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.
