MetaMaterial Design (Plier)

Designing a plier with meta material!

Designing cells

Building and adjusting rigid and shear cells

Building the Plier

Setting stiffness to 50%, we started building plier’s main body

Touching up edges

I noticed that the edges of the plier are not smooth, so we designed triangular cells to smooth the edges

Slicing and Examing

Due to unknown issue, the edging and interior cells are not connected. I tried to fix the issue by slicing the model in different ways, but the issue still persists.

3D Printed Product

Regardless, the printed plier is able to convert the force and firmly grip small objects

Growing Hairs

Slicing an existing STL file into g-code file

After identifying a good position, modifying G-code file to add hairs

Visually examining whether the hair is propoerly added

Verifying the hair in G-Code

Confirming the setup with 3D Cura (due to excused absence, I did not get to print out the hairs)

Kerf Pattern with Fusion 360

Loading the provided triangular kerf template

Adding the connection circle sketch

Extruding a triangular kerf and a circle

Extending the sketch design to 4 triangular kerfs

Extruding the sketch to create the stl file

Final printed product

X-Bridge Replication

Replicating bridges was a collaborative effort, please click here for X-Bridge Replication

Resin Printing

Configuring ChituBox

We downloaded and installed chitubox from official website Then we followed Emory’s recommendation to configure the settings

Finding a sample STL file (Electro Gnosis from Genshin Impact)

We identified a “electro gnosis” chess piece from thingiverse

Modifying and Exporting the Electro Gnosis

We first scale the gnosis

Then we added a base and support to the gnosis

Finally, we slice and export the LCD-printer ready file

Printing the Gnosis

We first prepare the LCD printer and load the file into the printer

Our First Attempt failed, we suspect it was due to small size

However, with re-scaled size, the same problem occured

Seems like the base was not properly formed, we will try to fix the issue by not lifting the gnosis at all

Third Attempt

We not only made the gnosis stick to the ground, but also doubled both base layer and exposure time

Thank you!
