A process for making a component by depositing a first layer of a fluent porous material, such as a powder, in a confined region and then depositing a binder material to selected regions of the layer of powder material to produce a layer of bonded powder material at the selected regions. Such steps
A process for making a component by depositing a first layer of a fluent porous material, such as a powder, in a confined region and then depositing a binder material to selected regions of the layer of powder material to produce a layer of bonded powder material at the selected regions. Such steps are repeated a selected number of times to produce successive layers of selected regions of bonded powder material so as to form the desired component. The unbonded powder material is then removed. In some cases the component may be further processed as, for example, by heating it to further strengthen the bonding thereof.
A process for making a component comprising the steps of (1) depositing in a confined region a layer of a fluent porous material having interconnected porosity; (2) applying to one or more selected regions of said layer of fluent porous material a further material which will cause said layer of flue
A process for making a component comprising the steps of (1) depositing in a confined region a layer of a fluent porous material having interconnected porosity; (2) applying to one or more selected regions of said layer of fluent porous material a further material which will cause said layer of fluent porous material to become bonded at said one or more selected regions; (3) repeating steps (1) and (2) a selected number of times to produce a selected number of successive layers, said further material causing said successive layers to become bonded to each other; (4) removing fluent porous material which is not at said one or more selected regions to provide the component.
