MJF is a form of part of it fusion
developed by HP.
MJF stands for Multijet fusion
two technology that uses a binding agent
and uses heat to fuze the agents
together to make solid
plastic parts.
Because MJF is a form of powder
bed fusion.
The main advantage it has against
all other 3D printing technologies
is you don't need supports.
All the parts are suspended
within a powder,
which also means you can get away
with more elaborate geometries.
It doesn't have to drive
the profile of every part.
It does everything in one single pass,
which reduces the layer time
and inevitably reduces the built time
MJF has a wide portfolio
of different materials
that can be used on the machines.
Currently we're only offering PA12,
but we do offer PA11 and TPU
across other technologies
and hopefully we are looking to expand
Mjf's
material portfolio in the near future.
MJF is
typically stronger than other 3D
printing technologies.
the Z axis,
which is usually the weakest of the axis
within all 3D printing technologies,
MJF is slightly stronger
because the layers aren't just deposited
on top of each other,
they actually fuzed within each other.
our main limitation is our build volume
of 380 by 280 and 380.
Anything that fits within
that we can print
Another limitation we have found is bigger
bulky parts.
These can be printed,
however they are subject to problems
with heat during the printing process.
We have a variety of ways
of hollowing these parts
within our pre-print process
to ensure that both the part is strong
and accurate,
because 3D printing is additive
manufacturing.
We're only using the material required
to make the part versus
with subtractive manufacturing,
where you taking the material out
and away to get the part that is needed.
If we compare MJF to injection molding,
the single podcast is slightly higher.
However, you don't need the initial
tooling costs to get started
or the minimum order requirements
that injection molding sometimes requires.
could also offer flexibility
if you need to change your design.
There is no changes needed in the tooling,
and as you
ramp up your own production,
we offer price breaks for higher numbers.
We guarantee
that all tolerances will be accurate
in 0.3 of a millimeter.
Every day we do
what's called a RAMP calibration test,
where we test the accuracy
of every single build that comes out,
which means that we see results closer
to 0.1 of a millimeter
whether you're using MJF to prototype
or to print end use parts,
the results are exactly the same.
So you'll be receiving the exact
same high quality Part
Whether you're prototyping
or you're creating end use Parts
When you order MJF,
you get access to almost all of our post
processing technologies.
We offer polishing
to get a smooth surface.
We offer dyeing
to Change the color of your part.
We offer shot painting to get
a more professional look to your part.
We offer vapour Fuzing which will get you
a nice glossy look to your part,
And we also offer threaded inserts
to add mechanical fasteners to your parts.
When it comes to the best design practices
for MJF
we find that you can get away with a lot
more than traditional manufacturing.
You can have variable
wall thicknesses in your parts,
you can have hidden channels
to run any cabling
or anything like that, because you don't
have the need for support material
You can also create undercuts
and overhangs,
which you can't do
with traditional manufacturing.
And for complex parts, you can avoid
having multiple tools to produce it
by printing everything in a single part.
