Last time, we shared the latest 3D printed samples from the Sinterit series, using SLS technology. Did you think that was the end? (Further reading: Sinterit New Prints with Composite Materials, Ultra-Flexible Movable Structures!) New samples are here again!
This time, we'll show you more details and structures. Let's start with a look at the dynamic performance:
This sample is a bicycle derailleur. With the chain added, the gears can operate. Due to the spring and rotating structure, it automatically retracts when released.
The structure alone connects four parts, not including the other two gears and the central spring. As always, this can be printed as a single, integrated piece in the Sinterit Lisa, because SLS technology requires no additional support or assembly.

Sinterit used PA12 powder for this print, which is very strong and heat-resistant. What's special is that even though it's not a soft material like the Flexa series, it can still achieve elasticity through CAD structural design. For example, it has a main spring inside, and the spring connection points use double-sided closed buckles that are directly bolted to the bracket and can rotate freely, allowing for very quick retraction.
Because SLS technology prints in one piece, it's impossible to photograph the interior. The two freely rotating gears, though without bearings, still rotate smoothly (bearing: a circular rotating structure, commonly found in fidget spinners).
Another sample is a drill casing. We previously had 3D printed drill casings using FDM and SLA; now we've added one for SLS technology, allowing everyone to compare the differences between various 3D printing technologies at exhibitions or our events.
The Sinterit Lisa produces a matte finish. This is also printed with PA12 powder, making it strong and durable. The most important aspects of a drill casing are the integrity of the holes and the fineness of the structure. We've taken close-up shots of the details so everyone can see them more clearly.
We will continue to add more 3D printing related content. Whether it's knowledge or samples, we can't wait to share it with everyone. Please continue to follow our latest news or Facebook page to get first-hand information! For friends interested in learning about the machines, please feel free to call us for consultation; or we also provide high-quality printing services using the original manufacturer's machines.
