3DMart once shared a beginner's guide to three technologies (further reading: A Comprehensive Guide to 3 Common 3D Printing Technologies). You already know that Sinterit's SLS laser powder sintering technology doesn't require support material, making it suitable for complex hollow and mechanical structures. This time, we'll be sharing Sinterit's latest 3D printed samples. Let's first take a look at its dynamic performance:
This SLS movable 3D printed gripper, somewhat resembling an alien creature, combines only two parts: a rigid structure and soft tips.
The rigid structure is printed with PA12 powder, resulting in a product that is rigid with good mechanical strength and heat resistance. The soft tips use Flexa Black elastic black powder, which is a TPU polymer, elastic, and chemically resistant. Besides industrial mechanical structures, it also has applications in the fashion industry. (Further reading: 3D Printed Fashion Adorns Miss South Africa)
As seen in the image, the movable structure consists of a central spring, dual-side press buttons, and a closed pull ring. Pressing the buttons activates the internal spring, causing the gripper tips to open and close.
Thanks to the support-free forming method of SLS 3D printing technology, these objects can be integrally formed in a single 3D print, meaning enclosed parts require no gluing or additional assembly.
We additionally printed a central spring to demonstrate the material properties and toughness of the central spring structure. It requires significant force to press and has excellent rebound.
We also took close-up shots of the sample details so you can see that Sinterit prints typically don't have obvious layer lines, but rather a matte or frosted surface texture.
Sinterit's latest 3D printed samples were already showcased at the last sharing session (further reading: 3D Printing Technology Sharing Session, Learn Tons of Knowledge!). For those who couldn't register last time, you are welcome to call and schedule an appointment to view the samples or consult about more application areas for Sinterit printers.
