Mechanical Engineering

Describe two examples of automation technology that contributedto the development of additive manufacturing and why additivemanufacturing would not be possible without that technology.
Design for X (DFX) is a design philosophy that emphasizes asingle characteristic of a new product that will guide all of thedecisions in the design of that object. What makes this a powerfulstrategy?
Describe two characteristics that assist with successful 3Dprinting that should be present in an object designed using DesignFor Additive Manufacturing (DFAM) as a guiding philosophy? (forexample: having one large flat side that can adhere to a buildplate)
Of the following: Design for Cost, Design for Reliability, orDesign for Manufacturability, which is most compatible withproduction by additive manufacturing. Which characteristics ofadditive manufacturing contribute to that compatibility? why?

A Computeraided design technology Additive Manufacturing technology primarily makes use of the output from mechanical engineering 3D Solid Modeling CAD software It is important to understand that this is only a branch of a much larger set of CAD systems and therefore not all CAD systems will produce output suitable for layerbased AM technology Currently AM technology focuses on reproducing geometric form and so the better CAD systems to use are those that produce such forms in the most precise and effective way Early CAD systems were extremely limited by the display technology The first display systems had little or no capacity to produce anything other than alphanumeric text output Some early computers had specialized graphics output devices that displayed graphics separate from the text commands used to drive them Even so the geometric forms were shown primarily in a vector form displaying wireframe output As well as the heavy demand on the computing power required to display the graphics for such systems this was because most displays were monochrome making it very difficult to show 3D geometric forms on screen without lighting and shading effects Laser Many of the earliest AM systems were based on laser technology The reasons are that lasers provide a high intensity and highly collimated beam of energy that can be moved very quickly in a controlled manner with the use of directional mirrors Since AM requires the material in each layer to be solidified or joined in a selective manner lasers are ideal candidates for use provided the laser energy is compatible with the material transformation mechanisms There are two kinds of laser processing used in AM curing and heating With photopolymer resins the requirement is for laser energy of See Answer
