15 m Sample | 1.75 mm | Vinyl 303 "Natural"

$4.00 USD

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.


  • 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

        *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.
