 * Day#4 – FREE ASSIGNMENT: 3D shapes from 2D cuts**


 * Reflections and Process - Week 1: Bree Galbraith**

As I mentioned numerous times this past week, this "Hacking" stuff is not what I am used to doing, and is quite new to me. I don't gravitate towards 3D work, or work that gets me messy in any way (at my advanced age, it's much harder to remove dirt from the crevices of my skin). That being said, I did learn a lot, and will be better able to direct people in the future when a project I am overseeing has some of the elements that we worked on this week ;-)

My first laser-cutting experience was quite positive, and I was able to create an "ASSASSINS" sign for my kids, which they display on their door (seen below), but my second attempt, and third and forth, left me very frustrated, as the machine was not able to cut through the cardboard efficiently, even after trying numerous settings. Live and learn. I do not have photos of this attempt, but have included an image of the PDF of the box/frame, which was to be a frame for pictures that could be hung from the wall.



The balloon covering/cutting and printing (thankfully not reassembling) was easier for me, and I was able to cover the balloon with cloth with little problem, and trace my pattern to create a vector in Illustrator. The best image is on Instagram, so if you want to follow me, please do: BREEGALBRAITH

Generative Computer Graphics. Another first. I was especially drawn to the images Jacob showed of the art that was in the process of falling to pieces, and spreading it's contents like a virus, and decided to emulate that in my Free Assignment, which I will explain later.

First, was the Processing. I wanted to (and was successful at) putting together a piece of code (is that right) from a few different places that would allow me to record the dragging of my mouse around and making rectangles, and than having a button that stopped the recording and made a PDF of the outcome.

After reading through the assignment, specifically, //"tweak the parameters, actively search for the glitches. use the artefacts of the machine and the workflow as part of your material. don't fight the system. hack it."// I decided to use the piece I had laser-cut in my 3D work. I liked the lines and how they were burnt into the page (paper cardstock, about 200lb) rather than cut right through. I took it home on the train and then used wire and pins to showcase the pattern, but in a more human manner. I then lit the piece on fire and attached it to a large canvas. It is very interesting, because it shows both a digital and analog way of burning... it also smells kinda funky.



Also - just a side note, I thought this link might be especially interesting since we are working on a 3D printer this week, its an article on FastCo called: [|Who Needs a 3-D Printer? This Dining Set Was Manufactured By Home Appliances]

Some //**food**// for thought.

 * Process in short, Edit, week1:**

A quick PDF on the results of two assignments:
 * drafting patterns
 * generative computer graphics – using the software Processing



My Processing / DXF design (see PDF) could unfortunately not be cut because the exported file was too heavy for the CAD software, also the closing hours of the office got close and run out of time. Though I wish to give it a try again next time possible.

Also I wish to continue experimenting w/ Processing, aiming for other type of designs, also ones that do not challenge the lasercutter and CAD software's abilities this much. Material-wise I wish to apply thin / flexible materials (e.g. thin flexible plastic, tracing paper and carbon paper), as these have the great potential to be activated by the force of nature (wind). I carry a vision of a design that combines several modalities (haptic and auditive) and owns minimalistic aesthetics. Fairly interested in transformations from 2D to 3D, when transformation happens naturally.

Back to nature... Here is the link to the documentary on 'Breaking the code - Mathematics in Nature'. Great watch! http://www.dr.dk/tv/se/knaek-koden/knaek-koden-former-2-3

**Process in short, Edit, week1, update:**

Today I gave the lasercutter another go – used the time for experiments w/ various materials, adjustments (speed and power) and getting the machine to engrave (as it apparently starts to behave strangely when it is forced to do any kind of engraving or dotted lines for that matter).

Tough I came up w/ some results and I definitely picked up some new knowledge that made me think further on errors and aesthetics. My results are not matching any final design on getting 2D to 3D (originally was aiming for an engrave that turns the material into 3D, as applying a sort of crumbling effect on thin materials, so they can fold into a crumbled shape, though my Processing experiments did turn into other directions, still learning) – these are parts of an experimental (learning) process, as I see them.

(Apologies for the lo-fi iphone pics, the machine could not get things in focus - will shoot proper ones.)



(see Processing screen shot of the same image in the PDF)

I also wanted to cut a fabric PCB (to make my own Arduino) and a small breakout board for an IC base, so I could stick any chip into it and sew it into a wearable project. Though it turned out that this needs further experiments - the tiny size of the cut design requires very fine adjustments regarding not burning out the small distances between the close lines, also the right speed and power needs to be adjusted for future. I got quite close the a 90% satisfactory though - apart from the odd 'liquidation' on front side. The fabric used is ShieldIt Super conductive fabric (from Less EMF) w/ adhesive on the back (so you can iron on).

...... alexSANDRO - EyeGlasses Holder_v2

I believe the pictures are self-explanatory. The process was: - hand drawing on paper (1:1 scale) - scan of the drawing - vectorization of the image in Illustrator - laser cut

I like this version of the eyeglasses holder and I want to laser cut it on acrylic ;-)

//Having used the lazr////cutr before, and being familiar with some laser cut joints, I choose to put my focus in creating the// //generative computer graphics through Processing. I've had a short introduction to Processing before, but back then I didn't get the time to really understand how the program works.// //I wanted to do a restricted and random generator that could process lines within a specific area, with simple commands to restart the program itself and to start/stop printing a pdf with vectors.//

//Through guesswork and tinkering nothing really happened, but after some time studying the reference list on processing.org I was convinced I could make it work.////The print command gave me so many problems that I had to ged advice from Jacob, because the program would only print one line of the ones that where showing on the screen. After a hint and some frustrating attempts I finally figured it out and started inputting the commands.//

• Mouseclick //generates a specific amount of lines in a random fashion withing a box parameter.// //• P// Starts recording, best done before using the mouseclick. • O //Stops recording.// //• R// Restarts the program.

Despite I missed the first week of the course I tried to do my best with the laser cutter. First two days I was experimenting with different materials considering the power and the speed. I also started with the ballon project, which showed me a new way of using the laser cutter and the fabric.



According to the available materials I chose an acrylic, a cardboard and a fabric from the hacker lab. First I cut out the bowl from the one ply cardboard. Despite good settings (power and speed) the cut-out was not so good because of the many curves in the design.



After the bowl I took a few days for the processing. Bree inspired me with her "wall picture", so I decided to process a design for a wall - I am living in Kolding only for three weeks now, so my walls are still white and empty :). Processing really inspired me, but because I am the beginner on this field I was a little limited. Taking into account that laser cutter can not print the complex designs I chose to print the design which is symmetric and not too complex.



Last but not least product I made is my own design for the pencil stand. First I made the prototype by hand and then I did another one with the cardboard. When I found the right measurements I cut-out the design from the three millimetres thick acrylic. I chose this material because it is reflective and also allows the light to pass through. Disadvantage of the chosen material is that it does not smell good during and after cutting :).

PROCESS WEEK 1 - PETER OTTO

SPHERICAL PATTERN CUTTING

After covering the ballon in fabric, which was harder then i looked, i tried to cut it out in spiral pattern, which worked out pretty good. media type="custom" key="23737272"

WORKING THE COMPUTER

In this processing sketch i wanted to create a way for people to grab a visual representation of the sounds around them and then export it. Unfortunately i wasn't able to figure out a way for processing to create a waveform from the microphone, so I ended up using some math to create a pseudo waveform.
