Abstract
A process for making a component by depositing a first layer of a powder material 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.
Claims21
A system for making a component comprising
- means for depositing a selected number of successive layers of a porous material;
- means for applying to one or more selected regions of each successive layer of porous material a further material which will cause the porous material to become bonded at said one or more selected regions, said applying means applying said further material after each successive layer of porous material has been deposited to form said component;
- and
- means for removing porous material which is not at said one or more selected regions.
