19. Project Development

Complete your final project, tracking your progress:

  • What tasks have been completed, and what tasks remain?
  • What’s working? what’s not?
  • What questions need to be resolved?
  • What will happen when?
  • What have you learned?

Project management:

  • Triage
  • Documentation during development
  • Demand- vs supply-side time management
  • Spiral development, DevOps
  • Serial vs parallel tasks
  • System integration
  • Finish quality

Responding to Project information

What tasks have been completed, and what tasks remain?

Complete tasks

  • Design Thinking: The user was known to identify that I need to optimize the process of decorating a cake, or other dish.
  • XYZ structure: A structure was designed for the XYZ movements of the 3D printer
  • Extruder: An extruder was designed to inject the decoration material

Remaining tasks

  • Electronic: An electronic card was designed that is the sum of an Arduino Mega + RAMPS 1.4, but it was not finished assembling it since we do not have all the components.
  • Software: We will work with the software to configure and calibrate the operation of the 3D printer
  • Testing: The operation of the 3D printer will be tested in 3 different processes.

In the list we can see our progress to 67%:

What’s working? what’s not?

Now we are working with the configuration of the software, we are not yet seeing the design for printing.

What questions need to be resolved?

We need to answer How can we print cold? In other words, cancel the extruder temperature control process since we do not need this process to print the decoration materials.

What will happen when?

We hope to find a way to solve the temperature control problem or cancel it, when we solve this the project will be almost finished.

What have you learned?

  • We have learned CAD design and assemblies that are very useful for machine manufacturing.
  • We have learned the creation of electronic boards integrating two current boards used in the industry that are the Arduino Mega and the RAMPS 1.4
  • We have learned about using the commercial supplies that we have in the medical or injectable area that helped us to have an injector of decoration material

Final Project: Advancing with the FAB20 3D Printer

The advanced parts are in the Software Section from Final Project

In this part of the development of my project we are in the software, working on how to modify the Marlin firmware to achieve printing without filament extruder temperature control.

As a summary, I have the following milestones to work on my final project:

  • Design Thinking
  • XYZ structure
  • Extruder
  • Electronic
  • Software
  • Testing

But in this week I will work on the Software Section from Final Project
