Abstract: A system for manufacturing a three-dimensional article includes a support plate, a powder dispenser, a fusing apparatus, and a controller. The controller is configured to operate various printer components of the system to: (1) dispense a first layer of powder, (2) fuse a first boundary contour that is fused at least through the first layer of powder, (3) dispense a second layer of powder over the first layer of powder, (4) fuse a first infill section that is fused through the first and second layers of powder, (5) dispense a third layer of powder over the second layer of powder, (6) fuse a second boundary contour that is fused through the second and third layers of powder and is fused to the first boundary contour; and (7) continue to operate printer components to complete a fabrication of the three-dimensional article.

The controller is configured to operate various printer components of the system to: (1) dispense a first layer of powder, (2) fuse a first boundary contour and a first infill section at least through the first layer of powder and are laterally separated by an unfused zone of powder, (3) dispense a second layer of powder over the first layer of powder, (4) fuse the unfused zone of powder through the first and second layers of powder to define a first fused connecting zone, (5) dispense a third layer of powder over the second layer of powder, (6) fuse a second boundary contour and a second infill section through the second and third layers of powder.

Abstract: Treatment of a fungal biofilm on implants is via a combination of drugs and/or via the implant pre-treatment with one drug or via the combination of drugs.

Abstract: The invention provides a process of making porous structures or materials, including the colloidal processing (e.g. slip casting, pressure casting, tape casting or electrophoretic deposition) of solid particle emulsions to form a green body that can be directly sintered without a de-binding step.

Abstract: From an environmental, safety and economic perspective water should be the solvent of choice for electrophoretic deposition under industrial circumstances. However, because of the electrolytic decomposition of water, the majority of EPD is carried out in non-aqueous solvents. Approaches of the art for aqueous deposition involve the separation of the reaction and deposition front by means of a membrane, the use of palladium electrodes to absorb the formed hydrogen, addition of chemicals to suppress the electrolysis reaction, or lowering voltages below the threshold for water electrolysis. With the first two solutions, the production of coatings is impractical since the deposit is not formed on the electrode, or the electrode material is not suitable since the substrate is usually prescribed by the application. The use of specialty chemicals is expensive and difficult to control.
