Co-sintering

A method for making a thin walled, sintered component, comprising:

• creating a plurality of sub-components using binder jetting additive manufacturing, said sub-components comprising a shaped powder preform, including a powder material and a binder;
• the sub-components having an outer surface including one or more protruding portions having one or more bonding faces configured to interface with at least one of the one or more bonding faces of a neighbouring sub-component;
• heating the plurality of sub-components in a first heating step to at least partially sinter the sub-components;
• assembling said sub-components to form an assembly of sub-components, having one or more bonding interfaces where the bonding faces of adjacent sub-components meet,
• heating the assembly of sub-components in a second heating step to bond the sub-components together to form the component.
