Mark Two Fibre Extruder

Onyx Pro & Mark Two Fibre Extruder


The Markforged Mark Two and Onyx Pro have two extruders. One is dedicated to printing onyx (plastic extruder), while the other is dedicated to printing composites (fibre extruder). This fibre extruder is a unique component that enables it to 3D print parts with the strength of 6061 aluminium. It prints carbon fibre, fibreglass or Kevlar and reinforces parts during the print process with continuous strands of fibre.


When should I replace the Fibre extruder?

You may need to replace your fibre extruder if your Mark Two or Onyx Pro cannot extrude properly. Signs that your printer may be experiencing issues include a slowing down of the print process, an inconsistency when the composite is being extruded or skipping mid-print. The extruder mechanism itself is an incredibly robust part. However, it can become damaged if misused or mishandled. It can also become damaged in transit. If your fibre extruder has become damaged, then you will need to buy a replacement part.


The Fibre Extruder for sale here is a genuine Markforged part. It is a direct replacement for your printer’s existing fibre extruder. Replacing the extruder is a 10-minute job and once installed you will be ready to go. If you need any help choosing a part for your Markforged printer, call us on 01765 540 115 or contact us here

    MarkForged Spare Parts

    Markforged 3D printers are built to last. They have industrial-grade mechatronics and extruders, as well as hardy nozzles designed to cope with the abrasiveness of composites, which as they extrude, wear down regular nozzles.

    You may need to replace your extruder with a spare part (like-for-like replacement) if it develops a fault over time, or if you damage the unit accidentally. With good care, your extruder will last for thousands of print cycles but if you use it extensively this will reduce its lifespan, as with all mechanical components.

    Levelling shims are another Markforged spare part we sell quite regularly. These exist to eliminate flatness issues when calibrating the print bed. They aid alignment and levelling to ensure the bed clicks into place right and are compatible with all Desktop series 3D printers and may be suitable for others (please ask).

    Please only use genuine spare parts with your Markforged 3D printer and beware unofficial parts for they do not offer the same quality or performance. We are an authorised Markforged reseller, so all our spare parts are genuine.
