Webster: A Geometric Pattern Weaving Machine
We are three students from California College of the Arts in San Francisco in the Architecture program. This studio is called Creative Architecture Machines and is taught by Jason Johnson and Michael Shiloh. Webster is a geometric pattern weaving machine that takes inspiration from Islamic tiling, geodesic dome construction, weaving machines, and conventional 3D printers. This 3-axis robot was an exploration in the geometric control of stepper motors, the texture variability of hot glue extrusion, and weaving facets through script-generated density difference and form repetition. Harnessing the structural capacity of the glue texture, the movement of the z-axis motor, and the variability of the weave, Webster was used to rapid-prototyping domes through an additive web-like process.
Please see the attached video for more visual information on the process and final product. If you are interested in more information about the process or have any questions regarding the setup please feel free to contact us. We would love to hear feedback or suggestions as well.

Step 1: What You’ll Need
Step 2: Building The Base (X and Y)
Start at the bottom and build up.
Cut out a 19″ x 23″ piece of 1/4″ Plywood. This is a base for the machine to rest on.
Cut out the structure for the X and Y bed, a 19″ x 19″ x 1/4″ D Plywood Square with 13″ x 13″ hole cut out of the center.
You’ll need to cut out 4 sets of holes at each corner. Please refer to laser file attached.
Cut out remainder of pieces on laser file. Please refer to image for assembly.
Screw “A” pieces into the corners to secure wooden dowels.
Place Aluminum rods down perpendicular to wooden dowels.
Make sure you slide 2 linear bearings on to each aluminum rod before securing it down.
Sandwich aluminum rods between “A” and “B” pieces. Do this in each corner.
Add the vertical “C” pieces in 3 corners. The fourth corner will have two vertical “D” pieces that sandwich the X motor in place.
Run a screw with a Nylon spacer over it through each pair of “C” tabs.
Place the remaining two aluminum rods perpendicular to the ones directly below them. Make sure to slide one linear bearing onto each of these before securing down. Please refer to image to see how the aluminum rods attach to each other.
Now you attach the bed. The linear bearings need to be directly across from one another and the held in place by the bed.
