Activity: Cardboard Puzzle Pieces

Introduction to Digital Fabrication

There are three fundamental types of fabrication: additive, subtractive and formative.

Additive

Adds material

Subtractive

Removes material

Formative

Molds the material

Crafting techniques follow similar fabrication concepts

Knitting

The yarn is knotted (added) row by row to create a knitted fabric.

Carving

Wood is carved out on specific areas to create the design and texture wanted.

Resin

Resin is placed in molds to achieve specific shapes.

Introduction to Additive Digital Fabrication

This workshop is focused on additive fabrication. Additive manufacturing or 3D printing processes build objects by adding material one layer at a time, with each successive layer bonding to the previous layer until the part is complete (formLab).

Depending on the technology, the 3D printer can deposit material by selectively curing liquid (SLA), fusing powder (SLS), or depositing material (FDM). Each additive fabrication machine is designed to use a specific material.

Selective laser sintering (SLS)

Fused deposition modeling (FDM)

Advantages of 3D printing

Digital fabrication can create unique and precise pieces.

It offers a range of advantages compared to traditional manufacturing methods.

3D printing allows for the design and printing of more complex designs than traditional manufacturing processes.
3D printing can manufacture parts within hours, which speeds up the prototyping process.
3D-printed parts can be created from tailored materials that provide specific properties, such as heat resistance, higher strength, or water repellency.
3D printing machines continue to become more accessible and affordable.
There are many other advantages; please keep reading here.

Main Concepts

Layers

The concept of layers is the foundation for additive fabrication, as the machine deposits material layer by layer to create 3D shapes.

Let's reflect on cardboard puzzle activity

How does the thickness of the cardboard relate to the number of layers the object has?

The amount of layers depends on the layer height. In this case, the layer height is the thickness of the cardboard. The thicker the cardboard, the fewer layers we would need to create the object with the same height.

2. What transformations can we do in each layer?

As we glue the layers together, we can rotate them with respect to the shape's center and scale them. During this activity, we noticed that some pieces are smaller than others. The stacking of rotated and scaled layers can create unique and cool designs.

Showcase your piece!

What approach did you take to create your cardboard vase? What was challenging to do?

Activity: Being the Machine

Let's reflect on being the machine activity

What was the most challenging part of the exercise?
Are you satisfied with the final 3D outcome? Why, or why not?
What material properties did you notice while constructing the pieces?
What would have happened if the nozzle of the tube had been bigger/smaller?

More about FDM Printing

Material

The extruded material from the nozzle.

We need different steps in the FDM process depending on the type of material. The choice of the material dictates the toolpath design.

Examples:

Plastic (PLA, TPU, etc.)
thin filament
small nozzle
heated nozzle/bed

Clay
large nozzle
thick coils
air dry

Glass
large nozzle
heated nozzle
printed in kiln

Chocolate
thin filament
heated nozzle
room temperature

Nozzle Size

An important parameter that determines the thickness of an extruded line.

Plastic printers (left) use small nozzles and multiple segments side by side to create a single wall, whereas clay (middle) and cement (right) 3D printers use larger nozzles that can construct the walls in one pass:

0.4 mm (1/64")

82.MOV

6 mm (1/4")

BIG!

Bakers use different nozzle sizes and shapes to create specific designs with different resolutions.

Toolpath

The 3-dimensional trajectory that the nozzle follows to construct the object.

Designing the toolpath of the printer gives us more control over the outcome of our print. We can fine-tune extruded material amount, nozzle speed, and its position for every point of our set of points.
