Computer-Aided Design for Additive Manufacturing

Daniel J. Epstein Department of Industrial and Systems Engineering

Yong Chen, Ph.D.
3D Systems Inc., Valencia, CAABSTRACTBased on layer-by-layer building process, additive manufacturing has some unique properties. It is purely digital and therefore very flexible. Additive manufacturing can deliver cost effective solutions especially for small amount productions and therefore holds the key to mass customization. More importantly, design with complex geometries has no additional manufacturing costs. This opens the possibility to consolidate components in an assembly and even enables a product design that is self-assembled during the manufacturing process. However, to fully explore the potentials of additive manufacturing, new design methods and tools need to be developed based on its properties.This talk presents my research on developing design methods and tools for two types of
additive manufacturing processes, direct and indirect (that is, using other traditional
manufacturing processes such as injection molding and investment casting to produce the final products). First, one of the indirect additive manufacturing processes, Rapid Tooling, is introduced. Two problems in its current usage are identified. Correspondingly a multi-piece mold design method based on computational geometry and a design-for-manufacturing method based on decision-based design are developed. The methods are employed in prototype systems and illustrated by an example. Then a truss structure generation system for direct additive manufacturing process is introduced. The biggest challenge in developing such a system is identified and addressed by developing a point-based method for offsetting polygonal models. The approach is general and robust with a tight error bound. Besides generating inner shells of a given polygonal model, the method can also be used in automatically adding rounds
and fillets in a design, simulating machining results for a path planning, and generating dimensional compensations for manufacturing processes.MONDAY, APRIL 11, 2005

"A Systematic Study of Molecular Electronics:
From Molecules to Electronic Switching Devices to Large Scale Nanowire Crossbar Circuits"Dr. Yi Luo
(California Institute of Technology)The field of molecular electronics, where molecules are used as active components in electronic circuits, provides promising approaches for building ultra-small, energy efficient, and very fast devices for memory and logic applications. In recent years, a substantial amount of interest has been drawn to this attractive and extremely interdisciplinary field.In this talk, I will present a comprehensive study of a molecular electronic system, including design, fabrication, and characterization of chemical materials, switching devices, and multifunctional circuits. A focal point of this research has been to integrate a series of bi-stable molecules into molecular switch tunnel junctions. We have successfully demonstrated electrical ON/OFF switching based on the chemical bi-stability of these molecules. Important issues in material preparation, device fabrication, and electrical characterization will be discussed. In addition, I will focus on scaling of these devices and crossbar circuits from micro-scale to nano-scale. The latest system contains 22.5Kbits at a density of 1011/cm2 (33 nm full pitch). I will also discuss a scheme in which multi-functional units, e.g. memory, logic, and sensing, can be integrated into a large scale nanowire crossbar array system.Location: Olin Hall of Engineering (OHE) - 100D, Studio F

Digitally Assisted Analog Circuit Design for Communication SoCs

DISTINGUISHED LECTURER SERIES"Digitally Assisted Analog Circuit Design for Communication SoCs"Prof. TERESA MENGStanford UniversityAbstract:The availability of high-speed network infrastructure and low-cost CMOS technology has dramatically changed the landscape of broadband communication in the past few years. To accommodate the ever increasing data rates, communication SoC design is no longer merely a circuit integration problem. The implementation of high-throughput communication SoCs with a power constraint requires a new design strategy for the embedded analog components. One solution is to exploit the computational capability of digital circuitry to continuously calibrate the mixed-signal and analog circuits and compensate for their ever more tenuous realization as technology is scaled and supply voltages are reduced. To support the computational requirements, digital processing architectures will be developed and implemented which have the efficiency of dedicated circuitry while allowing the flexibility to adapt to changing environments, algorithms, waveforms and circuit performance. In this talk, adaptive optimization techniques in combination with on-chip calibration will be applied to reducing the power consumption of an OFDM transmitter and a high-speed ADC. State-of-the-art developments in digitally assisted communication SoCs will be discussed, along with the opportunities for future innovations.Bio:Teresa H.

Nanophotonics for Communications and Medicine

"Nanophotonics for Communications and Medicine"Mehmet Fatih Yanik
(Stanford University, Applied Physics)Host: Prof. Won NamgoongAbstract:
The use of dynamic photonic bandgap nano-structures opens fascinating new possibilities for controlling the classical and quantum properties of light. The spectrum of light can be molded almost arbitrarily with small refractive index modulations, leading to unprecedented information processing capabilities on-chip. As examples of such capabilities, we show how light pulses can be coherently stopped, stored, and time-reversed with linear optics and modulators. Photonic bandgap nano-structures can confine photons to sub-micron scale volumes, which leads to ultra-strong enhancement of optical non-linearities. We discuss how such non-linearities can be used to make fast micron scale low-power photonic transistors and memories, with switching energies close to that of CMOS electronic circuits. We show how nano-scale all-optical devices can be systematically cascaded on-chip without optical isolators, even in the presence of reflections. The rest of the talk introduces the femtosecond laser nano-surgery technique, which, for the first time, enabled study of nerve regeneration in its evolutionarily simplest form, and led to very unusual observations.Location: Hughes Aircraft Electrical Engineering Center (EEB) - 248

Optimal Flooding Search in a Large Network
Thu, Apr 28, 2005 @ 02:30 PM - 03:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Prof. Mingyan Liu, University of MichiganAbstract:In this talk I will consider the problem of searching for a node or an object in a large network. Applications of this problem include route establishment in a mobile ad hoc network, data querying in a wireless sensor network, and file searching in a peer-to-peer network. We will limit our attention to the class of controlled flooding search
strategies where query packets are broadcast and propagated in the network until a preset TTL (time-to-live) expires. Every unsuccessful search attempt (signified by a timeout) results in an increased TTL value (i.e., larger search area). The primary goal is to derive strategies that will minimize the search cost associated with packet transmissions. We consider two cases. When the probability distribution of the location of the object is known a priori, we present a dynamic programming formulation with which optimal search strategies can be derived. We also derive necessary and sufficient
conditions under which two widely used search strategies are optimal. When the probability distribution is not known a priori, we adopt a worst-case cost measure which is also the competitive ratio with respect to an oblivious adversary. In minimizing this cost measure we show that the best strategies are randomized strategies. We then derive an asymptotically (as the network size increases) optimal randomized strategy, and compare its performance with its deterministic counterpart. We will also explore a number of simple but suboptimal strategies. Speaker Bio:Mingyan Liu received her B.Sc. degree in electrical engineering in 1995 from the Nanjing University of Aero. and Astro., Nanjing, China, M.Sc. degree in systems engineering and Ph.D. Degree in electrical engineering from the University of Maryland, College Park, in 1997 and 2000, respectively. She joined the Department of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor, in September 2000, where she is currently an Assistant Professor. Her research interests are in performance modeling, analysis, energy-efficiency and resource allocation issues in wireless mobile ad hoc networks, wireless sensor networks, and terrestrial satellite hybrid networks. She is the recipient of the 2002 NSF CAREER Award, and the University of Michigan Elizabeth C. Crosby Research Award in 2003.Location: Hughes Aircraft Electrical Engineering Center (EEB) - 248
