Industrial Composite 3D Printer


Starting at: 

Push the boundaries of 3D printing with access to the full range of Markforged Nylon and Onyx base materials and reinforce with your choice of carbon fiber, fiberglass, or Kevlar for parts with unparalleled strength and durability. 

What features do you get with X7? 

  • Precision-machined hardware, advanced sensors, and unique software drive leading edge accuracy and reliability. Markforged industrial carbon fiber 3D printers offer micron-level laser scanning for closed-loop calibration, reliably yielding parts with high repeatability and near-perfect surface finish. 
  • Design your part, upload it into Eiger browser-based software, select from a wide range of Composite Base filaments and Continuous Fibers, and hit print. It’s that simple. 
  • Advanced hardware, electronics, and software are designed to give you a seamless user experience. 
  • A reinforced, precision-machined gantry and a precision ground print bed can both be removed and replaced with 10 μm repeatability. 
  • Each piece of hardware in the filament extrusion system, from the nozzles to the extruder hobs, is optimized to resist wear from micro carbon fiber filled nylon filaments and maintain print quality over thousands of hours. These parts are also designed to be easily accessed and replaced when needed. 
  • Out-of-material sensors ensure that you’re always up and running and will pause your print when your material spool ends so you don’t lose print progress.  
  • A scanning laser on the printhead enables the printer to dynamically adjust the first layers of a print to achieve perfect bed adhesion. 
  • The X7 has a 3rd-generation fiber reinforcement system that is uniquely capable of printing four unique types of continuous fiber reinforced parts. 

Blacksmith software

Blacksmith for X7 establishes and streamlines the quality control process for additively manufactured parts. Get to market faster with confidence in your parts. By scanning parts, while they print, the X7 is the only industrial-grade FFF 3D printer with in-process part verification. Blacksmith is a subscription feature available through Eiger, the additive manufacturing software for Markforged. lt scans, measures, and compares dimensional accuracy data of printed parts to their design files giving manufacturers reliable parts right off the print bed.

Looking for something a bit more rugged? 

What features do you get with X7+? 

  • For printed parts that are strong, durable, impact-resistant, and flame-retardant, you can print with Markforged’s full range of Composite Base materials and Continuous Fibers. 
  • Pelican AL3232 single lid case with custom foam modules and moving component locks to mitigate damage during transport. The X7 FE solution has been included in MIL-STD-810 testing in support of a DoD Program of Record. 
  • Increase supply chain resilience by printing tools, adapters, and replacement parts for equipment at the point of need. Ensure dimensional accuracy for the most critical tolerances with the integrated laser micrometre and adaptive bed levelling. 
  • Simple user interface for effortless print configuration, with onboard utilities for guided printer calibration and maintenance. The X7 FE can be fully set up and ready to print in minutes. The unit contains the materials, spare parts, and tools needed to sustain production between resupply opportunities. 
  • Lightweight unibody construction, precision-machined gantry, and laser-assisted calibration ensure consistent performance, wherever you go. 
  • Digitize mission-critical component inventories to bypass costly high-risk supply chains. Bring innovation directly to the point of need with powerful Offline Eiger software, which rolls improvements from Cloud Eiger into updates when you re-surface for Wi-Fi. 



  • The go-to Markforged composite for printing accurate parts with a smooth surface finish, Onyx is a Nylon base reinforced with chopped carbon fiber that boasts high chemical and heat resistance. Onyx prints enjoy both a high-end finish and twice the strength of parts from other composite printers. Try printing with embedded carbon fiber reinforcements for aluminum strength parts.

Onyx FR (FR-A)


  • Onyx FR and FR-A offer the strength and reliability of the Markforged flagship Onyx composite material designed specifically for the aerospace and transportation industries. Get strong, light weight, and fire-resistant prints that can even be reinforced with any Continuous Fiber inlay for added durability. The material earned a UL Blue Card and is considered self-extinguishing (V-0) at 3mm or thicker.


*Onyx FR-A and Carbon Fiber FR-A are purpose-built for the requirements of the aerospace, transportation, and automotive industries. Onyx FR-A and Carbon Fiber FR-A as printed on the Markforged X7 are undergoing qualification through the NCAMP process.


Onyx ESD


  • Onyx-level durability that’s stronger, stiffer, and ESD resistant for a wide range of industrial applications. Developed specifically to have an extremely tight range of surface resistances that meet the ESD-safety requirements of even the strictest manufacturers, Onyx ESD is a static dissipative safe variant of Onyx that offers strength, stiffness, and a near-perfect surface finish.

Nylon (White)


  • Affordable, easily painted, non-abrasive, and durable, Nylon and Nylon White are the materials-of-choice for quick cosmetic prints that are likely to be handled over and over again. Nylon is an unfilled, smooth engineering thermoplastic that is great for ergonomic surfaces and workholding structure.

Carbon Fiber

  • The literal and symbolic backbone of aluminum-strength, composite 3D printed parts, Carbon Fiber is the classic Markforged high-strength Continuous Fiber. Take advantage of the highest strength-to-weight ratio of the Markforged reinforcing fibers, 6x stronger and 18x stiffer than Onyx! Carbon Fiber reinforcement is commonly used to replace traditionally machined aluminum parts and fixtures.



  • As an entry-level continuous fiber material, Fiberglass is perfect for printing parts 10x stronger than ABS, or 2.5x stronger and 8x stiffer than Onyx alone. Print robust tools, jigs, and fixtures with Fiberglass inlays on the Onyx Pro and X5, and on the Mark Two and X7 for a more affordable, accessible carbon fiber alternative.

Fiberglass (HSHT)

  • Of course, High Strength High Temperature Fiberglass (HSHT) is iconic for its aluminum strength and high heat tolerance. Onyx parts reinforced with HSHT are strong at both low and high temperatures and are 5x as strong and 7x as stiff as parts printed in pure Onyx. It’s best used for durable parts designed to operate in high temperatures.

Kevlar (Aramid Fiber)

  • Tough Continuous Fiber for high-impact applications, Aramid Fiber is a Kevlar-based specialized continuous fiber known for its extreme energy absorption. Armor up with Kevlar reinforcement inlays that add strength and durability for parts as stiff as fiberglass and much more ductile. When laid into Onyx or another composite base material, achieve impact-resistant pieces that are nearly immune to catastrophic failure!

Precise PLA


  • Precise PLA is the easy-to-print plastic for precision concept modeling and validation. Based on the most common 3D printing prototyping material, Precise PLA 3D prints without warping and comes in a variety of colors. Best of all, it’s affordable. So you can use as much as you need to fine-tune your designs before implementation.

Smooth TPU 95A

  • Smooth TPU 95A is a rubber-like material that when used with Markforged composite printers offers product developers and manufacturers the ability to create flexible, impact-absorbent parts on demand.

Carbon Fiber FR


  • 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
