Frequently asked questions

• What is the typical feature size achievable through dot dispensing?
  • Direct ink writing: ~1-100  µm line widths, depending on nozzle diameter and ink rheology [2].
  • Piezoelectric inkjet: droplet volumes in the picoliter range, feature sizes ~20-60 µm [7].
  • Electrohydrodynamic jetting: sub-micrometer resolution reported in lab setups [8].

• How do I choose between different technologies of dot dispensing?

  It depends on your material and application:

  • Direct ink writing: Ideal for viscous or particle-laden inks, 3D structures, and when mechanical strength after deposition is important
  • Inkjet: Best for high-resolution, low-viscosity inks
  • Electrohydrodynamic: Research-level methods for extremely fine resolution or nozzle-free operation
• What dispensing systems suit high-viscosity fluids?

  High-viscosity fluids (>100  cP) are typically handled by contact-based systems such as auger valves, time-pressure dispensers, or needle-based systems. Unlike inkjet, which is limited to lower viscosity ranges, these apply pressure or mechanical force directly to extrude viscous materials .
