Abstract: Certain examples described herein control an amount of a functional agent that is deposited in a three-dimensional printing system. In certain examples, an amount of a functional agent is controlled based on a distance function, wherein the distance function is associated with a distance between a particular portion of an object to be fabricated and a surface of the object. The functional agent may be a binder, a fusing agent or a detailing agent, amongst others.

Abstract: The present disclosure is drawn to material sets and 3-dimensional printing systems that include a fusing agent. One example of a material set can include a detailing agent including water; a splash reducing compound comprising an infrared-absorbing dye, a polymeric binder, or combination thereof; and a water-soluble co-solvent. The material set can further include a fusing agent including water and an energy absorber.

Abstract: According to an example, a three-dimensional (3D) printer may include a first delivery device to selectively deposit first liquid droplets onto a layer of build materials and a second delivery device to selectively deposit second liquid droplets onto the layer of build materials, in which the second delivery device is positioned in relatively close proximity to the first delivery device. The 3D printer may also include a controller to identify a density at which the second liquid droplets are to be selectively deposited to control splashing of the build materials upon which the second liquid droplets are deposited and to control the second delivery device to selectively deposit the second liquid droplets at the identified density.
