Vinyl 303 is a high-tech filament made of polyvinyl chloride (PVC), widely used (commodity) plastic.

Thanks to its great properties, this is a perfect choice for functional prototyping, spare parts, or printing of objects for everyday use.

Features:

Flame retardancy is given by its chemical structure (naturally without additives)
Excellent chemical resistance to oils, salts, solutions, and water
Functionality, toughness, rigidity
Great hardness and mechanical properties
High impact resistance
Low warping
Low moisture absorption
High density
Safe for use in electrical and electronic equipment
Recyclable

Working temperature:	215–230 °C
Heated bed:	80 °C
Diameter:	1.75 mm
Diameter tolerance:	+/- 0.05 mm
The length of the filament:	15 m
Available Spool variants:	Vinyl 303 "Black" Vinyl 303 "Natural"

Warning! Toxic fumes might be emitted during printing. Follow the Safety recommendations!
3D Printing Guide
For a good adhesion use PVA glue or 3DLac
Keep in non-translucent resealable sachet, bag, or box to minimize the effect of UV light
Drying filaments before processing

*Always test little 3D printed object under the specific conditions of usage (chemical, temperature, time). It always depends on the conditions of processing, design, and specific type of chemicals.

The input material was carefully selected to achieve the best processability and final properties. Fillamentum’s products are always produced from the precisely specified type of material, with the highest stability across all the batches. The customers can rely on the best quality at any time they use our filament.
