s the process of creating an object with layers.3D printing can make even complex designs simpler. With the advent of this technology, the whole world utilizes its use to make wonders happen. Definitely 3D printers are a boon to the industrialists and all others. If we have given new great things to the world, all the credit goes to this wonderful machine called 3D printer.
3D printing is an amazing technology which involves the process of making 3D solid object from a file (digital). The physical objects are created by using additive processes. It involves an object is created by placing down the successive material layers. Each layer is seen as slice thinned horizontal cross section of the physical object. How 3D Printing Works? At first you have to make a virtual design of the object that you want to create. The virtual designs are made using Computer Aided Design (CAD) modeling software such as Sketchup, Solidworks, 123D Design and Blender or by using 3D scanner. This 3D scanner will scan the object to make a digital copy. For generating 3D models, 3D scanners utilize different technologies such as volumetric scanning, structured or modulated light, time of flight and many more.
Nowadays many big IT companies like Google and Microsoft made their hardware to workout 3D scanning. Microsoft’s kinect is a good example. Hence in future we can expect smart phones with inclusion of this 3D scanning technology. Digitizing or scanning the real physical objects into 3D models will become easier than capturing pictures. 3D professional scanners are very expensive. When you decide to print the digital file for 3D printing the modeling 3D software slices out the object model into thousands of horizontal layers. On uploading the sliced file in 3D printer the physical object is created layer by layer. The 3D printer reads out each and every slice and creates a physical object by blending the layers hardly to stick together.
3D printer is an amazing technology where a real object is created through single process and has lot of benefits. It incredibly reduces time, money and man power. The 3D printer utilized by lot of manufacturing companies gives an efficient lifetime unbreakable products. The are various 3D printing technologies that exist today. They are Fused Deposition Modeling, Stereolithography, Selective Laser Sintering and more.
Fused Deposition Modeling (FDM)
In Fused Deposition Modeling (FDM) technology, a hot thermoplastic material is pushed from a temperature controlled print to produce real object with high accuracy to original 3D model. In this method, the object is split into two sections. The plastic is heated and melted and the liquid form plastic is squeezed through into the nozzle which extrudes into the required section of the object. Once a layer is laid, it is cooled and hardened and then the next layer is deposited. The set up is simple and easy to handle. The products produced with this technique and materials have good physical and chemical properties.
Stereolithography (SLA) was the first technology that was practiced in 3D printing. This technique is based on liquid printing and was used in 3D printers for commercial purposes. The idea behind this technology is to be appreciated as it produces a well-defined 3D object. Stereo lithography was the only technology that was practiced in earlier days. After the advent of 3D printing technologies, this technology began to subside slightly. But it still used for many applications. In this method, the material is a liquid. This liquid material is converted into solid object with the help of a machine.
First, the CAD software processes the design or model and produces a file format that has description about the 3d object. The machine spreads the liquid and deposits a layer with the help of laser light. Once the layer becomes hard, the printer holds down for few seconds and starts printing the next layer. After the printing is done, the object is washed with a solution and placed in a UV furnace for the final finish. The printers need a design format and it must be understandable by them. STL is the format that Stereo lithography use for 3d object printing. This format contains all the information about the object such as size, shape, structure, geometry, measurements etc. The quality of the finished object depends on the type of SLA used.
Other 3D Printing Technologies
In Selective Laser Sintering (SLS) 3D printing technology type an object is built by using laser to fuse together the successive layers of a mixer of other powdered substances like metal, ceramic, wax, nylon or other materials.
3D printing is a process that includes all the technologies for creating a three-dimensional object. Each technology uses a material. The materials for the technologies differ one from the other. The similarity between various technologies is that a computer is needed for all the methods and software is required to create a model or design for an object. The materials for these technologies can be plastic, metal, nylon etc.

The products are made out of 3D printing with different levels of success. The paper is easily available and less cost materials used in 3D printers. The objects created using paper are environmentally safe & friendly, recyclable and do not need post processing.
Filament form is widely used as the material in fused deposition modeling (FDM) process. Due to the properties of flexible, durable and strong ability of this plastic material it is reliable for 3D printing as well as the colour option. Colour can also be added during post printing. ABS is commonly used plastic and used in filament form in FDM 3D printers. This kind of plastic is strong and come in variety of colours. From lot of non proprietary source this plastic material can be bring in filament form. Thus it is popular. PLA are used in filament format for FDM process and resin form for SL/DSL processes. This plastic is bio degradable and comes in different colors including transparent. This has been useful for many applications of 3D printing.
Plastics are strong materials that are used in 3D printing. Nylon is a white colored plastic material known for its high strength, low weight, good quality and durability. They are flexible and have a long life that can be used over a wide range of period. It is used alone as a raw material in the form of powder and even can be combined with other materials to produce another raw material for creating three-dimensional object. Nylon is also used as filaments in 3D printing technologies.
