Drug delivery devices comprising a non-bioabsorbable polymer structure configured to support a composition comprising an active agent. The devices include a plurality of portions fused together and a recess configured to support the composition. At least one of the portions includes an impermeable polymer and at least one other portion includes a rate-limiting water-permeable polymer. The rate-limiting water-permeable polymer allows for transportation of the active agent to an exterior of the device.
