8. Hybrid manufacturing
1. Hybrid manufacturing, refer to the combining of additive and
subtractive manufacturing processes within the same machine.
2. In this way, it is possible to benefit from the advantages of both
processes and alleviate the disadvantages of each one.
3. Post-processing technologies are categorized into subtractive
techniques, heat treatment, and chemical reaction when high precision
is required. Meanwhile, the procedure of printing and post-processing is
time consuming, and significant effort is needed to achieve the highest
quality.
9. Additive Manufacturing application in composite materials
1. Composites are engineered or naturally occurring materials made from
two or more constituent materials with significantly different physical or
chemical properties that remain separate and distinct at the macroscopic
or microscopic scale within the finished structure but exhibit properties
that can not be achieved by any of the materials acting alone.
2. The materials in a composite can be mixed uniformly, resulting in a
homogeneous compound (uniform composites), or non-uniformly,
resulting in an inhomogeneous compound (e.g. functionally graded
materials) in which the composition varies gradually over volume,
leading to corresponding changes in the properties of the composite
material.
10. Current AM technologies for composites
1. Solid based AM in composites
2. Liquid based AM in composites
3. Powder AM in composites
4. Hybrid of powder-liquid AM in
composites
Reinforced composites in AM
1. Particle reinforced composites in AM
2. Nanofibre composite in AM
3. Fibre reinforced composites in AM
11. Conclusions
1. AM technologies have experienced a substantial growth in recent
decades,, AM technologies are able to fabricate and build customized
geometry composites without extra tools, and execute multi-material
manufacturing that conventional manufacturing methods can not offer.
2. The hybridization of metal additive manufacturing with traditional
manufacturing processes fulfils objective of (1) increasing the
applicability domain and overcoming the limitation of AM related to low
productivity, metallurgical defects, rough surface quality and lack of
dimensional precision and (2) adding flexibility and fostering new
applications with traditional manufacturing process routes.
