1. A method of making a three-dimensional object from a solidifiable material, comprising:

  • first traversing a linear solidification device and a blade along a first travel direction along a travel axis while the linear solidification device scans solidification energy onto an exposed surface of the solidifiable material along a scanning axis, wherein during the first traversing step, the blade remains spaced apart from the linear solidification device by a fixed distance in a first blade spacing direction along the travel axis;

    second traversing the linear solidification device and the blade along a second travel direction along the travel axis, wherein during the second traversing step, the blade remains fixed apart from the linear solidification device by the fixed distance in a second blade spacing direction along the travel axis, wherein the second blade spacing direction is opposite the first blade spacing direction; and

    traversing the linear solidification device along the travel axis relative to the blade.
