“…First, additive manufacture has been considered to be a new output device for computergenerated designs [McMains et al 2005]. A variety of novel design processes have targeted 3D printed output: from computergenerated sculptures [Xin et al 2011;Mitra and Pauly 2009], through 3D puzzles [Lo et al 2009;Xin et al 2011] to scientific visualizations [Bailey 2005]. Second, computer graphics techniques have been employed in developing novel additive manufacturing processes such as deformable objects [Bickel et al 2010].…”

Figure 1: Starting from a 3D mesh (left), our system allows to intuitively add 3D-printable joints (center) that, when 3D-printed, create a functional, posable model with joints that exhibit internal friction. The model leaves the printer ready to use; no manual assembly is required. AbstractAdditive manufacturing (3D printing) is commonly used to produce physical models for a wide variety of applications, from archaeology to design. While static models are directly supported, it is desirable to also be able to print models with functional articulations, such as a hand with joints and knuckles, without the need for manual assembly of joint components. Apart from having to address limitations inherent to the printing process, this poses a particular challenge for articulated models that should be posable: to allow the model to hold a pose, joints need to exhibit internal friction to withstand gravity, without their parts fusing during 3D printing. This has not been possible with previous printable joint designs. In this paper, we propose a method for converting 3D models into printable, functional, non-assembly models with internal friction. To this end, we have designed an intuitive workflow that takes an appropriately rigged 3D model, automatically fits novel 3D-printable and posable joints, and provides an interface for specifying rotational constraints. We show a number of results for different articulated models, demonstrating the effectiveness of our method.

Field-aligned mesh joinery

Mesh joinery is an innovative method to produce illustrative shape approximations suitable for fabrication. Mesh joinery is capable of producing complex fabricable structures in an efficient and visually pleasing manner. We represent an input geometry as a set of planar pieces arranged to compose a rigid structure, by exploiting an efficient slit mechanism. Since slices are planar, to fabricate them a standard 2D cutting system is enough. We automatically arrange slices according to a smooth cross field defined over the surface. Cross fields allow to represent global features that characterize the appearance of the shape. Slice placement conforms to specific manufacturing constraints.

“…Optimizing construction sequences. Constructability has been investigated in the context of 3D puzzles [Lo et al 2009;Xin et al 2011;Song et al 2012], 3D assembly instructions [Agrawala et al Figure 4: Our algorithm converts an input masonry model in a work-minimizing construction sequence.

Figure 1: We propose a construction method for self-supporting structures that uses chains, instead of a dense formwork, to support the blocks during the intermediate construction stages. Our algorithm finds a work-minimizing sequence that guides the construction of the structure, indicating which chains are necessary to guarantee stability at each step. From left to right: a self-supporting structure, an intermediate construction stage with dense formwork, an intermediate construction stage with our method and the assembled model.
