Abstract: A multidimensional printer makes a multidimensional structure from a liquid composition and includes: an energetic crosslinking particle source; a vacuum chamber that receives energetic crosslinking particles from the energetic crosslinking particle source; a membrane that transmits the energetic crosslinking particles; and a sample chamber that: receives a liquid composition that includes a solvent and polymers, the polymers including a cross-linkable moiety subjected to the energetic crosslinking particles such that portions of the polymers proximate to the cross-linkable moieties subjected to the energetic crosslinking particles crosslink to form a solid crosslinked polymer structure, wherein the membrane isolates a vacuum of the vacuum chamber from vapor of the liquid composition in the sample chamber.

Abstract: A non-vacuum, non-contact spinner wafer chuck including: a basal member including; a fastener receiver that receives a fastener; a chuck collar including: an inner collar wall; and an outer collar wall; and an engagement surface that: receives and engages a wafer; a wafer engagement cam including: an engagement face that engages the wafer; an index cam disposed on the chuck collar and comprising: an index face that faces toward the fastener receiver and that engages the wafer; and a spinner engager disposed on the spinner-side surface of the basal member and comprising: a spinner arm receiver bounded by a wall and that receives a spinner of the wafer processing machine, wherein the wafer engagement cam and the index cam engage the wafer and maintains an orientation of the wafer with respect to the index cam in response to rotation of the wafer relative to the non-vacuum, non-contact spinner wafer chuck.
