Inks for 3d printing having high modulus and dispersion stability

Abstract

In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, a composite ink described herein comprises a carrier ink comprising a curable material and a solid powder filler dispersed in the carrier ink. In some cases, the composite ink, in an uncured state, has a highly accelerated life testing (HALT) score of at least 2 when tested at 65° C. for at least 14 days. Additionally, in some embodiments, the composite ink, in an uncured state, has an average loss factor tan δ of less than or equal to 3 or less than or equal to 2 over an angular frequency range of 0.5 to 5 rad/s.
