2nd assignment by Melana Bogdan
Second week was very interesting for me, especially because of my first experience with the 3D printer. I also think that building it was an advantage for us, because now I can better understand how does it work. When we went to see the big printer at the faculty I also realised that despite of all disadvantages of the Ultimaker printer it is nice to have small printer that you can take anywhere you want.

At the end of the week I was building and printing my 3D models. I used free software like 123D Design and Blender. After I made the design I normally fixed it in Netfabb software and then I converted it to suitable format in Cura or Slic3r.



First printed 3D model I downloaded from the thingiverse.com because I just want to test how the printer behaves when printing complex models that require extra extruder for support materials. The sculpture was printed surprisingly well. Only disadvantage I found was that I could not remove all the support pillars.



After this I made an 3D Apple logo. I tried another way of building it - as a basis I imported image of the logo and made outlines. Than I just extruded them to the 3D model. Despite very thin edges the logo was printed very well. I also tried to print the chair but it was a fail because of too thin chair legs. In the end I printed my 3D cup. I chose this model because I want to make a water resistance test which was successful. During the printing I realised that I can use this temporary unfinished print like a box for my earrings so I stopped printing after good half an hour. You can see the result on the bellow images.

 * 3D Printing Week - Bree Galbraith**

3D printing. What can I say besides I am now confident that I could be considered and expert in the field... as long as someone is there to help me. I struggled with the 3D printing week for a few reasons, and eventually wrote about it, which you can (or don't have to bother) reading here below. That's what I do, I write about my process, ideas and concepts, and perhaps that's what I found was missing from this week, the discussion and the questioning and the sharing and recording of ideas.

Here goes:

“3D printing is not about hardware devices at all. In actuality it is about an ecosystem of innovation, opening the window to possibilities that have never been thought

of before.” //– Jennifer Lawton, president of Makerbot//

We are Designers, not Engineers.

Masters students studying Interaction Design, with a small window of opportunity to learn a great deal, should not focus on the inner-workings of technology (in this example, the construction of a 3D printer), as this opens up a possibly never-ending game of cat and mouse. In a world where technology changes, evolves, grows and dissolves so rapidly, the student’s focus should be on the innovative possibilities of technology, and should propel the technology forward by asking it to do things it can’t already do.

By focusing to intensely on how a machine is made, the student will begin to focus in too readily on the constraints, and learn to live and design within them. Changing the conversation towards what the systems around them are lacking, and what a tool, like a 3D printer can provide, allows the student to use technology as a means of looking at the big picture, where the people, services, culture and organizations are the driving force behind a products use (and misuse). An Interaction Designer should be able to merge the technology with social need, and to forecast changes in needs as the technology becomes more readily available and accessible. If the end-user will not be “hacking” together their own 3D printer, but instead purchasing one ready-made, attention must be paid to this experience.

If, by definition, an Interaction Designer is “focused on satisfying the needs and desires of the majority of people who will use the product” (Wikipedia), it should be expected that the Masters student in Interaction Design should engage in the same behavior as that “majority,” and use and abuse the technology in the same manner to learn what aspects of the design should be improved. We must also ask how 3D printing will change in a year’s time, or even two, when we have finished our degree. It is not just possible, but likely, that the technology will have evolved to the point where what is available is drastically different that what we have at present time, and may be unrecognizable, both inside and out. In other words, a designer shouldn’t focus on how things are made, but how they can be made better.

“The most stimulating possibility of this technology is unlimited customization.” //– Brad Hart, Forbes Magazine//

Designer as Maker.

In a world of waste, an additive process is a welcome change, and the designer should play an active role in pushing a technology that can cut-down the amount of product that enters the landfill and ecosystem. With the many forms of 3D printing becoming available for use, the Interaction Designer could play a role in making decisions about the environmental impact, such as the amount of hollow space needed in the design to make it amore effective means of production over others, such as milling. Designers who have had a hand in creating and maintaing a 3D machine may also have greater insight into the amount of actual waste, can conduct Life Cycle Analysis independently of a governing body, and find effective ways of managing the end-of-life disposal of the machines.

There are many social needs for 3D printing, one just has to tune into any news feed, //e// or otherwise, and see creative and innovative uses for the technology. Through 3D printing, “replacement parts” aren’t limited to nuts and bolts, but human tissue and the growing of hearts and lungs with integration of the transplant recipients own cells, ending the possibility of rejection. The ease at which parts are customized could mean a revolution in the world of artificial limbs as well, and the price point could make 3D printing more than just a step-ahead than the current precedent. If, as students, we are exposed to this technology, and gain a working understanding of the components, we enter the workforce with this knowledge, and use it to raise the standard of living for many around the world, and be involved in the conversation, not just be a bystander.

Designers are expected to work in cross-disciplinary environments, and a hands-on approach arms students with the necessary vocabulary to engage and be taken seriously with engineers and developers, and has the potential to see this technology grow into a more intuitive form. Interaction design students, who should be looking for ways to integrate human behavior into their work, can use the process of physically putting the machine together to familiarize themselves with how human error can play a role in the process, and ultimately derail a consumers attempt to create a much-needed component.

Finally, designers who work hand-in-hand with technology can also take advantage of the process, as they can play a more active role in the production of their designs, and make certain that the final design closely resembles their initial concept. They can also be in a position to tweak the parameters of their prototypes and have more time during the design process to test their results on their co-creators.

**//So now that we have that out of the way...//**

Here are my earliest attempts of printing a file from Thingeverse (sp?), which is what was recommended to me to do, since I had no prior knowledge of any 3D programs, and didn't need to "re-invent the wheel." I chose to print two Spoonriders, as I have 2 kids, and we all know what happens when you show up with only 1 Spoonrider! Needless to say, the first attempt was a learning experience because it didn't work for the following reasons:


 * 1) The base of one didn't stick
 * 2) I upped the speed to early in the process
 * 3) There wasn't enough support between the legs, where the dude rides the spoon

So I actually learned how to add support, but was left with only 1 Spoonrider! Utter madness ensued at home when I tried unsuccessfully to hide said Spoonrider from the children. They found him and they both laid claim to him. BUT! I made a compromise, and he is now the "medicine man" - he will ride the spoon when you are given medicine when you are sick, etc.



I then posed for MANY sessions of the Autodesk 123D Catch App, and the Kinnect body scan, and I am anxiously awaiting the images to be posted on the Wiki.



We also visited the 3D printer owned by the school, and the Design2Innovate Lab, which showed us how quickly the technology can change, as it is the size of a pop-machine, and is extremely costly, both to purchase and operate. It's one saving grace are the parts it prints, which are very 'professional' looking.



Being the amazing student/mother that I am, I then decided to further my learning, and try my hand at the printer the class put together, whcih I found to be much more straight forward, and intuitive! I tried to use Google Sketch-up to make some ice bergs for my son's diorama on the arctic, but I didn't know how to make them solid, even though they looked 3D, they had no base. Then I used another file from Thingaverse, and manipulated them so that one was big and one was small, and printed them at the same time. I was actually really impressed at how easy it was, and quite pleased with the result.



Thanks for looking! =**/ / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / /**=

PROCESS WEEK 2 - PETER OTTO --- TIME LAPSE OF THE ULTIMAKER PRINTING Because of some changes in the electronics, heatsinks on the stepper drivers, the cooling system on the Ultimaker hit the table it was standing on, so in order to fix this problem we printed a pair of feet.

Time lapse of feet being printed media type="custom" key="23888140"

In order to protect the electronics on the printhead, we printed a cover for it. media type="custom" key="23888170"

With the help of Bo, and his experiments with using a kinect for 3D scanning, we printed a statue of Jacob if you want to print your own jacob, here is the file [|JACOB]

 * 3D printing trials - Edit V :**

After assembling the Ultimaker and running the first trials prints – I took a look on the various CAD softwares that were introduced in the class. Some of them I used before, so I wanted to explore the potentials in the ones that I was not yet acquainted with: . Scanekt, for object and body scan – using the Kinect sensor; followed classmates doing scanning experiments, with quite satisfying results. · 123D Catch for IOS, using the iPad for scanning objects / body (as my iPhone 3gs is not supported, and I still wanted to give it a try, I went with this quite inappropriate device to shoot pictures with; hard to be precise with) I somehow like the idea of having the possibility of a realistic scan of an already existing object / human and placing it into a different context. Also these scanning experiments resulted in a series of errors that could open gates for e.g. new aesthetics. Though I could not get a final result that I could properly fix in a CAD software and clean it up for printing. Factors such as light conditions, precision of movement, angles, background texture and color, the ipad being able to focus, etc. were all decisive in the process, and still after a few scan trials I ended up with very unsatisfying results. · iGeo library for Processing – ran through the tutorials and have seen great potentials in iGeo, though then an idea hit me and I wanted to make it real. . This took me to using Google SketchUp and its function that enables its user to grab areas from Google Earth and then create a printable model out of these. So I grabbed a part of a mountain in the Austrian Alpines, which I connect to via memories. I got hooked on the concept of printing a small scale 3d model of a piece of memory – the tiny printed mountain resembles all of the experienced while being on site, and now I can just put it on the shelf and recollect these each time I take a look at it. Somehow incredible – or the time of 3D printed souvenirs has arrived...?

After I created a base for my terrain (not solid, creating an overhang), I started a printing process. This time I wanted to see what happens if I apply supporting material (that should bound to the base material), as I wanted to see the result of such a print. Though it was a trouble maker, as the base seemed to be too thin, and the filament did not stick quite to the bed.

I re-modelled my mountain, and I used different methods to make it so. Various obstacles appeared (troubling bounding edges, etc). I ended up with a quite satisfying print – very small scale though, which I wish to recreate in a larger version (20x20 cm). Also I did a trial with 5% inner fill (instead of 40%) and I changed the speed while printing to achieve errors in the structure. It still turned out to be quite OK though, and the upper layers are (almost) giving a solid surface.



//[Uploaded a PDF w/ the illustrative pictures, as Wiki makes the picture upload process too slow and it gets stuck from time to time.]//

//Future work// I would like to explore further and create a larger model with even less infill and //errors// (holes) in the top layer, so I can plant seeds in the model. So it gets green and soft. I am not aware of the filament that is used in the lab is //decomposable//, but it would be great to apply materials that are //eco friendly//.

Also another great experiment could be to apply //filaments out of various / and mixed materials//, such as e.g. sugar and a mix of PLA and conductive materials (graphite powder, steel powder, etc) and see if we could print conductive components for electronic circuits, even some sensors.

WEEK 2 / 3D PRINTING / BO FRØSIG

After building the printer(which was great fun!), I was lead through the process of making a profile for the printer by Martin. It certainly has some complexity to it, but I got the gist of it and with Martin looking over my shoulder we pieced together a really good profile for the ultimaker. Through that experience I got a fairly good understanding of the printer - never having done anything 3D print related before, that was a big help to understand the aspects of 3D printing. Having done some 3D molding and shaping in my semester in industrial design, scanning people with the Kinect and manipulating the meshes and cleaning them up before printing came quite easily. Already being familiar with Rhino, Blender and Cinema 4D, it was fun to merge that knowledge with new programs like Skanect, 123D Catch, KScan, RecunstructMe etc. It was fairly complex to get the software to work(lurch, drivers!) - but I had fun nonetheless.
