Case Study: Haddington Dynamics achieves 58% cost savings and one-day assembly with Markforged

Haddington Dynamics - Customer Case Study

Haddington Dynamics, maker of the low-cost, open‑source 7‑axis Dexter robotic arm kit, faced the challenge of producing arms that were both cost‑effective and stiff enough to maintain 50‑micron precision. After a customer recommended moving away from weak PLA, the company turned to Markforged and its Onyx material with continuous carbon fiber reinforcement and purchased multiple Markforged printers to meet strength and accuracy requirements.

Using a fleet of Markforged printers to print carbon‑fiber‑reinforced Onyx parts, Haddington Dynamics consolidated assemblies and produced durable, swappable gripper fingers with tight tolerances and a professional finish. The change cut part count from 800 to under 70, slashed production lead time from weeks to single‑digit days (enabling assembly within a day in practice), reduced costs by about 58%, and lets the company recover a Markforged printer investment from the production of a single Dexter robot.
