FilX LW-PLA Grey Filament or FilX “Wayless” PLA Grey Filamentย is a 3D filament that is used where lightweight 3D printing material is required for structural applications within the limitations of PLA polymer. Typical applications would be hobbyistย RC planes, race cars, wind turbines and boat parts. This filament has been made with PLA polymer, colour pigment and a special foaming additive.
The foaming density of this filament is a result of 2 variables:
- The time the polymer spent in the print head (print speed)
- The temperature of the nozzle.
The best practice for determining your maximum achievable foaming would be done by experimentation with these two variables. For example, slow 40mm/min print speed at 220หC can give the same result as 50mm/min at 250หC. It is important to adjust the printer material flow rate down in the same percentage that wall thickness increases, as foaming increases if you want weight loss of your model.
You can use this formula to adjust the flow rate: Thickness of IDEAL foamed sample ‘Wayless’ * flow rate of UNFOAMED sample ‘Wayless’ / Thickness of UNFOAMED sample ‘Wayless’
