00.13 Blue 3D Printing & Sustainability

Learning Objective: You will evaluate efforts to use 3D printing sustainably.

Essential Question: What role might 3D printing play in reducing the impact of plastic?

Your assignment (due at 20 minutes before the end of the period):

• Investigate sustainability & 3D Printing

Get started by:

1. Picking up your laptop.

2. Go to classroom.google.com and open 00.13 3D Printing & Sustainability

3. Read the instructions carefully and answer all questions within. Click Turn In when you are done.

2. Objectified documentary

* Industrial design & Mass production

* Extreme Users and why designers design for them

3. The Iterative Process & Prototyping

4. 3D Printing - when it was developed and its impact on the world

5. 3D Printing Methods - know what the three primary methods of 3D printing are, the basics of how they works, the benefits and drawbacks of each method, and how the methods compare to one another.

6. 3D Printing Materials for FDM - know the 4 main 3D printing materials we learned about in class, what their for, and best uses for each material.

3D Printing & Sustainability

Basic Laptop Rules:

1. No headphones (unless watching a video).

2. Only use the laptop assigned to you.

3. Carry the laptop by the base (not the screen).

4. Follow the laptop retrieval and return protocols.

3D Printing Technologies!

Laser Sintering

Subtractive Manufacturing: a part or model is built by starting with a raw block and cutting away material to leave the finished product.

• Form of Printer Material: ___________

• Basic Process: A laser fuses a powder one layer at a time, building the model from the bottom up.

Advantages:

• ____________________
• ____________________
• ____________________

Disadvantage:

• ____________________
• ____________________

Fused Deposition Modeling (FDM)

Additive Manufacturing: a part or model is built by adding material one layer at a time.

Advantages:

• Capable of fine detail
• Capable of printing in a wide variety of materials, including metal.
• Less post-processing as supports are not needed.

Disadvantage:

• Very expensive. No desktop models yet.
• Safety concerns require greater investment in safety equipment

Form of Printer Material: _______

• Solid filament is heated into a liquid and deposited onto a build plate by an extruder.
• The print is build one layer at a time - from the bottom up.

Advantages:

Stereolithography (SLA)

FDM:

• Affordable
• Well-developed consumer market - readily available.
• Capable of printing with high-strength materials (ABS).

Disadvantages:

• Some models require supports (waste material)
• Not yet capable of the kind of detail that other printing technologies.

Form of Printer Material: _________

• Basic Process: An ultraviolet laser is directed into a liquid resin, solidifying the model one layer at a time.

Advantages

• _______________
• _______________

Disadvantages:

• _______________
• _______________

The Marshmallow Challenge & Collaboration

SLA Advantages:

• Capable of fine detail and complexity
• Capable of printing quicker than FDM

Disadvantages:

• More expensive
• Does not yet have the variety of materials that FDM does.
