Week 1 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

3D printer

This week, we had two activities. First, applying 2D model on laser cutter using a software called " LaserWork " on wood sheet. Then, I manufactured 3D model using 3D printer with PLA material by using software called " Ultimaker Cura".

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Machines:

laser cutting machine for 2D model
PURSA I3 MK2 for 3D model

Softwares:

LaserWork
Ultimaker Cura 4.10.0

Materials:

plywood 3mm thick
PLA 2mm blue filament

lighted sorting hat

cup coaster of Marid washwishny shape

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

laser cutting speed and power values

Laser cutting Modeling:

In the begining, I searched about ".dxf" file on 3axis.com. Then, I imported on laser works software to modify it, set the right speed and power values which are 300 speed and 35 power for the speed cut, 20 speed and 65 power for the outer line cut and speed 400 and power 55 for the scan. After that, I saved the file in ".rld" extension and transformed to the laser cutter PC. In the end, I looked at the last preview then started the operation.

3D printing Modeling:

First, I wanted to manufacture the sorting hat of harry potter movie, So I searched about it as ".stl" file from thingiverse.com. Then, I imported it on Ultimaker Cura. the next step was modifing the dimensions, Temperature, adding supports and slice it.

Suitable infill, profile and supports

suitable Temperature for printing

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

For the Laser cutting:

open the flash memory on the laser cut PC.
open my RLP file
check the speed
watch the preview
prepare the origin position of the work piece
checking the focal length by using the " focus".
choose my file from the files
RUN

It was 1 min and 30 secs.

Here I used the speed cut cause, I just wanted Mark in wood not cut. Then, I used the deep cut to seperate the final model from the sheet.

Explain what the colors mean

For the 3D printing:

Rename the file with the printing details "PI3MK2_lighted_sorting_hat_55min_8g_blue.gcode"
put the file on the printer SD card
choose the file on the Machine and RUN

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

Marid Washwshny coaster

yes, actually my Instructor liked it and my colleauges said that it's nice, but it will be better if it was larger. Plus, I gave them my feedback on their beautiful choices for their pieces.

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

In the fact, it was hard to remove the support from the 3D model, I did my best to avoid causing cracks to the model. Plus, I had to redesign the model because the temperature was 215 not 200.

As for laser cutting, I wanted to scan the teeth above the mouth, but it didn't appear in the preview cause it wasn't close curve. The instructor helped me as we tried to change it to speed cut rathar than scaning and it works.
