Black Glass Fiber Reinforced PETG

3DXMAX® Glass Fiber Reinforced PETG


3DXMAX® Glass Fiber Reinforced PETG

3DXMax™ GFR-PETG is a structural grade of PETG Copolyester that expands your capabilities for adding strength and toughness to your printed part.  We chose a specialty grade of glass fiber reinforcement that was ideal for co-polyester and 3D Printing.  Our carbon fiber grades offer great structural reinforcements - but they are only available in black.  GFR is ideal for applications where you want brilliant color and structural toughness.  Three colors now - more coming soon!

This filament is suitable for use in practically any desktop 3D Printer that has a heated bed.  Please note - glass fiber reinforced filaments are abrasive and can wear out a brass or aluminum nozzle.

Benefits of 3DXMax™ GFR-PETG include:

  • Brilliant Colors + Structural Reinforcement
  • Specialty glass fiber chosen to be compatible with PETG
  • Superior Chemical Resistance vs. ABS
  • Amorphous:  Low and near isotropic shrinkage
  • Low moisture absorption:  3X lower vs. ABS
  • Very low odor emitted during printing
  • Wide processing range:  230 - 270°C 

Chemical Resistance:  Unstressed tensile bars molded of PETG exhibit good resistance to dilute aqueous solutions of mineral acids, bases, salts, and soaps, and to aliphatic hydrocarbons, alcohols, and a variety of oils. Halogenated hydrocarbons, short chain length ketones, and aromatic hydrocarbons dissolve or swell the plastic. 

Recommended Print Conditions:

  • Extruder:  Ideally 230 to 260°C
  • Platform Temp:  60 to 90°C
  • Platform Prep:  Clean glass w/ Kapton Tape, PVA glue or hairspray
  • Nozzle:  We currently recommend minimum 0.40mm orifice or larger.
  • Glass fiber filament is more abrasive than unfilled materials, so extended use will result in more wear on your nozzle. We recommend our A2 Hardened steel Nozzles - HERE
