This is the second 3D model that our design team(www.plusplastic.com) has created and made publicly available. It is 3D-printable articulated robot toy ready to move straight off the print bed.

The Articulated Robot Toy is a playful exploration of FDM (FFF) 3D printing technology. Each module of the model can be printed as a single piece with articulated joints, eliminating the need for supports between moving parts due to carefully designed clearance gaps. If necessary, minimal supports can be printed, but they easily break away after printing due to moving joints.

To capture the distinctive features of rugby players, we've designed five positional models, emphasizing the large torso and helmet shape. The joints in the arms and legs are designed for a wide range of motion to replicate the dynamic nature of rugby players.

Articulated Robot Toy Features:

  • 5 FFF printable models / 1 SLA printable model
  • FFF printable models:
    Can be printed as a single piece including joints for arms and legs, allowing for movement.
    Can be used as an example of simple structural modeling with snap-fit ball joints, joints, etc.
    Gaps (tolerances) are applied for puzzle-like assembly of printed parts.
  • SLA printable model:
    Parts are separated for painting and assembly.
    Assembly and painting tolerances are applied.
  • NURBS model in 3DM format, STL file for polygon model

You can find detailed processes of modeling, FFF printing, and SLA printing in the following link(writtend in Korean).
