    Abstract: The present disclosure is drawn to material sets for 3-dimensional printing, 3-dimensional printing systems, and 3-dimensional printed parts. A material set can include a polyamide polymer powder having an average particle size from 20 μm to 120 μm and a fusing agent. The polyamide-11 can have a solution viscosity from 1.5 to 1.75 at room temperature, and may increase by no more than 5% after exposure to 180°C for 20 hours. The fusing agent can include an energy absorber capable of absorbing electromagnetic radiation to produce heat.

    Abstract: According to an example, build temperature modulation may include determining a characteristic of an object to be produced by three-dimensional printing. The three-dimensional printing may divide the object into a plurality of printing areas for producing the object by using a fusing agent. The build temperature modulation may further include determining, based on the characteristic of the object to be produced by the three-dimensional printing, a fusing agent flux amount of the fusing agent sufficient to oversaturate a printing area of the plurality of printing areas to modulate temperatures related to the plurality of printing areas to a substantially constant temperature across the plurality of printing areas.

    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.

    Abstract: At least one agent distributor may be to selectively deliver coalescing agent onto portions of a layer of build material at a first density and at a second density lower than the first density. A controller may be to control the at least one agent distributor to selectively deliver the coalescing agent at the first and second densities onto respective first and second portions of the layer in respective first and second patterns derived from data representing the three-dimensional object to be generated, so that when energy is applied to the layer the build material may coalesce and solidify to form a slice of the three-dimensional object in accordance with the first pattern. The second portion may be in proximity to a boundary of the first portion. Presence of the coalescing agent in the second portion may be to prevent at least some heat from flowing away from the first portion when the energy is applied.
