Additively-Manufactured Device and Method

A method of manufacturing a device, the method comprising:

• forming a first layer of the device by executing a line melting process to form first grains, wherein:
• the first grains have a first size, and
• the first grains define a portion of an outer portion of the device;
• and
• forming a second layer of the device by executing:
• the line melting process to form additional first grains, and
• a point melting process to form second grains, wherein:
• the second grains have a second size that is smaller than the first size,
• the second grains define at least a portion of an inner portion of the device,
• the additional first grains define an additional portion of the outer portion, and
• the outer portion is disposed around the inner portion.
