Additively manufacturing a 3d object including a second material

An additive manufacturing device comprising:

• a coater;
• a dispenser;
• a first energy source;
• and
• a controller including a processing resource to execute machine readable instructions stored in a non-transitory medium to:
• form a selectable number first layers of a first material via instructions to:
• coat, via the coater, the first material relative to a receiving surface;
• dispense, via the dispenser, a first fluid agent onto first selected voxels of the coated first material;
• and
• apply the first energy source to cause fusing of the coated first material at the first selected voxels;
• and
• dispense, via the dispenser, a second fluid agent including at least one second material to form a selectable number of second layers of the at least one second material at second selected voxels, which comprise some of the first selected voxels.

A method of additively manufacturing a 3D object comprising:

• forming a selectable number of first layers via:
• coating a first material relative to a receiving surface;
• dispensing, via a first dispenser, a first fluid agent onto first selected voxel locations of the coated first material;
• and
• causing fusing at least the first selected voxel locations;
• and
• forming a structure at each of a selectable number of the first selected voxel locations by dispensing, via the first dispenser, a second fluid agent including an electrically active second material to form a selectable number of second layers of the electrically active second material.
