In about a year of work, local historian Leo Kölbl created a meticulously precise model of the Ottenhofener Hofmarkt - using 3D printing.

Now comes the garden.

Ottenhofen

– In their successful exhibition about the school, the Ottenhofen local researchers have shown a small sensation in the background: the Hofmark of Ottenhofen in its heyday in a meticulously accurate model.

But it's not just any model, it's a 3D print.

This state-of-the-art technology is becoming more and more affordable, even if the device with which this model was manufactured must belong to the absolute professional class.

By the way: everything from the region is now also available in our regular Erding newsletter.

Leo Kölbl from the local researchers is responsible for this work.

He reports to the local newspaper: "I've been busy for a year." The basis was the existing plans and photos, he reports.

for the implementation as a model, the terrain also had to be recorded.

The local researchers can fall back on a friend who is a geometer and who has supported them.

The entire site was also completely surveyed in terms of altitude.

Then all these details had to be brought to the right scale.

Kölbl reports that what is still in existence today was the model for this work.

"We actually had to convert everything," he says.

This applied to every single window and all other details of what was once a representative square complex.

Kölbl admits: "It was amazing work!"

All of this had to be transferred to a computer program, which in turn could control the large 3D printer.

In order to make the Hanze reasonably manageable, the huge data set had to be divided into six parts.

The individual roof parts were manufactured individually.

The result is precisely this exact model, which was shown for the first time at the exhibition in the school sports hall.

When asked, Kölbl was able to explain why there wasn't much more "fuss" about this enormous work: It's not really finished yet, because the large garden also belonged to the Hofmark.

In it stands the tea pavilion, which has been preserved to this day, but is not open to the public.

Kölbl has taken on this garden as his next work.

However, as he said, this will not be 3D printing, but classic model construction.

Visitors to their exhibitions can always marvel at the fact that the local researchers can do this too: the model of the Ottenhofen train station has been around for quite a while.

In spite of all this, Kölbl is well aware of his pioneering work, since the technology of 3D printing makes it possible to reproduce finds exactly in archeology and thus to show them to a broad public safely and without the considerable costs for insurance and specially equipped showcases.

He expressly reminds that there are also 3D scanners that scan such a found object with an accuracy of a fraction of a millimeter and then prepare it for the printer via software.

Hofmark and garden are to be created on the same scale and would then form a presentable unit, according to the local researchers' plan.
