3D printing materials are one of the most important parts for the technology development. Every application field has its own material, depending on the results quality and features. It’s all about filament.
Companies and professionals are looking for reliable, easy to print materials that can be used to print test-objects. To supply these needs, Sharebot developed a special, unique filament with mechanical resistance: Nylon-Carbon.
Nylon-Carbon is a composed material made with nylon and carbon. Printed models are black and slightly rough, very easy to work with in post-production (as we’ll see later). Technical features are unique: it’s easy to print (240°C extrusion temperature, 30° plate temperature without having to apply any special spray to secure it), resistant like nylon and light, rigid and stable during the printing process.
One of the main features is the ability to resist when twisted, making it the perfect material to print mechanical object able to weight a big pressure. In the picture above it’s possibile to see the half of a big fan printed with Sharebot XXL. Nylon-Carbon can realize a functional and functioning prototype that can be tested even in stress situation like a traditional injection molded model. This particular turbine is almost impossible to print without 3D printing because of the unique design.
Heat resistance test
What kind of heat resistance do Nylon-Carbon has?”. It is a common question when speaking about this filament. Our R&D deparment researchers tried to give an answer testing the material in a particolar situation: heating it at 160°C.
They printed a mechanical system composed by a cylinder and a rotor (printed separately then assembled together). The structure is used to be realized with metal but, as we told before, Nylon-Carbon can resemple the same mechanical features.
Once tested the mechanical resistance (the rotor wheels inside the cylinder without problems), our researchers started to heat it externaly at 160°C (the inner temperature reached a temperature between 90° and 100°). During the entire experiment the rotor continued to spin and it wasn’t affected at all.
The picture above shows both the cylinder and the rotor after being heated. You can see there’s no damage: no warping and the mechanics resistance isn’t affected. If the objects were damaged, the rotor could not rotate, proving the highest material heat resistance.
These two cases can help to understand the importance that Nylon-Carbon can have as a rapid prototyping material in every workflow.
