> ## Supports

> Your 3-D printer places supports under downward-facing surfaces. Supports are built using the support material, a wax you can easily melt and remove during part finishing. The Preview window can display the surfaces that will have supports attached to them. See Part Viewing Options.

> NOTE: Vertical Columns are the only BuildStyle available for InVision HR printers. See BuildStyle under Default Job Options Dialog Box.
