extruder samples and stuff yeah good you go well we're bring some I'll I'll bring some stuff to pass around so you guys could look it up up
extruder is right next to the nozzle um kind of like the one you're passing on this side like the the drive systems
the extruder um so like I explained before this is a kind of a very fancy hot glue gun and it's pretty simple the
you have four extruder Motors driving that and extruding and you have software dealing with which one should extrude uh
up and you extrude it.
main part of the extruder is kind of this one um um it's not the most important because they all have to kind
printed version of an extruder
head or your extruder very light and having that extruder light makes makes things move faster and you could do a
But the new smart extruder-- there's three sensors in there.
And then they extruded a boat.
And it extruded these epoxies, which actually made that concrete stronger in the end.
And then you fold it up and extrude a shape.
start extruding right before it needs to extrude and then retract a little before it needs to retract because there's a
And then those squares have colors that extrude off the squares.
move in 3D space um the extruder is what kind of spits out the material basically
you can move the the extruder which is dispensing the the material that could just stay steady and you can move the
in two directions uh uh for the extruder and then the the Z platform would move
direction uh you kind of need the extruder to be pretty light um you can't put like a it's not you can't it's a
way it works um the extruder basically consists uh it starts off at the top where the material comes in it has
it um there's some extruders there there's like another 20 ways to make an extruder
every time the the the the extruder motor pushes the filament there's a little compression trickle compression
when we started I created a dual extruder machine and found out a lot of techn uh technical issues with doing
Tube of cold plastic goes through extruder that heats it up too hot plastic, turns plastic to hot frosting,
They all have this smart extruder, which just swaps in and out, so if you need to replace it, and it's got a little brain in it,
The cool thing with the smart extruder though is it just pops off, and it's held on by magnets.
just for fun made a frosting extruder so that you can automate the Cupcake Decorating process but a cupcake will fit in there as well to give people an
feed rate with some other extruder on extruder off commands sprinkled in there for good measure um it has a little
glue and being getting a Crayola crayon extruder for you know 64 colors of
Then another one, and extrude it.
They were using bacteria that basically had been modified to extrude epoxies when in contact with cement.
system to move the X head or yeah the extruder up um and I decided to do this
close um but the this is a typical design of an extruder which has a a heater cartridge through the hole um and
printers all right um and now there's two different ways to extrude this plastic there's kind of like a a remote
They are now experimenting with putting indigo in the fiber when it's extruded .
platform in X and Y or you could do a combination of those where the extruder just moves in X and then moves up also
system as this um but we had the uh you could see the extruder in the middle and
straight cool and uh and since you're kind of moving the extruder um in every
the way up as thing as time goes by obviously um so most of these extruders
company also you guys could trade um and this is the whole extruder uh mechanism so you could see the that heat
just called direct drive um The bukit Works in a Bowen uh extruder way and the advantage of that
end um cool and and then there's machines that have multi- extruders uh
that all right um and then the another little important thing about uh extruders is that there's some materials
all your 3D printing for it um like that orange machine with all the extruders
So if and when we ever do do an upgrade to the extruder, you can just by an extruder rather than a whole new 3D
And we have some limitations on how much heat we can have into the extruder, which limits it.
And in the case of polyester, we can actually melt it down and extrude it into new fiber that's of equal quality to the
of light and there's so much room inside that bundle of light for you to extrude different parts of the photo in
It's the spiders have many glands, and each gland extrudes a different type of silk for a different purpose.
machines like this they're kind of more boxy um and stuff they usually work in the X and Y as the extruder and then the
tight and the motor stronger and all that so instead what they do is they put the extruder somewhere else and they
