MOCCA: Modeling and Optimizing Cone-joints for Complex Assemblies

We present a computational framework for modeling and optimizing rigid assemblies using cone joints. Cone joints are integral joints that generalize traditional single-direction joints such as mortise and tenon joints to support a general cone of …

State of the Art on Computational Design of Assemblies with Rigid Parts

An assembly refers to a collection of parts joined together to achieve a specific form and/or functionality. Designing assemblies is a non-trivial task as a slight local modification on a part’s geometry or its joining method could have a global …

Computational Assembly for Fabrication: Shape Optimization

Reusable support for additive manufacturing

Additive manufacturing (AM) processes such as material extrusion and vat photopolymerization all require supports to print parts with overhang features. These additional supports using the same or different materials are a waste of materials since …

Design and Structural Optimization of Topological Interlocking Assemblies

We study assemblies of convex rigid blocks regularly arranged to approximate a given freeform surface. Our designs rely solely on the geometric arrangement of blocks to form a stable assembly, neither requiring explicit connectors or complex joints, …

DESIA: A General Framework for Designing Interlocking Assemblies

Interlocking assemblies have a long history in the design of puzzles, furniture, architecture, and other complex geometric structures. The key defining property of interlocking assemblies is that all component parts are immobilized by their geometric …

Machined Sharp Edge Restoration For Triangle Mesh Workpiece Models Derived From Grid-Based Machining Simulation

Grid-based machining simulation methods have become very popular due to their advantages in computational efficiency. However, these methods are prone to generating machined workpiece models with chamfer edges, which reduce model accuracy and visual …

CofiFab: Coarse-to-Fine Fabrication of Large 3D Objects

This paper presents CofiFab, a coarse-to-fine 3D fabrication solution, combining 3D printing and 2D laser cutting for cost-effective fabrication of large objects at lower cost and higher speed. Our key approach is to first build coarse internal base …
