I got a chance to play with Autodesk's 123D application. I spent sometimes to get myself familiar with 123D, and found that it was very easy to use with a lot of features that I could use to create a professional quality 3D models.
This hands-on tutorial is written for anyone who want to make 3D Print.
In this tutorials, you will learn to use 123D through a series of hands-on exercises.
After reading this tutorial, you can use 123D to visualize designs of the things that will actually be built. You will be guided through the basics of 3D manipulation in 123D, and the principal ideas involved in displaying complex 3D objects, and will be ready to create the simple objects that will get you that first 3D Printing object. You will learn how to save and export files directly from 123D program to send to fabricator, such as "Free 3D Printing" Group or anyother 3D Fabricators.
On the way, you get to do something you can see with your “looking glass”, you can create 3D parts, robots, objects and subjects of any type.
- Sketch/design the models.
- Getting to know the 123D application.
- Use 123D application to create various small 3D models of robot's parts, ears, eyes, shoulders and hands.
- Combine (join) these parts together into one single piece.
- Submit the model to the Instructables' "Free 3D Printing" Group, or to 3D Print fabricators.
By combining (joining) small individual 3D Models together, either from the same project or from different project. We could save time and do not have to submit each part individually. And we could avoid waiting for each part to be delivered many times before using them in the project(s).
Another benefit of combining (joining) models together is that if the combined model has the size which is smaller than 3x3x3" cube, we could submit the model to "Free 3D Printing" offer to have it made if you are not in a hurry! But you need to write up an instructable and sign up as a member, to qualify.
Not only you could use this methods for "Free 3D Printing" here at instructables, but you could also apply the methods with your 3D model to be done ( but not free) at Shapeway, Ponoko, etc. (which allow you to print a larger 3d model for example a model with a footprint of 4x6", etc.)
Step 1: Rough Sketches
I designed the ears, eyes, shoulders, and hands for my robot project, Put 40 LEDs and Brain into Robot Head.
All the parts are only decorative pieces for the robot, only the eyes that I may want to put the 5mm diameter LEDs inside.
And the parts will be fit into the round existing openning, for example eyes will be fit in 10 mm diameter openning, and ears will be fit in 20 mm diameter openning. And both shoulders and hand will be fitting into round Acrylic tubing with 1" (25.4mm) OD (Outside Diameter) and 7/8" (22.225mm) ID (Inside Diameter) . So the designs will somehow have the round plug attached to one end, as shown in the sketches below.
When I was working on the new project, I usually transfer the idea I had in mind into the paper. Sometimes I only doodling on the napkin, just like other designer/inventor did!
Later I would refined the napkin sketches to realizable design and something that make sense. The other consideration is that the design should compliment the existing object.
Sketches below (no. 1, 2, and 3) are not really "napkin sketches", they were refined sketches. At this stage all the dimensions are in Millimeter.
