Agent droplet deposition density determinations for porous articles

A method comprising:

• identifying, by a processor, a first porosity level range for a first area of an article formed of build material particles;
• determining, by the processor, a first density level at which an agent is to be deposited as droplets onto a first portion of the build material particles corresponding to the first area of the article, wherein the first density level is to cause the first area of the article to have a porosity level that is within the first porosity level range following sintering of the build material particles;
• and
• storing, by the processor, the determined first density level, wherein the article is to be fabricated using agent droplets deposited at the determined first density level;
• and
• controlling a sintering device to apply heat to the build material particles at a temperature and duration to cause the build material particles to be set with respect to each other while the article is formed to have a porosity level that is within the first porosity level range.

A non-transitory computer-readable data storage medium storing program code executable by a processor to perform processing comprising:

• identifying a first porosity level range for a first area of an article formed of build material particles;
• determining a first density level at which an agent is to be deposited as droplets onto a first portion of the build material particles corresponding to the first area of the article, wherein the first density level is to cause the first area of the article to have a porosity level that is within the first porosity level range following sintering of the build material particles;
• and
• storing the determined first density level, wherein the article is to be fabricated using agent droplets deposited at the determined first density level;
• controlling a fabrication component of a three-dimensional (3D) fabrication system to deposit the droplets of the agent onto a layer of build material particles at the determined first density level;
• and
• controlling a sintering device to apply heat to the build material particles at a temperature and duration to cause the build material particles to be set with respect to each other while the article is formed to have a porosity level that is within the first porosity level range.
