In this video I want to show you how to edit the lithophane photo
that you made from the online tool
to the shape and the size that fit your project better.
At first, you need to make a lithophane photo out of your own photo.
Just pay attention to the size, for example
the black rectangle is the photo that you made from the website
and let's say the red area is the one that you want to taken out
pay attention so that
the size of your photo is big enough for you to do all of the cutting after.
In my case, I use this photo to make the example.
Let's go to the website that you can make
the lithophane photo with
I use the http://3dp.rocks/lithophane/ here
in the image, import the image into the into the website
then in the settings, wait for them to load
in the model setting I choose the maximum size 250mm.
This is depend on um what you want okay
you have to have more or les the size that fits your project
The thickness I chose is 3mm is good enough and reasonable thickness
so that your lithophane photo can be seen clearly
and don't need to print extremely thick photo
and then the light can come out easily
so that for the model setting.
be careful with the image setting, choose the positive instead of negative image.
now back to your model you can refresh and download your photo into desktop
let's save with stl and so that's all we need to do with the lithophane webtool and turn it off
okay now i have the stl file here
let's check with the Prusa Slicer if you have Cura you can see with it too add the photo here
so you see this is the original photo that you add into the
http://3dp.rocks/lithophane/ it looks like this.
Now i want to capture the small area here
for example this rectangle
with the four faces of the people
okay to make Blender ready for the job of editing stl file
and to be able to export the stl file
that works well with the 3d printer
I already have a video clip um how to set all of the unit so I won't repeat it here anymore
just import the file that you just made
it takes some time for the thing depend on your file is big or small
okay let's look at it from the top. If you type n you will see that
the size of the photo I make is 250 and 177 and the thickness is 3mm
let's say I want to cut a rectangle with the size of 150 and 100 for the faces only
first you need to add a new mesh which is the cube with the dimension that you want
here I will put 150 okay and yes okay this so I have 150
but as I say i want the side Y is only 100 so it's here 100.
and the Z side is the thickness, our thickness is only 3 millimeter so you
can choose whatever more than 3 should work fine.
Let's choose 8mm just for the demo
okay now if you toggle the x-ray
you'll be able to see through it and easier for you to adjust the position of the rectangle
click on the cube okay let's go to seven
click on the cube type g so you can move the thing along the all the axis here to the good position
after you already um changed the dimensions and scaled it up and moved it you should to
be sure for all of the modifier to work correctly you should uniform the size
in a way so let me uniform it by type CTRL A and all transforms
so now it's perfect you see on the scale X Y Z became 1
and it is the proper dimension back to the top view
now to cut this out of your photo
just go to the photo, you can add a modifier called boolean
In boolean, there are three options of intersect,
union and different. Different is this outside area,
intersect is the inside area and the union combine both of them.
In this case we're gonna choose the intersect okay and with the object we're gonna select
like the cube that we already made okay again it needs some time
when it's ready you will see the photo now look smaller it perfect position that we want
so you can hide the cube and now you can export back
this stl file so that you can work with 3d printer
so export stl and i'm going to save it as rectangle.stl
remember to select the
selection only check on the checkbox selection only and there you have it
now let's go to the screen you have the rectangle here okay and
let's import it into the Prusa slicer
here you see this is the photo that we got from the big photo.
let's try a little bit more with it by cutting
instead of a rectangle we're gonna cut the hexagon out of the photo
It's gonna be the same process but you have to create a hexagon inside Blender
and how to do that,
at first I'm gonna remove this modifier so we have back the photo
to make a hexagon inside a blender you could add a mesh as the cylinder
and the trick is to add these six vertices instead of 32 like defaut
so you're gonna have six edges not six vertices which is just six edges
and then the number of radius uh radius uh I want something like 168
for the diameter so the radius should be 168 by 2
and that the depth and we say whatever bigger than 3mm is fine so let's say go to eight and
I want the angle is 90 degree around Z so
now that's the one is with the correct size but we need to choose the position also
type g
move it to where you want
i'm gonna put it here okay so done it's perfect
now do the same thing choose the photo okay add modifier go to boolean add intersect
and pick the cylinder that you made and give it some time for it to process because it's
a big file okay you have it now let's hide the cylinder and choose the photo export it
stl file and save it as hexagon.stl
so here you can add the hexagon into your slicer
Using this method, basicly you can cut whatever shape that you want
from the photo that you made from the online tool
to fit your project better
Thank you for watching.
