3D Printed Prosthetics

3D Printers:
The intended purpose of a 3D printer is to print three dimensional objects such as cookware, prosthetics, clothing, and cars, using a one of three main methods. The methods are: stereolithography (SLA), fused deposition modeling (FDM), selective laser sintering (SLS). Uses for printed objects can include but are not limited to: prototyping, metal casting, architecture, education, healthcare, and entertainment/retail.
How It Works:
A CAD file is made using a 3D modeling program. The file is then uploaded into a printer. Printers using the stereolithography (SLA) method to print focus a concentrated beam of light onto the surface of the resin. The printer then draws each layer of the object, hardens it, and bonds it to the below layer. Printers using the fused deposition modeling (FDM) method to print heat the extruding beads of molten thermoplastic material then layering them. Printers using the selective laser sintering (SLS) method to print are similar to the SLA method printers but it uses powdered materials.
The Role of Computing:
3D models are created using a CPA (Computer Aided Design) file. These CPA files are created using a 3D modeling program, for new objects, or a 3D scanner, for preexisting objects. To prepare the final 3D model created in a 3D modeling program for printing the software slices the model into thousands of horizontal layers. When the file is uploaded into the 3d printer, the printer creates the object layer by layer. Every slice is read and printed by the 3D printer. The layers are of the object are blended together resulting in on 3D object.
Relationship Between the Data and the Product:
From the CPA (Computer Aided Design) file is used to instruct how to print the three dimensional object. There are currently websites for the average 3D printer user to download CPA (Computer Aided Design) files to be used at their home, as the technology for 3D printers becomes cheaper and easier to use more of these
