Print Faster on Your Ender 3 Style Printer Using Tricks in Cura

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.

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.
