3D MODEL in progress due: May 30

3D Modeling

Continue 3D modeling for project 2. Email me a link to a new blog post by 12:00pm Thursday May 30th, showing screenshots and written updates of your 3D modeling progress. How is the modeling coming along? What are you finding challenging?

Project Development

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,
   
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
7. Include images (screenshots) of your model in the blog post.

Enjoy the process!
