What is the surface quality and can I make it smoother?
The finish surface quality depends on the geometry and layer thickness you are printing with. For example the 0.125mm layer thickness will result in a smoother surface compared with the 0.25mm layer thickness, however it will take longer to print.
All BFB printed plastic parts can be sanded (ABS and PLA material). This makes the part smoother, however may change the aesthetic properties due to micro-fatiguing mechanics e.g. colour change.
Application of methyl ethyl ketone (MEK), either by dipping or lightly painting, will smooth the ABS layered surface. Appropriate manufacturer safety precautions must be followed during use.
