1. BULK METALLIC GLASS.
ANY THICKNESS.
ANY SHAPE. ANY ALLOY.
For fifty years the commercial success
of amorphous metals has been held back
by inadequate manufacturing methods.
Now that changes.

2. Exmet AB is working with industrial
partners on several applications.
In one application, the ability of the
material to store large amounts of
elastic energy (x10 compared to high
quality crystalline steel) is exploited,
and in another application we exploit
the soft magnetic properties of the
material. Exmet AB is currently seek-
ing additional corporate partners to
help bring this disruptive new technol-
ogy to more markets.

Swedish research based company
Exmet AB has developed and patented
technology for additive manufactur-
ing (also known as 3D printing) of
amorphous alloys. Amorphous alloys
(also known as bulk metallic glasses,
BMG, and glassy alloys) lacks crys-
talline microstructure, which gives
them a number of unique mechanical,
chemical, magnetic and functional
properties such as high strength, high
elasticity, high corrosion resistance
and low magnetization loss. The key to
achieving an amorphous microstruc-
ture is rapid cooling. Sufficiently high
cooling rates are difficult to attain in
normal manufacturing methods, e.g.
casting.
Exmet AB has managed to manufac-
ture amorphous net shape compo-
nents by additive manufacturing using
either laser or electron beam based
systems. We consider our technology
to be unique.
Exmet AB has successfully processed
components in amorphous iron based
alloys in commercially available
industrial additive layer manufactur-
ing systems, based on electron beam
melting (EBM) or on selective laser
melting (SLM). We choose to start with
iron based alloys, not because they
are easy, but because they are hard.

(at.%), is shown
in the first figure. In the second figure
a AM processed sample is shown.
The critical casting diameter for this
particular alloy is approximately 5 mm
(0.2’’), and we have thus far manufac-
tured samples with thickness 20 mm
(0.8’’). The shown XRD curve and pic-
tures from optical microscopy proves
that the sample is indeed amorphous.
The following list is a compilation of
potential applications of amorphous
alloys. However, with the introduction
of our technology the number of
possible applications will increase,
since additive manufacturing inher-
ently opens up new design possibili-
ties. Especially when combined with
topology optimization:
• Low weight structural components
• Sporting goods
• Mechanical springs
• Electrical components
• Knives
• Gears
• Nozzles
• Medical instruments
• Pressure sensors
• Biomedical materials
• Fuel cells
• Antennas
• Warhead components
• Peening shots
• Optical mirrors
• Jewellery and watches
• Electronic device casings
