Additive manufacturing compositions include low-absorbing particles or non-absorbing particles that have an absorbance for wavelengths of 300 nm to 700 nm that is equal to or greater than 0 Au and is less 1.0 Au, such as 0.001 Au≤absorbance≤0.7 Au. Slurries including such particles and an uranium-containing particle and that are used in additive manufacturing processes have an increased penetration depth for curative radiation. Removal of low-absorbing particles or non-absorbing particles during post-processing of as-manufactured products results in pores that create porosity in the as-manufactured product that provide a volume accommodating fission gases and/or can enhance wicking of certain heat pipe coolant liquids. Low-absorbing particles or non-absorbing particles can be functionalized for improved properties, for example, with fissionable material for improved ceramic yields, with burnable poisons or stabilizers for increased homogeneity, with stabilizers for localized delivery of the stabilizer, or with combinations thereof.

A preformed thermoplastic polymer is dispersed into a polyol via a mechanical dispersion process. A stabilizer is present to stabilize the dispersed polymer particles. An antisolvent is also present. The antisolvent has been found to lead to smaller particle size and increased dispersion stability.

Described herein is a polar non-aqueous dispersion comprising polar polymeric microparticles in a polar non-aqueous medium, the polar polymeric microparticles being insoluble in the medium and being produced by dispersion polymerization of vinyl monomers such as acrylate monomers in the medium in the presence of a polymeric acrylic stabilizer. Inks, coatings and overprint varnishes are formulated that employ the polar non-aqueous dispersion. Such inks, etc., exhibit superior chemical resistance properties, for example in one-part and two-part systems.
