The FX20 is the largest and most precise machine Markforged has ever produced. This large format 3D printer features an 84L heated build chamber and massive, verified-flat vacuum bed with print sheets. The motion control system offers closed loop control through precision linear encoders, and is tuned to move the 3kg print head rapidly and accurately. FX20’s turbo mode builds parts faster than any Markforged machine, while new XL spools offer four times the material without spool changeover. The FX20 is remarkably easy to use. It features a 7 inch touchscreen from which users can control every aspect of the printer. Automated calibration and leveling reduces operator input, while a wide variety of sensors give live feedback on machine performance. A material bay contains two active XL spools and can store two more with precise moisture control.

MATERIALS

Onyx™

Onyx

Micro carbon fiber filled nylon offers excellent heat resistance, surface finish, and chemical resistance

Applications

  • Functional Protos
  • Production Covers
  • Fit checks
  • Job Aids

Onyx FR is a flame-retardant variant of Onyx designed for use in applications where parts must be non-flammable. The material earned a UL Blue Card, and is considered V-0 (self extinguishing) at thicknesses greater than or equal to 3mm. It can be reinforced with any Continuous Fiber and is compatible with industrial composite 3D printers.

ONYX FR™

Fiberglass

Certified UL 94 V-0 rated flame-retardant micro carbon fiber filled nylon.

APPLICATIONS

  • Weld Fixturing
  • Aerospace Clips & Brackets
  • Laser Marking Fixtures
  • Energy/Electrical Brackets & Fixtures

Onyx ESD is a static-dissipative chopped carbon fiber nylon material, precision-engineered for a tight range of surface resistance. Onyx ESD meets ESD-safe requirements of the most stringent manufacturers, while offering the same industry-leading print quality of Onyx. Onyx ESD is stronger and stiffer than Onyx, with the same near perfect surface finish, making it suitable for advanced manufacturing applications from electronics assembly to industrial robotics and process automation.

ONYX ESD™

Smooth TPU

Stronger, stiffer, and ESD-resistant Onyx variant for industrial applications.

APPLICATIONS

  • Vacuum Grippers
  • Transfer Tools
  • Pick and Place
  • Transfer and Packaging Trays
  • Electronics Enclosures

Nylon White is an engineering thermoplastic that is non abrasive and can be stiffened with any of our continuous fiber options. It’s a versatile material both with and without reinforcing fibers.

NYLON

Onyx

Smooth engineering thermoplastic that can be easily painted or dyed.

Applications

  • Ergonomic Tools
  • Assembly Trays
  • Cosmetic Parts

Ultra high performance PEI thermoplastic compatible with continuous carbon fiber

ULTEM™ 9085 FILAMENT

ULTEM™ 9085 Filament

Ultra high performance PEI thermoplastic compatible with continuous carbon fiber.

APPLICATIONS

  • High Temperature Tooling
  • Aircraft Interior Paneling
  • Aircraft Brackets, Handles, and Knobs
  • Custom Ducting
  • Composite Molds and Layup Tools

Carbon Fiber

Carbon Fiber

Stiff, strong, and extremely light, carbon fiber reinforcement yields parts capable of replacing machined aluminum.

APPLICATIONS

  • Custom production
  • Bridge production
  • High performance end-use parts
  • High-strength tooling

Carbon Fiber FR is a flame-retardant variant of Markforged’s unique, ultra-high-strength Continuous Carbon Fiber — when used to reinforce a Composite Base material like Onyx FR, it can yield parts as strong as 6061-T6 Aluminum. It’s extremely stiff and strong, and can be precisely laid down in a wide variety of geometries. Programmatically trace curved features, reinforce holes, and mimic unidirectional fiber layups — all within a few clicks.
