Carbon‑Fiber Hacksaw: A Lightweight Tool Printed on the Markforged Mark Two

Let’s cut to the chase: the Markforged Mark Two can print carbon‑fiber parts that rival industrial‑grade tools. Here’s a lightweight carbon‑fiber hacksaw that exemplifies the printer’s capabilities.

At Markforged we encourage our engineers to print a new part each week, deepening our understanding of customer needs.

Every Friday, our 'Part of the Week' showcase highlights the best designs.

Last Friday, I presented a fully functional carbon‑fiber hacksaw that I designed and printed on the Mark Two.

My goal was to create a cutting tool that is strong, functional, and lightweight, suitable for diverse applications.

The blade is reinforced with a zebra‑pattern carbon‑fiber lattice, delivering optimal rigidity while keeping weight low.

Unlike Kevlar, which offers some flex, carbon‑fiber provides the strength required for a hacksaw, making it the ideal material.

In Eiger, the automatic reinforcement feature satisfies 80% of our customers, but some require finer control over fiber placement and how the Mark Two lays down continuous strands.

For this hacksaw, continuous fiber strands were laid in a concentric pattern; future iterations will include isotropic layers to reduce torsion during use.
