Multi-material microstereolithography
The International Journal of Advanced Manufacturing Technology, 2009We have previously described the development of a microstereolithography (µSL) system using a Digital Micromirror Device (DMD) for dynamic pattern generation and an ultraviolet (UV) lamp filtered at 365 nm for crosslinking a photoreactive polymer solution.

Material efficiency in a multi-material world
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013Material efficiency—using less of a material to make a product or supply a service—is gaining attention as a means for accomplishing important environmental goals. The ultimate goal of material efficiency is not to use less physical material but to reduce the impacts associated with its use.

Development of multi-material 3D printer
Nano-, Bio-, Info-Tech Sensors, and 3D Systems II, 2018The aim of developing a multi-material 3D printer is to print an object with a different kind of soft and hard material in a single run. It is expected that the combination of printing soft and hard material will be a new kind of 3D printer. The main printing material for this printer is the conductive based soft filament made by our laboratory ...

Multi-material adaptive volume remesher
Computers & Graphics, 2016We propose a practical iterative remeshing algorithm for multi-material tetrahedral meshes which is solely based on simple local topological operations, such as edge collapse, flip, split and vertex smoothing. To do so, we exploit an intermediate implicit feature complex which reconstructs piecewise smooth multi-material boundaries made of surface ...

A multi-material virtual prototyping system
Computer-Aided Design, 2005Abstract This paper proposes a multi-material virtual prototyping system for digital fabrication of heterogeneous prototypes. It consists mainly of a topological hierarchy-sorting algorithm for processing slice contours, and a virtual simulation system for visualisation and optimisation of multi-material layered manufacturing (MMLM) processes.

Anisotropic Elasticity and Multi-Material Singularities
Journal of Elasticity, 2001Abstract Multi-material wedges associated with convergence of geometrical and material discontinuity generally show singular stress fields. Under a temperature load, the different sectors of the wedge experience incompatible thermal expansions.

Development of a multi-material micropump
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2006In this paper, the design of a multi-material micropump will be described. The micropump inhibits a very simple design and therefore is very cost efficient. The pump consists of one plastic part, one metal diaphragm, and three piezo lead-zirconate titanate (PZT) ceramics.

Communications in Computational Physics
Summary: This work is devoted to the numerical approximation of three-temperature multi-material hydrodynamics. Such systems are subject to stiff phenomena which require specific care during the discretization. In particular, the so-called discrete equation method is here applied to the radiation transport, in the optically-thick limit.

Machining technologies for multi-materials
2015The weight reduction in the automobile industries is one of the major motivations for the implementation of lightweight construction materials. Today, these materials have become an essential component, not only for luxury class cars, but also for mid-size and compact cars.

Challenges in Drilling of Multi-Materials
Materials Science Forum, 2013Drilling of multimaterails is a challenge to manufacturing engineers. Many combinations of multimaterial stacks are possible, they are CFRP/Ti, CFRP/Al, CFRP/Ti/Al etc. The thrust force and surface roughness measured during drilling using plain carbide drill (K20) with drill parameters in drilling carbon fibre reinforced plastic (CFRP) laminate ...
