3DDC 2016

On April 14th, I attended 3DDC, a 3D printing policy event hosted by Public Knowledge. I know this is a rather delayed post, but I think some of the topics brought up at the 3DDC event are worth discussing in this blog. There were panels of expert makers and 3D printing specialists, including some of our own from Techshop. The panels focused on 3D printing in regards to STEAM education, the environment, bridging the workforce skills gap, and the arts.

I attended the workforce gap and arts panels and was intrigued by some of the issues brought up by both the audience and panelists. For example, the workforce gap panel discussed the difficulties in teaching older makers how to use new technologies. As someone who grew up using a computer and learned to 3D model at a young age, I had never really thought about this. I always thought desktop 3D printers were relatively simple to use. Export the model as an STL, send it to the printer, make sure there is enough filament, hit the start button and *voila* a few hours later you have a print (ignoring the potential extruder clog- looking at you, Makerbot). But this process might not be as intuitive to someone who hasn’t used a computer from a young age or seen a 3D printer in action. While working at Techshop, I remember a lady calling in and asking if she could purchase ink and paper for our shop’s 3D printer. Of course it seemed funny at the time, but unless you’ve used a 3D printer, you probably wouldn’t know what the filament was made out of or how to load it into the printer. I can understand how learning to use this technology would be frustrating to an older audience. The panel discussed methods of teaching these new technologies to an older age group, from providing free classes at the library to holding workshops for retired veterans at Techshop. I believe you can “teach an old dog new tricks”, but it will take time and effort. Repetition and consistency is key in learning how to use machines and software; conduct tasks over and over until it is ingrained.

The first topic of conversation during the arts panel was using 3D scanning/printing to create replicas of famous pieces of art. The paradigm case: a 3D scan of Nefertiti’s bust. The bust is currently located in the Neues Museum in Berlin and is the subject of ownership conflict between Germany and Egypt. Two artists, Nikolai Nelles and Nora Al-Badri, snuck a 3D scanner into the museum and were able to gather enough data to create a detailed 3D replica of the bust, which they uploaded online and had this to say: “With the data leak as a part of this counter narrative we want to activate the artefact, to inspire a critical re-assessment of today’s conditions and to overcome the colonial notion of possession in Germany.” Though new information may have ousted the whole heist as a hoax, it brings up important issues with how we view the intersection of art and technology. What’s the difference between taking a picture at a museum versus a 3D scan? When does it become theft of cultural and artistic property? Does 3D printing an art piece make it a counterfeit? Does it matter who is overseeing the scanning and printing? Many museums are using the technology to preserve and document their collections. For example, look at the work the Smithsonian is conducting: http://www.3d.si.edu/. So what do you think? Is 3D scanning and printing detrimental or beneficial to how we see art?

The arts panel also brought in one of my favorite artists, Francis Bitonti. You might know him for his famous Dita Von Teese 3D printed dress (it’s killer). He is one of the most prominent and innovative artists using 3D printing and I’m excited to see what he has in store for us in the future. Here’s a picture of him during the panel, as well as his 3D printed dress. Overall, I had a great time at 3DDC and was left with many questions about the future of 3D printing.

 

Lasercutter Rotary Attachment: an Experiment

I recently started working at Tech Shop, a maker space in Arlington filled with 3d printers, woodshop, CNC routers, waterjets, and laser cutters. It’s a great place to work on your own projects or take classes to learn how to use the machinery. I work as a front desk assistant and therefore am able to take free classes- a pretty sweet gig if you ask me. About a month ago, I took the safety and basic use class for the rotary attachment for the laser cutters. In school, I used laser cutters to cut components of my models , yet I never knew a rotary attachment existed. Essentially, the attachment allows you to laser cut/etch on a curved surface. A very useful piece of equipment! Here is an image of my first project on it (Lord of the Rings nerdom):

After completing my first glass, I realized I could create some great gifts on the rotary. My friend Tori’s graduation is coming up and I thought it would be cool to make something for the occasion. Tori is a fantastic artist and appreciates handmade gifts; I decided it would be even cooler if I made something that incorporated her own art. I creeped through her facebook album of artwork until I found something I could easily etch on glass:

Beautiful design and only two-toned- perfect. First step, I needed to image trace and rasterize this bad boy in Illustrator. Super simple, took about a minute:

Afterwards, I had to resize the image to ensure it would fit on the glass I purchased. I measured the height of the glass and used that as the width of the image, then measured the circumference of the glass (used a caliper to measure the diameter then did the math) to use as the height of the image. I kept the opacity of the etch at 100% because I really wanted her design to stand out against the clear glass. I fit the glass on the rotary and let the laser do its thing. Took about 15 minutes to etch entirely, which I didn’t think was too bad. Overall, my handmade gift only took about 20 minutes. Safe to say, I will definitely be making more gifts on the rotary!

My first Vive Experience

I’ve been super excited for the release of the Vive ever since I saw this video of artist Alex Briskham creating 3D art with the Vive: https://www.youtube.com/watch?v=EYY-DZ14i9E. As an artist and architect, I am interested in how VR technology will play a role in the representation of 3D spaces. Currently, most architecture firms utilize renders, plans, and sections to convey both interior and exteriors of buildings. In undergrad, I would try to create animations and “walkthroughs” of 3D models I created. This is all well and good, but imagine literally walking in 3D digital representation of the space! VR allows users to really experience a space as they would in real life. That’s incredible.

My brother decided to purchase a Vive and was kind enough to lend it to my boyfriend Sasha and I for a few hours. We hooked it up to my rig (the Vive headset screen runs at a cool 90Hz refresh rate and a resolution of 3024×1680 and therefore needs some serious computing power) and set up the motion tracking cameras which detect the sensors in both the headset and controllers. When I first put it on, I was completely baffled at how realistic it felt. The visuals, along with the completely accurate controllers, really helped sell it as virtual reality. My favorite part was sitting atop Vesper mountain and playing with a robot dog whereas Sasha really enjoyed playing as an archer in the game Bowslinger (when you release the arrow, the controllers quiver as a bow would- crazy stuff).

Anyways, I thought I would share some images of mine and Sasha’s first experience with the Vive. Check ’em out!

 

Digital Documentation for Heritage Preservation: DC Symposium

I was fortunate enough to attend NCPTT’s Digital Documentation for Heritage Preservation Symposium yesterday, hosted by Mount Vernon. There were some pretty cool people there, including a group from the National Park Service (I got into a great conversation about diversity in parks with a young woman from NPS) and some architecture firms specializing in historic preservation. In my past, I worked at Monticello as an intern sorting through all of their old architecture documents (random side note: I once found a signed letter from Franklin Roosevelt while working), so I’m very interested in overlaps between technology and historical preservation.

There were two lectures that really stood out to me. Firstly, there was the HABS, HAER, HALS lecture by Richard O’Connor from NPS. Richard first discussed how HABS, which was developed 1933, set a precedent for documentation standards in preservation. He also discussed how HABS, HAER, HALS were the first heritage documentation programs to be digitized due to their value for K-12 education (apparently before this, you would have to go to the Library of Congress to view any of the documents). He then spoke on the pros and cons to laser scanning and digital documentation over manual documentation. He told us that some issues with laser scanning were that 1) people working with laser scanners had to have a clear understanding of the tech and specific training on how to use both the hardware and software and 2) there is a huge amount of data that comes from laser scanning a site, therefore an office must have high computing power to handle and sort the data. On the other side, laser scanning is extremely useful for fragile resources. Some sites won’t let preservationists conduct manual documentation because the site is easily damaged, whereas laser scanning is not disruptive and allows data capture in a timely manner. My office at the Department of State hopes to digitally preserve our overseas buildings, so conversations on laser scanning are particularly interesting to me.

The second lecture was led my Terry Kilby regarding drones being used to capture 3D data. Terry owns and runs his own drone company called Elevated Elements-he’s collected 3D data on multiple Baltimore sites using his drones. Currently, most drones use photogrammetry, which means taking photos in a grid pattern with 70-80% overlap to capture a site. He also discussed how some drones will utilize laser scanning capture in the future, which I thought was really cool. And just recently, sense and avoid drones were developed, meaning the drones will sense an obstruction in their flight path and move around it. Though I’ve never personally flown a drone, the technology is something I am interested in (specifically because 3D printing drone components is possible nowadays).

Overall, a great lecture series! I’m looking forward to seeing where this tech moves in the future.

3D Printing or bust

First blog post- woohoo! I thought it would be useful to make a blog about my interests, specifically 3D printing and tech. It will definitely be nice to have everything written down in one place (you know, rather than on sticky notes floating around my desk). Some background information on me: I’m a recent graduate of UVA’s School of Architecture, currently working in DC as an Architectural Designer for Jacobs Engineering and the State Department. My hobbies include 3D printing and digital modeling (obviously) as well as gaming, drawing, cross-stitching, backpacking and hiking, binge watching Battlestar Galactica on Netflix, among many other things.

I hope to achieve a couple of things from this blog. Firstly, I want to learn more about the maker movement. By collecting information regarding fabrication, digital modeling, 3D printing, tech, etc. and compiling it here, I’ll have a solid record of everything I’ve learned. Secondly, this blog will be the impetus to become more involved in digital fabrication. With a busy schedule, it’s hard to devote time to a hobby. However, the urge to write blog posts will hopefully keep me active in my 3d printing/tech pursuits.

My plans for this year are to purchase a 3D printer and to create printable objects. I also need to brush up on my grasshopper (a plugin for Rhinoceros software) skills to continue designing parametric models. Hopefully I’ll be able to achieve some of these goals and write about them along the way!
