Repeated coating is often a fixture and path problem
Many lab workflows are not about one large object. They are about repeated coupons, arrays, samples, and comparison tests where the same path logic should be used again and again.
The challenge
Small samples are easy to spray once by hand, but hard to compare when each pass uses slightly different speed, distance, or overlap.
The setup
The machine follows a defined path over the sample area. The real application would usually add a simple fixture or repeatable placement method.
The result
The video shows the principle of repeatable CNC-controlled spraying on multiple small targets, useful for experiments and comparison workflows.
Why this matters
For R&D teams, the value is often not speed alone. It is the ability to keep motion and deposition settings stable while changing only the material or process parameter being tested.
