About Project

The 0.8-meter high giant matryoshka doll model is made with SLA 3D printing technology and then electroplated to wear a copper coating. Although it looked like a Russian nesting doll, it's just indeed a gourd-shaped doll with inner supporting structures.

SLA technology can achieve very good accuracy, surface finishes, and details. Machines with large build volume enable large parts. In FacFox, our largest printing volume in one-piece is 1700 x 800 x 600 mm. Furthermore, there is a wide range of photopolymer materials available that can build parts with different characteristics. Certain SLA materials can mirror the characteristics of engineering plastics over a short period of time, there are also rubber-like resin and clear resin that can be used for aesthetic and validation purposes.


  • Step 1: Although our largest printing volume is 1700 x 800 x 600 mm, we did not print the doll in one piece considering its structure. The neck of the doll is relatively narrow, so the air pressure would cause transformation if we printed it upward in one piece. To minimize the possibility of failure, we raised the solution of splitting the model and printing the upper part bottom-up, then glue the two parts together.
  • Step 2: Slice the models after splitting and then print it with SLA 3D printing method, using SLA Tough Resin. Tough resin (SLA) has better stiffness and impact resistance than generic resin, and produces parts with improved mechanical properties.
    The facial and garment features of the model look as if engraved outwards, where layer thickness should be kept in mind. The amount of minimum detail is very important to keep in mind when designing for any 3D printing technology. The minimum detail depends on the technology, as the smaller the layer thickness the more accurate will be the detail.
  • Step 3: Post-processing like cleaning, post-curing, polishing, electroplating, and painting.
