Additive Manufacturing Project - Basic Cube Example
Tips:
Keep your design simple to start, and iterate to make more complex features.
Don't be afraid for a print to fail. It is better to try and make a mistake earlier than letting the fear of failure get in the way of trying (I'm not worried about wasting material on multiple prototypes 😀)
Material:
Wooden Blocks - For Prototyping
Makerbot Sketch 3D printers with PLA material
Onshape
Project Instructions
Overview:Â
Transitioning from fully conceptual designs to manufacturing a product inserts many additional constraints depending on the method of production. Additionally, 3D printing is a quickly growing and expanding industry that provides many new possibilities for customized production. Using the 3D printers in class we can produce an excellent prototype of small children’s toys that a business could theoretically bring to market. Your task is to design and produce a toy.Â
Problem Statement:
The objective is to design and produce a 3d Puzzle that a child (5+) could play with and solve.Â
Problem Description:
The puzzle should have interlocking components and be complex enough to present a challenge to the user. I recommend you start with a puzzle cube, as it is the easiest to design and build. If you would like, you can create a more complex piece resulting in a pyramid, complex shape, or even an action figure.Â
Constraints:Â
At least one dimension greater than 60mm
Minimum of 5 unique pieces
The pieces must interlock in a way that the completed puzzle does not simply fall apart when handled
Requirements:Â
Manufacture your model using the class 3D Printers
.MAKERBOT file must be submitted to print queue for each part by project deadline
You may manufacture your product more than once to improve if you use time appropriately
Engineering Drawing as a single PDF
Assembly Drawing (2 pages)
Assembled and Explode view
Bill of Materials (BOM) table with correct quantities (Identical parts should be consolidated)
Part Callouts matching the BOM
Text instructions as required to clear up confusion
Part Drawings (Min 1 page per part, 5 pages Minimum)
Each Part dimensioned with callout matching BOM
Each Part should have all 3 Orthographic Views and a shaded Isometric View
Make sure someone else could recreate your parts if given only your engineering drawings
Avoid over dimensioning - Use appropriate drawing annotations to reduce clutter
Use hidden lines as needed
