Homework Discussion

Let’s go around the room and discuss your Design Notebook entries for this week.

Trend: 3D Printing

Be your own souvenir

Desktop Manufacturing

• Laser cutters (subtractive)
• CNC routers (subtractive)
• 3D Printers (additive)

Subtractive vs Additive Processes

• Subtractive manufacturing processes ‘cut out’ the object
• Additive manufacturing processes ‘build up’ the object

Numerical Control Languages

• Laser cutters, CNC routers & 3D printers are controlled by computers through machine languages – CNC stands for “Computer Numerical Control”
• A common machine language for desktop manufacturing equipment is G Code

3D Printers

• 3D printers are similar to regular printers, except that they also move along the Z-axis
• Instead of ink, 3D printers usually extrude melted plastic, though other materials can be used as well:

Homework Assignment 7a (5 points, 1 point each)

1. Create a new page in your Design Notebook and give it a title reflective of the final project you’re thinking about
2. Give a brief description of your project idea
3. Include the category from the Sarnoff Collection you’ll be addressing with your project
4. Include a list of the specific item(s) you’ll be interpreting for your project
5. Make a list of possible references for your project

Assignment 7b  (5 points, 1 point each)

1. Read the 2013 TrendsWatch Report pp 13-17
2. Create a new page in your Design Notebook with the heading “3D Printing”
3. Take a look at some of the examples of 3D printing currently used in museums on p 17 of the TrendsWatch Report and write a paragraph about your favorite example.
4. Can you find any other examples of the 3D printing being used “in the wild”?  Jot down a brief description & a link to what you find in your Design Notebook.
