Material
Jetting Market Overview
The
term 3D printing has become widely recognised in the last few years,
but hardly anybody would know the term ‘Additive Manufacturing’.
In reality, 3D printing is just one of several Additive Manufacturing
techniques. While the media likes to use the term 3D printing to
refer to all AM processes, there are actually 7 different categories.
They are VAT Photopolymerisation, Binder Jetting, Material Extrusion,
Powder Bed Fusion, Sheet Lamination, Directed Energy Deposition, and
Material Jetting. The Material Jetting Market is responsible for
creating objects in a similar manner to a 2D inkjet printer. The
material is thrust onto a build platform with either a Drop on Demand
(DOD) or continuous approach. Once jetted onto the platform, the
material solidifies and the object is built in a layer by layer
approach. The nozzle depositing the material moves in a horizontal
fashion across the build platform.

Machines
in the Material Jetting Market vary in size, complexity and their
methods of controlling the method of depositing the material. The
materials are then treated with ultraviolet light which hardens them.
The number of materials available to use in this method is severely
limited, as it must be deposited in drops. The most suitable and
commonly used materials are polymers and waxes due to their adhesive
nature and ability to form drops. Some of the polymers used include
HDPE, PS, PC, HIPS, ABS, EDP and Polypropylene. Material jetting is
the only form of additive manufacturing that can combine different
printing materials within the same 3D model in a single print job. It
is also capable of making functional assemblies, reducing the need
for multiple builds.
Material
Jetting Market Drivers
The
material jetting market has major utility in the field of biomedical
technology. Most healthcare infections are because of biofilms which
form on the medical device surface. They develop a higher tolerance
to antibiotics and the immune system compared to their planktonic
counterparts. Material jetting allows a precise morphology, size and
shape for printed devices. Human tissue, pressure sensitive fingers
and smart limbs have all been created using this revolutionary
technology.
A
second driver is the reduced manufacturing time and resources along
with the advantage of being able to use multiple materials in one
print. Products can be made and customised in specific areas where
different materials are placed. This removes the need to print
separate layers of various materials and combine them later. In one
production run, a complete product can be created with unique
materials only in the material
jetting market. The printing method makes products with a
layer resolution as low as 15 microns.
Material Jetting Market Restraints
A
major restraint in the material jetting market is the limited
materials available to use. While it provides a high degree of
accuracy, only some waxes and polymers like HDPE, PS, PC, HIPS, ABS,
EDP and Polypropylene can be used. Material jetting is a very complex
procedure, with several technical issues throughout the process. One
challenge is formulating the liquid material for example. If the
material is not liquid in the beginning, particles might need to be
suspended in a carrier, dissolving the materials in a solvent,
melting a polymer, or mixing a formula of monomer or prepolymer with
an initiator. The second technical challenge is formulating and
depositing the droplets. The material needs to be converted from a
liquid into small discrete drops. After this, the droplet fall path,
impact, and interaction or wetting must all be properly controlled.
This complexity inevitably leads to a cost increase of the overall
process, challenging the growth of the material jetting market.
Material
Jetting Market Key Regions
North
America is the largest material jetting market due to a large number
of high-tech industries like aerospace & defence, automobile
manufacture, and healthcare companies. All these sectors either
already use or plan to use material jetting technology. Asia Pacific
accounts for the fastest growth rate with China and Japan in
particular leading the way because of government funding in R&D
and an established manufacturing base.
