Two-colour Seat badge modelled from a photograph and delivered the next day
Samlin Racing needed a replacement Seat badge for a 24 Hours of Lemons car. With no CAD file available, the logo was photographed, modelled in Fusion 360 and printed as a single two-colour part. The photograph was received on 7 September and the badge was delivered on 8 September.
The requirement
Samlin Racing needed a replacement Seat badge for a car competing in the 24 Hours of Lemons. No drawing or CAD file was available, and the badge was required while the car was being prepared for the event.
Because the part was decorative, lightly loaded and required the following day, the priority was a clean fit and short manufacturing time.
Modelling from the photograph
The logo was photographed square-on and imported into Fusion 360. A known dimension was used to calibrate the photograph before the outline was traced and converted into a three-dimensional model.
The black base and silver letter were created as separate regions within one printable model, with a defined step between the two surfaces.
Manufacture
The badge was printed on a Bambu Lab P1S as a single component using black and silver PLA. The colour change was handled during printing, so no paint, masking or adhesive was required.
PLA was appropriate for this non-structural badge because the part carries no meaningful load and the one-day lead time was important.
PLA suited this specific badge, but it would not be selected automatically for other vehicle parts. Components exposed to high temperature, continuous sunlight or structural loading require a separate material assessment. The application determines the material, even when another polymer is easier to print.
