Final Project Journal

the idea of this project is to make a device that can protect the filament from the moisture absorbed from the air by controlling the temperature and humidity needed for the used filament. This project solves the problem of damage to the filament. I am trying to implement this project for two main reasons:

The first is that: this project has not yet been implemented inside meker diploma.

The second: Fab Lab is in great need of such a project because it will save a large budget instead of wasting a large amount of filament.

I was inspired by this project because it was proposed to me by Eng Ahmed Ibrahim, in addition to that, I found a person in the Fab Lab who needed a filament and was unable to finish his work because the remaining film was damaged. I searched more from this moment to the project and I found it on amazon with different shapes also I found a Cad design to it on Thingiverse and grab cad.

Then I searched for videos that describe the idea of the project.

final project (fabacademy.org)

1-preparation:

first i start to design a 3D shape describe the final shape to inspire me the position of the joins which the design will need.

After design the 3D shape i found the shape is very huge to fabricate by using 3D printer so i decide to fabricate the project design using laser cuter machine ,so o start to design each part with t-slots to design the box.

2-design :-

Box parts:-

-Front part : I draw a rectangle the front part by dimension (130*300 mm) then i made an rectangle to put the on/of switch (15*20 mm) and made a t-slots to connect between front and the two sides and t-slot in the bottom to connect front with bottom then i draw rectangle with dimension (15*3) to join the parts of the box. after that i extrude the front part by (3mm) and import the LCD to make the rectangle in my design for it and determine the position of screw.

-Back part :I draw a rectangle the front part by dimension (130*300 mm) the I draw then I draw a circle with diameter (30mm) and draw a small circle inside it by diameter (3.5mm) then i choose circler pattern to make Ventilation holes for the components inside the box.

Finally I draw the T-slots to connect between front and the two sides and t-slot in the bottom to connect front with bottom and draw rectangle with dimension (15*3) to join the parts of the box.

After that I extrude this part 3mm.

-Right side: I draw a rectangle with dimension (130*120 mm) then I draw a T-slots to connect between side and the bottom and draw a two circle with diameter(3 mm) in the side at the center of the rectangle to join with the t-slots in front and the back part.

then i draw three rectangles in the last part from the side to connect power from this rectangles I draw one of them with dimension ( 10*40) then I mirror it then i draw between the two rectangle a big letter T with dimension (40*20).

in the high of the side i draw a two circle with diameter (3 mm) to connect with the t-slots in the heater holder parts.

Also I draw a 4 rectangles with dimension (3*15) inside the side part to connect with the parts.

then i extrude with 3mm.

-Left side: I draw a rectangle with dimension (130*120 mm) then I draw a T-slots to connect between side and the bottom and draw a two circle with diameter(3 mm) in the side at the center of the rectangle to join with the t-slots in front and the back part.

in the high of the side i draw a two circle with diameter (3 mm) to connect with the t-slots in the heater holder parts.

Also I draw a 4 rectangles with dimension (3*15) inside the side part to connect with the parts.

then i extrude with 3mm.

-Bottom part: i draw a rectangle with dimension (310*120 mm) then inside the rectangle i draw a 4 circle with diameter (3 mm) to join with T-slots by nail and draw rectangles with dimension (3*15) to join all parts of the box with the bottom.

then i extrude with 3mm.

-Top part: i draw a rectangle with dimension (310*120 mm) then i draw a rectangle with dimension(50*5) and select this rectangle and choose mirror to draw second one distance between them (55 mm) to put the filament inside these two rectangles .

Also I draw rectangles with dimension (3*15) to join all parts of the box with the top part.

then I draw a two rectangle with dimension (150*3) to put the acrylic in them.

then i extrude by 3 mm.

after that i insert a dc fan to put it inside the top ,so i should take the dimension then i draw a 4 circle with diameter (3 mm) to install the fan and draw a some circles with dimension (5 mm) to make the air throw inside the acrylic box.

acrylic parts:-

i draw a two lines with length (100 mm) and distance between them (300 mm) the i draw a circle with diameter (300 mm) and cut the half circle to formation this shape then i extend the shape by rectangle with dimension (150*3) to join with top part.

then i extrude by 3 mm.

After that i draw a rectangle with dimension (100*115) to connect between two acrylic part .

Then i draw a rectangle with dimension (500*115) to deform these part under high temperature to be the curve of the acrylic part.

Heater holder:-

i design a two rectangle one of them with dimension (299.5*45)and the other with dimension(299.5*35) to be heater holder and design inside these two rectangles T-slots to join with the box .

then i extrude it by 3mm.

3-Assembling :-

finally I joint all parts by choose the part then choose join to connect all parts together.

1-laser work:-

1. import DXF files to Laser Work.

2. move parts close to each other to the corner of the sheet to take the best benefit from the sheet .

3. adjust the speed and power to all of the parts to cut it.(speed 10,power 75) in MDF material and (speed 12, power70) in acrylic.

4. save file as .rld.

In my project there were 4 main components which need to be powered which are

Fan

Heater

LCD

Arduino Uno

All of them need 5V

so I used power supply 5v to power all of them and this power supply is 5A too and this ampere is enough for those components' supplying.

1- I started to put the LCD in it place in the front side and fixing the LCD by 4 screw .

2- put the switch in his place in the front side .

3- put the potentiometer in their place (circle 5mm) in the front side of the box.

4-fixed the fan by screws in the top part of the box.

5- heater was fixed above the heater holder which I have designed.

6- The DHT11 sensor places in the acrylic chamber and to connect its wires I made a hole with diameter 5 mm .
