Parts that lie in the X-Y plane will be stronger than those aligned on the Z-Axis. If a part has a particularly delicate feature, especially one shaped like a thin rod, align that feature in the X-Y plane for the greatest strength. If a part has particularly delicate features that are supported only by unprinted powder, build a Fixture for the part to reduce the chances of breaking the feature during powder removal.
Do not tightly pack multiple parts into the Build Bed. If multiple parts are tightly packed, it may be difficult to lift them out of the Build Bed with proper support. If a delicate part is being built with other more solid parts, add a Fixture to the delicate part to protect it during powder removal.
