Combining Crowdsourcing and 3D Printing


Haarlem is a city located in the Netherlands and the capital of the province of North Holland. With a population of 155,000 it belongs to one of the bigger cities in the Netherlands and should have enough possibilities/resources for crowdsourcing a 3D Printing project, at least that’s what Max van Aerschot should have thought when he lauched his “Haarlem” cityprinting project.

Max van Aerschot, appointed to be city architect of Haarlem after fulfilling different projects, advised the town councils to focus on the east parts of the city. In his opinion, this part of the city has been forgotten since the late 60’s and citizens should be involved during initiatives for town planning. With co-building a city model, in the form of a 3Dprinting project, allows Max van Aerschot to show citizens what’s going on and how the future town planning of Haarlem looks like.

Visualizing, using city models, is an important tool for communication with citizens and additionally should result in more involvement in town planning. Gabriël Verheggen – Architect

Haarlem cityprinting project

After six years of walking around with his initial idea, Max van Aerschot launched the 3D printing project in collaboration with a few specialized companies and a lot of cizitens. The model would be built at a scale of 1:1000 and devided in 600 “puzzle pieces”. Making use of the crowd to create a city model is a wordwilde unique concept. Upon that, using the 3D printing technique makes it an extremely innovative crowdsourced 3D Puzzle project.

Crowdsourcing project.

Crowdsourcing is the process of getting work or funding, usually online, from a crowd of people. The word is a combination of the words ‘crowd’ and ‘outsourcing’. The idea is to take work and outsource it to a crowd of workers.

The choice for outsourcing the development of a cityprinted model of Haarlem to the crowd has several reasons. As told earlier it is a tool for communication and creating citizins involvement in town planning initiatives. Secondly, and probably one of the main reasons : 3D printing technique is a relative promising new technique however it allows Max van Aerschot “in collaboration with the crowd” to build the city model as it is nowadays at a scale of 1:1000. This project couldn’t have been done with old techniques due to a lack of time and financial resources. Besides the financial plusses, a lack of time is still a main reasons for crowdsourcing. The project couldn’t be a success without the crowd because of the lack of speed at which 3D printers work.

Using open-source data from the kadaster,  allows the initiatiors to devide the city plan in +- 600 pieces. This digital ‘puzzle’ is created in a way that every piece (18cm x 18cm) of the puzzle can be 3D printed with a (normal) 3D printer. This allows everyone who is owner of a 3D printer to participate in the co-creation process.

City printing

As pictured above, everyone who want’s to participate in the crowdsourcing project, can assign on a specific piece for creation. On the map : Blue = Free, Orange = Assigned but still needs to be print, Green= Printed.  After assigning on a specific “piece” participants will be provided with PLA (source for 3D printing) to print their assigned piece. The 3D printed part of Haarlem needs to be handed in at 3DMM (project – partner) to complete your role as a co-creator. After fulfilling the whole process, participants are rewarded with a place in the wall of fame and will obtain eternal fame on the first crowdsourced 3D printed city model.
