Hi. I am a Senior student at Principia.I have taken several classes in the engineering department such as; Mechanics of Materials, 3D Printing Technology, Mechanic dynamics and Circuit analysis. Please feel free to drop me a line Webpages: LinkedIn.


Taking Open source 442 was an enlightening experience as it is giving me exposure to explore 3D printing. This was my first time doing printing and it was interesting to witness the development of each project, from the build up to when the first print was created. There was a lot of trouble shooting done in order to ensure the printer works. It was amazing to have hands on experience on Jellybox1 and 2. The 3D print community was eager enough to put some work in the project and therefore the energy transferred to everyone. 3D printing would be helpful in career fields such as companies that use nanotechnology.

Biography[edit | edit source]

Julie Mirambo is a senior student in Principia college pursuing Engineering. She has prior experience in the engineering field having done classes that required software like: AutoCAD, Solid works, Python and of recent 3D printing. She is also well experienced in the chemical field especially lab techniques such as chromatography and using a mass spectrometer. She has been part of a solar car which designs and diagnoses efficiency of moving racing car. Through the course of the years she has taken part in various projects in her career field as well as going for internships which expanded her thinking scope.

I have also take part in internship at Midwest Sterilization Corporation which exposed me to the real world of Engineering technology.

Projects[edit | edit source]

House Project
Housespicture.jpg The first project was to build the house and was the first indication that the printer is working efficiently.
My First Print
Ugly.jpg My first print was the ugly duck. I was still adjusting the z height and therefore didn't explore that much in thingiverse.
Jellybox Replacement Part
Replace.jpg For this project, I replaced the fan since jelly box 1 doesent have two fan system. The object came out with an overhang due to the placement in Cura.
Blender Exercise
Snowy.jpg This excercise was meant to learn about blender. The videos assigned in class was helpful to learn about rotation and scaling and transfering the file to cure for slicing.
FreeCAD Exercise
Prp.jpg We learned the basics of FreeCAD, and Design a fan propeller.

OpenSCAD Exercise
Cubecoin.jpg The fundamentals of OpenSCAD were covered. For the assignment, we created this coin holder and modified a rock wall holder. Although this tool is undoubtedly simple to use if you have coding skills, I find it to be really challenging to utilize. That it doesn't tell me what's wrong irritates me. It simply places a red dot someplace, and when I check that line, nothing is wrong.

This was a print created in the process of learning how to create Open scad models. With the help of the professor, I was able to write down codes that enabled this print to be made. This print took less than 1 hour to be completed.

Education Science Project
Drinking Bird
This was an educational toy that explained chemistry disciplines such as heat of vaporization, vapor pressure and condensation. When temperature increases the liquid in the drinking bird goes to the head of the bird hence making the bird’s beak slant and later on the bird swings back and forth. Several attempts were made to make the drinking bird because the support kept breaking the structure. The final prototype was successful when the prototype was printed laying horizontally.

Extruder modification
The extruder of the jelly box was modified in such a way it could be able to hold a syringe that prints chocolate. The extruder was modified using blender and a torus attached that would be used to enclose the syringe . Several attempts were made in blender and the file also was edited using mesh lab to close all the meshes. The initial print came out too thin with the torus shape being too small to insert the syringe.

This is my second prototype for the chocolate extruder.
The first design could not hold up the chocolate syringe as it would drop when the jelly box was in use. Three cubes with holes around were used to attach the object together into place. There were several things that still need further modification for instance the nozzle was way below the fan which could be problematic to the prints. The chocolate syringe was then attached to a laser cut lid so that it could have support on top.
