In order to 3D print a model of one of your glasses, you will need to export it as an .STL file.
To do so you can follow these steps from Rhino:
Here are some screen shots showing the settings described above:
This file is now ready for 3D Printing. The monitors in the 3D printing lab in Bank building can you help you with the next steps.
I know there was some difficulty getting the renderings of the glasses to look right. I did some research and it looks like the newer versions of Keyshot require a slightly different strategy to get the glass to look right. In my video I show making separate “bodies” for the glass and the liquid. This is done to avoid interference between the glass and the liquid where the surfaces are occupying the same space. The extra step is to separate (using explode or extractsrf) the top of the liquid – that would make contact with the air – from the liquid that would make contact with the glass. There are additional settings that need to be configured for each part. See a full explanation here:
Here’s a quick test rendering I did:
Another feature that is relatively new to Keyshot is a setting called “transparency distance”. This setting is found on both the liquid and glass(solid) material and if you are trying to render a colored liquid it will be important to understand. Essentially, transparency distance can be understood as a color that correlates to the thickness of a part. If the part thickness is equal to the transparency distance, the material will be the color assigned to the transparency distance attribute. As the thickness decreases, the color becomes lighter and less saturated, and as the thickness increases, the color becomes a darker and more saturated. You can see a nice overview of this here:
Some more detailed and technical discussion around this topic can be read in this forum post:
Part 3: This Video demonstrates how to do a basic rendering with Keyshot, including how to set up the kinds of materials you may want to use for this project.

Commands used in this video:
Part 1: Software
Make sure your laptop is set up with working versions of Rhino and Keyshot.
Part 3: Glasses
Working from the brief for Project 1: Glasses, create the following content:
1. Development Sketches
Sketching is versatile tool for a designer, and is particularly helpful to resolve forms and solve modeling challenges when working with 3D CAD. Use sketching to develop the initial concept and form of your glasses’ design. Sketch on 8.5” x 11” sheets of paper. Scan or take legible photographs of the sketch(es) that guided your modeling. We recommend using Photoshop to clean up this image. Bring your sketches to class next week.
2. Rhino File
Your Rhino file must satisfy the following criteria:
Put this file in your personal folder on the Google Drive. Name this file Lastname_Glasses.3dm
Include 2 Renderings of your glasses:
Your renderings must satisfy the following criteria:
Include a screenshot of your revolve curves with the control points turned on. Your screenshot must satisfy the following criteria:
Write a brief text description of your design proposal. Your description must include the following content:
6. Google Doc
Create a google doc that includes all of the content listed above, in the order indicated below:
Name this file Lastname_Glasses. Save this document in your personal folder on the Google Drive, and add it to the “Glasses” assignment folder. To do this:
This is how many assignments will be collected.
