The Future

Additive Manufacturing (AM) is the digital manufacturing technology by which products are fabricated directly from computer models by selectively curing, depositing or consolidating materials in successive layers. The technology has provided an opportunity to rethink the methods of product design to maximize the product performance through the synthesis of material compositions, structure, and sizes. This overview is created to relate the unique capabilities of AM technologies and discuss the methods of product design. Finally, the current problems and difficulties in this field are discussed in this paper, and this paper proposes the development direction of the product design for additive manufacturing in the future.

Net Shaping

Directly driven by CAD model, based on principle of discrete-superposition, rapid prototyping technology is the generic terms of rapid manufacturing 3-dimensional physical entities with any complex shape. One of its main development trends is direct rapid manufacturing for metal parts. Up to now, there are many methods utilizing laser beam containing selective laser melting, selective laser sintering and laser engineered net shaping. Research and development of these means for direct rapid metal manufacturing are presented in this paper. Digital direct rapid manufacturing for metal parts represents development direction of advanced manufacturing technology.

Pitch Curve

According to the meshing principle of non-circular gears, the meshing characteristic and digital manufacturing technology of Limacon type gears is studied. Based on analyzing the parameterized modeling of pitch curve, transmission characteristics and convexity-concavity analysis on Limacon type gears, the transmission feasibility of this type gear is proved. Through tooth shape design, CAM calculation and analysis with example, and processing simulation, the validity and manufacturability of theoretical design method on this type gear is proved. The research results can provide more systemic theory basis for the design, manufacture, measure and application of Limacon type gears.

This article addresses virtual and physical prototyping of some symmetrical patterns collected from the Ainu cultural heritage. The indigenous people living in the northern part of Japan (e.g., Hokkaido), known as Ainu, often decorate their houses, clothing, ornaments, utensils, and spiritual goods using some unique patterns. The patterns carry their identity as well as their sense of aesthetics. Nowadays, different kinds of souvenirs and cultural artifacts crafted with Ainu patterns are cherished by many individuals in Japan and abroad. Thus, the Ainu patterns carry both cultural and commercial significance. A great deal of craftsmanship is needed to produce the Ainu patterns precisely. There is a lack of human resources having such craftsmanship. It will remain the same in the foreseeable future. Thus, there is a pressing need to preserve such craftsmanship. Digital manufacturing technology can be used to preserve the Ainu pattern-making craftsmanship. From this perspective, this article presents a methodology to create both virtual and physical prototypes of Ainu patterns using digital manufacturing technology. In particular, a point cloud-based approach was adopted to model the patterns. A point cloud representing a pattern was then used to create a virtual prototype of the pattern in the form of a solid CAD model. The triangulation data of each solid CAD model were then used to run a 3D printer to produce a physical prototype (replica of the pattern). The virtual and physical prototypes of both basic (Hokkaido) Ainu motifs and some synthesized patterns were reproduced using the presented methodology. The findings of this study will help those who want to digitize the craftsmanship of culturally significant artifacts without using a 3D scanner or image processing.
