This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Due to the additive way of manufacturing parts layer by layer, additive manufacturing (AM) is subjected to fewer design constraints than traditional manufacturing techniques. The intricate and complex structures that cannot be fabricated by traditional methods can be realized by AM. However, it should be noted that the manufacturing capability of AM is not limitless. The unprecedented design freedom of AM can only be fully utilized when the unique manufacturability of AM is well investigated and the design methodology specially for AM, also known as design for AM (DFAM), is developed.One popular topic of the DFAM research is to propose feature-based design guidelines based on experimental investigations. These simple-to-follow rules normally oversimplify the dependent relation between the manufacturability of features and their corresponding manufacturability parameters. To compensate for this shortcoming in the design guidelines, manufacturability analysis is needed to examine designs before manufacturing takes place. In this thesis, a computer-aided design evaluation (CADE) system is proposed to perform manufacturability analysis on computer-aided design (CAD) models for the specific AM process. The CADE system consists of three consecutive modules: feature detection, feature evaluation and orientation optimization. Logical rule-based method, artificial neural network (ANN) and genetic algorithm (GA) are used to develop the three modules, respectively. A design of experiments (DoE) method is proposed to study the AM manufacturability with respect to selected aspects of geometric dimensioning and tolerancing (GD&T) in a comprehensive yet economical way. The proposed framework is implemented for the binder jetting additive manufacturing (BJAM) process. Based on the proposed DoE method, the manufacturability of overhang structures and through holes are investigated experimentally with respect to angularity and cylindricity respectively. The knowledge and experimental data gained in the extensive experimental work are then used to develop the CADE system. With the support of the developed CADE system, designers can examine critical features in their designs from the manufacturability perspective for the specific BJAM process. In this way, the features that are prone to failing are identified in advance so that designers could modify them to decrease the risk of manufacturing failures." --

Download or read book Towards Design Automation for Additive Manufacturing written by Anton Wiberg and published by Linköping University Electronic Press. This book was released on 2019-10-14 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, the development of computer-controlled manufacturing by adding materiallayer by layer, called Additive Manufacturing (AM), has developed at a rapid pace. The technologyadds possibilities to the manufacturing of geometries that are not possible, or at leastnot economically feasible, to manufacture by more conventional manufacturing methods. AMcomes with the idea that complexity is free, meaning that complex geometries are as expensiveto manufacture as simple geometries. This is partly true, but there remain several design rulesthat needs to be considered before manufacturing. The research field Design for Additive Manufacturing(DfAM) consists of research that aims to take advantage of the possibilities of AMwhile considering the limitations of the technique. Computer Aided technologies (CAx) is the name of the usage of methods and software thataim to support a digital product development process. CAx includes software and methodsfor design, the evaluation of designs, manufacturing support, and other things. The commongoal with all CAx disciplines is to achieve better products at a lower cost and with a shorterdevelopment time. The work presented in this thesis bridges DfAM with CAx with the aim of achieving designautomation for AM. The work reviews the current DfAM process and proposes a new integratedDfAM process that considers the functionality and manufacturing of components. Selectedparts of the proposed process are implemented in a case study in order to evaluate theproposed process. In addition, a tool that supports part of the design process is developed. The proposed design process implements Multidisciplinary Design Optimization (MDO) witha parametric CAD model that is evaluated from functional and manufacturing perspectives. Inthe implementation, a structural component is designed using the MDO framework, which includesComputer Aided Engineering (CAE) models for structural evaluation, the calculation ofweight, and how much support material that needs to be added during manufacturing. Thecomponent is optimized for the reduction of weight and minimization of support material,while the stress levels in the component are constrained. The developed tool uses methodsfor high level Parametric CAD modelling to simplify the creation of parametric CAD modelsbased on Topology Optimization (TO) results. The work concludes that the implementation of CAx technologies in the DfAM process enablesa more automated design process with less manual design iterations than traditional DfAM processes.It also discusses and presents directions for further research to achieve a fully automateddesign process for Additive Manufacturing.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The interests towards Additive Manufacturing (AM) technologies are rapidly rising due to their great potential in new product design possibilities and the reduction of environmental impacts. Currently AM technologies are largely investigated in automotive, aerospace and medical equipment industries on design, production quality and manufacturability aspects. Due to its inherited layer by layer fabrication process, there is a concern regarding to the manufacturing efficiency of AM processes. However, there is very limited research on productivity of AM, which includes the time consumption, raw material consumption and the production efficiency. This paper presents a simulation method to assess the productivity of AM. Based on this method, a productivity model of Binder-Jetting AM technology is created. Binder-Jetting AM (BJAM) is one of the commercialized AM technologies which can process a variety of materials including stainless steel, ceramic, sand and polymer. Process decomposition is performed to analyze the BJAM printing process. Curing and sintering process as well as manual processing procedure are also included as part of a complete production system of BJAM. Life Cycle Assessment (LCA) model is developed in order to evaluate the whole production process and the production-consumption relation. Experiments are conducted in order to collect data on operation and manipulation time of the machine and actual material consumption. Based on experimental data, an evaluation algorithm has been developed in estimating the time and material consumption as a function of part geometry and process parameters. Several process parameters are taken into account, including the layer thickness, spreading speed, drying time, binder saturation, drying power and curing and sintering profiles. Furthermore, the production efficiency is assessed on adapted Key Performance Indicator (KPI). Machine Availability, Machine Efficiency, Material Efficiency, Material Consumption Ratio, Waste Ratio and Machine Preparation degree are considered. An estimation of the production time, material consumption as well as the KPIs from the given STL design file and the recommended process parameters is given as the output of the productivity model. Finally, A Case study is performed to validate the BJAM algorithms and productivity model. The result shows that the Productivity Model can provide reliable estimation of the time and material consumption of the BJAM production system." --
