Description
DREMC's PBT-GF is a polybutylene terephthalate with glass fiber 3D printing filament. Its <10% glass fibre composition provides exceptional heat resistance and minimal shrinkage. With impressive rigidity, tensile strength, and excellent anti static properties. This filament is a reliable choice for printing durable and stable parts. Ideal for a variety of applications that demand high-quality printed components such as connectors/switches in automotive applications.
Please note, this has been EOL for retails customers, these are still avaible to be purchased through B2B (MOQ 1 carton), this has been replaced with PC PBT GF which is easier to print.
Materials Features/Applications
- High quality BASF Ultradur PBT-GF resin (contain chopped GF<10%)
- Note 1: This material is highly recommended for tool changer/IDEX printers. For better bed adhesion and to reduce warping, it is best to use PC ABS, ABS, or PC(similar material blend) for the first couples layer or support raft. A suitable bed adhesion solution or compatible build plate is required, as this material does not adhere well to most standard bed adhesives and build plates. (More Info: https://support.dremc.com.au/en/support/solutions/articles/51000463967-dremc-pbt-gf-first-layer-printing-guide) Otherwise PC PBT GF is easier to print in comparison and adhere to most textured PEI without issues.
- Note 2: at least 60-90c minimal active/passive chamber is recommended, our recommendation is 80-100c+, to reduce warping/material shrinkage during printing on complex parts.
Materials/Spool/Packaging Information:
- Plastic spool and packaging
- Vacuum sealed bag with an additional re-usable mylar bag
- Diameter: 1.75mm (+/- 0.05mm)
- Net weight: 1KG
- Density: 1.35 g/cm3
- Empty Plastic Spool: ~150g
Abrasive resistance nozzle is requirement due to glass fibre, plated/brass nozzle can wear quickly and cause inconsistent prints and will destroy those types of nozzles.
Printing Settings/Requirements
A wear resistant nozzle must be used, carbon fiber material is abrasive and will wear standard brass nozzles and >0.5mm nozzle is recommended.
For best results, dry filament using a filament drier before use and print from dryer running or dry box. Keep in an airtight container or included mylar bag for medium/long term storage with silica desiccant. [If you hear popping or inconsistent extrusion while purging filament, suggest drying before printing for best results] Filament Drying Guide

Materials tested compatibility on Vision Miner 22 Idex V3, Flashforge Guider 3 Ultra and Modified Voron Trident Idex / Single Toolhead Voron Trident / Bambu X1E with first layer using PC ABS or ABS.
Note: At temperatures above >290°C can and may emitted: carbon monoxide, tetrahydrofuran. Material is stable up to 280°C and do not give rise to hazards due to molecular degradation or the evolution of gases and vapors. Like all thermoplastic polymers. See Product SDS.
Note: Ensure your hotend is accurately temperature-calibrated, and do not exceed the recommended printing temperature of 280°C. Always print in an enclosed setup with active exhaust, and make sure your workspace is equipped with a carbon monoxide sensor for added safety.

| Nozzle Temperature | 260°C - 280°C |
|---|---|
| Build Plate Temperature | 100°C - 120°C |
| Build Surface Material | Works well with most common build surfaces. We recommended PEI Build Plate (Smooth/Textured) with Bed Adhesive such as Glue Stick / Magigoo HT. [Do not print on bare PEI without bed adhesive barrier] |
| Cooling Fan | LOW-MEDIUM for better surface quality OFF-LOW (<10%) for better strength |
| Enclosure / Heater Chambers |
Recommended for complex larger geometries. Recommend VOC/Air Filtering/fume extraction or print in well ventilated room with fume extraction. |
| Printing Speed | 40 mm/s - 100 mm/s (<60mm/s is our recommendation for most pro-consumer hardware) |
| Retraction | The ideal retraction settings vary from printer to printer. If you find the retraction settings are causing gaps in your part, the following settings may help. Direct Drive: Retraction distance of 0.5 - 1mm with retraction speed of 20mm/s Bowden: Retraction distance of 2 - 3mm with retraction speed of 20 - 40mm/s |
| Drying Recommendation | ~80°c for 8-12hr (Only dry if filament is wet, over drying/repeat drying can damage filament) REQUIRE PRINTED CLAMP WHEN DRYING (Filament Dryer Guide) |
| Storage | Keeping filament in an airtight container or provided Mylar bag with new/dried desiccant. |
Note: Due to the low co-efficient of friction please ensure you have smooth filament path from filament box/dryer. We recommended 3x4mm PTFE to be used for reverse bowden.
Based on 0.5/0.6 mm nozzle. Printing conditions may vary with different printers and nozzle diameters.
Test Print: Voron SB Main Body - Note: (First layer is PC ABS with Brim on Textured PEI with Magigoo)
* As always you should do temperature to tower as each machine printing temperature may vary depending on hotend/printing speed etc.
