Week 1- Journal

First: The 3d printed Basket

I would use it as a retractable pot to grow plants and use wick irrigation or it could act as a holder for sweets so it has a dual usage. It is dynamic, flexible, and foldable that you can easily carry wherever you go.

Second: A Key Chain Holder

This is a more organizable tool that should be available at everyone's home so it matches my organizing character. I have added initials to indicate keys and we could easily differentiate each one.

First : Retractable 3d printed basket

I used Cura to slice the stl file, i changed the settings and exported a G-code file to the 3d printing Machine. The machine i used was (Prusa I3 Mk2) and a PLA material. It is easy to print, very inexpensive, and creates parts that can be used for a wide variety of applications. It is also one of the most environmentally friendly filaments on the market today.

Second : Key Chain Holder

I used LaserWorks v6 to change the settings of the speed and power of scanning or cutting layers. I used laser cutting machine (MORN MT3050D) to cut 3mm plywood because it is abundant local product and easy to be cut using the laser cutting machine. Also, it is cheap and deliver a high quality end products.

First : Retractable 3d printed basket

1) I used Thingiverse.com to download a stl file and imported it to ultimaker cura to change the settings of the file.

2) I adjusted the size through scaling the object and slize it to fit 1hr 30mins (i.e: does not exceed 90 minutes Quota).

3) I adjusted the infill to 20%, 0.2mm layer height, no support and no adhesion (i.e: no brim), Heat to 215 degrees.

4) save to disk > g.code file (1hr30mins-14gm-Nariman)

Second : Key Chain Holder

1) I used 3axis.com to download Dxf files and imported it to laserworksv6 software.

2) I transferred the origin to the Top Left corner of the sheet to save materials of the plywood.

3) I adjusted the size through rescaling

4) I have set the cut and scan layers by selecting colors and adjusted powers and speed of each layer.

• Red : Cut : Speed 30 :Power 65

• Blue : Scan : Speed 300: power 40

5) file > save as > RLD

First : Retractable 3d printed basket

1) I transfered my G-code to SD card and put it into the machine

2) I cleaned the 3d printer bed using alcohol and cut off extra part of the PLA.

3) turn it on and choose my G-code file it took 1hr 30 min and 14 gm.

Second : Key Chain Holder

1) I transferred my RLD file to the laser cutting maching computer and rechecked the power and speed with lab technician and click download to transfer it to the machine.

2) prepared the plywood sheet 3mm.

3) Choose the file and set the origin of the nosel.

4) close the machine for safety.

it took 7 m 14 secs.

1) I have asked amany and rechecked the data inputs before transfering the files to the machines.

2) I have checked the size through google of the Pins and Nails in order to cut their openings correctly https://ae01.alicdn.com/kf/HTB18SLdXpzsK1Rjy1Xbq6xOaFXat.jpg_.webp

3) I have checked the charter of the percentage of power needed to give the right shade of color of scanning through this link https://3axis.co/laser-engraving-material-test-template-dxf-file/075yxwmo/

4) I liked some of the files but it was crd extensions not DXF so i used an online converter to change the file from crd to DXF https://convertio.co/ (I.e: some has worked and other has missed data).

The quality of the laser cut 2d or 3d printed objects are manageable and should have precise adjustments to obtain a higher quality in a certain time needed.
