An improved apparatus and method provide conditioning to a powder deposited on a substrate (e.g., a web), for example, by wetting the powder in a 3D printing apparatus. To achieve this in an exemplary implementation, a wetting apparatus is located between a powder dispenser and at least one top calendering roller in a direction of movement of the substrate, wherein the wetting apparatus is configured to apply a wetting agent to the powder on the substrate before the powder passes through the calendering roller. The wetting agent is comprised of a material which increases cohesiveness of the powder to prevent the powder from adhering to the top roller. In a particular implementation, the wetting agent is steam confined to an area of the substrate where the powder passes through the wetting apparatus, without wetting other areas of the substrate which are not in the wetting apparatus.

A multi-beam laser processing system comprising a plurality of laser beams and a plurality of pairs of selectively rotatable mirrors for laser beam steering where each laser beam is independently steered by one pair of selectively rotatable mirrors. The plurality of pairs of mirrors are positioned adjacent to one another within a single main body. The main body is positioned directly opposing the beams, the mirrors directing each laser beam simultaneously to a selected location on a substrate. The main body comprises a plurality of vents; a plurality of passages; a plurality of openings; and a plurality of galvos nested densely within the main body. The galvos direct multiple laser beams to a substrate wherein the fields of view overlap and the laser beam focal point remains small and precise.

The present invention includes methods for treating laser-processed materials having an odor generated during the laser processing. The present method includes treating the laser-processed materials with heat to dissipate the odor from the material. The laser processed material may be secured to avoid curling during the heating process. The method can also include a cooling step after heating of the laser-processed material. Multiple cycles of heating and cooling may also be performed to substantially reduce or eliminate the odor from the laser-processed material. The invention also includes articles made according to the method and apparatus for producing laser processed materials having substantially reduced odor.

A watercraft propulsion system for moving a watercraft along a waterway having a bottom and a surface, wherein the watercraft presents a port side and a starboard side. The watercraft propulsion system comprises a boom assembly having a proximal end and a distal end, with the proximal end being rotatably coupled with the watercraft. The watercraft additionally comprises a wheel mounted to the distal end of the boom. The wheel includes at least one generally radially-extending blade assembly, with the blade assembly comprising a primary blade and a secondary blade. The secondary blade extends at an angle with respect to the primary blade so as to present a fluid channel between the primary blade and the secondary blade.

A cutterhead for dredging water-bed material from a body of water. The cutterhead comprises a shroud presenting a front margin for receiving water-bed material into an interior space of the shroud. The shroud additionally includes a port from which water-bed material can be removed from the interior space of the shroud. The cutterhead additionally comprises a rotatable cutterbar at least partially received within the interior space of the shroud. The cutterhead further comprises a debris guard positioned between the cutterbar and the port. The debris guard is operable to filter the water-bed material removed from the shroud through the port. At least a portion of the debris guard that faces the cutterbar includes a concave shape.

A cutterhead for dredging a body of water. The cutterhead comprising a shroud including a top wall, a bottom wall, and two sidewalls each extending between the top and bottom walls. The cutterhead additionally comprises a rotatable cutterbar at least partially received within an interior space presented by the shroud, a first water-jet bar extending along a portion of the top wall of the shroud, and a second water-jet bar extending along at least a portion of one of the two sidewalls. The cutterbar and the water-jet bars are configured to generate a slurry of fluidized material from the water-bed.
