PRODUCT SHOWCASE
Industrial-Scale 3D Printing of
High-Strength Carbon Fibre Parts
Markforged, represented in Australia by Emona Instruments, has
announced the industry’s most
powerful fibre-composite 3D printer, the Mark X. The Mark X’s high
strength carbon fibre 3D printed
parts will be in demand for both
prototyping and manufacturing
scale parts printing for mining,
manufacturing, renewables, medical prosthetics and electronics/telecommunications applications.
In addition to the large print volume of 330mm x 250mm x 200mm
(X, Y, Z), it has in-process laser inspection as well as a fine (50 micron) surface finish to make this
one of the most powerful, precise,
and unique 3D printers on the market today.
“We have taken a different path
from most of the 3D printing industry with innovation that will create
a new bottom line benefit for many
manufacturers” says Greg Mark,
CEO and founder.
“We already had success with
the breakthrough strength and light
weight of continuous carbon fibre
in our Mark Two printer – now we
have added in-process inspection
for exact dimensional accuracy,
high resolution beautiful surface
finish, and scale to open entirely
new segments of the industry to efficiencies of what printing can accomplish.”

PCBCart’s aluminium-backed PCBs:
heat dissipation and light weight
Aluminium PCBs contain a dielectric layer
between aluminium base and copper foil.
The dielectric layer is thermally conductive but electrically insulating, so
that it offers better heat dissipation than
conventional PCBs. Furthermore, the
dielectric layer has such a low thickness that aluminium PCBs are light
in weight, compatible with the miniature requirements of modern electronic
products.
Aluminium PCBs are largely used for
LEDs, power equipment and automotive systems.
For better heat dissipation, there
are FR4 and through-hole aluminium PCBs. Minimum drill diameter can be as small as 8mil and minimum annular ring, 4mil.
For high-frequency and high-density PCBs, multi-layer aluminium PCBs can be made with up to 24 layers and a minimum trace or
spacing as small as 4mil.
PCBCart can make aluminium PCBs with board thickness from
0.8mm to 5.0mm and
a maximum size of Contact:

Electrolube’s New Generation
of High-Performance Resins
Electrolube, the global manufacturer of electro-chemicals,
will shortly launch five key new
resin products for automotive,
electronics and LED manufacturers.
ER2223 is a black, very high
temperature, stable epoxy resin
with a wide operating temperature range of -40 to 180°C and is designed to meet automotive under-bonnet requirements.
ER2224 is a thermally-conductive epoxy resin system, featuring
an improved method of cure, high thermal conductivity and good
thermal cycling performance. It is also suited to automotive applications and LED lighting units.
ER4002 is a flame-retardant epoxy resin with excellent electrical
and high temperature performance and an operating temperature
range of -40 to +150°C. The resin is suitable for the encapsulation
of delicate electronic and electrical components and features low
mixing viscosity and good flow characteristics.
New polyurethane resin systems include UR5638, a tough, low
exotherm resin, which provides a clear, transparent finish. UR5638
is particularly suitable for encapsulation of larger LED Contact:
lighting units.
