This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work is to develop a comprehensive set of experiments for the investigation of the effects of Directed Energy Deposition (DED) processing parameters on dimensional accuracy. Dimensional accuracy, defined as the quantitative assessment of the agreement between the intended geometry and the final geometry of the deposited part, is understood to be one of the most important aspects of quality of an Additive Manufacturing (AM) process. This outcome is generally defined by the heat input affecting dimensions of the process including the capture efficiency of the injected powder, melt-pool size, and thermal cycling of the deposited part. Experiments were designed to generalize the effects of common DED processing parameters and their interactions on dimensional accuracy measured in situ and post-process. The experimental measurements assisted the development of validated, thermo-mechanical models that determined deformation-causing mechanisms in ways that traditional, measurement strategies fail. These models can act as a predictive tool in the assessment of the dimensional accuracy of subsequent directed energy depositions.

Download or read book Process Parameter Optimization with Numerical Modelling and Experimentation Design of Binder Jet Additive Manufacturing written by Sairam Vangapally and published by . This book was released on 2017 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Binder jetting technology is an additive manufacturing technology in which powder materials are binded together layer by layer forming the product from input CAD model. The process involves printing the product layer by layer, curing and sintering. The mechanical properties of 3D printed samples varies based on process parameters, hence there is a need to tune the process parameters for optimal characteristics. Three main parameters namely layer thickness, sintering time and sintering temperature were identified and the study focuses on the effect of parameters on dimensional accuracy and compressive strength of the samples. Full factorial experimental approach was used to conduct the experiments and analysis of variance was performed to determine the significance of parameters. Along with parameters optimization, feed forward back propagation artificial neural network model is developed to quantify the relationship between three parameters and compressive strength, the model is developed based on experimental data and validated with known data. Also, Compressive behavior of four lattice designs considered in the study were simulated by finite element analysis and numerical results were compared with experimental data in order to validate the finite element model. FE models of different lattice designs were developed from experimental test data using ANSYS and the simulated compressive behavior is compared to that experimental compression test results.

Download or read book Precision Metal Additive Manufacturing written by Richard Leach and published by CRC Press. This book was released on 2020-09-21 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) is a fast-growing sector with the ability to evoke a revolution in manufacturing due to its almost unlimited design freedom and its capability to produce personalised parts locally and with efficient material use. AM companies, however, still face technological challenges such as limited precision due to shrinkage, built-in stresses and limited process stability and robustness. Moreover, often post-processing is needed due to high roughness and remaining porosity. Qualified, trained personnel are also in short supply. In recent years, there have been dramatic improvements in AM design methods, process control, post-processing, material properties and material range. However, if AM is going to gain a significant market share, it must be developed into a true precision manufacturing method. The production of precision parts relies on three principles: Production is robust (i.e. all sensitive parameters can be controlled). Production is predictable (for example, the shrinkage that occurs is acceptable because it can be predicted and compensated in the design). Parts are measurable (as without metrology, accuracy, repeatability and quality assurance cannot be known). AM of metals is inherently a high-energy process with many sensitive and inter-related process parameters, making it susceptible to thermal distortions, defects and process drift. The complete modelling of these processes is beyond current computational power, and novel methods are needed to practicably predict performance and inform design. In addition, metal AM produces highly textured surfaces and complex surface features that stretch the limits of contemporary metrology. With so many factors to consider, there is a significant shortage of background material on how to inject precision into AM processes. Shortage in such material is an important barrier for a wider uptake of advanced manufacturing technologies, and a comprehensive book is thus needed. This book aims to inform the reader how to improve the precision of metal AM processes by tackling the three principles of robustness, predictability and metrology, and by developing computer-aided engineering methods that empower rather than limit AM design. Richard Leach is a professor in metrology at the University of Nottingham and heads up the Manufacturing Metrology Team. Prior to this position, he was at the National Physical Laboratory from 1990 to 2014.

Download or read book Materials Development by Additive Manufacturing Techniques written by Paolo Fino and published by MDPI. This book was released on 2021-03-19 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) processes are gaining more and more attention from many industrial fields, mainly because they are revolutionizing the components’ designs and production lines. The complete industrialization of these processes has to be supported by the full understanding of correlation between AM building conditions and the final materials’ properties. Another critical aspect is that nowadays only a reduced number of materials processable by AM are available on the market. It is, therefore, fundamental to widen the materials’ portfolio, and to study and develop new materials that can take advantage of these unique building processes.

Download or read book Dimensional Interchangeability in Additive Manufacturing written by Aditya Savla and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) is growing at a very fast pace. Its applications have expanded from rapid prototyping for wide range of design and engineering applications to now a more large-scale manufacturing application. AM processes can create complex, freeform shapes while also introducing features such as internal cavities and lattices. These complex geometries are usually not feasible and/or very costly with traditional manufacturing processes. The geometric freedoms associated with AM create new challenges in maintaining and communicating dimensional and geometric accuracy of parts produced. Some of the notable drawbacks in AM include the difficulty to predict how exactly components distort or shrink after the print process along with a need for post processing. These limitations have plateaued the scalability of AM processes. For many applications, dimensional accuracy is critical for functionality and/or acceptable assembly. There exists limited research with regards to the concept of interchangeability and assemblability in AM. Most research studies focus on optimizing process parameters to achieve the best possible quality and mechanical strength of printed parts. This study focuses on creating a link between interchangeability and additive manufacturing by developing an outline for conducting interchangeability and assembly tests, helping end users design components effectively and meet functional requirements for assembly of these components. This will help the end user make better decisions while designing components for additive manufacturing processes and produce cost effective components that are interchangeable at assembly. Findings presented here will can inform business decisions about purchasing components that are manufactured using additive manufacturing processes.
