System Engineering Project 2

The project's prototype enhances an existing inkjet food printer called EVEBOT printpen, to solve the limitations of the EVEBOT being not able to print on curved surfaces without touching the surface.

Domain: Cake

Objective of system: To print at the curved sides of a cream cake 

Before coming up with this system, a few problem statements and systems were conceptualised first, based on the project's specification. 

However those systems are not created due to factors such as: 

• Technical feasibility of the system in the given project timeline
• The needs for such systems does not exist. 

An initial CAD (Computer Aided Design) was modelled our tin SolidWorks. A prototype was quickly produced using a 3D printer to test feasibility of the system.

After testing the initial prototype, a more refined version is prototype was produced using a 3D printer and a laser cutting machine. 

A few more iterations were made based on users and stakeholder's feedback to produce the final prototype as the MVP (Minimum Viable Product) for this project 

Material used: 

• Acrylic sheet for base plate 
• PETG for bendable guide ruler 
• ABS for turntable

1. Fixed the bendable guide ruler onto the base plate according to the size of the cake.
2. Place the cake on the acrylic base plate.
3. Lean the EVEBOT printpen at the side of the bendable guide ruler, and move it across the ruler to print the decoration onto the cake.
