Description
Obsidian-GF
Glass Fiber Reinforced PA6 filament was formulated to offer rich colorful
options in an engineering-grade material for your Markforged printer.
Obsidian-GF is a lower-cost drop-in Markforged Onyx Alternative suitable for
all Markforged printers. We developed this material after extensive analysis
and testing on our own in-house Markforged printer and many outside beta
testers. The result is a seamless printing experience that produces parts
with an outstanding appearance and excellent mechanical properties. Made
using premium chopped glass fiber and PA6 copolymer, Obsidian-GF is an
excellent alternative to Onyx™ that allows our customers choose brilliant
colors, excellent mechanical properties, and save money when using your
Markforged printer. Don’t have a Markforged printer? That’s no problem – Obsidian™-GF is also compatible with all non-Markforged printers that are suitable for printing PA6+GF. Take advantage of the excellent strength, stiffness, and appearance of this specialty material without over spending on Markforged Onyx™. |

Abrasive Material
This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues.
Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
Material DETAILS
Glass Fiber Reinforced Filament
What Is It?
DescriptionFibers made of glass reinforced into the polymer during manufacturing and aligned along the axis of filament.
This, along with their physical makeup, give this material enormous strength and mechanical properties.
What Does It Do?
Glass fiber reinforcement gives material a lot of desirable properties:
High strength
High stiffness
High chemical resistance
Low thermal expansion
How Does It Work?
Reinforcing plastic with glass fibers produces a 3D printing filament which exhibits the best properties of both fiberglass and the plastic of choice.
What Is It Good For?
Ideal for any applications which require strength and rigidity.
For these reasons, glass fiber reinforced filament is very popular in automotive, mechanical, civil engineering, and research industries.
