Answer

Brief Explanations:

The lost - wax casting technique involves first creating a wax model of the object. Then, a heat - resistant material is placed around the wax model to form a mold. The wax is then melted and drained out (the "lost" part), leaving a cavity in the mold. Molten metal or other material is then poured into the cavity to create the final object. Among the options, "A heat - resistant material is placed around the printed object to create a mold" best describes a key step in the lost - wax casting process.

Answer:

A heat - resistant material is placed around the printed object to create a mold.
