Custom Manual Supports in Cura 4.3

On some 3d prints you want to actually
manually place your supports and not put supports throughout the whole print
because that’s a lot to remove and a lot of wasted plastic some of the slicers
like simplify 3d or idea maker allow you to do that to actually put supports
where you want it well what about cura cura lets you do it with a plugin and
I’ll show you how to use it today’s Filament Friday, this week’s filament Friday is
brought to you by these patreon supporters. to demonstrate manual
supports in Cura I’m going to use this iron man shooting statue I found on
Thingiverse from user Melic. I loaded it into cura version 4.3 but I’m going to
reduce it down to 50% of its original size I’m also going to turn it 45
degrees this will make it easier to put manual supports where I want them on
this model once it’s sliced here’s the model I’m going to scroll down there’s
three areas that I think it needs supports one under the hand here another
one here between the legs and I’m not going to comment and what that looks
like and also under the arm here where you see these little islands of plastic
those need supports. the rest of this model I think will print without
supports pretty cleanly so I’m gonna enable supports I’m gonna set it to
everywhere and then these are my standard settings 45 degrees it won’t go
through them again I did in a previous video but here’s the supports all over
the place it’s just everywhere in this model it’s going to take a lot longer to
print and use a lot more plastic and a lot more cleanup so I don’t want to do
this if I don’t have to so let me change the settings and show you one other
option they give you which is touching the build plate now will this fix it no
because all it does is what’s touching the build plate which is the hand here
you’ll go straight down the build plate everything else is off the platform so
all the areas that I wanted to support aren’t supported a way around that
within cura is the support blocker what it does is allow you to put these blocks
all over the print and wherever that block is it will not put supports now
it’s just like an STL file you can resize it move it
so you position it where you don’t want supports and then when you do supports
and I’ll change this back to everywhere where that block is it
won’t print supports so you can see the head is clean so what you have to do is
put these blocks all over your print or you don’t want supports there’s another
option instead of putting blocks where you don’t want supports how about
putting blocks where you do want supports that’s what custom supports
does but this isn’t standard in cura you have to load it from the market
place so go up to market place scroll down to custom supports this is a plugin
click on install and then you have to click on their license agreement and
then quit cura and restart it now will show up on the Left menu so you click on
your model and you click on custom supports and then you place the blocks
where you want support so here’s the locations that I designated I’ll put
blocks in each one of these then you size them and reposition them the same
way I did the support blocker so let me just show you on the hand here I’ll do
it real quick so I up size it to 400% then I slid it so is centered to the
hand down sized it to 300% and then repositioned it so it touched all the
points that I want the supports to touch and here’s the trick you don’t check the
generate support box and then it’ll only generate supports where those blocks
were like here on the hand that I just showed you positioned so now I’ll scroll
down and you can see I have very dense supports but I did that so I can get the
real tiny pieces of the hand and then as I scroll up this thing will form right
around the hand supporting where it needs to like the little shield that’s
outside the hand ironically if you want to change those support settings you
have to enable support so the menu shows up and then you can change things like
support density I had it at 80 I’ll change it back to 60 and then also the
support interface for the top and bottom I took that off and this is why because
when I had that enabled it was missing the tiny piece of the finger and I like
the more dense 80 percent versus a 60 percent so I set those back and but here
it is without the interface and it looks much smoother so now I need to
reposition the center one and also the ones under the arms so let me just show
you I already did and here’s the finished product so
here’s the blocks and when I slice it it gives me the supports I want that a
little islands under the arm are taken care of and in here in the center it’s
handled and then also on the hand it’s just like I showed you before I didn’t
change that but I did set it back to the 80%
now I forgot I actually reduced it down to 40% of the original size before I
printed because I wanted to try smaller but look at the time it’s a little over
three hours three and a half hours and five hours and ten minutes if I do the
full supports so not only do you save you know plastic and removal time but
you actually save print time using this as well
so to me there’s a lot of advantages to using these manual supports here’s a
quick time-lapse of it being printed I use atomic filaments candy-apple golden
pearl filament it looks really good here on Iron Man overall it’s a decent print
it’s a point to layer height 25% infill and I printed at a 50 millimeters per
second using my profiles so overall not too bad now let’s see how hard it is to
remove these supports actually because they’re solid I could just twist them
and as long as I don’t break that hand that should work pretty well so I kept
twisting until I felt it loosen and then I could just pull it right off the top
of it seemed really smooth the hand came out good the fingers look really good
the shield next to the hand not too bad now I needed to do the arm this one was
a little bit tougher I had to keep wiggling back and forth of different
points I could feel it breaking away but I figured if I just keep going back and
forth it should work and finally once I did it from the center it popped and
when I pulled it off the top if it looked good and the underneath the arm
not too bad a little bit of cleanup might be needed you can see a little bit
of sagging but overall pretty good support structure this middle section
was messing with me it just got breaking into smaller and smaller pieces I’m not
even going to go down that road so I finally got the supports off and then I
could look over this model there were a few spots that probably could have used
supports but overall I think this came out really good
if you haven’t tried custom supports I highly suggest you try it out give me
your honest opinion in the comments below and if you don’t like it just
uninstall it you don’t have to keep the plug-in in a previous video I showed my
support settings and also tree supports I’ll link to that at the end of this
video but this manual support feature that’s a really nice addition to the
support within cura this isn’t my best print and there’s a little bit of
cleanup for the supports word but it’s a lot less cleanup than if I would just
done the overall supports now is it as good as say what’s in simplify3d or
ideamaker or maybe some other slicer I don’t know that’s up to you guys to
judge but if you’re a cura user I really think you need to plug this in and play
with it and see how you like it if you like what I’m doing here maybe check out
some of the videos that are popping up including the one on support if you want
to help support the channel patreon is one way or just by through the affiliate
