Abstract: Additive manufacturing (AM) or 3D printing is a new and exciting way to make parts. However, traditional manufacturing rules do not always apply when designing for AM. Both beginners and professionals can benefit from understanding how to make this technology work for them. Here you will learn the four ways you can design or redesign your parts for AM in order to maximize their potential. Supports / Overhangs Each technology deals with this differently. Generally, there is a critical angle (typically 45 degrees) that allows no support to be needed such as in the letter Y. Some need supports for all bridges of a certain length such as the middle of a capital H. Others need supports for overhangs such as at the ends of a capital T. How supports are designed or generated and removed needs to be thought of in the design process. Orientation Two factors come into play for orientation. First is material properties can differ depending on the direction they are built. This shows some test bars I printed to test how build orientation affects the electrical resistivity of a metal alloy. Strength can differ depending on build orientation so if you have a part that needs to have a certain strength in a certain direction, you will need to know how the orientation affects the strength of the part. The second is that printed features can come out looking differently depending on orientation. If you have a circle you want to print and have it come out circular, you will need to orient the part so that the circle is in the XY plane and not chopped up by the layers. Minimum feature size / Resolution This greatly depends on the process you use, and especially the machine you use. Just because two machines from different manufacturers use the same technology, they may not have the same feature specifications. There are also many factors that play into minimum features, and each are different. Here you can see some of the minimum sizes for a typical SLS process in Nylon. This is where you need to find out the machine and material specific specifications if you want to be designing features in the sub millimeter range. Post Processing There are many different ways post processing can affect how you design. If the process relies on supports, they will need to be removed manually, or potentially semi-automatically. If attached to a build plate, the parts will need to be removed. If there is excess powder or liquid trapped, it will need to be removed. If you want uniform or enhanced material properties, a heat treatment or post infusing of a secondary material may be needed. If you have critical surfaces that assemble, post machining will be required including custom part holding jigs or fixtures. All of these need to be taken into consideration when designing in order to gain the greatest benefits from AM. Method 1: Send directly for AM Method 2: Modify for AM Method 3: Combine and redesign for AM Method 4: Rethink and redesign for AM]]>
