A note on implementation
There can be many barriers to get students to 3D print. You must first start out with a three- dimensional virtual model that you can send to the printer. This requires knowledge of Computer Aided Design software, which can be hard to understand how to use if you have trouble visualizing information and understanding spatial relationships. It can also be very difficult to understand how to translate an idea in your mind straight to the computer without any tactile representations.
You may also want to consider how to implement the Next Generation Science Standards in the design challenges you give your students, as 3D printing lends itself well to the Engineering Design process.
Below are some suggestions on how to better implement 3D design and printing to account for learner variability.
Start with your idea and prototype!
Some students may start out with a rough drawing of their idea and head straight to the computer to create a three-dimensional model.
Here are some other options for your students:
Start by making a real-world prototype out of common craft materials such as:
​
-
foam core board
-
clay/ play-doh
-
construction paper
-
cardboard
-
hot glue
-
pipe cleaners
-
wood scraps
-
wire
-
pom poms
-
etc!!!

Create a 3D Model
Your next step will be to create a 3D file or virtual model of what you want to print.
You can use software such as TinkerCAD , SolidWorks, OnShape, etc..
You might also want to consider
-
using a 3D scanner
-
getting help from an adult or someone more knowledgeable with the software to translate your mock-up into a virtual model
-
take measurements from your model using a tape measure, calipers, or a virtual measuring app that can read the measurements to you
-
create a raised image by starting with a 2D file and extruding it
Iterate!
Don't forget to iterate!
​
Once you have successfully 3D printed your design, take a look/feel and see if it satisfies your design constraints and needs.
​
You may need to change dimensions, the printing orientation, or change the surface of the print.
