Review – Application – 3D-Printer Ragnar Prototyping

Post navigation

We could not have found a better time to visit Ragnar Prototyping. The company, which specialises in 3D printing, put a prototype into operation for the first time at Aarhus University, Denmark, with an impressing print area of 1000 x 1500 x 1000 mm. And this printer is full of igus® parts.

The new dimension of 3D printing: 1000 x 1500 x 1000 mm. Merely the red ribbon indicates the celebratory atmosphere of the moment
Ragnar employees and students from the university all had their hands full in the few hours running up to this historic moment for the company and most of them got barely any sleep the previous night. One of these is Sylvester Stormby-Szöllösi, cofounder and Chief Technical Officer (CTO) of Ragnar Prototyping. “Normal printers are smaller and thus suited to small prototypes”, he explains. “The models created by this printer can be the same height as a human.” But it is not all about spatial dimensions. “Much of what is currently printed is simply for show”, comments Stormby-Szöllösi. However, for the creator of Ragnar Prototyping it is not just about models, but about the future ability to create usable products such as sofas and chairs.

In this regard, the Danes are breaking new ground, and it becomes clear to me when speaking to Sylvester Stormby-Szöllösi that the name Ragnar was chosen for good reason. Ragnar Lodbrok was an important Viking who took risks, entered uncharted territory and “enjoyed cool adventures, just like us”, comments Stormby-Szöllösi with a wink. The Danish designers are following in the footsteps of their legendary forefather.

Many igus® components are found here: drylin® W profile guides, dryspin® high helix threads, e-chains® and iglidur® plain bearings

A look into the printer makes it possible to see various igus® components: echains ®, drylin® linear guides and dryspin® high helix threads, or to be more precise, the zero-backlash lead screws for sustainable minimum reverse play, as well as iglidur® plain bearings. Stormby-Szöllösi highlights the high pitch of the lead screws, which makes it possible to quickly position the print head for large objects. But why igus®? Mainly because of the self-lubricating properties. Stormby-Szöllösi: “We see igus® as a pioneer in its field and feel honoured to be the first company to use its technology for 3D printing” – we are simply leaning back for a moment and enjoying the complement.
