Using 3D Printed Interlocking Metals Was A Design Challenge

October 19, 2017 8:34 pm

This new ring launched last week but it took a few iterations to get it right. This was my first design using Shapeways’ 3D printed interlocking metals. The Gimmel Ring is a puzzle ring that has three separate bands. There is a heart on the center band. The top and bottom bands each have a hand. They loop together like links in a chain. When you arrange them correctly the two hands clasp the heart. The Design Shapeways’ design rule when using 3D printed interlocking metals says that the different parts have to be at least 1mm apart. This posed a challenge with this ring. The parts would have to be closer than 1mm for them to fit together snugly. On the other hand, if the pieces were too close together, they may not fit together at all. So first I designed the three pieces together to make sure the clearances were tight. In this case, I made them only about 0.2 to 0.3mm apart when fit together. The tolerances on these kind of parts are around that range, so I figured it would be close. The plan was if my initial prototype did not fit together, I would at least know what areas were too tight and could redesign them. After designing the three pieces together, I then separated them in the 3D model. I tried to separate them in a way that they would still go together, but were spaced apart more than 1mm. The first time I did this, I was not smart enough to put my own puzzle together. The Prototypes Gimmel Ring with the bands separated After I got the first prototype, the
