Abstract
Apparatuses and systems comprising an additive manufacturing device and an associated terahertz inspection device for inspecting additively deposited layers in real time during or immediately following material deposition and parts made and inspected by the apparatuses and systems and their associated methods are disclosed herein.
Claims20
An apparatus comprising:
- an additive manufacturing device comprising a material deposition head;
- and
- a terahertz inspection device located proximate to the material deposition head;
- said terahertz inspection device comprising a terahertz probe, said terahertz probe comprising a thermal shield substantially enveloping the terahertz probe.
1 more element
A system comprising:
- a housing;
- an additive manufacturing device comprising a material deposition head, said material deposition head located within the housing, said material deposition head configured to deposit a plurality of material layers to form a part;
- and
- a terahertz inspection device located within the housing and further located proximate to the additive manufacturing device, said terahertz inspection device comprising a thermal shield substantially enveloping the terahertz inspection device.
1 more element
A method for additively manufacturing an additively manufactured part, the method comprising:
- individually depositing a plurality of material layers from a material deposition head of an additive manufacturing device to form the part, and non-destructively inspecting at least one material layer using terahertz energy, and further comprising:
- directing terahertz energy from a terahertz inspection device to a location on or within the at least one material layer;
- receiving terahertz energy from the at least one material layer;
- and
- detecting characteristics of the at least one material layer.
