Problems solved by technology

In the latter case, the complexity of the part increases and the performance of the part can be sacrificed to accommodate the overhang
Regardless of the approach, current processes for protecting openings in the surface of a part can be challenging because individually forming and / or removing a protective mask can be very complex

Embodiment Construction

[0020] As an initial matter, in order to clearly describe the current technology, it will be necessary to select certain terms when referencing and describing related components. To the extent possible, common industry terminology will be used and adopted in a manner consistent with the term's accepted meaning. Unless otherwise indicated, such terms should be given the broadest interpretation consistent with the context of the present application and the scope of the appended claims. Those of ordinary skill in the art will appreciate that several different or overlapping terms may often be used to refer to a particular component. An object that may be described herein as a single part may comprise multiple components and be referred to in another context as consisting of multiple components. Alternatively, an object that may be described herein as comprising multiple components may be referred to elsewhere as a single part. Several descriptive terms are used regularly herein...

Abstract

The invention relates to a protective mask manufactured by two material additive manufacturing and a related method. The protective mask (100) for a part (102), the part (102) including a plurality of openings (104) in a surface (106) thereof, is provided. The protective mask (100) includes a mounting member (120) at least partially within each of at least two of the plurality of openings (104). Each mounting member (120) includes a water soluble material (160). A masking member (130) couples the at least two mounting members (120). The masking member (130) includes a non-water soluble material (162). Each mounting member (120) includes a first plurality of integral layers of the water soluble material (160), and the masking member (130) includes a second plurality of integral layers of the non-water soluble material (162). The protective mask (100) can be made by a two material additive manufacturing system (150). A related method is also provided.

Description

Background technique [0001] The present disclosure relates generally to part manufacturing, and more particularly to a protective mask for covering openings in a surface of a part. The protective mask consists of two components, one of which is made of a water-soluble material. Both components are formed by additive manufacturing. [0002] Industrial parts may be exposed to a variety of processes after fabrication to complete the part. In one example, a part may be exposed to shot peening, in which the surface of the part is bombarded with a peening material, such as metal shot. In another example, a part may be coated with a protective layer to protect the underlying material from the harsh environment in which the part will be used. For example, a thermal barrier coating (TBC) may be applied to the outer surface of a turbine rotor blade to protect the blade from high temperatures during use. [0003] Some parts may include openings in their surfaces that need to be prote...
