As I mentioned, I love the art of origami and its also my hobby , So it is the first thing I searched for and found an origami press who make creases in the paper to make it easily folded to a butterfly . I'm very interested to see 3D printing machine make this model.
I also love reading and i hate bending paper of the books so i decided to make a bookmark.
Gold PLA material
I used PLA because it is one of the most environmentally-friendly 3D printing materials .
3mm plywood
I used 3mm plywood because it provides great value for money while also delivering a high-quality product.
Laser works
First step : I used 3axis.co to choose a suitable design and download it as dxf so Laser Work can read it .
Second step : Import dxf file to Laser Work software to change the setting to be suitable for cutting.
Third step : I adjusted the sizes and my instructor Amany helped me to determine the speed and power of all the design because I still couldn't know the difference between them.
1- I Changed the sizes to be 50*150mm because it was too big to be bookmark.
2- I give the cutting process red color (speed 15 & power 70 ).
3- I give the engraving process blue and black color ( speed 300 & power 25 ).
Last step : I saved the file as RLD.
Ultimaker cura
First step : I used thingiverse to choose a suitable design and download it as stl so ultimaker cura can read it.
Second step : Import stl file to ultimaker cura to change this setting to be suitable for the assignment requirements.
Third step : I adjusted the sizes because the original sizes will take 2 hours and 19 min and we have not exceed 90 min and my colleague Micheal helped me to scale down the model without losing the layers because this will affect my folding weapons so he suggested to scale down the X & Y axis without any change in the Z-axis and that works well.
1- I scale down the x-axis to be 124mm , y-axis 50mm and z-axis will be the same 2.25mm to make the time suitable .
2- I used 0.2 mm layer height.
3- I used 20% Infill.
4- No support and no adhesion.
Last step : I save the file as G-code ( writing the time , grams , material , color , infill and layer height) to be read by the machine.
1- I put my RLD file to the Laser Cutter computer.
2- click on Download and give name to the file.
3- choose the file in the machine.
4- Then i track the frame and Run the process.
The process takes 4m15sec.
My bookmarks
The process :
1- I transfer my G-code to SD card and put it into the machine.
2- I cleaned 3D printer bed using alcohol.
3- I turned on the 3D printer.
4- I cut off the extra part of the PLA.
5- choose my G-code file.
6- After the bed become pre-heated i watch the first layer to make sure that all things works well.
Finally : It tooks 1h28m and 14g.
Amany helped me a lot to prepare the file in laser works to be fabricated correctly and show me how to prepare the laser cutting and 3D printing before start the process.
Micheal helped me on how to scale down the model without losing in the layer height.
I got stuck when i slice the project and i realize that i need to change the setting but i don't know how can i make this without destroying the project function.
There are two options :
1- Make quality 0.3 mm but that will make the layer heights decrease into 8 or 7 and i think that will weak the sharpness of the edges.
2-scaling down but if we scale down while uniform scale check box allowed , it will decrease the layer heights too . so i have to scale down y-axis into 60 while uniform scaling allowed then know the number of x-axis then turn off the uniform scaling and keep z as it was before changing anything and write down x-axis and y-axis.
I learned that we should check the file in laserworks to make sure that there are no lines on top of each other because it affects the process of cutting because it burn the wood.
We learned how to make engraving by different powers and We learned different options to save time.
