Mitekgruppen, a Swedish scale-model company, created an almost exact replica of the city of Stockholm using Stratasys Dimension Series FDM 3D printers. Even though scaled down replicas of practically every major landmark — from the Golden Gate bridge to Big Ben — have been created with 3D printing tech before, bringing an entire city to life is quite a unique and remarkable feat: the created model of Stockholm is a full 157 square foot (scale 1:1000) in size. The Stockholm project used two Stratasys printers, running 24/7, seven days a week for six months before they finally fulfilled their remit and were given a vacation from their day & night job of creating the models.

Prior to the Stockholm project, originally commissioned in 2005 by the city, the company had been using only traditional means to create their models – paper, glue and wood combined with the blood, sweat and tears involved in manual, intricate labour. The fundamental reasons for tipping the scale to 3D printing’s side were the continuity and real-world reminiscent features of the commission – the model of the city was to be updated and revamped according to actual changes that take place in the infrastructure and city image every half a year. This meant that putting long hours into wood carving and other phases of the traditional process wasn’t an ideal or relevant approach to be used in this case.

Jumping on the 3D printing train from the traditional methodologies wasn’t something that could be done overnight though – the physical, technical and mental factors, as well as changes in general attitude, approach and the operating model required a realistic transition phase. In Mitekgruppen’s case, that period lasted for a full nine months, during which time the project team took a crash course in CAD modelling, 3D printing tech, new SW and other required tools that would enable them to get the job done as efficiently and smoothly as humanly possible.

The effort the team put into learning the ropes of the 3D printing world didn’t go to waste even after finishing the base model of the city – the company currently starts every project with 3D printed models and prototypes, after which their current weapon of choice – a Stratasys Fortus 250mc – is also used to make some of the actual end-products in addition to other manufacturing techniques and technologies such as laser cutting and milling.

The model of Stockholm is currently not on display anywhere — but it is being prepared to be showcased in a yet undisclosed location (in Sweden of course).
