Using a multicanonical Metropolis algorithm we have performed Monte Carlo simulations of the 3D 3-state Potts model on L3 lattices with L=20, 30, 40, 50. Covering a range of inverse temperatures from \ensuremathβmin=0 to \ensuremathβmax=0.33 we calculated the infinite volume limit of the entropy density s(\ensuremathβ) with its normalization obtained from s(0)=ln3. At the transition temperature the entropy and energy endpoints in the ordered and disordered phase are estimated employing a novel reweighting procedure. We also evaluate the transition temperature and the order-disorder interface tension. The latter estimate increases when capillary waves are taken into account.
