Using skin-safe, eco-friendly silicone ensures that every creation aligns with conscious fashion values.
Lynxter Silicone 3D technology gives the material a mysterious delicacy as well as
surprising robustness: a major innovation for the design industry.
Of course, we think of luggage, fashion (both haute couture and ready-to-wear) but not only that…
we also envision applications in the automotive or aerospace industries with personalised seats
or those with better vibration absorption. In the medical field, we already imagine the bandages
of tomorrow, in sports we improve accessories (silicone reinforcements on knee pads to improve
durability and comfort, for example). Let’s not forget the film and entertainment industry with
incredible prospects for creating unique sets and never-before-seen props.
There are numerous applications for printing on textiles, and the possibilities are limitless.
Especially with our S300X ‑ LIQ21 & LIQ11 machine, silicone printing allows for two applications:
Reduce waste and produce only what you need. With silicone 3D printing, you can create designs on-demand, eliminating overproduction and excess inventory. Customise or upcycle garments sustainably by adding new patterns, textures, and details directly onto existing pieces, extending their lifespan. Using skin-safe, eco-friendly silicone ensures that every creation aligns with conscious fashion values.
Soft robotics is a technology that concerns the creation of robots that are almost entirely “soft”: their articulations
and their movements are flexible thanks to the use of soft, elastic, bendable or easily deformable structures and materials.
That’s great, but how did we get here? The field of soft robotics is the natural evolution of robotics. It appeared with the
development of technical silicones and innovative processes such as the 3D printing revolution. These solutions now make it
possible to significantly broaden the variety of robotic motions by integrating mechanical movements of compression, stretching,
unwinding and swelling. Robots therefore possess more flexible and softer motion mechanics; some robots can, for example,
reproduce the undulating and twisting movement of tentacles.
Object manipulation is more precise and controlled, soft robots drastically minimise risks of danger and damage to the surrounding environment during intervention. This solution is perfectly suited to interaction with unstable or uncertain environments as well as for handling fragile objects in the food, space or medical robotics sectors, for example:
The part in question is a boot seal for a brake system – used to protect the system from water, dust, oil and ballast.
It is not a very exposed part and needs to be made of a really flexible material: silicone is therefore ideal.
Silicone additive manufacturing appears to be an ideal alternative to address this one-off and urgent need.
How then to move from a molded part to a printed part?
A key advantage of this partnership lies in the customisation of grippers. Lynxter’s expertise in silicone
3D printing allows for tailor-made solutions that meet the specific needs of Niryo’s clients. Whether for
R&D projects, handling delicate components, food products, or industrial parts, the grippers can be
adjusted in shape, texture, rigidity, colour, and size.
This innovative approach enables rapid and easy integration onto robots, offering a true plug-and-play
experience that minimises setup time and costs. Traditional methods require extensive resources to design
silicone parts for robotics, including mold creation and material casting. Moreover, conventional molding
techniques struggle to accommodate the intricate designs of grippers, which often feature internal channels,
cavities, and flexible deformation angles. Only liquid IDEX 3D printing can achieve such complexity with efficiency.
Thanks to its flexibility with materials, Lynxter supports the rapid design and print cycles needed to create ergonomic devices—like personalised camera grips for users with disabilities or silicone orthopedic collars. This allows fast iteration and customisation to user anatomy, noticeably improving comfort and usability.
Plasma spraying is a surface treatment process providing a solution to deposit a coating on all
or specific areas of a part. The deposited coating brings new functionalities to the surface and
improves its physical, chemical or tribological properties.
This technique is based on the creation of an electric arc in a mixture of “plasma gas”.
The plasma, whose temperature can reach 16,000°C, is used to melt a powder stream as it passes
through the torch.
Different plasma gases are used such as argon, helium, nitrogen, or hydrogen. The gas mixture and
the projection conditions can be adjusted to modify the thermal properties of the plasma as well
as the speed of the particles.
The powder flow used depends on the material to be deposited. It can be metals, metal alloys,
carbides, oxides, … whose composition and particle size are finely controlled. This one is
propelled by a carrier gas in order to be injected in the plasma gas mixture.
Plasma spraying is carried out under atmospheric pressure and is used to reinforce parts intended
to be used in extreme conditions.
Faster lead time: Silicone 3D printing enables the creation of masks tailored to specific applications,
ensuring optimal performance in various geometries and treatment scenarios.
Improved compliance indicators: The flexibility of silicone 3D printed masks ensures superior sealing,
preventing leaks and optimizing the efficacy of wet surface treatment.
Improved staff workflow: Silicone masks are easily removed, cleaned, and disinfected, saving time,
promoting hygiene and suitability for repeated use.
Gain in flexibility: Silicone’s resistance to various chemicals enhances the durability of the mask,
making it apt for a diverse range of wet surface treatments.
Post-treatment is one of the final steps in the manufacturing process of a part. In industry,
it consists of carrying out one or more operations to finalise the surface condition of a part: the objective
is to improve the appearance or function of the surface to adapt it to the requirements of specific uses.
Many of these operations are grouped in the “surface treatments” family. Industrial reconditioning companies
or surface treatment specialists use these processes every day. Surface treatment processes are an important
and advantageous step in the manufacturing cycle of a product for many sectors such as aeronautics, chemicals,
energy, electronics and medical.
Within these sectors, different categories of post-treatment can be distinguished. Mechanical, chemical, and
thermal post-treatment, finishing (paint, varnish, etc.). In aeronautics a machined aluminum part may undergo
the following treatments: degreasing > shot blasting > dye penetrant testing (non-destructive testing)
> OAC – chromic anodic oxidation > primer > finishing.
Ligier Automotive used silicone 3D printing to prototype transmission bellows, avoiding costly molding
for small production runs while testing performance under extreme conditions like high temperatures,
speeds, and exposure to grease.
An alternative to producing a molded part, which requires specific tools and is not cost-effective for single or very small series production.
With a printing time of 3 hours 50 minutes per part, and rapid CAD design modifications (thickness), 2 business days are sufficient to
finalise the part’s development.
Tests were conducted on the manufacturer’s Ligier JS2 R development car. These initial tests were particularly positive as the bellows responded
perfectly: resistance to temperature, behavior at high speed: no deformation, no grease ejection. The technology thus appears compatible with
these significant technical constraints and could offer an interesting solution for prototyping and small series of bellows of all types.
Faced with a supply shortage, a railway company used Lynxter’s silicone 3D printing to rapidly produce
a critical brake system seal, cutting lead time from weeks to days and showcasing the speed and flexibility
of additive manufacturing in emergency situations.
The company needed to change a faulty part on one of its trains. However, this part is out of stock. The
part is traditionally produced using injection molding and typically requires a manufacturing lead time of
several months; a delay that the company could not anticipate due to the unforeseen nature of the incident.
When this particular part is damaged or missing, the train may be immobilised, resulting in significant
financial loss for the company.
The deadlock situation was therefore resolved rapidly thanks to additive manufacturing along with a quick
modification of the original CAD. This maintenance operation, that would have taken many weeks to resolve
with the classic supply chain, was successfully dealt with in just days thanks to the S600D.
