3D Printing vs. CNC Machining of Plastic Parts

The process of 3D Printing, also known as additive manufacturing, has now been developed for several materials including plastic and metal. This article will focus on 3D printing compared to CNC machining of plastic parts.
 
The 3D Printing process is an additive process during which layers of molten plastic are added until the part is completely formed.  These layers can often be noticed, and this can be an aesthetic issue. In evaluating whether or not this is the right approach the two key questions to be answered are:
1) What is the application?Read more
