7-30. (canceled)
35-38. (canceled)
An apparatus comprising:
- a first portion with a base having a first set of tetrahedral and inclined pyramidal protrusions formed thereon, and a second portion with a base having a second set of tetrahedral and inclined pyramidal protrusions formed thereon,
- wherein the first and second sets of tetrahedral and inclined pyramidal protrusions are complementary and positioned proximate one another, forming a lattice-shaped void therebetween, and
- wherein the inclined pyramidal protrusions comprise a rectangular first surface portion and triangular second, third and fourth surface portions.

A method of making a component, comprising:
- obtaining a mold comprising a first portion with a base having a first set of tetrahedral and inclined pyramidal protrusions formed thereon, and a second portion with a base having a second set of tetrahedral and inclined pyramidal protrusions formed thereon, the first and second sets of tetrahedral and inclined pyramidal protrusions being complementary and when positioned proximate one another, forming a lattice-shaped void therebetween,
- filling the mold with a liquid or molten moldable material,
- allowing the moldable material to solidify to form the component, and
- removing the component from the mold.
