Mechanical characterization of parts fabricated using fused deposition modeling
Tập 9 Số 4 - Trang 252-264 - 2003
Layered manufacturing is an evolution of rapid prototyping (RP) techniques where
the part is built in layers. While most of the previous applications focused on
building “prototypes”, recent developments in this field enabled some of the
prototyping methods to achieve an agile fabrication technology to produce the
final product directly. A shift from prototyping to manufacturing of the final
produ...
The impact of process parameters on mechanical properties of parts fabricated in PLA with an open-source 3-D printer
Tập 21 Số 5 - Trang 604-617 - 2015
Purpose – This study aims to quantify the ultimate tensile strength and the
nominal strain at break (ɛf) of printed parts made from polylactic acid (PLA)
with a Replicating Rapid prototyper (Rep-Rap) 3D printer, by varying three
important process parameters: layer thickness, infill orientation and the number
of shell perimeters. Little information is currently available about mechanical
properties...
Mechanical behavior of acrylonitrile butadiene styrene (ABS) fused deposition materials. Experimental investigation
Tập 7 Số 3 - Trang 148-158 - 2001
An experimental study of the mechanical behavior of fused‐deposition (FD) ABS
plastic materials is described. Elastic moduli and strength values are
determined for the ABS monofilament feedstock and various unidirectional FD‐ABS
materials. The results show a reduction of 11 to 37 per cent in modulus and 22
to 57 per cent in strength for FD‐ABS materials relative to the ABS
monofilament. These redu...
A review of 3D concrete printing systems and materials properties: current status and future research prospects
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...
A review on quality control in additive manufacturing
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.
Ther...
Negative stiffness honeycombs for recoverable shock isolation
Tập 21 Số 2 - Trang 193-200 - 2015
Purpose – The purpose of this paper is to study the behavior of negative
stiffness beams when arranged in a honeycomb configuration and to compare the
energy absorption capacity of these negative stiffness honeycombs with regular
honeycombs of equivalent relative densities. Design/methodology/approach – A
negative stiffness honeycomb is fabricated in nylon 11 using selective laser
sintering. Its f...
Fatigue analysis of FDM materials
Tập 19 Số 4 - Trang 291-299 - 2013
PurposeThe purpose of this paper is to determine the effects of fatigue on fused
deposition modeling rapid prototyped acrylonitrile butadiene styrene (ABS)
materials.Design/methodology/approachFDM dog bones based on UNI EN ISO 527‐1
(1997) were tested at 100, 80, 60, and 40 per cent nominal values of the
ultimate stress for nine different print orientations. The samples were
cyclically stressed in...
On design for additive manufacturing: evaluating geometrical limitations
Tập 21 Số 6 - Trang 662-670 - 2015
Purpose – The purpose of this paper is to present Design Rules for additive
manufacturing and a method for their development. Design/methodology/approach –
First, a process-independent method for the development of Design Rules was
worked out. Therefore, geometrical standard elements and attributes that
characterize the elements’ shapes have been defined. Next, the standard elements
have been manu...
Mechanical properties of commercial rapid prototyping materials
Tập 20 Số 6 - Trang 499-510 - 2014
Purpose – This paper aims to relate to the study of mechanical properties of
materials used in rapid prototyping (RP). Design/methodology/approach –
Comparison of mechanical properties of commercial RP materials. The study of the
literature was the essential source of obtaining the results necessary to
complete the evaluations and to determine the property ranges. Findings –
Specifications of mech...
