3DMART recently received many new samples from Sinterit 3D printers using SLS technology. After reading the first two articles, the third part is here! (Read the previous parts here: Part 1, Part 2!)
This Sinterit sample is part of a car suspension. To demonstrate various interlocking functions in a single 3D print, a complex structure was specially designed. For example, the rotating disc represents the car wheel:
To help you understand, here's the structure of a car suspension. For more detailed information, please refer to the link below the image.

In simple terms, this Sinterit 3D-printed suspension needs to fulfill several physical functions: normal tire rotation (car moving forward and backward), left-right tire rotation (car turning), and shock absorption (reducing bumps from the road). Due to the directional nature of the print, please imagine it rotated 90 degrees when viewing. In addition to the tire rotation shown above, it must also be able to rotate 180 degrees to control left and right turns of the car.
It also has a spring-loaded shock absorption effect. The spring's force is strong, capable of withstanding pressure well, matching actual shock absorption applications:
This Sinterit shock-absorbing structure consists of two movable support frames connected to the tires, 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, because Sinterit uses SLS technology for powder-based 3D printing, no support structures are required. This allows multiple combined movable components to be printed in a single run. (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 appearing; the integrated structure is already complete during printing!
The Sinterit finished product has an excellent feel, and the spring structure has strong rebound force. If you are interested in the machine, you are welcome to schedule a visit to our company to see the samples in person. We also offer OEM services using original factory 3D printers, ensuring you get the same quality.
After the Lunar New Year, we will also be launching 3D printing classes. Many samples will also be on display that day. Want to learn 3D printing technology? Want to experience how a 3D printer works? Want to personally verify the high precision of the Ultimaker S5? Don't miss this great opportunity, click here to sign up online! Seats are limited and will be filled on a first-come, first-served basis!
