Week 3 I can call it the WEEK of Fusion 360 also like WEEK 2 but week 3 is focusing on the 3D sketches, 3d printing operation and related software, material, design, and implementation processes.
So, my assignment this week is a Pen & Pencil Holder that can be printed on a 3D printer machine (which is in our case called Prusa i3 machine), built in Fusion 360, and adjust other relevant parameters and settings in Ultimaker Cura software after downloading the file to STL format from Fusion 360.
I have been encouraged to make this type of pen and pencil holder shown in the following picture. Because I found it simple to have, use and decorate the desktop in the room too!
Model of a Pen & Pencil Holder
Fusion 360 and Ultimaker Cura is what I used during my 3D pre-printing process starting with Fusion 360 in designing / sketching the Pen & Pencil Holder model by sketching parts in 2D and using tools like extrude to make the model in 2.5D, Loft tool to enable me to plot an offset level To sketch in 2.5 D at a distance of a certain height, and in the end I used the PIPE parameter to fill in the lines and rectangular sketches that will serve as a pen holder or pencil body.
And end with Ultimaker Cura software to adjust the final settings such as infill, supports and others to determine the grams consumed and the time spent during the printing process, and this is done by slicing to review the final body. As we can see in the next pic.
Next, I used a Prusa i3 machine to 3D print the pen holder with PLA material and white filament color.

First, I sketched the design on Fusion 360 to design a model of the Pen & Pencil Holder using a Loft, Extrude, Pipes, Sweep and Shell parameters in order to get the desired final body.
Let's not miss that to use a parameter like Loft, I had to first activate the 3D Sketching by following the preferences section and selecting the Design feature, then activating the 3D Sketching of lines and splines.
Its preferred to go back to deactivate this feature after I finished the tools I used, let us don't miss that to make the software easier to use in various sketches afterwards.
Next, I customized the model via modifying its physical/material to a plastic material, then gave it a personalize appearance of white plastic.
After that, I saved the design file in STL format to open it on Ultimaker Cura software.
Then, I have to set the required dimensions and other parameters related to 3D printing process such as supports to be in everywhere, Infill for quality, and printing temperature which should be at 215°C.
Next, I sliced the process to figure out the time cost and grams spent by the 3D printer machine and the time taken was 85 minute and a 12 of grams consumed
Finally, I saved the file as G-code so the printer machine could recognize the design and start printing it.

Full steps involved in the design
The filament color that was installed on my Prusa i3 machine was green, but I want to use white, so I had to change the color of the filament first, then I uploaded the SD card on the machine, picked up the G-code file/design and directed the machine to identify the printed area to start the execution process. You may want to watch the next video to be more familiar with what I have done.
Next, I waited for a 85 minutes to finish the 3D printing process to remove the supports and get the final design / body you see in the following pics.

Yes, I asked the lap specialist about the depth of the slots/grooves before I used the machine and was able to adjust the dimension to ensure the pens were stable enough for the holder mounts and slots.
Also, my lap specialist advised me to increase the base area to completely include the stands/pipes that I used for the design in Fusion 360, and it was a valuable trick I hadn't noticed before so thanks to her always for her tips, this is not the first time I've done my own work/fabrication with her. Her advice is always making progress!
Besides, I was asked by one of my peers to help upload the G-code to the printer machine and how to start the printing process, so, I was glad to help, this increases my knowledge/experience in using the machine as well.
Also, I gave a tip to reduce the z-dimension of the holder model to one of my colleagues to adjust the printed model with the normal time and average grams consumed. Hence, I am always humbly ready to certainly respond to any request for help!
When I needed to change the color of the filament, I called for help from a lap specialist and when I finished the pattern, I had to to ask for help to remove the model from the machine bed and learned how to do it the next times.
If others are doing the same assignment, I guess they might want to avoid large dimensions, so it doesn't cost them too much time and grams to print. Also, they may need to check the simulation printing process after sliding the model with the Ultimaker Cura software to make sure everything is OK.
By identifying / learning and practicing some of the features / advanced parameters related to a 3D sketch on the Fusion 360 software such as Pipes, Loft that creates a transitional shape between two or more sketch profiles or planar faces and by getting more chances to deal with Ultimaker Cura program to set/adjust the settings/parameters required, I think that this will be more useful in designing and print out the portions for my graduation project.
Participating in the Molding & Casting Workshop was the most enthusiastic activity I did this week!
Just think with me now, if you want to make a 3D product (fully clear details) with high surface finish, least time and less consumable cost, what's the first thing you might think of?
Let me tell you... Molding and casting is the best option you can choose, yes!
You will need to use a milling machine instead of a 3D printer, as in the case of a 3D printer the surface finish will not satisfy you completely and if you made with high quality, then your cost will go up as well as the long time you spend! So, what do you think?
In this workshop I used a smooth material of Silicone rubber and a Wax mold and others such as resin, colors, glitters, Cup and sensitive scale to make my K black letter, yeah! This is what you can see in the next pic.
There are also other types of materials that can be used in a milling machine such as Chemical Wood.
If you love following this method of making 3D products, you may want to delve deeper into this documentation by our outstanding in-workshop instructor Ahmed Ibrahim | Week Seventeen (academany.org).You will find a sample of "Thor Hand" he did in Lap, he simply explained all the steps he went through including software, materials, machine etc. Have a fun trip!
