A supplier of development and manufacturing services to medical device OEMs used Freeform Injection Molding from Nexa3D to accelerate time-to-market and slash prototyping costs for a complex silicone-based IV device. SPT Vilecon explained the process in a recent press release.
Certified to ISO 13485, Denmark-based SPT Vilecon describes itself as a fully integrated provider of development and manufacturing services to the medical device industry. It offers in-house tool making and injection molding along with other manufacturing services to companies in northern Europe.
SPT implemented Nexa3D’s Freeform Injection Molding (FIM) technology to help customers shorten time-to-market on complex medical devices in demanding medical-grade materials and to expand on the range of materials that can be quickly and reliably used in prototyping and early device test manufacturing.
The patented FIM process uses high-speed Nexa3D printers and xMOLD resin to print injection molding tools that are compatible with thousands of off-the-shelf injection molding materials, including reinforced high-performance feedstocks. The process reduces design, iteration, and validation cycles using end-product materials to a matter of hours rather than weeks.
Medical device manufacturers are tasked with developing elaborate test protocols to ensure that the product in development is safe and meets essential requirements. If these tests are conducted late in the development process, the more onerous and risky they become. SPT Vilecon often works with silicone, a material that is extensively used in medical applications because of its chemical resistance, mechanical performance, and biocompatibility. However, silicone parts are notoriously difficult to prototype and test, since most grades need to be injection molded to achieve their full performance potential, said the company. FIM enabled SPT Vilecon to offer an alternative to a customer developing an intravenous (IV) silicone product — the use of 3D-printed tooling to perform early design and material verification at a fraction of the cost of conventional methods.
The use of 3D-printed xMOLD tooling provided the following benefits, according to SPT Vilecon:
Robust and valid prototyping and verification are key to minimizing cost, time, and risk factors in developing medical devices, said SPI Vilecon. FIM is a new toolbox for medical device companies seeking to accelerate their innovation and obtain early verification of part performance and moldability, added the company.
SPT Vilecon said it has begun expanding the range of injection mold prototyping with silicone, metal, and ceramic materials to provide medical device manufacturers with an even wider selection of product development and verification services.
