You can think of Qatayef as a sweet dumpling that is usually filled with nuts or cream. This dessert is usually served in Ramadan.
With Ramadan being right across the corner (NEXT WEEK), this is a perfect machine to build!
Our machine will be making the dough but we will have to fill it in manually (or maybe we can think of something while we're programming it to reduce the man labour required to eat this delicious dessert!)
The sketch of the machine drawn by Nadine. We have a fixed heated plate in the middle ,two motors carries Y axis and one motor moves in X axis and carries the extruder which also has a motor to move in Z axis to extrude the paste.
Design the X-axis.
I along with Nadine were supposed to design the x-axis. We both worked on separate designs, I created the first design using Acrylic with thickness of 6 mm and lasercut it.
I made a base which will fit the y-axis.
unfortunately it wasn't stable enough for the axis to move smoothly.
My lasercut design is seen below.
After both Nadine and my design using lasercut acrylic failed, I decided to design a 3D Printed part that would mount to the part that Isra'a created for the x-axis.
The part I designed had a bridge like structure and was self supporting as seen below.
This is the final result:
The next thing I worked on was how to put the heated bed on the aluminum frame without heating everything and causing the 3D Printed parts to melt!
I decided to lasercut a wooden piece that would fit into the frame and carry the heated bed. The piece was designed based on the side profile of the aluminum frame.
I tested a lot till I got a perfect fit. The piece is seen below.
We have MDF with 5 mm thickness, we glue two parts together to be stronger and hold the parts and it worked well :)
When we asssembled all the axes, we noticed that the x-axis wasn't all that stable, to fix that issue I designed a lasercut attachment that would attache to the 3D Printed bridges I made and hold them in place making the x-axis more stable and its movement far smoother.
The finished look of our machine
Future Improvements
- Chose other plate and another way to fix it with the frame.
- Find another way to design the attachment to make the bridge more stable.
- Try to control the Z-axis to so we can make a different 3D shape.
- Control the speed of motors movement and extrusion.
