The Olympic rings are the globally recognized symbol of the Olympic Games. They consist of five intertwined rings of equal size, colored from left to right: blue, yellow, black, green, and red.
The rings symbolize the unity of the five continents and the meeting of athletes from all over the world at the Olympic Games. Contrary to popular misconception, the colors of the rings do not correspond to specific continents. Instead, the combination of the five colors with the white background represents the colors of the national flags of all the countries at the time the symbol was created.
The Olympic rings were first introduced by Pierre de Coubertin in 1913 and have since become a powerful representation of the Olympic Movement and its values.
We 3D Printed Olympic Rings
● Process: SLA
● Material: High-quality resin
● Post-processing: Fine sanding and painting
The Olympic rings are the symbol of the Olympic Games, so we had to make the 3D printed replicas for this Olympic season. We started with a 3D design, and we chose not to 3D print the Olympic rings in one piece because we wanted the interlocking structure to represent the spirit of unity and harmony.
SLA and high-quality resin were used to make the five rings, each with a different interlocking assembly structure. The rings were then support removed, fine sanded, and spray painted to achieve the effect. Here are the final rings we made:
3D Printed Raw Parts
Here’s the 3D printed red ring without any post-processing; you can see it still has the supports on it:
And the layer lines are visible too:
Supports Removing
Once the print is complete, the next step is to remove the supports. We use breakaway supports in our SLA printing process to allow for easy removal of support structures and reduce build chamber space usage.
Sanding
Sanding is the next step. This process smooths the surface of each ring, removing any imperfections left after the supports have been removed. It is a laborious process that transforms the rough texture into a smooth surface for final display. Not only does sanding enhance the visual appeal of the rings, it also prepares them for the next stage - spray painting. The sanding process begins with coarse sandpaper to remove larger imperfections, then uses finer grits to achieve a smooth surface.
Spray Painting
Spray painting in 3D printing is one of the most popular post-processing techniques used to enhance the appearance of printed objects. It involves applying paint to the surface of a 3D printed part to add color, improve the surface finish, and sometimes protect the part.
The goal of spray painting is to achieve a smooth, uniform surface that hides the layer lines of 3D printed objects, giving them a more professional, high-quality, and aesthetic appearance.
In our 3D printed Olympic rings example, we used gloss paint. Gloss paint provides a high gloss. It has a reflective sheen similar to a mirror. So you can see the stunning and shiny rings:
However, using gloss paint has challenges because any deviation will impair the visual appeal and make the surface susceptible to scratches. It is critical to apply gloss paint evenly to maintain its aesthetic appeal and minimize the risk of surface defects.
In addition, gloss paint is widely used to enhance the surface finishes of smart hardware, home appliances, plastic parts, etc.
