ADDITIVE MANUFACTURING

Redesign Challenge​: Redesigning the Quadcycle Drive Shaft Assembly for Additive Manufacturing 

BACKGROUND

This is a redesign challenge project to internalize the applications of Design for Additive Manufacturing (AM) principles. An assembly that has already been manufactured using conventional techniques ( also known as Subtractive Manufacturing (SM)) is chosen and should be analysed to see how the manufacturing process could be improved by using AM. This is followed by fabrication of the assembly to demonstrate the functionality of the system.

METHODOLOGY

Phase I: Understanding an Existing SM-Produced Assembly of Components 

The Quadcycle is a powered four wheeled bike created by Professor James Contes (ASU polytechnic). As a team our objective is to re-design part of the drive shaft assembly of the vehicle by applying Additive Manufacturing (AM) principles and create a functional prototype of the design object. This involves the reverse engineering of the chosen assembly to attempt to understand the functionality of each part in the original assembly.

Phase II: Redesigning of Assembly for AM Process and Fabrication

In the second phase we endeavor to redesign the assembly for additive manufacturing process and build the first design iteration model using FDM (fused deposition modelling) process.

Phase III: Analyze the Redesign for Increased Yield and Feasibility of Fabrication

In phase three, we analyze the previous model and make improvements in the design. Then we build the second iteration model.

OUTCOME

Applied principles of Design for AM and proved the technical feasibility and functionality of the manufactured part. Delivered a working prototype of the driveshaft built using FDM (Stratasys uPrint).

Literature Review of a Cutting Edge Problem in Additive Manufacturing

 

BACKGROUND

In order to be familiar with the current research on additive manufacturing the only way is to be able to sift through peer-reviewed journals and understand the processes mentioned. Hence a literature survey should be conducted to identify a problem and see what has been done in the world to solve this problem. 

.  .  .

OUTCOME

The major skill developed is to critically think of problems in cutting edge additive manufacturing. Ability to identify and define a problem and suggest possible solutions.

Scaffold fabrication is very important in tissue regeneration area of medical devices industry. Improvements in FDM techniques to accommodate fabrication of finer elements of the support structure would improve the integrity of the scaffold.
