Lynxter takes silicone 3D printing to the next level with the “simplified, affordable and open” S300X

0

French manufacturer of Lynxter 3D printers announced the launch of a new material extrusion system (MEX/FFF), the Lynxter S300X.

Building on the expertise gained during the development of the Lynxter S600D, the company’s latest machine is designed to enable reliable 3D printing of custom masking parts. With its open philosophy, the unit is capable of processing industrial and medical grade silicones and polyurethanes, which is why Lynxter claims it is ideal for creating shock absorbers, gaskets, contact-ready orthoses with skin, functionalized textiles and surface treatment masking devices.

Lynxter Open Materials Portfolio

Based in Bayonne, Lynxter has spent the past six years expanding its MEX/FFF 3D printing offering and now operates in nine countries, in the medical, industrial and rapid prototyping markets. While the company started with a pilot project alongside Airbus, it has since launched a range of open-material S600D 3D printers, supporting them with accessories, in the form of different tool heads.

The S600D itself features a 390mm x 600mm build volume and wide tool head compatibility, allowing users to chop and change to suit their individual application. Lynxter’s FIL11 single extrusion tool head, for example, allows the deposition of materials such as PP, PEKK, PETG and PA6 carbon fiber, while the LIQ21 dual extrusion can process certain RTV2 liquid silicones, and PAS11 is compatible with clay and porcelain.

In addition to being modular, the machine also facilitates quick change of tool head thanks to its quick connectors for electrical wiring and liquid cooling. This allows users to change nozzles in minutes and gives them the flexibility to switch prints with liquid, thermoplastic, or paste-based filaments whenever the need arises.

The new S300X IDEX 3D printer

Designed to meet the end-production needs of businesses, the S300X features a one-piece LIQ11 tool head and a two-component LIQ21 tool head. This Independent Dual Extruder (IDEX) configuration allows users to create complex parts with soluble supports. The S300X also enables the production of unique multi-material parts, which combine different physical properties on a single print.

Along with its new machine, Lynxter also launched “HUB”, an online platform designed from the ground up to help users save time and work more efficiently. In practice, the site allows users to achieve this through the use of advanced printing profiles, as well as access to features such as an interactive product catalog, as well as guides and tutorials. thorough.

According to Lynxter, the system is a “simplified, affordable and open” industrial tool that “prints at high speed while maintaining a superior level of precision”. Since the S300X is also compact and emits very little noise, while running on high-capacity cartridges, it’s also easy to fit into workspaces and doesn’t require constant monitoring.

Target silicone manufacturing

One of the primary target markets for Lynxter’s S300X is the industrial and medical parts manufacturing space. With this in mind, the company views its machine’s compatibility with materials such as RTV2 silicones and polyurethanes as an important feather in its cap, due to their application in these areas, and ISO 10993-05 certification of the first one.

Another advantage is that age-resistant RTV2 silicones also do not require heavy post-processing, and they have mechanical properties at the level of injection molding. Lynxter has also launched its own line of proprietary materials with the system, including an SIL001 silicone, which is claimed to provide users with “industrial grade” results.

Ultimately, the company believes the S300X will “democratize silicone printing”, allowing custom devices to be produced quickly without taking a hand impression or using a mould. In doing so, the machine allows recesses and varying fill rates to also change the properties of the parts, whether to reduce hardness, add strength and improve damping or change their anisotropy.
