In finished devices, hydrophobic membranes are often heat staked to cartridges, requiring custom cutting and staking tooling. To avoid these tooling costs during prototyping, membranes are typically adhered using pressure-sensitive adhesive, which is prone to delamination.

VENTA enables more realistic early-stage testing by bringing the robustness of heat-staked vent assemblies to the prototype phase, where traditional heat staking is generally not feasible on 3D-printed or laser-cut devices.
