Abstract

Combination of ink-jet printing (IJP) and micro-transfer moulding (µ-TM) micro-fabrication techniques is proposed and demonstrated in this work. First IJP is used to fill the micro-cavities in an elastomeric mould. Then a µ-TM process is done using this mould to transfer the pattern into a substrate. After optimization of the filling parameters, it has been possible to fabricate 60 µm-height test structures without any overflow or residual layer, with gaps of only 25 µm between them. Additionally, it is demonstrated that the proposed method can be used to manufacture heterogeneous structures in one single transfer step, after the deposition of more than one polymer into the mould. These results present the proposed IJP assisted µ-TM as an excellent candidate for the development of complex heterogeneous systems by means of a simple, robust and cost-efficient method.

Inkjet printing

Inkjet printing is a type of computer printing that recreates a by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals.As of 2023, sublimation printers have outsold inkjet printers by nearly a 2:1 ratio, accounting for 9.

3D printing

3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping.

Single transferable vote

The single transferable vote (STV) is a multi-winner electoral system in which each voter casts a single vote in the form of a ranked-choice ballot. Voters have the option to rank candidates, and their vote may be transferred according to alternate preferences if their preferred candidate is eliminated or elected with surplus votes, so that their vote is used to elect someone they prefer over others in the running. STV aims to approach proportional representation based on votes cast in the district where it is used, so that each vote is worth about the same as another.
