3DXTECH OBSIDIAN™ PA6+CF 1.75mm/1KG

Obsidian PA6+CF is an excellent drop-in replacement for Markforged Onyx and is compatible for use in all Markforged printers. Obsidian offers excellent performance, appearance, and significant cost savings.

Obsidian PA6+Carbon Fiber

Obsidian PA6+CF filament was formulated to be a low-cost Markforged Onyx alternative suitable for all Markforged Printers. We developed this material after extensive analysis and testing on our in-house Markforged printer and many external beta testers. The result is a seamless printing experience that yields parts with excellent appearance and superb mechanical properties. Made using high-quality high-modulus carbon fiber and PA6 copolymer, Obsidian is an excellent Onyx alternative that allows our customers to save money when utilizing their Markforged Printer.

Don't have a Markforged printer? No problem - Obsidian™ is also compatible with all non-Markforged printers suitable for printing PA6+CF. Take advantage of this specialty material's excellent strength, stiffness, and appearance without overspending on Markforged Onyx™.

Benefits of Obsidian™ PA6+CF

• Drop-in for Onyx™ with no modifications required to print settings
• >30% cost savings over Markforged Onyx™
• Excellent strength and stiffness
• Resistant to aliphatic hydrocarbons (oil/gas/lubricants)
• Superior dimensional stability (low warp/shrink/CTE)
• Compatible with Markforged FX20, X7, X5, X3, Mark Two, Onyx Pro, and Onyx One printers

Obsidian™ was formulated to be a drop-in for Onyx™ with no modifications required to print settings.

Recommended Print Settings for Non-Markforged Printers:

• Extruder: 265-285°C
• Bed Temp: 90-110°C
• Nozzle: We currently recommend a hardened steel nozzle
• Bed Prep: Magigoo Bed Prep and 3DXTECH Polyimide Tape
• Heated chamber recommended
• Supports: AquaTek™ X1 USM Water Soluble Universal Support Material is designed to work with complex models
• Drying Instructions: 90°C for 4 hours if the filament shows signs of moisture

Carbon Fiber Reinforced Filament

What Is It? - 5-10 micron chopped carbon fibers. The fibers are aligned along the length of the material. This, along with their physical composition, is what gives this material its excellent properties.

What Does It Do? - Carbon fibers demonstrate many desirable material properties: high stiffness, high tensile strength, high heat tolerance, high chemical resistance, low weight, and low thermal expansion

How Does It Work? - Reinforcing plastic with carbon fibers produces a 3D printing filament that features the best properties of both carbon fibers and the chosen plastic.

What Is It Good For? - Ideal for any application that requires light weight and high stiffness. Carbon fiber reinforced parts, designed to use less material and save weight, are extremely popular in the aerospace, civil engineering, military, and motorsports industries.

Abrasive Material

This material is particularly abrasive amongst 3D printing filaments. Users may find that standard brass nozzles are chewed through very quickly compared to standard wear. Once worn, the nozzle diameter will increase inconsistently and the printer will experience extrusion issues.

Because of this, it is highly recommended to print this material through a hardened steel nozzle rather than with a softer metal. Hardened steel nozzles can often be inexpensive and easy to install, depending on the printer manufacturers instructions.
