Fused deposition modeling

The filament actually gives off a burning wood aroma, and your end product acts almost identical to the way wood would. You can sand, stain, and grind it in any way you’d prefer. -Define technical terms and provide necessary background information. “Hence, in 2010, the American Society for Testing and Materials (ASTM) group “ASTM F42 – Additive Manufacturing”, formulated a set of standards that classify the range of Additive Manufacturing processes into 7 categories (Standard Terminology for Additive Manufacturing Technologies, 2012).” Vat photopolymerisation, Material Jetting, Binder Jetting, Material Extrusion, Powder Bed Fusion, Sheet Lamination, and Direct Energy Deposition Other key terms in 3d printing, or additive manufacturing are; SLA- Stereolithography Apparatus FDM- Fused deposition modeling DLA- SLS- Selective laser sintering SLP- AM- Additive manufacturing -Provide examples of use (if appropriate). Additive manufacturing brings us the era of printing houses or cars. Creating new, completely identical limbs from DNA for amputees. Comparisons Compare to similar products and/or technologies addressing similar needs: -Costs -Performance -Capabilities and limitations Recommendations State the conditions under which the product/technology should be used and/or chosen overcompeting alternatives. Be as definite and explicit as possible.…

that the machine can interpret and recreate the data. There are different formats used, but a common one is Standard Tessellation Language (STL). An STL file is created for each layer. There can be several layers per millimeter. The machine then creates a model layer-by-layer using one of several different methods. There are an incredible amount of different processes which can be more easily classified by the nature of material deposition. They fall into any one of the following:…

Both 3D printers follow the Fused Deposition Modeling (FDM) process. The Printrbot 1404 is capable of printing both Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA) plastics on a heated printed bed. The Printrbot extruder is able to move on the x, y, and z axis, while its print bed is limited to x axis movements. The Voxel8 is also capable of printing both ABS and PLA plastics with the addition of a conductive silver material. The Voxel8 also includes a heated print bed. The…

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. This method is the oldest technique in the 3D printing history. The second method is called Fused Deposition Modeling…

The two main types of 3D printing are FDM and SLA. FDM stands for Fused Deposition Modeling, in FDM a thermoplastic resin, usually in the form of a wire (Figure 7), is fed through a hot extruder in turn heating the plastic allowing it to become formable. As the plastic is heated it is precisely placed by the printer head. The melted plastic is placed layer by layer to create a detailed model. There are also SLA printers. SLA stands for stereo lithography. Similar to FDM, SLA uses an additive…

renders generalized claims that 3D printing is more energy efficient incorrect; 'A 2011 study measured the electricity use per kilogram of material deposited using several different 3-D printing methods and found that some printers used up to 80 times more energy than others. ' (Olson, 2013). Furthermore even machines that are actually proven to be more energy efficient than other manufacturing methods are only advantageous up to a certain manufacturing volume. Material waste is an area of 3D…

The Big Three Choosing one of the Big Three for a project can be a very difficult task, but hopefully after reading this you will have a better understanding of when to use which. There are many differences between the Big Three. Firstly, they are all part of Adobe Creative Suite and they are: Photoshop, Illustrator, and InDesign. Photoshop, an iconic program of Adobe Creative Suite, is used most effectively to retouch and crop photos. This program can be used in a variety of ways to…

deposited from the middle Cambrian to the late Cambrian; however, depositional environments were varied throughout the depositional history of the Wilberns formation (Barnes and Bell, 1977). The Paleogeographic map of North America (fig. 5) from Blakely (2005) demonstrates that the Llano region of central Texas was submerged in a shallow sea, this map is an approximation, especially given that aeolian sedimentary phenomena, like calcrete (Read, in Walter, 1976, p. 56; Deso, 1998, p. 49), and…

uncorroborated. Mr. Johnson served as Mr. Barry’s direct supervisor for approximately four years, but he could not describe Mr. Barry’s construction experience, his exposure to facilities related organizations, facilities experiences, space procurement expertise, his interactions with the General Services Administration (GSA), or any internal departments with the Department of Veterans Affairs. Yet Mr. Johnson and Mr. Sanderson scored Mr. Barry’s resume the highest score of the candidates, a…

On Monday, July 10th, I worked from 9:30 a.m. to 5:30 p.m. On this day, I watched a four-hour deposition. A deposition is when a witness gives testimony under oath. This particular deposition was for a case in which a motorcyclist was hit by a car. The motorcyclist is the plaintiff in the case (which is the person being represented by the firm) and sustained serious injuries after the accident. The person who was being deposed witnessed the accident. The deposition started at 10:00 a.m. and…
