Abstract: A 3D printer and methods for hot air welding of 3D printed items within a printing operation of the 3D printer are disclosed. These methods allow for a controlled weld between either similar or dissimilar (miscible or immiscible) 3D printed materials with hot air heated from jets near the printer head or heads.

Abstract: Thermal insulation blankets and methods of using the same to repair articles, such as components of turbine engines are disclosed. The thermal insulation blankets are a multilayer composite material that includes: a first flexible fiberglass fabric layer having two sides that are coated with a coating that covers the fiberglass fibers; an intermediate second fiberglass insulation blanket layer made of continuous glass fibers; and a third layer of flexible heat reflective material. The method involves wrapping a component, such as a component of a turbine engine, with one or more thermal insulation blankets in order to retain heat within the confines of a prescribed area for installing or removing parts with a precision fitment. The blankets allow enough heat to induce even thermal expansion of the components.
