Our theme this time is the Cuban chain
Before everyone starts watching the video
I suggest you take a look at the link to the manual video in the full description
Let's first understand how the handwork is done
Let’s look at the way of 3D modeling
This way it will not make a chain with insufficient strength
The basic elements of the chain can be made with rings
But I want to demonstrate the changes in details
So I use circle first
Number of vertices 8
If the radius is the same, use 8 and wait to see the difference will be more obvious
(Add subdivision surface modifier)
S Y shrink the Y axis to make it a bit elliptical
Remember to apply rotation and zoom (Ctrl+A)
Offset extrusion 5 (need to enable the built-in Add-on Edit Mesh Tools)
Use the materialization modifier to make the thickness
Remember that the order of materialization modifiers should be before the subdivision
First use 6 to see the thickness
Let’s add a simple deformation modifier to twist
This is simulating the process of twisting the chain manually
The angle can be bigger
Use 60 degrees
Or 90 degrees, depending on the feeling the object wants to show
Then add the array modifier
Adjust the distance
Now this distance is relatively wide
Looks less like a Cuban chain
So adjust it to make it denser
When we do it more densely
Here you will see that the overlapped part has also increased
Handmade words
The overlapping part will be knocked or rolled with a tablet press
Use external force to squeeze out the shape of the chain
This can be seen from the recommended video
OK continue to adjust the distance and shape
The thickness of the materialization is also increased a bit
Pay attention to the thickness of the overlapped side when adjusting
Let's flatten the top to see the effect
Simply use a square and Boolean to flatten
(Mirror make the other side)
(Brin's Difference)
(Adjust the order of modifiers)
Continue to see how you can adjust
Cut it down a bit more
Also adjust the size of the inner and outer circles
Um, the thickness now seems a bit too much
This ratio is better
Let’s make some changes to the shape of the side to add features
This must first apply the materialization modifier
Then enter edit mode
Use Loop Cut to make the center line
Cut the center line on the upper and lower sides
Adjust shape
Like this to make a more angular feeling
Use the side line to crease and strengthen it
In this way, many changes can be made on the side
The concave effect like this is pretty good
This is the reason why circles and materialization were used as basic objects in the beginning
I’ll just do it back to the basic style this time
I have to adjust it here
OK and the shape of the Cuban chain is complete
Then complete the basic components
First apply the modifier above the array
Let's use the array to make the front and back arrangement
Copy the array modifier once to make the other side
Just add a-and it will be symmetrical
Then apply two array modifiers
Enter edit mode and separate the middle component first (P)
Then because the array has twice
So there will be two in the middle, remember to delete the more one
After finishing, there must be two objects on the outside and the middle
Then we look at the structure part
Now the overlap between components and components is actually not small
Make a difference to see more clearly
After Brin, you can see that some parts of the component connection are actually quite thin.
In the production, this part needs to be extruded with components
So that the chain can retain a certain strength
So if you want to use 3D printing as the basic element of the chain
We also suggest to make the appearance
In the future, we still have to return to the practice of manual chains
After the basic components are soldered
Then use extrusion to make the groove
The most is to dig a positioning trench to facilitate subsequent extrusion work
This is what we recommend for this kind of object
But we have to render
So this part is still dig out first, the rendering effect will be better
Next, after turning on the coloring and smoothing, you will see strange reflections on the cloth surface
Although this situation can be improved by automatic smoothing
But the three-dimensionality rendered by this large plane will become worse
So we have to do some processing on this plane
Use Select Similar to select 4 planes
Then press E S Z to extrude a little bit on the Z axis
Then change the pivot point to individual origin
Press S Shift+Z to make them smaller toward the center
Continue to press Ctrl+B to do a little chamfer
After the edges are chamfered, the three-dimensionality of the rendering will be much more obvious.
Fine-tune
This point is too much, melt it away
Then add a curved circle
The length of the chain should be longer and the radius should be 90
Let's add the array modifier again
Next, change the adaptation type of the array to the adaptation curve
The goal is this curve
This will automatically calculate the number of arrays according to the length of the curve
Then there is the curve modifier
The object is like this curve
This makes a full circle
Then select the curve to turn the chain
Enter edit mode (curve)
Change the tilt directly to 90 degrees (select all)
This way the chain will turn right
Next is the material
Use yellow gold this time
And this HDRI is this
The power of comparison/multiplication is 2
Then look at the results of the calculation
OK, no problem with calculation
You can try to make more changes on the side
Make various distinctive chains
