Based in 2016, Lynxter fabricates modular industrial machine instruments, in addition to 3D printers, because the French firm is working to democratize additive manufacturing. Its first 3D printer, the modular S600D, was launched two years later, and in 2020 Lynxter partnered up with ViscoTec to print silicone onto textiles. Due to its nice chemical and UV ray resistance, silicone may also be used to 3D print prosthetics, and lately, Lynxter determined to work with French silicone producer COP Chimie to make silicone 3D printing out there to the healthcare trade, in addition to enhance its personal vary of silicone supplies which can be appropriate with its S600D system.
Lynxter’s S600D 3D printer could be fitted with silicone cartridges, which make it attainable to deposit high quality, exact strings of the fabric with each the single-component LIQ11 and two-component LIQ21 toolheads. The liquid extrusion LIQ11 toolhead makes use of an industrial volumetric dosing pump to exactly stack traces and liquid dots of silicone, with a producing quantity of Ø390 x 600 mm on the S600D, whereas the LIQ21 includes a volumetric dosing pump as properly, but additionally features a static mixer for homogenous 3D printing.

Now, Lynxter has introduced that the COPSIL 3D silicone materials vary by COP Chimie has been formally accepted to be used on its S600D 3D printer. The supplies on this household allow the manufacturing of sentimental components with difficult designs, in addition to tender components manufactured in small sequence, reminiscent of for prototyping functions.
“The silicone elastomer COPSIL 3D 4025 consists of a two-component system (resin and hardener) which is combined in equal components and cross-links at room temperature by a polyaddition response with a platinum catalyst,” the COP Chimie web site explains.
“Its distinctive consistency and reactivity simplify the design of components via 3D printing.”
The COPSIL 3D 4025 line has a hardness of 40 Shore A, and 3D printing in silicone with this materials household’s two-component RTV 40 ShA silicone on the S600D has been licensed ISO 10993-5 for contact with pores and skin. The 2 corporations 3D printed take a look at tubes on the printer, which efficiently underwent cycotoxity testing with the intention to earn this necessary certification, which assures customers that extended use with the fabric is just not harmful for his or her pores and skin.
In orthopedics and podiatry, orthopedic insoles are thought-about fairly obligatory, and customised ones can be certain that they are going to exactly match a affected person’s distinctive foot form. As with many customized functions, 3D printing is a good way to fabricate insoles and different orthotics, as it may be used to make complicated, made-to-measure merchandise, which regularly price more cash and take extra time to supply if you’re coping with conventional manufacturing processes. As a result of silicone has such excessive elasticity, cushioning, and supportive properties, this can be a good materials for making orthotic insoles, which should be comfy however sturdy sufficient to help the affected person’s physique weight.
3D printing with high quality strings of silicone, now enabled by Lynxter and COP Chimie, can be very useful for healthcare, however most particularly the orthotics sector.
COP Chimie and Lynxter labored collectively to check out their 3D printed silicone orthopedic insoles, in order that they’ll transfer to the following degree and create prototypes with normal modeling methods out of the two-component COPSIL 3D 4025 RTV 40ShA silicone. The testing will validate the usage of 3D printing to create made-to-measure, personalized merchandise, and show that orthopedic insoles could be made extra sturdy, comfy, and hygienic, and carry out even higher and extra effectively.
