Size matters: Flurin Camenzind, an engineer from Zurich Oberland, has developed a 3D printer for large-scale projects.
What is the technical challenge of macro-printing, Mr. Camenzind?
In principle, it’s possible to use an ordinary 3D printer to produce large objects. The problem is the price of the raw materials: The filaments currently used in fused deposit modeling (FDM) are expensive and make it uneconomical to use an additive procedure to produce everyday articles of use such as a chair.
Do you print with cheaper materials?
I work with plastic granules such as the ones used in industrial injection molding. However, I had to construct a new print head – a kind of micro-extruder.
Your company, 3DDD, handles print jobs. How did your customers react to your innovation?
I have already completed some print jobs for them and will continue to do so on request. In the long term, however, I see myself not as a printing service provider, but as a mechanical engineer.
Will everyone print their furniture at home in the future?
That would be a possible scenario. However, for private individuals my large-scale printers would still be a bit expensive.
Why? How much are they?
About the same as a small or mid-range car.
