Sinterit launches the softest TPU used in small SLS 3D printers
At Formnext 2018 Sinterit will show the softest TPU powder dedicated for small SLS 3D printers, called Flexa Soft. With the lowest hardness (measured in Shore A type scale) in this material range, its wide usability is unprecedented.
15 October 2018
Additive manufacturing is typically identified with producing hard and stiff objects. Across different techniques, selective laser sintering (SLS) is mostly known for detailed and high surface quality prints made from PA (polyamides). But what if there was a material so soft and mellow that 3D printing industry experts will not believe it was used in an SLS 3D printer?
Formnext 2018 will be the first opportunity to see the new Flexa Soft by Sinterit. This material from the TPU (thermoplastic polyurethanes) group has exceptional softness, between 40 – 55 in Shore A type scale.
The range of application is extensive. From fashion to medicine – when you need to simulate soft material, Flexa Soft seems to be perfect.
For trial surgeries
In the last few years, based on medical imaging, 3D printing is getting the well-deserved attention of medical researchers, academics and practitioners. For some surgeons, it became the routine to use 3D printed models before the operation. It is easier to exercise the procedure: choose the right surgical tools, plan their path or even perform a trial surgery. When you 3D print an organ from a hard material, it is difficult to cut it with a scalpel. But with Flexa Soft it is much easier.
In the opinion of several medics, this material perfectly imitates the hardness of some tissues. Models made from this powder are excellent to touch and can easily take the desired shape under load or pressure, retaining its geometry when unloaded.
A new direction in fashion
For the fashion industry, it is a game-changing product. Until now, Sinterit was answering the needs of fashion designers with another material called Flexa Black. Now the possibilities are broader, as Flexa Soft can easily adjust to the wearer’s body. And it is not even close to the finish line. During Formnext 2018 Sinterit will launch a few more materials.
Open to new materials
– Our clients are very keen on experimenting with new powders and continually asking us to develop new ones, which will broaden the manufacturing possibilities of both Sinterit Lisa printers – says Konrad Glowacki, one of the co-founders of Sinterit. – We are very open to those inquiries because we are aware that the capabilities of SLS rapid prototyping have not been fully used yet – he adds.
With enhanced elasticity, it is also a great choice to use it for prototyping gaskets or sensory toys. The best way to find out more applications of Flexa Soft is to try it on Lisa or Lisa Pro.
