A selective inhibition of sintering (SIS) technique may be used to fabricate a three-dimensional (3-D) dense metal object from a binderless metal powder. A number of layers of metal powder are provided on a build tank. For each layer, regions of the layer are sinter-inhibited, e.g., by depositing a sinter-inhibiting material such as a ceramic slurry, a metal salt, or oxidizing metal particles in the powder using chemicals or a concentrated heat source. Each layer may be compacted before the next layer is provided. A final compact may then be sintered. Unwanted sintered sections may be removed from the compact at boundaries formed by the sinter-inhibited (unsintered) regions, and the object extracted.
