3DXTECH CARBONX™ PETG+CF 1.75mm/750g

CarbonX PETG+CF Carbon Fiber Reinforced Co-Polyester

CarbonX PETG+CF is made in the USA using high quality PETG and high modulus carbon fiber (not carbon powder or milled carbon fiber). CarbonX PETG+CF is a CF reinforced 3D printing filament that is better than the competition. This filament is ideal for anyone looking for a structural part with high modulus, excellent surface quality, dimensional stability, light weight, and ease of printing.

The benefits of CarbonX™ PETG+CF include:

• Superior chemical resistance compared to ABS
• Amorphous structure that gives low, nearly isotropic shrinkage
• Low moisture absorption, 3 times lower than ABS
• Very low odor during printing
• Wide working range from 230-270°C

Chemical resistance of PETG:

Unstressed tensile bars molded from 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 ketones and aromatic hydrocarbons dissolve or swell the plastic.

Recommended print settings:

• Extruder: 230-260°C
• Bed temperature: 70-90°C
• Nozzle: We currently recommend a hardened steel nozzle with a minimum diameter of 0.4mm.
• Other: The ideal layer height is 60% of the nozzle diameter. We do not recommend printing layers smaller than 0.2mm with carbon fiber reinforced filaments.
• Bed Preparation: Magigoo Bed Preparation Sticker
• Heated room: not required
• Supports: Water-soluble AquaTek X1 USM works great for complex parts.
• Drying instructions: 65°C for 4 hours.

Carbon fiber reinforced filament

What is it? - Carbon fibers 5-10 microns wide. The fibers are aligned along the axis 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 the carbon fibers and the chosen plastic.

What is it good for? - Ideal for any application that requires light weight and rigidity. 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 among 3D printing filaments. Users may find that standard brass nozzles chew up very quickly over standard wear. Once worn, the nozzle diameter will expand inconsistently and the printer will have extrusion issues.

For this reason, it is highly recommended that you print this material through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easy to install, depending on your printer manufacturer's instructions.
