A review on quality control in additive manufacturing
Emerald - Tập 24 Số 3 - Trang 645-669 - 2018
Purpose The usage of additive manufacturing (AM) technology in industries has
reached up to 50 per cent as prototype or end-product. However, for AM products
to be directly used as final products, AM product should be produced through
advanced quality control process, which has a capability to be able to prove and
reach their desire repeatability, reproducibility, reliability and preciseness.

Fault diagnosis of FDM process based on support vector machine (SVM)
Emerald - Tập 26 Số 2 - Trang 330-348 - 2019
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. Design/methodology/approach Based on the Spearman rank
correlation analysis, four relative temperature parameters are selected as the
input dat...
Towards the development of a smart fused filament fabrication system using multi-sensor data fusion for in-process monitoring
Emerald - Tập 26 Số 7 - Trang 1249-1261 - 2020
Purpose This paper aims to illustrate the integration of multiple heterogeneous
sensors into a fused filament fabrication (FFF) system and the implementation of
multi-sensor data fusion technologies to support the development of a “smart”
machine capable of monitoring the manufacturing process and part quality as it
is being built. Design/methodology/approach Starting from off-the-shelf FFF
compon...
A review of 3D concrete printing systems and materials properties: current status and future research prospects
Emerald - Tập 24 Số 4 - Trang 784-798 - 2018
Purpose Three-dimensional printing of concrete (3DPC) has a potential for the
rapid industrialization of the housing sector, with benefits of reduced
construction time due to no formwork requirement, ease of construction of
complex geometries, potential high construction quality and reduced waste.
Required materials adaption for 3DPC is within reach, as concrete materials
technology has reached th...
Processability of pure Zn and pure Fe by SLM for biodegradable metallic implant manufacturing
Emerald - Tập 23 Số 3 - Trang 514-523 - 2017
Purpose This paper aims to investigate the processability by selective laser
melting (SLM) of materials of potential interest for innovative biodegradable
implants, pure Fe and pure Zn. The processability of these materials is
evaluated with a more established counterpart in permanent implants, stainless
steel. In particular, the processing conditions were studied to reduce porosity
due to incompl...
Calibration of shrinkage and beam offset in SLS process
Emerald - Tập 5 Số 3 - Trang 129-133 - 1999
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
applying shrin...
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
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.
Design/methodology/approach The optimization of process parameters is gaining a
potential r...
Support fast generation algorithm based on discrete‐marking in stereolithgraphy rapid prototyping
Emerald - Tập 17 Số 6 - Trang 451-457 - 2011
PurposeIn stereolithgraphy rapid prototyping, the support can constrain the
model deformation and avoid a lot of problems such as collapse, shift, and
imbalance of the model. The support automatic generation algorithm has become
the key research of rapid prototyping technics software; however, presently the
efficiency of support automatic generation algorithm is low, and its algorithm
is complex. ...
A comparative evaluation of industrial design models produced using rapid prototyping and workshop‐based fabrication techniques
Emerald - - 2003
This paper discusses a research programme in which the 3D computer aided
industrial design geometry for a consumer product was translated into appearance
models using the contrasting techniques of workshop‐based fabrication techniques
and rapid prototyping using stereolithography. The research also examined the
capacity to extend the use of the rapid prototype components for the production
of a fu...
