SANSIL 3D
Material
PVA — Polyvinyl alcohol, water-soluble support
Not a material for the part itself: it is what makes impossible shapes possible.
Use it for
- Internal channels, closed cavities and undercuts
- Threads and gears printed with no rework or sanding
- Printed assemblies that come out already assembled, in one piece
What it will not do
- Three times the price of PETG: only worth it if the load demands it
- Matt, slightly rough surface — not a cosmetic material
- Black only

What we have learned using it
A lot of enquiries come in asking for PVA when PETG is more than enough. We say so: an over-specified part has never won anyone's loyalty.

Names are the manufacturer's own and serve as the ordering reference. The colour runs through the material, it is not painted on — swatches are indicative, a physical sample prevails.

Values measured by the filament manufacturer on standardised specimens. A printed part will differ with orientation, infill and settings: we validate on a test part on request.
Technical data sheet (TDS) from the filament manufacturer, Bambu Lab, in English, as published on its store on 6 September 2026: mechanical and thermal properties measured on specimens, drying and printing conditions. It is the document to attach to a technical file; we also send it with the order on request.
