This PolyVinyl Alcohol (PVA) filament from our high-quality own brand RS PRO offers excellent adhesive properties, high tensile strength and flexibility. It is resistant to oil as well as grease and solvents.
Benefits
Perfect supporting material for dual extruder 3D printer
Dissolvable in water, making it a fantastic choice for a support material
A suitable primary material would be PLA
Unsuitable material would be ABS as that requires a bed temperature (90°C) that is above the glass temperature (62°C) of the PVA support filament
Cold water will get the job done, but for more speedy results, try warm water
Can use to create water-soluble moulds for ideal casting without the worry of ruining the cast when removing the mould
PVA is odourless, non-toxic, and biodegradable, which makes it safe for humans, animals and environment
Features
The recommended temperature for a heated bed is ± 35-60゚C
Melting temperature - 163 °C
Density - 0.75g/cm³
The damp filament can be dried at 50-55°C for 8-12 hours in a circulating air dryer
Applications
PVA is commonly used in the production of paper, adhesives, dissolvable packagings such as those seen in single-use detergent capsules, printing, eye drops, and textiles.
In 3D printing, it is often used as a support material for intricate printing.
Print Surface Materials
Some bed surfaces may need extra help in maintaining good adhesion. Use of washable surface treatment such as 3DLAC or PVA filament dissolved in a little water and applied to the bed before printing can improve the situation drastically.
Always degrease the print surface before each print.
Advice
Do not keep the filament idle in the nozzle at 180°C or over for more than 5 minutes as it will hydrolyse in the nozzle and therefore block the nozzle.
Must be kept in a sealed bag or container witch active desiccant when not in use
Dry PVA filament before each use
