A powder layer smoothing devices adapted for use with powder-layer three-dimensional printers are described. The smoothing devices include an oscillating smoothing device that includes a leading edge adapted to cut, remove, and redistribute excess powder in a powder layer. A leveling sled follows the leading edge to trowel and compact the powder in the powder layer.
