Markforged Onyx (Nylon Carbon Fiber)

Markforged’s Continuous Fiber Technology is a groundbreaking innovation in the field of additive manufacturing, setting it apart from traditional methods like regular Fused Deposition Modeling (FDM). This technology involves the embedding of continuous strands of reinforcing fibers — such as carbon fiber, fiberglass, or Kevlar — within a thermoplastic matrix material during the 3D printing process.

The process starts similarly to standard FDM, where a thermoplastic filament is extruded layer by layer to form the base shape of the part. However, the key differentiator is the incorporation of continuous fiber strands within these layers. The printer’s specialized nozzle lays down continuous fiber in specific areas of the part, as dictated by the design, to provide enhanced structural strength. This technique allows the printed parts to achieve a strength-to-weight ratio comparable to metal, making it particularly advantageous for industrial applications that require robust, yet lightweight components.

The ability to reinforce parts selectively means that material can be added only where it’s most needed, optimizing the strength while minimizing weight and material usage. Markforged’s Continuous Fiber Technology is widely used in the aerospace, automotive, and manufacturing industries for producing high-strength, functional parts and tools. This method offers a unique blend of flexibility in design, alongside the practical advantage of creating parts that are exceptionally strong and durable, yet significantly lighter than their all-metal counterparts.
