Carbon’s SIL 30 silicone material is a proprietary 3D printing material engineered with Carbon’s Digital Light Synthesis (DLS) technology. SIL 30 is a biocompatible material with high elongation and tear strength, making it an ideal option for medical and dental applications. It has a Shore A hardness of 30, which means it has a soft and flexible texture similar to rubber. This material also exhibits excellent printability, allowing for the quickly creation of highly detailed and complex structures. SIL 30 is resistant to standard sterilization methods like EtO gas and gamma irradiation, making it ideal for medical devices that require sterilization before use. Additionally, Carbon’s SIL 30 is translucent, which allows for easy visualization of internal structures and monitoring of fluid flow.
Digital Light Processing (DLP) is a type of 3D printing that employs a UV-sensitive liquid resin cured through a digital light projector. Once the printing process is finished, our AM technicians thoroughly clean the part, remove any supports, and apply UV and thermal curing, if necessary.
DLP 3D printing is an ideal choice for projects that require high levels of detail and finishing in various production-grade materials. This technology can produce components with varying durometers and characteristics, ranging from supple silicone to rigid high-temp cyanate ester. It is beneficial for creating small end-use components, lightweight metal part replacements, functional, high-detail prototypes, jigs, and fixtures.
