Do you want to 3d print faster on your Ender three
style printer i'll show you some tricks in cura to take a five and a half hour printed arm and
do it in three right here on Filament Friday. Filament Friday is brought to you every week
by the generous donations of these patreon supporters. there are printers out there which
will print faster than an ender 3 or ender 3 clone like the voron 2 that's a real popular one
right now or a delta printer like the see me cnc artemis that i have. it prints a lot faster.
but those will cost you a lot more money so the question is, are there things you can do
to your prints to make them actually print faster? yeah there is for example this side spool
holder that i showed in a previous video. just the arm, not even the pivot, just the arm
itself if i print it at a point two layer height it would take almost nine hours to print.
If i do
it at a point two eight layer height then i save a lot of time. get it down to about five and a half.
but i had a viewer take this, change the design to a much simpler design, and get it down to about
three hours. but i like this design with the zigzag. it looks more like you know eiffel tower
type of build. well i was able to do that in cura and still maintain that roughly three hour
print. and i did it using tricks i've showed you in previous videos on cura.
So let's take
this bring it into cura and i'll show you how we get from this to this. here it is brought into
cura i'm using the ender3 max machine profile to give me more space. let's slice it at 0.2 layer
height. it's got 3 walls, 15 percent infill, and supports just where it's touching the build plate.
slice it, 8 hours and 43 minutes. almost 9 hours to print just this arm. in detail shows us it's
mostly inner and outer walls taking the time. i'll use my 0.28 profile that should speed things
up with the same settings. so we'll slice it and we get 5 hours and 57 minutes almost 6 hours.
inner and outer walls are the main time users. it's all the inner and outer walls and these
crosses are treated as outer walls.
They're nice and smooth inside. you want the outside
to be smooth because that's what you see. so it prints slower. but your infill and things
like that can print faster because you'll never see it all. these crosses are outer walls so they
come out really nice but that takes time. so i had a viewer take this design and simplify it. and
they actually got rid of all these crosses and just made it nice and smooth. let's take a look
at that. on thingiverse builder red cross took the design and made it smoother. he made the top and
bottom smoother and got rid of all those crosses. and in the process it prints faster. he
claims five hours instead of nine hours at point 0.2 layer height. and he's right
it prints faster. let's take a look at it. here's his design brought into cura.
You
can see it's smooth on top and bottom no more criss-crosses. i'm going to slice it at
a 0.28 layer height so it should be faster. after slicing three hours and 10 minutes.
so i just took it down two more hours. and you see the biggest category is skin the
outer skin no longer inner and outer walls. but i like this zigzag. i like that look that's what
i want. so am i stuck with a long print? well no there's tricks in cura that you can get that
same effect. let me show you how to do that. i showed this in a previous video where you can
actually make the top and bottom layers zero so that way exposes the infill. so i set it to 0 here
and let's slice it again and see how it looks. i reduced it down to 2 hours and 16 minutes.
but let's take a look at it in preview all the infill is now exposed.
I'm getting
a crisscross pattern, kind of. it's not the pattern that i want, but i can see all the way
through the arm. so let's change the pattern. i'm going to go into the infill settings and i'm
going to change it to 10 percent infill like my profile normally has. and i'm going to change grid
to triangles. now let's slice it again and see how it looks. as you can see it's starting to look
more like the original. but these infill walls are really thin. so you can actually make them thicker
which i've showed in a previous video.
