ABSTRACT

The purpose of this experiment was to test the effect the material of 3D printing filaments has on the rotational speed of gears it prints. To carry out this experiment a gear bearing, downloaded from Thingiverse, was used to print with four different filaments, each containing different materials; Bronzefill made with bronze, LAYWOO-D3 with wood, LAYBRICK with stone, and Ninjaflex with a flexible plastic, TPE.

The alternative hypothesis stated that the bronzefill gear bearing would have the highest rotational speed. First the printing settings were adjusted using MatterControl 1.5. Then a calibration cube was printed in each filament, to test settings, before the gear bearing was printed. The axial turbine wheel file from Thingiverse was fitted with a ¼ inch hexagonal center, using Tinkercad, then printed. Next, each gear bearing was set on a table vice with a drill bit in the middle and the turbine wheel attached to the drill bit. Finally, an air compressor, set at 75 psi, was used to blow the turbine wheel, for 10 seconds.  A tachometer and reflective tape were used to measure the maximum rotations per minute. However, only the Bronzefill was able to spin with just the air and turbine wheel. These results proved the alternative hypothesis to be correct, the Bronzefill gear bearing had the highest rotational speed, because it was the only filament of the four that was able to function with this experiment.

 

HYPOTHESIS

Alternative:
If I compare the maximum rotations per minute for a 3D printed bearing in Bronzefill, Ninjaflex, Laywoo-D3, and Laybrick, then the Bronzefill will have the highest maximum rotations per minute, because it will have the smoothest print surface with the least amount of friction on the spinning gears.

Null:
If I compare the maximum rotations per minute for a 3D printed bearing in Bronzefill, Ninjaflex, Laywoo-D3, and Laybrick, then they will all have the same maximum rotations per minute.

ANALYSIS

Figure 2. The 3D printed axial turbine wheel (printed in PLA)
Figure 3. The 3D printed axial turbine wheel (printed in PLA)

All of the gear bearings printed well and were able to spin. However, when applied to the test, the Bronzefill gear bearing was the only bearing to spin with the turbine wheel and air compressor. Examining the results tells us that the Ninjaflex, Laybrick, and Laywoo-D3 gear bearings have a lot of friction between the gears. This may be caused by the materials used to make them. The flexible plastic in Ninjaflex may not have worked well because the bearing needed to be harder (similar to the Bronzefill bearing). The wood in the Laywoo-D3 bearing may not have worked because the wood is not as smooth as the bronze. The Laybrick bearing may not have worked because the material is too malleable, and the surface is too rough, causing friction.  The reason the Bronzefill bearing worked so well is because it had a much smoother spin than all the others and the material was metal, which works very well in gears.

 

CONCLUSION

The alternative hypothesis that the Bronzefill would have the highest maximum rotations per minute was accepted using a one way Anova test with a significance level .05.

Although Bronzefill worked the best, the other filaments did not yield results, so they cannot be compared to each other. The next step to improve this test would be to increase the size of the turbine wheel. This would make it easier for the given air pressure to spin the other gear bearings. Another way to improve the test would be to increase air pressure in the air compressor. This would put more pressure on the turbine wheel and increase its likelihood of spinning the other gear bearings. In conclusion, the Bronzefill gear bearing had the highest rotations per minute, but in order to rank the other filaments, the test must be improved.

3D Printing for Solving Baltimore’s Problems

Each year, DHF hosts our FabSLAM Challenge, where we invite teams of youth to use 3D printing and digital fabrication to create solutions to problems issued during the challenge. This year we had a great showing at our FabSLAM Finale Showcase with teams putting their fabrication skills and imagination to the test to solve problems they found in their city.

Our challenge theme this year was Cities to focus on very local problems youth might experience or be aware of, and to celebrate the fact that this year FabSLAM expanded to two new regions – Idaho State and Pittsburgh. Participating teams in each of those regions also responded to the same challenge. We will share more about those competitions in the coming weeks.

26348834564_4b7855dc71_z

This year, we had 10 teams from Maryland and DC competing who were eager to share their work at the showcase and meet the judges to share the work they’ve done over the last six weeks. Each team was asked to present their project, which should have used 3D printing and other digital fabrication techniques, as well as a website documenting their project and progress.

The finale showcase is always inspiring, energetic, and filled with anticipation as teams come together to share their projects, talk about the work they’ve done over the last six weeks, and anxiously await the results to see if their hard work pays off by placing in the competition. We had 7 teams from around the state competing in this cycle, eager to meet our judges and share all their project and all their supporting documentation to compete for a top placement.

Our First Place prize was awarded to Digital Oyster Foundation, a middle school team representing Digital Harbor Foundation. In response to the challenge, they worked to create a solution to the problem of a dwindling oyster population in the Chesapeake Bay. 3D Printed reef balls were the centerpiece of the oyster habitats they created, which also included an artificial wetland. They received kudos from the judges on the practical and possible nature of their design, recommending that they could get started right away with implementing this solution.

This is the very first time that any DHF team has placed in the competition and we were very proud of their effort.

For the second year in a row, Second Place was awarded to Innovation Nation, a Bryn Mawr School team. Their project, Home Grown, used 3D printing to help imagine what could be done to solve the problem of vacant and abandoned buildings in Baltimore. This team of young ladies took on the challenge of “converting abandoned homes into places of growth” by turning vacant row houses into greenhouses where community gardens could thrive. Innovation Nation also won the Fan Favorite award!

Third Place was awarded to another Bryn Mawr School team, Team Amasek, for their Storm Drain Filter. This project aimed to solve the problem of potentially toxic water runoff in Baltimore City storm drains thus contaminating the Chesapeake Bay. The product uses a simple design and a piece of charcoal for filtering the water as it enters the storm drain.

For the very first time in 4 years, we had elementary school teams participate in FabSLAM! In fact, we had three elementary school teams participate and they did a great job for their first time! One of those teams, FHP Team from Federal Hill Prep Elementary, took home an Honorable Mention from the judges for their ‘R’ Treat Machine aimed at helping to reduce the amount of cigarette butts and gum found on the streets in their neighborhood.

Laying My Spatula to Rest

 

No this post is not about anger issues in the kitchen. This post is about saying goodbye to a dear friend. My favorite spatula is soon to be replaced by a new product.

I am happy to be trying out the flexible build plates from PrintinZ. The plates are called Zebra Plates and they boast the ability to clip to your current build surface and then be easily removed to get your item off. The plate can be flexed in opposing directions allowing the print to pop off the surface. It sounded so good. I had to try it. I sent an email out and got a quick response from owner Wayne Hutmaker, who then sent me a plate for my Printrbot Simple.

IMG_0616

The plate lays over your existing bed. Then you use binder clips to hold it in place. You can see on the right side that I removed the handles from the clip so they do not hit when the bed moves.

My print came out nice and clean. This was a print for our upcoming post on our 3D Printed School Quilt.

Watch this video of one of our Northumberland senior, Hugh Hayner, get the print from the flexible plate:

DoodleFab at Northumberland Christian School

 

As an educator, I am always excited about the potential of crossing over subject material. 3D Printing has become the universal connector for me. How can I connect 3D printing with science? Math? Geography?

Lately my students have been enjoying turning their art into 3D objects. Thanks to DHF’s (Shawn’s) creation of DoodleFab, we are taking our 2D doodles, drawings, and sketches into the 3D environment. Two of my senior students love art (the art room their second home). When they approached me about turning their classroom doodles into 3D objects, I jumped at the opportunity.

Kyli had sketched a fox running through the forest on an index card with her pencil during class. (I am pretty sure she was still paying attention).

File_000

Then, her best friend Gabby wanted to do the same. She also used an index card to create a drawing of a deer skull adorned with a flower-like pattern. Gabby then created an a 3D replica of her drawing with Doodlefab.

FabSLAM Goes on Tour: Pittsburgh

In March we had the opportunity to provide our 3D Printing for Educators workshop as a kickoff for the first ever FabSLAM in Pittsburgh! Given that the 2016 FabSLAM theme is cities, it’s fitting that Digital Harbor Foundation has expanded FabSLAM beyond Baltimore. We were thrilled to help build the capacity of the coaches who will be forming and leading teams through the FabSLAM design and fabrication challenge.


Pittsburgh 3D for Ed - Educators 1

From the first moment that the eleven educators began their training, the room was buzzing with excitement and an eagerness to begin their FabSLAM process. The theme of the challenge wasn’t unveiled until the third day, and the educators were on the edge of their seats until the moment of the big reveal.

The educators were welcoming and passionate about the training that they were receiving and absorbed every aspect of the workshop from the 3D design challenges to the calibration of the 3D printers. Since they are going to be responsible for leading their youth cohorts through the entirety of the FabSLAM process, each attendee wanted to make sure to design and print as much as possible throughout the three day event.


Pittsburgh 3D for Ed - Educators 2
The educators were highly engaged and motivated as they navigated the interface of the design software and asked several questions while practicing some of the more advanced design tools and features that we presented. Their passion was evident as they made use of every spare minute to develop and practice their skills in order to empower and train youth. This especially came to the forefront when several educators chose to work through the lunch break, asking us questions as they anticipated potential issues that their youth may have while working on the design challenges.


Pittsburgh 3D for Ed - Adam 1
One of the designs that stood out the most for me was in response to the design challenge where they were tasked with creating an object that would clip onto the workshop tables. We didn’t provide the educators with the table dimensions before the project started. Instead, we passed a digital caliper around the room and every educator took turns measuring the height of the table’s lip. This process of precision measurement was new to several in the room, but they knew that since they would be asking their youth to be willing to step outside of their comfort zones during FabSLAM, it would be good for them to also experience some slight discomfort at attempting a new skill.

I’m pleased to report that everyone successfully completed the design challenge and designed items that would clip onto the table. True to the spirit of FabSLAM and 3D design, there was lots of iteration that needed to happen. The most important part is that the educators were excited to learn from the mistakes and pass their insights onto the youth they’d be working with!


Pittsburgh 3D for Ed - Printing 1
It was an amazing experience to be able to take the FabSLAM program on the road and to work with such an inspiring group of educators who clearly demonstrated their energy and passion for youth development.

A huge thank you to Remake Learning who worked to bring FabSLAM to Pittsburgh, and to the Carnegie Science Center Fab Lab for graciously hosting the workshop. I look forward to seeing the projects that the Pittsburgh FabSLAM teams create!

FabSLAM Goes to Idaho

A few weeks ago, Shawn, Jen, and I traveled to Boise, Idaho to kickoff FabSLAM as part of our national expansion of the program this year. We traveled to Boise to deliver our 3D Printing for Educators workshop to train the Coaches who will be leading teams for FabSLAM in Idaho.

IMG_9443

We had the opportunity to work with 22 educators from 15 different schools and organizations from all over the state, and had a wonderful time! These were some of the most enthusiastic educators we have worked with and extremely warm and welcoming.

Over the course of three days, participants learned all about how to use their 3D printers issued as part of the workshop, design their own objects to be printed, and search Thingiverse for inspiration and interest-generating prints to take back and share with their students. One of our favorite designs from the workshop was for one of the design challenges during the workshop – a mini documentation station for an iPhone made by C. Boothby.

IMG_0667

This was a great group of educators who really worked to bring their ideas to life and enjoyed themselves during the workshop. We were very excited to teach them all about FabSLAM and share everything we have learned to help them successfully bring this program to Idaho. We have never “taught” FabSLAM before to anyone, and it was very energizing and inspiring to work with such a receptive group of educators who are thrilled to launch this program with their youth.

A very special Thank You to Erica and Angela at the Idaho STEM Action Center who worked to bring FabSLAM to Idaho this year, and Jessica and Diana from Discovery Center Idaho for hosting our workshop all week! We fell in love with Boise and thoroughly enjoyed our time working with you and your educators!

DHF, Make Studio, & 3D Printing

One of the most exciting and engaging aspects of living and working in a city like Baltimore is having the opportunity to be involved in so many amazing and inspiring organizations. Over the past couple weeks, two organizations that I hold very close to my heart, both of whom inspire and enrich the communities that surround them through making, came together for a brief but awesome new collaboration.

Make Studio is a community-based art center and studio located in Hampden that provides programming, studio space, and exhibition opportunities to artists with disabilities. Artists involved in Make Studio make and use a wide range of materials and processes and exhibit their work throughout the Baltimore and Mid-Atlantic region. Make Studio is celebrating the aesthetics and concerns of artists commonly typed as “outsiders”, and bringing visibility to their observations and points-of-view, and essential asset to the vibrancy of our cultural sector.

Margie

DHF staff members Amber, Jonathan, and Darius joined me in a visit to Make Studio to introduce a Tinkercad and 3D printing as a new form of making that potentially could be a new and inspiring process for artists to experiment with. Several artists got their feet wet exploring 3D modeling and how it translates to the ideas and imagery they use in their studio practice.

Jerry Williams, also known by his alter-ego “Partyman” is a long time member of Make Studio and an avid painter and sculptor often working with found materials. He is inspired by WWE, the circus, as well as superheroes, and for a long time has been developing a series of Batmobile inspired sculptures from styrofoam and found materials. Tinkercad was an interesting new opportunity to see how these designs would translate onto the computer with 3D modeling and into a 3D print. “This was my first time using Tinkercad, I could see this as a special feature on the Batman DVDs. I really enjoyed doing the tutorials in Tinkercad. I like working with new technology, this might be something I use to create a logo for my future art organization Williams Art Enterprizes. I would be interested in making more models of the Batmobile!”

Aimee Eliason originally began her artistic pursuits in oil painting and has since explored a wide variety of mediums including painting sculpture, crocheting, digital art and photography.  She is fascinated by textures and can be inspired by something as subtle as the wrinkles on a piece of paper. Much of Aimee’s subject matter involves animals and/or anime, in Tinkercad she chose to develop (princess??) which not only turned out awesome, but also floored DHF staff members with how quickly she was able to pick up 3D modeling to create complex forms. “I loved Tinkercad and will use it again, there are so many exciting things to make!”

Aimee-Violinist-1 Aimee
Similarly, Dasha Kalumuck who joined Make Studio in 2015 picked up Tinkercad very quickly and was able to make some really fantastic characters. Dasha likes to take ideas and concepts and put her own spin on them in order to give the viewer a different perspective and as an artist is often using these skills to create character designs. Dasha uses many two-dimensional mediums including watercolor, acrylic, markers, sharpies, colored pencils, and collage but through the workshop was very inspired by 3D modeling as well. “I enjoyed Tinkercad a lot, it was super easy and fun! I am definitely doing this again, definitely! I was happy to just jump in and try something new. Seeing things I designed turn into real 3D things I can hold is amazing!”

Dasha Dasha-Heart
Louis Middleton often is found painting at Make Studio, but also has had a lot of experience working with computers. With the support of his family, Louis operates his own photo restoration business and has long enjoyed taking his own photographs, and now at Make Studio he is working to advance his computer skills, digitally manipulating photographs and original imagery, discovering new ways to express himself. Louis has many interests, but is often inspired by architecture and buildings he sees around Baltimore and that he finds online. After getting familiar working with Tinkercad, Louis tried out creating his own building based upon a painting he was already working on in the studio. “The experience was pretty good, I made a building from a painting that I have been working on and I had fun doing it”

Louis Louis-House
Margie Smeller knew a little bit about 3D printing before from her uncle who runs a makerspace in San Antonio however this was the first time she had the opportunity to try it out herself. Playing around in Tinkercad it was interesting to see how the colors and shapes drew similarities to the colors and patterns that can be found in her work. She was also able to create a 3D printed keychain for herself.

Gary Schmedes is a big fan of animation and is inspired by animation classics. In his work he primarily uses pen, ink, and watercolor and therefore was a little skeptical about any 3D modeling or computer based work. Despite this, he dove into Tinkercad, learning how to create different forms and ultimately produced this awesome print based on a character he has been working with. “Tinkercad was a good website, designing on it was neat. I designed a toad named Mr. Toad, although if I were to do this again I would have given him arms. It was really fun to create my own character in 3D, maybe for future projects I will use Tinkercad again.”

Bring Your Class on a DHF Field Trip

 

20122818473_1cf47279ef_k

Have you heard? DHF is now operating in the early morning hours too! Our 3D Printing Field Trips are off to a great start. So far this season, we have welcomed in groups of upper elementary students and a few middle school groups. The youth have all been awesome and have had so much fun!

During field trips, youth are introduced to a 3D design program and guided through how to use that program to create their own designs for printing. They use this tool to design their very own personalized keychains that they can take home with them.

Youth also learn about how 3D printers work and how they are being used in various industries such as fashion, architecture, and the medical field. This presentation is rich with information and real world examples to increase knowledge and interest in 3D printing for field trip participants.

FullSizeRender (1)

Field trips are a two-hour experience intended for groups no larger than 25. We prefer the youth to be fourth grade and above, but are open to exploring options for younger children. The youth should be comfortable using a computer and able to work somewhat independently.

Thanks to generous donors, we are able to offer a limited number of field trip opportunities free of charge to Baltimore-area public schools. If you are a Baltimore-area public educator interested in scheduling a field trip, act now because spots fill up quickly!

Don’t delay – schedule your field trip today!

 

 

Build Your Own 3D Scanning Computer

 

In this post, I’m going to tell you about the hardware parts needed to build an affordable 3D scanning computer that you can use with the Xbox Kinect.

This is a follow up blog post for people really dedicated to 3D scanning. If you are just starting out with 3D scanning, you may want to check out these resources first:

 

Software

Skanect is a piece of software that is available to Windows (32 and 64 bit), as well as Mac users. Skanect has a pro version that is $129, but also has a free version which allows us to create our 3D file, and export it. The free version is for non-commercial use only and limits the quality of your scans. Start with the free version and upgrade later if needed. Both versions are available here

Now, without further ado, onto the hardware!

  • Substitutes: It all depends on the amount of power your motherboard needs.

All in all, building your own 3D scanner computer is a fun task, and will allow for you and your youth to learn more about the inner workings of computers. This computer has been our go to for 3D scanning, and has allowed us to scan all of our staff members here at DHF. We were then able to take the scanned files, export them, edit them, and print them out on our own 3D printers. You DO NOT need to build your own computer to do 3D scanning, this is simply a slightly more advanced DIY project. This process is great for illustrating how digital fabrication works, from the ground up, as well as making personalized 3D figures.

 

3D Printing Landscapes

3DprintedLandscape2 (1)_opt

If you’re an geography enthusiast or looking for a cool project this might be the project for you!

Github user, JThatch, created a web application that generates landscapes into 3d models. The application is called Terrain2STL; it’s pretty easy to use!

If you’d like to try this, follow these simple steps:

  1. Open up Terrain2STL in a new tab; the creator uses Google Maps to search around for landscapes.
  2. Click and drag around the map to find a selected area or you can input coordinates.
    1. *Tip*  Rocky terrains works best.
      stlGenerator_opt
  3. Once, you find an area you like, click the ‘Center to View’ button to make the red box appear.
    3DLandscape2
  4. Then, you want to increase the box size by dragging the slider towards the right and then drag the to red box to where you want it.
    Terrain2STL1
  5. Once you’ve done that, you can almost ready to print. I’d increase the Base Height to 2 or 4.
  6. After that click ‘Create STL File’ and then click download.

 

There’s also a Moon2STL if you’d like to print pieces of the Moon!
