0505 Blender Printer setup Video Lecture | Learn 3D Modelling: The Ultimate Blender Guide - Software Development

alright so we've done this before this
whole ripping process but what I want to
do is show you some things that you
should look at as far as the letters are
concerned because the letters are kind
of thin some in some places so we have
to kind of be mindful about that another
thing we should discuss is the work um
remember a 3d printer has like two
really major axes that move a lot the
z-axis up and down doesn't move a whole
lot it just moves up one little tiny
decimeter every so often just to add a
new layer but um the x and y move a lot
now on the 3d printers that I build the
Y is a little heavier because it's it's
using a mains current to heat up this
platter and the platter weighs a little
bit where the x axis is very lightweight
so what we want to think about is that
let's say this is the x axis right here
would it be better to have a carriage
that's very lightweight going back and
forth or a very heavy brick going back
and forth which is less work and I would
say well the x axes going back and forth
being lightweight doesn't do a whole lot
of work in correlation to the y axis so
always trying to line up your pieces so
that the x axis is doing most of the
work that's what I'm trying to say so in
this case I like these longer pieces to
go this way okay so I don't need any
material for generation of support a
couple these are left over from last
video and yep that's good 234 the
temperatures good and over here extruder
i do want to lower this down 2.45 and i
might even have to go lower than that
okay so let's export that
now this could take a second because
really the letters have a lot of
triangles okay so for as many polygons
there are it will take a while to do and
then we can look at that the process
within our print run to see if it
captured all the little details of the
actual texts even the thin spots now
some things that you can do to speed up
the process is to eliminate as many
triangles as possible to do that you
know you could bring it back into
blender as a still file let's say let's
say you had a repaired still file while
that's processing I'll talk about this I
could take an import the still of the
initials this is the cleaned up one drag
it down and then I can use decimate and
decimate will allow it to reduce the
number of polygons so I can decimate
this down but the minute I see some
degeneration occur so I'm just going to
click this click it click it click it
until I start seeing some degeneration
happen and degeneration happens when
you'll you'll see that these blend
that's not too bad actually so look at
the polygon count just soaring down okay
so I don't want to get greedy that's
pretty good and I can hit apply and then
I'll export that as initials little res
lr is what I put there and just make
sure when you do that if you can't make
sure you go in here and repair that
because a lot of times when you remove a
lot of triangles for something it could
cause holes so let's open and here's my
low res one and it looks perfect not
much as far as automatic repair it is
concerned but still export still and
they can call that low res
now let's hop back over to boom to
camera will play I'm pronouncing that
right I'm sure some nerd out there is
going to school me in the fine art of
saying ubuntu just like they always
linux in arduino it's so funny all right
here we go looks like the high res
worked but i just wanted to show you the
process of cleaning up and decimating
something down so it rips a little
faster you'll you'll see a significant
difference once you export that other
still but for right now I'm just going
to keep the high res and I'm going to go
into the printer interface in this case
I got three printers I'm going to go to
the newest one and let's load that file
okay double click on it and then you can
page through this just hold shift and
make sure everything is filling
correctly make sure you're getting all
the the letters if you look at the w
here it's very thin it's not having any
kind of fill between these two lines
right here okay so if you see that
that's a big red flag you could repair
it and all you do is there is you just
go back to slicer and you would lower
that down okay so in this case you would
lower this number down 2.35 and I know
that's a pretty big jump but do it even
though you have a point five head it'll
actually work out correctly anything
going past you know that much let's say
you have to go 2.25 don't do that that's
a little bit too hard and you'll see
some bad stuff occur because of the
going down too low Oh point five can
reduce all the way down 2.35 and sake
same could be said if you have a point
35 head on your 3d printer you can go
down to like what like 2.25 I wouldn't
go any lower than that so keep it within
some kind of ratio
I'm not going to edit any of this out
just fast forwarded a little bit I don't
do editing that's what the little fast
forward things were
all right now let's go look at that in
the 3d printer see how that looks like
so jump back over to my printer I'll
load the file
double click on it and you can see
clearly the W is now being filled in and
it's solid wall so that is good alright
I'm going to print this and we'll take a
look at it what I would highly suggest
is there is no real need for a fan on
this because it's not standing up
anytime an object is standing up a fan
should be probably put on it with the
amount of detail but really this is all
flat 2d 3d type of labor so you should
probably just let it ride and print it
out okay and then come back in the next
video will kind of look at things you
might need maybe not need or how the
outcome looked
