Fault diagnosis of FDM process based on support vector machine (SVM)
Emerald - Tập 26 Số 2 - Trang 330-348 - 2019
Huaqing Hu, Ketai He, Tianlin Zhong, Yili Hong
Purpose This paper aims to propose a method to diagnose fused deposition modeling (FDM) printing faults caused by the variation of temperature field and establish a fault knowledge base, which helps to study the generation mechanism of FDM printing faults. hiện toàn bộ
Calibration of shrinkage and beam offset in SLS process
Emerald - Tập 5 Số 3 - Trang 129-133 - 1999
XiangweiWang
Selective laser sintering (SLS) is one of the most successful rapid tooling processes. Shrinkage and beam offset are the two most important control parameters in this process. First, the SLS process and procedure of calibration are described. Second, based on the property of shrinkage and beam offset, a basic formula of shrinkage and beam offset is derived. Finally, the procedure of applyi...... hiện toàn bộ
Parametric optimization of fused deposition modelling process using Grey based Taguchi and TOPSIS methods for an automotive component
Emerald - Tập 27 Số 1 - Trang 155-175 - 2021
Sakthivel Murugan R., S. Vinodh
Purpose This paper aims to optimize the process parameters of the fused deposition modelling (FDM) process using the Grey-based Taguchi method and the results to be verified based on a technique for order preference by similarity to ideal solution (TOPSIS) and analytical hierarchy process (AHP) calculation. ... hiện toàn bộ
Prosthetic sockets fabrication using rapid prototyping technology
Emerald - - 2002
P.Ng, P.S.V.Lee, J.C.H.Goh
The traditional way of making a prosthetic socket is by draping a heated thermoplastic sheet over the positive mould, or by applying layers of woven materials together with acrylic resins over the positive mould. This process is extremely labour intensive, and it usually takes two to three days to make one socket. This paper presents the development of a prosthetics Computer‐Aided‐Manufact...... hiện toàn bộ

PurposeThis paper aims to present a new fabrication method for fuel cell current collectors. Demonstration of its usefulness and discussion of its impact on current collector design and performance are also given.Design/methodology/approach... hiện toàn bộ
Environmental impact modeling of selective laser sintering processes
Emerald - Tập 20 Số 6 - Trang 459-470 - 2014
Karel Kellens, Renaldi Renaldi, Wim Dewulf, Jean‐Pierre Kruth, Joost R. Duflou
Purpose – This paper aims to present parametric models to estimate the environmental footprint of the selective laser sintering (SLS)’ production phase, covering energy and resource consumption as well as process emissions. Additive manufacturing processes such as (SLS) are often considered t...... hiện toàn bộ

Fused deposition modeling of patient‐specific polymethylmethacrylate implants
Emerald - - 2010
DavidEspalin, KarinaArcaute, DavidRodriguez, FranciscoMedina, MatthewPosner, RyanWicker
PurposeThe purpose of this paper is to investigate the use of medical‐grade polymethylmethacrylate (PMMA) in fused deposition modeling (FDM) to fabricate porous customized freeform structures for several applications including craniofacial reconstruction and orthopaedic spacers. It also aims to examine the effects of differ...... hiện toàn bộ
The rapid tooling testbed: a distributed design‐for‐manufacturing system
Emerald - - 2003
David W.Rosen, YongChen, ShivaSambu, Janet K.Allen, FarrokhMistree
A new design‐for‐manufacturing method, called the geometric tailoring (GT), and the associated digital interface concept have been developed that enable the design activities to be separated from the manufacturing activities. Conditions for the successful application of this method are investigated. The GT method is demonstrated for rapid prototyping and rapid tooling technologies, where p...... hiện toàn bộ
