3DMart has recently acquired many new samples of Sinterit 3D printers using SLS technology. After seeing the first two articles, the third one is now here! (See previous articles: Part One, Part Two!)
This Sinterit sample is a part of an automotive suspension. To demonstrate various interlocking functions in a single 3D print, a comprehensive structure was specially designed. For example, the rotating disc represents the car wheel:
Here's the structure of an automotive suspension to help you understand. More detailed information can be found via the link below the image.

In short, this Sinterit 3D printed suspension needs to satisfy several physical functions: normal tire rotation (car moving forward and backward), left and right tire rotation (car turning), and shock absorption (reducing road bumps). Due to the orientation of the print, please imagine it rotated 90 degrees when viewing. Based on these functions, in addition to the tire rotation shown above, it must also be able to rotate 180 degrees to control the car's left and right turns.
It also features a shock-absorbing effect with a strong spring force, capable of withstanding significant pressure, which is consistent with actual shock absorption applications:
This Sinterit shock absorption structure consists of two movable support arms connected to the wheels, with a spring in the middle to achieve the shock-absorbing effect. What's special is that both ends of this spring are directly fused with the connection points.
As we mentioned in our previous sharing, since Sinterit uses SLS technology for powder-based 3D printing, no support structures are required. This allows multiple combinable movable components to be printed in one go. (Further reading: Comparison and Summary of 3 Common 3D Printing Technologies)
After 3D printing, the entire powder block is removed and placed in a tray to clear the powder. You can see the object gradually emerging, and the integrated structure is already complete during printing!
The finished Sinterit product has a great feel, and the spring structure has strong rebound force. If you are interested in the machine, you are welcome to schedule an appointment to see the samples in person at our company, or we also offer printing services using original 3D printers, ensuring you get the same quality.
After the Lunar New Year, we will also be launching 3D printing workshops. Many samples will be on display there. Do you want to learn 3D printing technology?
