Abstract

A photocurable composition for stereolithographic three-dimensional printing, wherein the photocurable composition comprises a photoreactive oligomer component comprising a hydrophobic oligomer comprising a photoreactive end group, a photoreactive monomer component comprising a photoreactive monomer having a photoreactive end group, and a photoinitiation composition comprising a photoinitiator; the photocurable composition has a viscosity of 250 to 10,000 centipoise at 22° C., determined using a Brookfield viscometer; and the photocured composition has a dielectric loss of less than 0.010, preferably less than 0.008, more preferably less than 0.006, most preferably less than 0.004, each determined by split-post dielectric resonator testing at 10 gigahertz at 23° C.
