Replacement plastic floats for the inside of pumps, printed in engineering filament and matched to the fuel they will live in.
Material and process
Floats are printed in PA6GF — glass-fibre nylon — on a Bambu Lab X2D. Infill is chosen so the finished float matches the density of the original across checks on micro scales.
Workshop testing
Will density-matched the prints to the original float, then submerged a test piece in diesel for a week, tied to a heavy weight. It still floated properly afterwards.
That result contradicts the common claim — including Bambu’s own guidance — that PA6GF absorbs liquid enough to ruin a part like this. The soak test is why these floats are offered for fuel-wetted service.
Fuel types
Order the diesel-density or petrol-density version. If you are working on another fuel, say so on the order and Will can talk through a match.
