Brand

Bondtech

The company was established in 2014 by Martin Bondéus, who had previously used the 3D printing technology in his work as a product developer. When certain patents regarding the FDM technology expired at the beginning of the 2010s, Martin set out to build a 3D printer based on a pre-designed kit. The result, however, wasn’t satisfying. The performance and quality just weren’t there. Stubbornly, Martin therefore started building his very own printer from the ground up, not using kit products. This time the result was much better, but unfortunately still not good enough. Grinding, slipping and under extrusion translated into several failed prints. Scouring the internet for advice, he realized that the problem with bad, unreliable extrusion was universal. Everyone seemed to suffer from the same dilemma. An idea was born. Today, Bondtech manufactures Bondtech Dual Drive extruders and other innovative 3D printing products to users and retailers across the world. Constantly improving our offer, we believe this is just the beginning.
