Description
Makergear M2 Hercules A2 Hardened Steel Nozzle
M2 Hercules A2 Hardened Steel Nozzle are wear resistant, high lubricity nozzles compatible with the very popular Makergear M2 printer.  Compatible with the M2 and M3 printer versions.
Hercules nozzles are manufactured in the USA using heat treated A2 tool steel and coated with Duraplat3-d wear-resistant coating for enhanced wear and flow.  Compared to stainless steel nozzles, Hercules nozzles are 3X harder, have 50% better heat transfer, and 5x the wear life.  The M2 Hercules A2 Hardened Steel Nozzle is the clear cut choice for printing with more abrasive filaments like ourCarbonX Carbon Fiber PLA. Compatibility
- Makergear M2
- Makergear M3
- V3, V4 hotends

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.

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.
