3. What is 3D Printing 3D printing or additive manufacturing is a process of making three dimensional objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object. There is one exception though, and it’s called volumetric 3D printing. With volumetric printing entire structures can be formed at once without the need for layer-by-layer fabrication. It’s worth noting, however, that as of now, volumetric technology is primarily in the research phase. 3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a block of material with for instance a milling machine. 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.

5. Modeling Additive manufacturing takes virtual blueprints from computer aided design (CAD) animation modeling software and “slices” them into digital cross-sections for the machine to successively use as guidance for printing.

6. Printing To perform a print, the machine reads the design and lays down successively layers of liquid, powders,or sheet material to build the model from a series of cross sections. These layers, which correspond to the virtual cross section from the CAD model, are joined together or automatically fused to create the final shape. The primary advantages of this technique is its ability to create almost any or geometric feature.

7. Finishing Through the printer products resolution is sufficient for many applications, printing a slightly oversized version of the desired object in standard resolution and then removing material with a higher-resolution substractive process can achieve great precision. Supports are removable or dissoloable completion of the print, and are used support overthanging features during construction.

8. How does it work? First, a virtual design of the object is made. This design will work like a blueprint for the 3D printer to read. The virtual design is made using computer-aided design (CAD) software, a type of software that can create precise drawings and technical illustrations. A virtual design can also be made using a 3D scanner, which creates a copy of an existing object by basically taking pictures of it from different angles. CAD software creating a 3D model- Once the virtual model is made, it must be prepared for printing. This is done by breaking down the model into many layers using a process called slicing. Slicing takes the model and slices it into hundreds or even thousands of thin, horizontal layers using special software. Slicing the 3D model- After the model has been sliced, the slices are ready to be uploaded to the 3D printer. This is done using a USB cable or Wi-Fi connection to move the sliced model from the computer it’s on to the 3D printer. When the file is uploaded to the 3D printer, it reads every slice of the model and prints it layer by layer.

9. Basics of 3D Printer Design Structure The design of a 3D printer typically includes a frame, axes, and a build platform. Extruder This component is responsible for melting and depositing the material layer by layer to create the object. Motion system It comprises the motors and belts that move the print head and the build platform.

10. COMPONENT OF 3D PRINTER Extruder - The extruder is one of the most important component of the 3D printer. It holds the filament in place and control the amount that is fed into the hot end. Print bed- Is the part on which the 3D printed object rests . Filament - The most important component of the 3D printing process is the filament. It is the raw material required for printing three dimensional objects. Stepper motor- These are what determine the mechanical movement of overall printer. Hotend - The hot end is where the filament is melted and then extruded through the nozzle.

11. Controller Board- Controller board is also called the motherboard or mainboard of 3D printer because it sends out commands to all the parts. Heatbreak - The goal of heatbreak is to allow as much heat transfer as possible within the hot side to melt the filament. Belts - The second motion components of a 3D printer is the set of belts present inside it. The stepper motor connects to drive gear via belts which fit over the gears and allow them to moves smoothly with the motor. Threded rods- Threded rods allow the 3D printer had to move up and down in the z-direction & belts allow movement in the x and y axis.

12. Future Aspects 3D printing is also helpful in producing architectural scale models. It is even beings explored as a solution for constructing extraterrestrial habitates on the Moon or Mars, should the need ever arise.

13. Challenges Facing 3D pRINTING Intellectual property rights of the 3D printing users. Nearby anything can be printed by 3D printers and this is a troubling prospect if criminals use 3D printers to create illegal product.

14. Conclusion Nothing communicate ideas faster than a three-dimensional part or model. With a 3D printer you can bring CAD files and design ideas to life- light from the desktop. Test from, fit and function – and as many design variation as you like- with functional parts.
