The Prudence Project

Whenever people think about 3D printing, they mostly think about desktop 3D printing. Mostly. With the Stacker, Blackbelt and other large printers the world is slowly opening up to larger size prints. But sometimes we come across a print that is just huge. Think: Almost 2 meters huge. Enter The Prudence Project by Mikrotvornica from Zagreb, Croatia, made with colorFabb PLA Economy.


 The full sized print (190cm), human for scale

Prudence is a sculpture produced for contemporary artist Abigail O’Brien from Dublin, Ireland. “Last November, the RHA (Royal Hibernian Academy)  presented Abigail O’Brien RHA, Prudence and the Game of Golf in the RHA Ashford Gallery, a photographic, sculpture and sound installation. Having completed Fortitude, The Collector, 2005 and Temperance, Oatfield Sweet Factory, 2009, Prudence is the third body of work in O’Briens series, The Temporal (Cardinal) Virtues, which are Fortitude, Temperance, Prudence, and Justice.”  

Says Marko Salopek of Mikrotvornica: “After the initial contact with Abigail and acceptance of our offer we started with the work. The request was to 3D print sculpture of a female golfer with total height of 190 cm. The STL file we were given was great but since it was produced from 3D scan there were some parts of the model that needed to be repaired and removed to give her that desired look Abigail requested. After we completed 3D model repair, we decided to build our own semi-large size 3D printer to help us 3D print this sculpture. Nikola was an architect in constructing our custom made 3D printer (400x400x350 mm – CoreXY build). Big digital 3D model was cut into 21 pieces at the most optimal places for easiest 3D printing avoiding any support. Also each individual part was optimized for easy assembly and gluing. They were sliced and 3D printed on our Modax3D Core 400 3D printer using exclusively colorFabb material.”

Test models

With PLA Economy Marko, a long-time user of colorFabb filaments, had found a great material that has proven to be very reliable with large print jobs. He continues: “To finish the physical model we used high gloss surface finish as requested by our client. Several layers of syringe putty was applied to remove any imperfections and layers in 3D print and of course lots of hand sanding after every layer. Later on we applied primer paint and finally high gloss paint varnish for the final look.”


So far they have made 3 large sculptures of Prudence and total of 15 small (30 cm in height) versions. Below is a short summary of the Prudence in numbers:

  • 21 individual parts glued together
  • total of 17.526 grams of colorFabb PLA was used (in our version 3)
  • total of 453 hours print time (in our version 3)
  • variable layer heights from 120 microns to 300 microns depending on the part of the sculpture and the version of the sculpture (big or small).

About Mikrotvornica

Mikrotvornica is a young startup company founded in Zagreb, Croatia by Nikola Blažević and Marko Salopek. Interesting thing is that Prudence project was a main reason they started Mikrotvornica. Before the project, both of them were working on their own individual ventures in 3D printing. Working on the Prudence project made them realize they worked very well together and decided to join forces.

Now, almost a year later, they have grown into young startup with strong foundations and great potential for growth. In Croatia we started local brand named 3DPrintaj. Under that name they bring everything 3D printing related to the local market. From 3D printing services to 3D modeling, 3D printer and material shop as well as education (as elsewhere in the world, educational sector for 3D printing is growing fast in Croatia).

Regarding their international efforts, Prudence remains our biggest project so far. With that project Marko and Nikola realized there is great opportunity in 3D printing art. That is why they are now actively looking for agents across Europe to connect us with artists who are willing to work with us on their art projects. Interested? Contect them here.

About PLA Economy

It makes sense they chose PLA Economy for their project. It is a highly popular filament used for bulk projects by many of our users… and ourselves.

PLA Economy is a fantastic PLA grade which we launched in November of 2016. Initially we released four colors: white, red, black and silver. Recently added the always popular Dark Blue, which is similar to our very own Ultra Marine Blue that we offer in our portfolio of PLA/PHA filaments.

PLA Economy offers a great value for your money. One spool consists of 2.2kg of filament for a dirt cheap price of a little over € 35 (ex VAT and shipping). It is a different grade than our range of PLA/PHA, but we guarantee the same colorFabb quality. Our filaments are readily available from our webshop. You can use the standard PLA settings if your printer has these pre-defined and these should work fine.

You can also opt for the PLA Economy Value Pack: order four spools as a value pack and receive an immediate 10% discount!
