3DXMAX® Glass Fiber Reinforced Amphora™ AM1800 Co-polyester Filament
3DXMax™ GFR-PETG is a structural grade of Amphora™ 3D Polymer 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. We recommend our A2 Hardened steel Nozzles - HERE
Benefits of 3DXMax™ GFR-PETG include:
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.

Sturdy, and strong parts from this material! Very stiff, and the finish is great! Not as glossy as normal PETG, due to the glass fill. Sands well, but difficult to clean; It will DESTROY any exacto blades used to clean small blobs etc from parts! Like most PETG, it exhibits good dimensional stability versus ABS materials, and the glass fill seems to enhance this property. Tends to sag a bit on bridging, but with some tuning you can work it out. I don't seem to have stringing problems that many indicate are common while working with PETG. Flows very well above 240 or so. I have been using between 240 and 250, out of a .4mm nozzle with my prints, and so far the layer bonding is excellent, and the parts are very strong and rigid.

I use this for printing jewelry. Has a beautiful texture, clean and easy printing once tuned. It is strong enough that I can drill the connection hole in earrings into a 1mm x 3.5mm protrusion without the piece becoming weak.

This filament prints with the same settings as regular PETG with excellent results. The prints are clean, accurate, and with added stiffness over regular PETG. They have a rougher texture that can be sanded smooth.
The filament itself is not nearly as brittle as Carbon-Fiber infused filaments, so it bends well enough to easily fit through guide tubes, etc.

PETG is good material, but I do not like the surface so much, because it is too glossy and transparent. CF and GF can improve not only strength but also the surface problems.
At first time, I could not print this filament well with 230C extruder temprature. The PETG is very sticky material (this is good feature), so it sticks outside of nozzle, then makes large cake (2 mm large) in 30 to 60 minutes, and finally sticks to printed thing side.
Next I tried again with lower extruder temprature 210C. Then the cake had gone, but printed thing became very weak.
Next I tried again with higher extruder temprature 250C. Then also the cake had gone, and the printed thing got enough strength. With higher temprature, the printed thing gets much spider web filaments. But it can be removed easily, and I satisfied the surface quality.
I hope more colors, white, yellow, green, etc.
