Compact silicone 3D printer for industrial and medical applications, IDEX extrusion system.

3D printing with liquids (LAM) is a quite recent but revolutionary development in the world of addtive manufacturing and the French company Lynxter are at the forefront of it with their smart and compact industrial 3D printing solutions for liquids such as the multimaterial Lynxter S600D (also featuring filament and paste toolheads) as well as printers designed exclusively for liquid additive manufacturing, like the S300X silicone 3D printer.

The advantage of silicone 3D printing

Thanks to their unique and qualified know-how on silicone 3D printing, Lynxter was able to design the S300X silicone printer that allows the user to work with industrial and medical grade silicones such as:

  • RTV2 medical grade silicone (5, 10, 25, 40 Shore A) certified skin contact (ISO 10993-05).
  • Industrial grade RTV2 silicones (45 Shore A -10 Shore D) and polyurethanes (50 to 85 Shore A – 12 to 33 Shore D).

These materials maintain their chemical and mechanical properties, do not age when exposed to UV radiation, do not require heavy post-processing, and, most importantly, are not as costly and time-consuming to use when 3D printed with the S300X silicone printer. The reason is that in traditional manufacturing, liquid materials such as silicone are normally shaped by molding. While rentable for large series, molding proves quite limiting for the manufacturing of smaller series, single objects and parts with complex geometries due to the costs and time associated with mold production.

Furthermore, traditional liquid manufacturing via molding does not allow for the production of non-full parts or weight and hardness optimization. Additive manufacturing with the Lynxter S300X printer is a solution to all those challenges as it allows for the production of custom silicone parts or silicone spare parts on-demand and on-site, with much more freedom in terms of shape and elasticity.

Key features of the S300X printer

The S300X silicone 3D printer is a robust but compact and ergonimic industrial printer characterized by precision, efficiency, safety and ease of use. To meet the needs of the sector it was designed for, the S300X printer was equipped with many automations that reduce the need for user intervention to the minumum. The large capacity cartridges allow printing of large parts or batches in complete autonomy and the auto-levelled build surface is removable and hot-swappable.

The tool heights and nozzle XY offsets are calibrated automatically, and the printer corrects machine geometry and generates supports. Additionally, the S300X silicone printer detects material shortage, and the printing process resumes automatically after a power outage, significantly reducing material waste and user intervention.

Regarding user safety and ease of use, the S300X is equipped with removable double activated carbon HEPA H14 filters, lockable machine access, a quiet heated chamber, customizable firmware, and a standalone touchscreen with a web interface and an intuitive user interface.

To further increase user comfort and agilize the 3D printing process, Lynxter has introduced the HUB, an online platform where the user can access advanced print profiles, guides and tutorials, and an interactive product catalog. This solution goes in line with Lynxter's open ecosystem philosophy which strives to provide the users with open access to 3D printing resources and thus help them save time and work more productively

Dual liquid extrusion with supports

The S300X silicone 3D printer comes with two liquid toolheads thus giving the user two options in terms of extrusion - the LIQ11 single-component toolhead to print supports and the two-component LIQ21 toolhead to print the parts.

The LIQ11 and LIQ21 toolheads

These two toolheads work independently in an IDEX configuration to enable quick and efficient manufacturing of complex silicone parts with the help of water soluble support structures.

The manufacturing possibilies that come with the IDEX system go beyond printing with supports and pave the way to the printing of parts with different physical properties, materials or colors in one single print, without having to worry about cross-contamination, design limitations or time-consuming toolhead changes.

New manufacturing possibilities

Industrial silicone applications

The S300X silicone 3D printer was designed for industrial manufacturing so it can be used with very satisfying results for the production of surface treatment masks and plugs, custom seals and gaskets, emergency repair and maintenance, or soft robotics grippers.

The S300X silicone 3D printer will be a valuable addition to any industrial AM workflow and it will help boost production gains reactivity, manufacturing time and in innovation.

Healthcare silicone applications 

3D printing technologies have proven extremely beneficial in the medical sector thanks to the level of customization and reduced lead times. Silicone 3D printing further contributes to the improvement and simplification of the medical workflow by reducing the number of manual interventions involved in the production of ortheses, prostheses, custom orthopaedic and orthoplastic devices, suture training supports, medical implants for epithetics, etc.

Silicone additive manufacturing makes it easier than ever to produce personalized devices without taking a manual impression or using a mold. Furthermore, 3D printing with silicone allows for the printing of lighter parts with modified mechanical properties (hardness, resistance, damping, anisotropy, etc.) by hollowing the part or varying the infill rates, something that is not achievable with traditional silicone manufacturing methods (molding).

Aerospace silicone applications

Silicone 3D printing in aerospace offers a range of vital applications. It enables rapid prototyping for components like seals and gaskets, facilitating iterative design improvements. This technology also supports the creation of customized parts, ensuring precise fits for specific aerospace systems. Additionally, its use extends to producing heat-resistant materials, soft robotics elements, and molds for complex aerospace components, all contributing to innovation, efficiency, and enhanced functionality within the aerospace industry.

This collaboration highlighted the efficacy of silicone additive manufacturing, enabling tailored solutions for intricate masking needs in aerospace applications.

R&D silicone applications

Apart from medical applications, a very interesting R&D application for silicone 3D printing is in soft robotics. Soft robotics is a natural evolution of robotics that emerged with the development of technical silicones and innovative processes such as 3D printing. Soft robotics involves designing and creating robots using flexible and deformable materials, departing from traditional rigid structures and enabling extended kinetics such as compression, stretching, untwisting, swelling, etc. This imitation of natural organisms' flexibility makes it possible for soft robots to navigate complex environments, interact safely with humans, and perform tasks requiring delicate handling or adaptability.

Pliable 3D printed robots boast attributes like safety, durability, and cost-effectiveness. With the help of 3D printing and printers such as the Lynxter S300X, soft robotics demonstrates significant potential for advancements. Trials in intricate operations, such as microsurgery, highlight their maneuverability in confined spaces and precise drug delivery while minimizing tissue damage. The utility of soft robotics extends to safeguarding fragile ecosystems like coral reefs, emphasizing the importance of gentle movements underwater. The possibility to use a wide variety of flexible materials with specific properties (chemical inertia, electrical insulation, temperature, friction, alimentarity) and 3D print complex structures and internal geometries promises a transformative future in robotics across critical domains, possibly including groundbreaking advancements in self-repair, self-replication, and integrating artificial intelligence.

Customized textiles

Apart from its principal uses in industrial manufacturing and in the medical sector, the Lynxter S300X silicone 3D printer can be successfully used in the fashion and textile industry to functionalize textiles.
