9. Textile Scaffold¶

This week was comprehensive we employed a lot of techniques that we leaned in the past weeks and explored more than one material or one tool to make designs

Crystallization¶

Crystallization in Nature

Crystallization is the physical transformation (phase transition) of a liquid, solution, or gas to a crystal, which is a solid with an ordered internal arrangement of molecules, ions, or atoms

CRYSTALLIZATION

ALUM¶

Alum is one of the best components to form Crystals I used Tull Fabric as a scaffold to grow my crystals on

Prepare this recipe by collecting the ingredients necessary, to be found in the list below:

Ingredients¶

    * 190gr Alum
    * 300ml Water

Tools¶

    * Pot
    * Coffee Filter
    * Jar
    * Threads or fabrics to grow crystals on
    * wooden stick
    * Foil Paper

The Process is simple but needs attention

First heat the water and start adding alum and stir
when the water boils and you still have some particals that means your solution is supersaturated nd you are ready to go
filter your solution
Add the object you want to grow crystals on
cover your jar with foil paper

NOTE: DO NOT MOVE THE JAR & MAKE SURE THE SCAFFOLD
 IS NOT TOUTCHING THE SIDES OR THE BOTTOM OF THE JAR

After 24-48 hours you will see this, it is magical

RESULTS¶

Alum Crystals Using Cabbage Dyebath¶

I repeated the process above but with cabbage dyebath instead of water and used Tull Fabric as a scaffold as well, I prepared the dyebath according to the recipe in week4 BioChromes

In this recipe I added a little bit more Alum to the dyebath because I felt it was not super supersaturated

Ingredients¶

    * 250gr Alum
    * 300ml Dyebath

RESULTS¶

SALT¶

Like the crystals we see in the Deadsea, Salt can form a very nice crystals this was my experiment using salt

Ingredients¶

    * 280gr Salt
    * 600ml Water

Tools¶

    * Pot
    * Coffee Filter
    * Jar
    * Threads or fabrics to grow crystals on
    * wooden stick
    * Foil Paper

RESULTS¶

COPPER SULPHATE¶

It is a blue component that dissolves in water, it is toxic so be carful when using it do not touch or smell, but it forms a very nice blue crystals, I used Acorns as a scaffold

Ingredients¶

    * 200gr Copper Sulphate
    * 300ml Water

Tools¶

    * Pot
    * Coffee Filter
    * Jar
    * Threads or fabrics to grow crystals on
    * wooden stick
    * Foil Paper
    * Mask & Cloves

RESULTS¶

To protect your crystals you can use transparent nail polish

Paper Making¶

I really liked what Ala'a Janbeh is doing with paper you should check her out

We recycled used papers to make new ones but in our way!!

Tools¶

    * 2 containers
    * used papers
    * wooden frames 2 for each size
    * sieve
    * cotton fabrics
    * blender
    * stapler
    * sponge
    * additives ( coffee, seeds, spices, dried plants,.... )

First you need to make your frame according to the size you want using wood, make them two
put sieve on one frame and tight it well using a stapler
shred your used papers
put in the blender with about half liter of water
use a larg container filled with water to cast you mixture in(the water should reach half of the second frame when put on top of each other )
pour you mixture into the frame then take it of the water

put you paper on a piece of cotton or wood to dry
use big sponge to take the water off you paper

you can use additives like coffee, safflower or any organic ingredient( put them in the blender for a better attachment )

RESULTS¶

COMPOSITES¶

A composite is two or more materials combined together to form a new material with new properties

Bio Silicon Cellulose Composite¶

I used the cabbage dyebath again, and modified it this time using vinegar and soda to dye cellulose

Ingredients¶

    * 48gr Gelatin
    * 24gr Glycerin
    * 240ml Water
    * 5-6 Cellulose Tissues
    * 100ml Cabbage dyebath
    * vinegar
    * Soda

Tools¶

    * Pot
    * Plastic Container
    * wooden stick
    * Spoon
    * Small cups for measuring

Make the Bio Resin following the recipe and process explained in week6 BioMaterials
Cast half of your Bio silicon in the container
add the cellulose tissues
cover them with a second cast
you can add pressure for a better result like covering them with another plastic sheet and use clamps for the pressure
leave to dry

RESULTS¶

I unmolded this after 2 days when I made sure it is completely dry

This material is flexible, stretchy, the spots with cellulose are rigid

Some extra work and expermentation¶

Bio Resin Cactus Fibers Composite¶

I was surprised by this... Those are the dried fibers inside the cactus and I am intending to make a side table out of them using bio resin

First I have to make a frame to cast in so I designed my frame using Illustrator saved my file as SVG and I am ready to laser cut

Fabrication file¶

frame

laser cutting¶

Laser settings¶

    * power: 100
    * speed: 0.20
    * material: palsitc/ Acrylic 5mm

Assembling¶

The pieces are cut and ready for the assembly I used A-B glue to glue them it is a glue with a hardener to dry faster, To make sure your pieces are accurately aligned I used a 90 degree ruler inside the frame while gluing

Now the frame is ready, I arranged the fibers in it and I am going to cook my bio resin

Cooking Bio Resin¶

Ingredients¶

    * 1.5kg Gelatin
    * 250gr Glycerin
    * 8L Water

Tools¶

    * A very lage Pot
    * wooden spoon
    * cups for measuring
    * scale

Still working on it .. :)

CNC Milling¶

CNC (Computer Numerical Control) machining is a subtractive manufacturing technology: parts are created by removing material from a solid block using a variety of cutting tools each tool is used for a certain application.

Things To Know¶

RBM¶

RBM is the (Revilotion Per Minute) and usually we keep safely at 14K depending on the material we are cutting and the tool we are using we refer to it as (n)

Cutting speed¶

cutting speed is (vn) and usually it is between 200-300 mm/minute

Cutting Diameter¶

cutting diameter is (dc) and it is the ..

Cutiing Tool¶

We have alot of cutting tool each tool has different applecation

Drill: has only one axis has no side cutting areas
End mill( falt\square - endmill ): is the most common used tool it cuts from its end and from the sides, it is used for making holes
Bullnose: it has a half circle end shap it is used for 3D machining, half circles making and finishing
Face mill: it is used for facing larg areas
V Tool: it is a very ssharp tool used for finishhing corners, hand writing and making orniments
Radice Tool: is used for making rounded corners (fillits)
T Cutter: used to make slots

Cutting direction¶

We have 3 different cutting directions for different applications

Up Cutting: is pushing the material upwards when cutting, uased for metals and plastics
Down Cutting: is pushing the matterial downwards when cutting, used for foam, wood, and MDF
Straight Cutting: is pushing the material behind and it cuts in one direction only, can be used for wood and MDF

Cutting technique¶

We have two cutting techniques to be used depening on the material and the tool we are using

Climb Milling: It is cutting from the thick area to the thin, it pushes the material towards the tool and it produces a very low friction and heat, used for soathing and finishing
Conventional Milling: It is cutting from the thin area to the thick, it pushes the material away from the tool and it produces more friction and heat, and have a bad finish comparing to the climb milling, but it advantage is that there will be no big prusser on the piece and it is used for cutting very thin walls

I learned alot about the CNC machine this week and I am going to use it next week
