An elastomeric mask is provided that allows deposition of a variety of materials through mask openings. The three-dimensional printing processes are useful for making articles from a build material powder, e. Respective contacts in the contact seats are each formed with an abutment arm extending along a wall of the respective contact hole and a spring arm extending into the respective contact hole and elastically deformable from a rest position closely juxtaposed with the respective abutment arm to a holding position spaced therefrom. The extension component can inherit delivery properties from an underlying platform interface associated with the delivery channels in order to mitigate coding and development details involved when utilizing or invoking the platform interface. The detection terminals are all arranged at equal intervals.
