Vinyl

Vinyl filament is made from PVC (polyvinyl chloride), one of the most widely used plastics in industry. Fillamentum Vinyl 303 combines toughness, hardness and natural flame retardancy with low warping, which makes it a good fit for functional prototypes, spare parts and everyday objects. Because PVC can release toxic fumes during printing, it is reserved for experienced users with good ventilation. It ships from our warehouse in Senec, Slovakia.

Properties of Vinyl 303

• Flame retardant by nature – given by the chemical structure, without additives. Fillamentum states it meets the V0 benchmark, but there is no UL94 certificate.
• Chemical resistance to oils, salts, solutions and water.
• Hard and tough – Shore hardness 78D, high impact resistance and rigidity.
• Easy to handle – low warping and low moisture absorption.
• High density of 1.35 g/cm³; Vicat softening temperature 71 °C.

Print settings

• Nozzle about 220 °C, bed about 80 °C.
• Part cooling 0–50 %.
• Print speed 40–60 mm/s.
• Enclosure recommended, together with good ventilation or fume extraction.
• Use a brass nozzle, not steel – steel may corrode.
• Drying: 70 °C for 2 hours.

Typical uses

Functional prototypes, spare parts, everyday objects and parts that come into contact with oils, salt solutions or water.

Pros and cons

• Pros: tough and hard, flame retardant without additives, chemically resistant, low warping.
• Cons: toxic fumes may be released while printing, steel nozzles may corrode, recommended for advanced users only.

Frequently asked questions

Why should I print Vinyl 303 with a brass nozzle?

Fillamentum warns that steel nozzles may corrode when printing PVC, so a standard brass nozzle is the right choice.

Is it safe to print PVC at home?

Only with good ventilation, ideally an enclosure with fume extraction, and following the safety recommendations in the manufacturer's printing guide.
