Design for manufacturability
Now that we have our printed part, let's investigate how we can make it better. We're going to be exploring two ways to improve our design. First, look for places where we want to improve the 3D model for a better look and feel. Adding more subtle curves and fixing any modeling mistakes. Then, adjusting our design to take advantage of 3D printing technology. Our original part was made by injection molding. If you look closely at the part you'll notice that it's hollowed out. This reduces the amount of material needed and reduces the cost of the part. You can also imagine how the rounded corners would slip easily out of a two part mold. This part was made with the manufacturing method of injection modeling in mind. This method of designing is called design for manufacturability and it's an important concept when we're designing parts to be fabricated. You make design decisions to make the part faster, easier, and cheaper to produce. In our case, we are copying an injection molded part…
