“…In contrast, design rules deal with a more specific aspect of identifying the limitations of AM, serving as design code. Abundant research can be found in this area [15,[55][56][57][58][59][60]. Research on design rules can be divided into two groups: experimental method, for example benchmark study, and systematic method.…”

“…Then, after studying the attribute value, boundary conditions of these groups, design rules are obtained. Design rules in systematic method was also reported by Popsecu for rapid prototyping (RP) [56] and Kruf et al for RM [57]. In addition, ASTM released a general design guidelines [61] for AM including design opportunities and limitations.…”

As additive manufacturing (AM) process evolves from rapid prototyping to the end-of-use product manufacturing process, manufacturing constraints have largely been alleviated and design freedom has been significantly broadened, including shape complexity, material complexity, hierarchical complexity, and functional complexity. Inevitably, conventional Design Theory and Methodology (DTM) especially life-cycle objectives oriented ones are challenged. In this paper, firstly, the impact of AM on conventional DTM is analyzed in terms of design for manufacturing (DFM), design for assembly (DFA), and design for performance (DFP). Abundance of evidences indicate that conventional DTM is not qualified to embrace these new opportunities and consequently underline the need for a set of design principles for AM to achieve a better design. Secondly, design methods related with AM are reviewed and classified into three main groups, including design guidelines, modified DTM for AM, and design for additive manufacturing (DFAM). The principles and representative design methods in each category are studied comprehensively with respect to benefits and drawbacks. A new design method partially overcoming these drawbacks by integrating function integration and structure optimization to realize less part count and better performance is discussed. Design tools as a necessary part for supporting design are also studied. In the meantime, the review also identified the possible areas for future research.

“…Recently, a steerable laparoscopic instrument prototype, DragonFlex ( Figure 1) (6), was designed at TU Delft and made by additive manufacturing (9)(10)(11)(12)(13) at 5mm width from a ceramic-filled epoxy resin, which is one of the most precise and accurate materials available for stereolithography. Being the world's first additive manufactured steerable laparoscopic instrument prototype, it is composed of only seven structurally rigid components and two looped steering cables.…”

The experimental results proved that the optimised rolling joint curvature significantly minimises play, thus being a major improvement compared to the original design. The optimised rolling joint was implemented in a new real-scale DragonFlex prototype. The presented optimisation method enables elimination of a conventionally used cable tensioning device and it is generally applicable to steerable minimally invasive instruments that use a rolling joint.
