Indivisual Assignment

how i do my design

1- i draw a 2D rectangle with 60mm length and 30mm width

2- i extrude the rectangle by 8mm

3- i choose from google what i want to draw on the rectangle and download the images that i choose

4- i go to convertio website to convert the image from jpg to svg and then download the svg one

here is the website link convertio

5- i go to insert then to insert svg and put my design

6- i put my design above the board that i maked and manage the dimentions of it

7- i draw a circule on the board

8- i extrude all the design

download my design

to download my design just click

machine process

STEP1:First i Opened my file in SPR Player

STEP2:Here i selected Type of milling and i choose setting that give me a better surface finish

STEP3:Here i used the tool path for the machining and tool size used

STEP4:Here i did preview of the work and it was good

STEP5:Here i started the cutting and you can see the estimated finish time

the process

STEP1:First we created our mould using the machine we have in fablab by putting the plate inside the machine and the drill bit on the center of the plate

STEP2: After the moild was ready first thing we did was submerge the mould with water to make sure how much of liquid needed to fill the mould

STEP3:After we get arround 55.4g of water, we decided to fill the mould with 60g of silicon 30 of component A and 30 of B

STEP4:After that we mixed both of them

STEP5:Finally we poured the mix in the mould

STEP6: we mix the material that we want to make the design from it in a cup

not that the mixing ratio is 10g/6g resin/ardener for me i use 20/12 because i have two design

i add the green color to my mixture

STEP7:we poured the mix in the mould

final result

i didnt face any issue during this week
