Martin Bondéus is the man behind the renowned dual drive extruder that has become somewhat of a industry standard when it comes to high performance and reliability. If you are suffering from quality issues related to extrusion or if you just take your 3D printer to the next level, a Bondtech extruder is the way to go!
I have only met Martin once but we have exchanged emails over the years and i have done some beta testing aswell. For 2017 Bondtech is a new sponsor, adding the performance and quality of their awesome extruders to my BCN3D Sigma.
