6. Textil as scaffold#

This assigment was so experimental time, I have more than 713 pictures… My work is to experiment and try some differents tools. The output for the week is not a products with a demo but experimentations and researches. My final project is an output of this assigment with fabric, led, e-textile and crystal. I wrote some references during this assigment and some lesson from professional miling courses.

parameters for materials ranges

Tools	Clipper and plate	Hot glue	Fraises	Clippers	Pinces

Use	control Z axe	clip the material on the martyr	to sculpt the material	to change the tool	to secure the tool inside the rooter

Process :#

1. make the file export in STL (3D) DXF (2D)
2. put the material inside and secure it with glue
3. check the size
4. install your tool with the clippers (a good installation is a tool with a perfect sound)
5. open Vcarve pro (select the tool, parameter the material, register the passes)
6. open the file in shopbot
7. register the Z axe
8. register the x and Y axe
9. check out all tools
10. close the doors

Security check …

First milin test with a block of blue wax#

I need to make a flat surface because it’s a waste of the work space.

WAX Machine process#

I take a blue wax bloc from the trash, to moke my first test on this Shopbot.

Software process parameter and software :#

Link software with Shopbot: V carve To calculate the speed tools parameter from M.I.T. Neil Gershenfelf: Feed & speed calculator

Resume for Materials#

Tool : bol noize diameter 0.125 inches

Settings for wax	Settings for HDPE

depends to the provider of the tool, be carefull from the size inche/mm, and the settings of the tool at the lab we use american tools from providers like but in Toulouse I use to go there Mopa

aera to control during the process#

Speed from machine control	Axes control boxe

Selection the pocket and seting for each line / pocket#

My first job is to clear the surface of the blue wax and restart from a flat top.

Vcarve	Clear pocket selection offset conventional sens

select the depth total of the material	the depth of each passes and number of passes	then calculate

In the 3D view validate the sequence	play the path of the tool	Save the job I can choose different layer

At this point the parameter of the tool is needed, to see the process check the protocol bellow in the second part

Open the job in the shopbot control interface	Job settings	Then open the yellow box to register the 0 axes

CNC Process#

The material need to be on the martyr for this machine we use the hot glue.

Blue snow wax / shaving	Observations	Little “bavures”

Second pass	Snow / shaving	Surface

The size and the shape of the shaving, is very usefull to analyse because it said how the tool work. A wrong shaving, could need to change the speed and the parameters depends to your goals.

Wax can be remold…#

With a sustainable production I preconize to re-use the snow for a second projet.

Snow 1	Snow 2	Snow 3	Waste and Re-use

At the end of this process I had decided to change my material, and Romain take the block of blue wax for a test.

PEFT Mold#

Triangular shape from stl file in Vcarve.#

To make a good compression I have open the top and the botom of the mold and change the offset of the shape. The goal is to make an empty space part for the material depends to the thickness of the material (leather, resin, bioplastic…)

Tools for 3D files	Change the size of the height

Parameter from the calculator to the tool settings HDPE bal noise 0.125 inche	Parameter from the calculator to the tool settings 2
Take the parameter from the calculator	create a new tool in Vcarve with the dimensions of the tools

this part was dangerous because the resine goes away from the mold and then I have resine all around. But no bubble and good surface.

The process to grow up a cristal is simple. We found many tutorial and school process from teacher. But my interest is to manage the grow up process and control this part with fabrics, molds, electronics components. Also the key process could add quality of the cristal for it’s size, it’s color…

Key secrets#

• be sure that the bath temperature is at minimum 60 °C
• dissolve the basic ingredients once
• be calm and positive !
• make your own tools to manage the position of the cristal inside the solution

	Copper doesn’t go inside the classic trash! Different recipe tell us you need to filter the copper solution. In fact, if you have the good recipe with the good proportion and the good temperature , the whole powder is dissolve itself.
	Sometime you can have outside your petri dishe some big surprises like this big cristal !

The rule of clean space !#

Every day I have cleaned the grow solution :

1. put out the smaller cristals
2. add some clean solution

Beaker 1 before cleaning	Beaker 1 after cleaning	Beaker 2 before cleaning	Beaker 2 before cleaning

After 10 days of differents experimentations inside different recipe and bottles :#

I have selected the grown cristal with these rules : * a correct size more than 5 mm * a strong structure * a nice shape * a strong blue and deep color

January 2019 Session 2 Cooper Cristal#

First part interogations and different goals for my research :#

• [ ok ] serial of 7 small cristal inside a similar solution
• [ ok ] big cristal to mesure the size when it grow up more precisly
• [ ok ] 1 pattern cristal support with paper and copper tape
• [YES] see if the grown cristal after few week wainting always works ?
• [YES] is the solution it still working after 1 mounth ?
• [x] is it possible to grow up a copper cristal on gold chain directly ?
• [ - ] what is the material over the bottle ? Is it an air problem ?
• [ - ] copper treadh and copper solution, similar and difference between electrolyse ?

Copper treadh observation#

Test 0	Observations
	I have remplaced the thread by a copper thread. My observation was : the cristal grow twice faster than when it was on a classic coton tread.

Name test	goal
Test A B C D E F	Then, I take copper treadh and put on different cristal in order to make a little circuit around the cristal
Test I	I try to grow up a cristal on the gold chain directly
Test G H	I try to make a coild inside the crsital
Test X
Test J	I try to grow up with little chain cristal, and copper thread on a optic fiber directly

For thoses tests my protocol was :#

• Cristal weight < 1 gr at the 18.01.19
• Recipe : 800 gr Sulphate copper for 1000 mL 60 °C wather
• To 50mL to 100mL solution for each Bath
• When all the copper powder was disolve, I have wait the solution was colder and then I put the cristal seed inside.

From crystal to jewllery product :#

Scann the cristal to make an 3D image, and then make a support. In jewekkery they use Rhino to make the shape of each cristal.

transparence surface is not OK for 3D scanning process then add some powder	3D sense scan doesn’t work it’s too small
Try with the biggest cristal 9cm x 5cm	the process doesn’t work

LED + Cristal +++#

How to grow cristal around a LED to make cristal light or cristal light product ? I soldered a RED LED on resistor and put on a cristal seed. Then after few day the LED is ok.

Electronic cristal	test with battery to blink an RED LED before the bath

After this test I try to combine LED + circuit + fabric + cristal The result was very good, then you can see the process in my final project.
