Design rules for FFF
This page presents basic design rules for FFF by specific process parameters. Table 1 shows the basic design rules for FFF.
Figures 1-2 are from a design catalog developed by G. A. O. Adam and D. Zimmer [6], which provides recommendations regarding element transitions, aggregate structure, and process limits.
Along the same lines, Figures 3-4 [7] guide the walls, printed cylinders, and bores and their process limits.
On the other hand, design cards have been developed for additive manufacturing [8]-[9], that consider aspects such as Process Capabilities, Manufacturability Improvements, Best Known Design Practices, and Design Process Improvements. The following are the design cards (source [8]).
AM Principle Cards
In addition, J. W. Booth et al. [10] developed a worksheet to tell whether a part is manufactured by additive or conventional manufacturing. The worksheet, presented in Figure 5 below, serves as design guidelines or rules.
It is recommended that the information in the medical, process chain, and fault theory case pages be used to push the natural limits of the FFF process to take advantage of its virtues [3]-[5].
