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)

use 3d printer to print a model and laser cutting machine to cut a model

3d printed eaglez

this eaglez is mainly used for decoration but it can be funny toy which can bite your finger by its movable beak.

i got this model design from thingiverse site

you can check it below

Eaglez thingiverse ↗️

wood bookmark

As I was inspired by reading, I liked using a special bookmark, so I decided to make it by using a laser cutting machine on wood plate.

i got this model design from 3axis.co site

you can check it below

bookmark 3axis ↗️

Tool Chain

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

ultimaker cura

this program is very professional it allows you to fully control on your model like infill, adhesion, resolution and show the time and weight required for finial product

LaserWorkV6

to be honest it's not professional program but it's totally free and it's good enough by using it i can make some changes like color, cut ,scan ,speed cut and scale

Machines used

prusa i3 MK3

i print by using PLA materials

El Malky ML149 CO2 Laser Cutter

i cut 3mm wood plate thickness

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?

1) 3d print model

i downloaded stl file from site mention above then open it by Cura then i chose type of printer and materials PLA.

then i adjust printing settings like resolution 0.2 ,infill 15% , shell 1 mm.

my model doesn't need any support or adhesion so i turned them off just i turn on skirt

then i click on slice and preview to check finial shape, time and weight

then click at save to disk to get the gcode file.

2) laser cutting model

i downloaded dxf file from site mention above then open it by laserworkV6 then import and click on the dxf file

then i adjust scale and size of it and start to move it to one side of sheet

start coloring different processes, they must divided to cut, speed cut and scan

then i chose suitable power and speed for each one.

then saving setting in rld file

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?

1) 3d print model

i send gcode file to printer by using usb flash drive and card reader.

then i chose color of pla filament so i remove old color by heating printer and select remove filament from setting options.

and chose color and by using Clipper small cut it with kind of sharp edge and click pull the filament.

i prefer that Turquoise color so i have changed it.

sharp cut

colors

adhesion

printing

2) laser cutting model

i send rld file to pc which linked to laser cutting machine and i check that every thing is right then click download to send file to machine.

then i put my sheet inside machine and fixed it,

then i move nozzle to sheet and select origin point and test power of laser by push pulse,

also i test the cutting area by pushing frame button then click start.

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

while preparing bookmark to laserworkV6 i found that the letters of my design is not thick enough to scan it, so i ask lab specialist to help me,

she suggested that i should delete letters and write it by my self by using fonts in the same program.

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

i think it will be the main different between laser processes which just can change once you change speed or power,

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.
