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: SinteritNew Composite Material Print, Highly Flexible Movable Structure!) New samples are here again!
This time, we'll show you more details and structures. Let's start by looking at the dynamic performance:
This sample is a bicycle rear derailleur. With the chain and gears installed, this component will 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 supports or assembly.

Sinterit printed this part using PA12 powder, which is very strong and heat-resistant. What's special is that even though it's not a soft material from the Flexa series, its CAD structural design allows for flexibility. For example, it has a main internal spring, and the spring connection points use closed double-sided buckles directly bolted to the bracket, allowing free rotation with very fast recovery.
Due to the monolithic nature of SLS technology, it's not possible to photograph the interior. The two freely rotating gears do not contain bearings, yet they still rotate smoothly (bearing: a ring-shaped rotating structure, commonly found in fidget spinners).
Another sample is a power drill casing. Previously, we had 3D printed drill casings made with FDM and SLA technologies, and now we've added one for SLS technology. This allows everyone to compare the differences between various 3D printing technologies at exhibitions or our events.
The Sinterit Lisa produces a matte finish, printed with PA12 powder for robustness and durability. For a drill casing, the integrity of the boreholes and the precision of the structure are crucial. We've taken close-up shots to show you the details more clearly.
We will continue to add more 3D printing related content, whether it's knowledge or samples, we can't wait to share them with you. Please keep an eye on our latest news or Facebook page to get first-hand information! If you're interested in learning about the machines, feel free to call us for a consultation; alternatively, we also offer high-quality printing services using original equipment.
