MX3D Robots 3D print stainless steel bicycle, designed by students of TU Delft.
At the MX3D facility in Amsterdam a student team from TU Delft has developed a fully functional 3D printed stainless steel bicycle. The students designed the frame of the bicycle to demonstrate the potential of the MX3D method for 3D printing metal.
The students achieved the goal of their three-month project by printing the bicycle frame in collaboration with our MX3D engineers in Amsterdam. The bicycle was designed as part of a research project at the AMS Building Fieldlab into the viability of WAAM, Wire Arc Additive Manufacturing, a 3D printing technique based on MIG welding. The AMS Building Fieldlab is a collaboration between MX3D, TU Delft and AMS / Amsterdam Institute for Advanced Metropolitan Solutions. The collaboration focuses on the wider impact of WAAM in the city environment.
“3D printing has exploded in popularity in the last decade but for those wanting to print medium to large scale objects, there are still significant limitations in the technology. This method of 3D printing makes it possible to produce medium to large scale metal objects with almost total form freedom.” – Harry Anderson (Arc Bicycle team)
In a video about the production of the bicycle, the students prove the frame’s strength by riding it around the city of Delft. Demonstrating that it can really be used in real world conditions. It performs well on the often bumpy cobblestone streets of the city.
“It was important for us to design a functional object that people use everyday. Being students in the Netherlands, a bicycle naturally came to mind. A bicycle frame is a good test for the technology because of the complex forces involved.” – Stef de Groot (Arc Bicycle team)
The project was realized in collaboration with MX3D, an R&D start up in Amsterdam, who specializes in Robotic Additive Manufacturing. The company has developed a ground breaking method for using multi axis robotic arms as 3D printers. This allows metals and resins to be printed mid-air in any direction without the need for support structures. The company made world news last year when it released plans to 3D print a steel pedestrian bridge in Amsterdam. Through the 3D Building FieldLab, MX3D invited the students to studie and experiment with the many aspects of this innovative digital fabrication technology.
“For MX3D its great to facilitate this field lab as it creates a hands-on stimulating learning environment that benefits both our company and scientific research.” – Gijs van der Velden (COO, MX3D)
A short Q and A with the team, if you have more questions please contact press@MX3D.com
Q: Can you tell us a little more about the printing process?
A: The printing process used to produce the frame is known as Wire and Arc Additive Manufacturing (WAAM). The method allows for multi axis 3d printing, using articulated robot arms because of the self supporting nature of the material. It also allows you to print larger objects than other types of 3D metal printing.
Q: Is the bicycle heavy?
A: This prototype weighs about the same as a normal steel bicycle. It can be optimized a lot more. However our main concern when designing the frame was the strength. We didn’t know how the material would behave, so we chose to make it extra strong and sacrifice a bit of lightness.
Q: How does it ride?
A: We tested the bicycle on the streets of delft and it performed well. It offers quite a smooth ride. The wheel base and the low centre of gravity of the bicycle make it easy to take fast turns. It has a fixed gear configuration which was the most elegant solution for us as its primarily a concept bicycle.
