MAX-G GF-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.
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.
We recommend our A2 Hardened steel Nozzles
Benefits of MAX-G™ GF-PETG include:
- 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 245 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 due to the glass fiber content of the PETG
- Glass fiber reinforced 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
