When the stamp is removed, the ODT in contact with the gold stays stuck to the gold. Thus the pattern from the stamp is transferred to the gold via the ODT "ink." In technology , soft lithography is a family of techniques for fabricating or replicating structures using "elastomeric stamps, molds, and conformable photomasks". [ 1 ]
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
In 1967 Bhutan introduced lenticular 3D postage stamps as one of the many unusual stamp designs of the Bhutan Stamp Agency initiated by American businessman Burt Kerr Todd. [50] [51] Countries like Ajman, Yemen, Manama, Umm Al Qiwain and North Korea released lenticular stamps in the 1970s. Animated lenticular stamps have been issued since the ...
Pad printing (also called tampography) is a printing process that can transfer a 2-D image onto a 3-D object (e.g., a ceramic pottery).This is accomplished using an indirect offset printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate.
A 3d Wilding Overprinted with black bars for use as a training stamp, 1954 or later.. Eighteen values – in 1 ⁄ 2 d increments up to 3d, 1d increments (plus 4 + 1 ⁄ 2 d) up to 1s, 1s 3d and 1s 6d – were issued starting with the 1 + 1 ⁄ 2 d and 2 + 1 ⁄ 2 d on 5 December 1952.
Stamp was used in some arcade hardware in the early 1980s, including Ms. Pac-Man. [5] Movable Object Block, or MOB, was used in MOS Technology's graphics chip literature. Commodore, the main user of MOS chips and the owner of MOS for most of the chip maker's lifetime, instead used the term sprite for the Commodore 64.

A unique benefit of nanoimprint lithography is the ability to pattern 3D structures, such as damascene interconnects and T-gates, in fewer steps than required for conventional lithography. This is achieved by building the T-shape into the protrusion on the template. [ 29 ]
