3D printed Ekko sword from Arcane painted in cel-shaded cosplay style – finished build

Ekko’s sword looks cool before paint, but the cel-shaded finish is what really makes it feel like it belongs in the world of Arcane!

In this post, I will show you how I painted Ekko’s sword in a cel-shaded Arcane-inspired style and explain how you can create that animated hand-painted look on your own 3D-printed prop. All that without a postprocess!

So let’s get started!

Supplies

Printed 3D model of Ekko’s sword (print files here )
Acrylic paints (white, yellow, black, gold, brown)
Brushes
White acrylic marker (We used Posca)
Velvet clear coat
Patience

Process steps in order:

1. Print and assemble your sword

2. Get your table ready for painting

3. Prep your colours

4. Painting darker colours

5. Painting lighter areas

6. Edge paint

7. Fixing colours

8. Your beautiful sword being done! 💛

Timing

Printing: 25h blade, 28h gold parts (save time printing on 2 printers)
Assembly: 1hr
Painting: 4 hrs
Material used: 355g
Verdict: Can be done in the “last minute” pre-con crush week! 🔥

Step 1: Print and assemble your sword

I started by printing all the STL files. You can find all of them HERE🌟

Since I wasn’t about to do any post-processing, I used a layer height of 0.15mm so that the texture of the lines on the surface would be finer.

Bear in mind that if you want the blueish edge parts to be a little see-through, you will have to carefully select the right infill. I tested many different infils. The one that really stood out was “Hilbert curve”. This infill looks pleasant when placed in front of the light source, as it creates monotonous vertical lines that evenly fill the space. That means that the infil lets the light go through just right – not too much and not too little.

*The Hilbert curve shape infill is shown in the picture above.

Don’t forget the placement of each part in the final assembly of the sword. This will affect how you place individual pieces on your printing bed. The infill lines have to go in the same direction.

PLA Filaments I used:

Blue: Bambu Lab Teal Translucent PLA 13612

Gold: Filamentum “Cairo Gold”

Step 2: Get your table ready for painting

Before painting, prepare your table because I am sure you don’t want any color splotches on your furniture.

You don’t have to use anything fancy. I am using baking paper most of the time because of its practicality. Once I am done with painting, I simply crumble it and throw it away.

Aside from surface preparation, get a cup of water for brush cleaning, take your colours and brushes, and place them on the table.

Step 3: Prepare your colours

You will need:

White acrylic paint
yellow acrylic paint
gold acrylic paint (I had on hand Citadel Liberator Gold)
brown acrylic paint
black acrylic paint
white posca marker (or any white acrylic marker pen)

Step 4: Painting darker colours

To start your painting, I recommend inspecting your prop. One approach you can take is a realistic one, look at where the shadows would naturally form. The second one is more creative, and that means that the dark parts will be less dependent on real-world physics and more about your own stylisation.
During painting, I myself combined both ways.

You can also take inspiration from official series screenshots or any Ekko photos available.

For the darkest areas, use a mix of brown and a little black.

Then paint lighter shapes around these areas. I used a mix of gold and brown. Remember, there is no right or wrong way to paint the shapes, so just set your creativity free! 🙂

Step 5: Painting lighter areas

Now that we have the dark areas, we will focus on lighter colours.

Try to look for edges and spots where light would reflect off the surface. I didn’t really select one direction of light source because I like the flatter look of the final prop, but you can absolutely just say that light would hit the sword from the right and paint all highlights in places where they would naturally occur.

Once you figure out where you want your highlights to be, paint them with a mix of white and yellow.

Then outline them with white paint.

Step 6: Edge paint

Now, for the final touch, take a white acrylic marker and outline rough highlight edges that we painted earlier to create a smoother look.
I also recommend using the marker in other areas, not just the highlights, because this will help you create a comic-like look

Step 7: Fixing colours

The last step you can take to ensure your paint stays in place is to spray the whole prop with a transparent coat. For this project, I recommend using velvet clear coat because it gives you the best of both worlds when it comes to mat and shine.

Final Result

And here it is: Ekko’s sword from Arcane, printed, painted, and ready for display or cosplay!
