Technical case study
Non-contact spraying where contact printing is difficult
Rough, fibrous, or uneven substrates are not always friendly to contact printing. Air spraying can place material without pressing a tool into the surface.
The challenge
A coconut mat or carpet-like material has an uneven surface where contact tools may be unreliable or mechanically awkward.
The setup
The CNC Airbrush follows the programmed shape above the material and deposits color by air spray. The substrate absorbs and scatters the material differently than a smooth plate.
The result
The video shows readable marking on a fibrous mat, demonstrating why non-contact spray application can be useful for rough surfaces.
Why this matters
The same process will not look identical on every substrate. Fiber, absorption, nozzle size, distance, and liquid behavior decide edge softness and coverage.
