Editor's Notes
- Hi everyone and welcome to the workshop. My name is Michelle Folkman and I am here today to introduce you to some entry-level concepts and tools for 3D design and modeling. One of the aspects of making is 3D and 3D printing, so we thought what we should do is introduce people to a way that you could try it yourself. About me : I have been 3D modeling for over 20 years. I started by making architectural renderings, and I did some 3D animation. But I discovered that modeling for 3D printing is a little bit different than what I am used to, so I am learning along the way, the same as you. Which is a very maker thing. Can you all see the pictures? Does anyone know what the item on the left is? What I am trying to show you with these pictures, is that 3D modeling can be simple - like the jack on the left or complex and organic, like the foot on the right.
- A great way to get started with 3D design is to use existing projects and modify them. There is a wonderful resource called Thingiverse, (http://www.thingiverse.com/) where people upload 3D models and share them with the world at large. There are tons of free models you can download and print. What we are going to do today is take one model and customize it using Tinkercad. At the end you should be able to take a model that you get from Thingiverse, and personalize it using Tinkercad. Tinkercad is free - but you do have to create and account http://www.tinkercad.com We will build in some time for questions at the end. This is being recorded and it and the slides will be available
- Before we do that - I don’t want to bore or overwhelm you, but 3D comes with its own terminology and concepts. I feel like I should at least mention them, so I am going introduce a couple of these and at least say the words so you hear them, do not worry about remembering them. Lets talk about what I think of as space in a box – virtual space, which is what you deal with when doing 3D modeling. Whether we are aware of it or not, a lot of us are used to looking at computer images in a 2D space, a flat space. One method used to describe space is the Cartesian Coordinate system, maybe you remember it from geometry class (don’t panic, this will not be on the test) 2D space is described by X and Y like on the left. X is left to right and Y is top to bottom. Now with 3D we move into Z space - like on the right (show movie). The important thing for you to take away is an appreciation of 3D modeling as 3 dimensions – like I said, how I think of it is space in a box.
- Like I said, what we are going to do today is take a model from Thingiverse and customize it using Tinkercad What we are going to do today is take one model and customize it. Steps : Go to Thingiverse.com → find a model to alter --> Click download this thing – Page goes to the bottom--> right click → copy link address In Tinkercad To start click Import -->URL → Right click - paste address http://www.thingiverse.com/download:237283 Of course an alternative is to click on the image and download the object and import the file into Tinkercad
- If time - open Makerbot software and demonstrate set-up
