3D Printing Essay

Good Essays
Imagine being able to create almost anything displayed on our computer screen. Imagine having able to take any 2 dimensional images and create a 3 dimensional object. The only thing that limits us is our creativity. Well 3D printing allows just that! Invented by a man named Chuck Hall, 3D printing allows us to take a digital file from a computer and “print” a real life physical 3 dimensional object.

So how does 3D printing work? A 3D printed object is built up one layer at a time from bottom-upwards by repeatedly printing over the same cross-sectional area. After that these layers are arranged on top of each other and as a result forming a solid 3 dimensional object. 3D printers work automatically by reading digital files from the computer called CAD (Computer Aided Design) files. These files are created using a 3D modeling program in the computer. Like every printer it has to use some form of ink. However, a 3D printer works slightly differently as it uses various materials such as polymers, plastic and maybe even metals as “ink” to print the object.

Now u may be thinking what are 3D printers used for, and more importantly how do they contribute to better healthcare? Well having the ability to print almost anything, Andreas Herrmann of the University of Groningen in the Netherlands and his colleagues are researching on

This is because further tests has to be done as the team only left the samples in the saliva and bacterial mix for only 6 days. “For clinical usage we need to extend this, and investigate the compatibility with toothpaste,” says Herrmann. Moreover the process of 3D printing is very long which is about 1 hour since teeth have a high degree of detail. Also, the team needed to make sure that the plastic is strong and rigid enough to be used as a

    When you or someone can recreate your idea into a 3d image called a CAD (Computer-aided Design) file. From the CAD file, it’s converted to a STL (Standard Tessellation Language) file. Then it’s transferred over to a 3d printer, which can print your idea in many different ways depending on what type of 3d printer is being used. There is a very diverse selection for types of additive manufacturing. Several different materials you can print with exist too, and more materials are getting the road paved for them to be printed as well.…

    The second step would be converting the CAD drawing into STL format or standard tessellation language. This is the file format that was created for 3D printing way back in 1987 used by a sterolithography apparatus machine but has been modified for the 3D printers of today. The third step on the digital side of the process is to transfer the STL file to the AM machine. This is where you manipulate these size and angles and dimensions of the object you are about to…

    Today, AM is used to create end-products used in many different applications, from aerospace, automotive and even biomedical prosthetics. AM can create highly customizable products, and it’s this advantage that is being exploited in today’s world of manufacturing. 3D printing and AM are almost interchangeable. AM is the broader term, encompassing processes such as Rapid Prototyping (RP) which focused on creating preproduction visualization models, but the models weren’t actually used in the end product. Rapid Tooling (RT) the production of tooling to be used in another process like cores, patterns, or jigs.…

    This research’s problem statement investigates the ability to connect a 3D printed model to the 3D printer used for its production. The main objective focused on identification of physical characteristics of the 3D printed model that are caused by a specific 3D printer parameter. Two 3D printers were utilized in this research. The first is a Printrbot 3D printer (model 1404) running Marlin Firmware (version: 1.0.0 bedlevel metal- simple). The software used to communicate with the Printrbot 3D printer is Repetier-Host (version 0.56) running on a Macbook Pro.…

    Few examples are Cinema 4D, 3D MAX and Maya. For complex objects like characters, we can import reference images into the 3D space and use these images as a guide to model the object to their correct scale and proportion. For less complex objects, we can just use the basic object shapes available or the different kind of spline tool and adjust the points/edge/polygons respectively. A few other tools also available are subdivision surface (we can use to round up regular cube shapes) and deformer tools like bending, twisting, shearing, etc. Texturing Once all the modelling for objects, characters, and environment is completed, we can add in appropriate materials and textures created in the same software to enhance the models.…

    Then those photographs are combined and sped up. Computer Generated animation is when an animator uses computer software to animate. The computer generated animations can be rendered in either 2D or 3D. The 2D animation is very similar to the traditional method of animating, however for the 3D animation the animator has to model each character and object. The Role of Animation in the Digital Media…

    The first method is called Stereolithography (SLA). [6] This method starts by creating a 3D model on a computer with precise information of each layer. This information is then transferred to a printer. Liquid resin is then exposed to ultra-violet light to create the product layer by layer. After the whole process is finished, the finished product is rinsed in solvent and cleaned.…

    Resulting data was a highly accurate representation of the superficial topographic features of the bone the initial 3-D data set contained eighty thousand facets. The second step was generating a 3-D model of the femur. The model was made to be manipulated digitally. The 3-D digital data was transferred to the UT Aerospace Engineering/ Engineering Mechanics Learning Resource Center to be digitally processed. The original 3-D digital model was too complex to manufacture using the laser sintering machine available at UT so they had to change it to be more simple.…

    We us mechanical engineering to design and make things maybe like the shell of the computer. According to Columbia engineering “mechanical engineering is a diverse subject that derives its breadth from the need to design and manufacture everything from small individual parts and devices to large systems spacecraft and machine tools.” Mechanical engineers are suppose to make item and sells it on the market. Not only that they have to design the parts for it they must also find a way to make the product and without failing any part. Mechanical engineers have a role in almost anything from big thing to tiny thing like from a car to an electric component. While said Mechanical engineering can design parts for everything from frames of a computer to electronic parts of a computer.…
