The mounting arrangementis configured to permit displacement of the build platformin a vertical or Z direction whilst permitting unconstrained thermal expansion and contraction of the build platform in the horizontal or X-Y plane. The guide elementsabut against adjacent sides of the build platformto inhibit angular displacement about a vertical axis and permit unconstrained thermal expansion and contraction in the X-Y plane.
