The deposition paths, or roads, used to create FDM parts area a critical factor in determining part performance. In some cases, such as the FDM machines discussed in this work, there are no designer options to control road patterning, making it a hidden constraint in the design process. Even if the option is given, the designer must be aware that it is a variable. In either case, deposition road patterning is not something that can be taken for granted when designing parts. A new level of DfFDM guideline development must be implemented if AM is to reach the level of universality as other traditional machining methods.
