Primalloy – Flexible 3D filament | Interstate Plastics

1.75MM 500G REEL WHITE 3D Printing Flexible Filament Welding Rod, Primalloy

Verbatim’s PRIMALLOY Flexible 3D filament, provided by Interstate Plastics, is a high performance, a polyester-based thermoplastic elastomer which consists of a mixture of a crystalline aromatic polyester block (mainly PBT) and an uncrystalline polyether block (mainly poly-tetramethylene-ether-glycol). This mixture gives objects printed with PRIMALLOY unique flexibility without sacrificing durability.

Objects printed with PRIMALLOY filament feature good mechanical strength, oil resistance, chemical resistance, and flex-fatigue resistance. PRIMALLOY also offers excellent heat resistance as well as hardness stability within a wide temperature range.-

With a diameter tolerance of 0.05mm, Verbatim PRIMALLOY 3D filaments ensure consistent feeding and stable prints, every time. All Verbatim 3D filaments feature a custom spool designed for strength and balance for uniform feeding. filaments are packaged in a vacuum-sealed bag, including desiccant, to promote longevity and prevent the introduction of moisture. Verbatim PRIMALLOY Flexible 3D Printing filaments are backed by a 1-year limited warranty.


  • For best performance, use Polymide Tape with a heated build platform (40- – 50- C / 104- – 122- F)
  • To prevent layer drooping, apply forced air cooling on an object as it builds.
  • To prevent feed jams, utilize slow print speeds (< 30 mm/s) and turn off retraction. Avoid excessive pressure in the pinch feeder.
  • Not recommended for printers with significant distance between the pinch feeder and hot end (eg. >15mm).
