Opportunity:
Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize novel siloxane formulations and methods for 3D printable silicones inks used in direct ink writing (DIW).
Background:
Additive manufacturing technology is a promising venture wherein there have been noted time savings for production, cost savings on materials and time as well as the capability of fabricating parts that have complex architectures not easily achievable by conventional methods. Silicone, already used in numerous products, with its exceptional thermal stability, water & chemical resistance, mechanical flexibility, dielectric properties, and biocompatibility characteristics would be an excellent material for use in additive manufacturing. Using the direct ink write (DIW) process, 3D printing with silicone inks would be ideal for many applications, including advanced material such as soft robotics, biomedical devices, and metamaterials.
However, silicone, an inherently flowable liquid, does require modifications to its physical properties in order for it to be a suitable 3D printing feedstock material. 3D printing silicone ink must exhibit shear-thinning behavior and a transition from a gel to a liquid at high shear rates. In addition, the gelled state must be able to retain its shape well enough support its own weight during printing. The interplay between ink development, post-processing, material properties, and performance is a difficult challenge to overcome.
Description:
LLNL researchers, through careful control over the chemistry, network formation, and crosslink density of the ink formulations as well as introduction of selected additives, have been successful in preparing 3D printable si... - Documents:
