PROJECT 2: Held // Reverse Engineering (BUILD)

Project 2: Held 3D Modeling 

Assigned: May 21
Due: June 4

3D printing research & Concept design due: May 28

3D Printing Research & Concept

Begin thinking about 3D printing as a tool for designers, whether for prototyping or a final result. 

Research: do your own research on 3D printed design objects. Consider why each of those objects have been 3D printed and not produced by a mold, or other fabrication techniques.

Begin a new Google Slides Presentation and include the following in the first 2 slides:

Three 3D printed precedence, this can be example images to help explain the logic of your concept, or simply works that you are inspired by and why.

Consider the following to write about:

• What interests you about their work or method of using 3D printing
• How have they presented their designs/projects? 
• What type of 3D printing is it? (layer based, resin, powder based print, custom material work, etc).
• What material are they working with? and why?

Link your presentation on your next blog post before Tuesday May 28 by 1:00pm.

3D modeling (in progress) due: May 28

Assignment Description:

Manually digitize your object, or begin 3D modeling your object and their components using real measurements. Take measurements from either 1) your laser cut object (for where the held will sit into, you may also use your pre-existing 3D models as well), or 2) take measurements of your physical reverse engineering object using a Caliper, from which you will create a digital twin in Rhino.

• Structural support of a 3D printed object.
• Consider that cantilevering edges or offhangs larger than a 40 degree angle from the vertal plane will need to be printed with sacrificial supports. Will you be able to cut the supports off of your surfaces? Will you be okay with the remaining texture.
• Will it be printed in several parts and then assembled? Such as pins, joineries, gears.
• Consider the possibility of incorporating non-3d-printed materials (i.e. hardware, wire, laser-cut wood/acrylic, etc.).
• Structural support of a 3D printed object.

Option 1: The Held
The holding and the held. Imagine project one (laser cut object) will be a nest to hold project 3 (3D printed object). Together, they are welcome to create a functional design object, such as a lantern, or be an expressive creation of your choice. Now that you have a nest, podium or 'holding' component created as project 1, we will spend project 2 3D modeling the item that will be 3D printed in project 3.

 
Assignment Breakdown:

1. Begin 3D modeling your designs based on the feedback provided
   
2. Using 2D and 3D geometry functions, re-create your objects geometry to-scale (inputting dimensions as you enter drawing commands). Your Held object should have relationship to the holding, both conceptually, but more importantly, geometrically. How will it fit in your holding object?
   
3. You may use your previous 3D model to aid your progress. However be sure to create a new Rhino file for this project. You can do so by 'saving as' and deleting the workflow created in project 1.
4. In the case that there are new joineries to resolve, organize your digital model by using layers. Be sure to create an object with enough complexity to compare to a mechanical object.
5. Consider 3D printability as a parameter when designing:
6. Document your progress digitizing your object in a new post on your process blog, due at 1:00 pm Tuesday May 28. (include your 3D printing research in the same blog post).
   
7. Include images (screenshots) of your model in the blog post.

Reverse Engineering Assignment Breakdown:

1. Using your digital calipers, take measurements of your object's components (as you go).
   
2. Using 2D and 3D geometry functions, re-create your objects geometry to-scale (inputting dimensions as you enter drawing commands)
   
3. Aim for dimensional accuracy of one-tenth (0.0) of a millimeter.
   
4. In the case of reverse engineering, what will you change about the object before printing it? How will you make it your own?
   
5. Consider 3D printability as a parameter when designing:
   
6. Document your progress digitizing your object in a new post on your process blog, due at 1:00 pm Tuesday May 28. (include your 3D printing research in the same blog post).
7. Include images (screenshots) of your model in the blog post.

Enjoy the process!
