Be A Part of FabSlam 2015


We are excited to announce our 4th cycle of FabSlam this week! We are kicking off FabSlam 2015 today with the announcement of our theme and open registration for youth teams.

This cycle’s theme is KITCHEN!

For this challenge theme, teams should design and create a product that solves a problem someone could encounter in the kitchen.

We welcome teams of youth (with an adult coach) to register and join us to compete in this 3D printing competition. It doesn’t matter where you are geographically located, as long as you can attend the FabSlam Showcase at the end of the program.

What is FabSlam?

FabSlam is a multi-week, team-based, digital fabrication competition where youth learn and practice design, iteration, and rapid prototyping skills primarily focused on 3D Design and 3D Printing. A challenge theme is presented and each team works to develop a product that fits the theme and meets any accompanying requirements. Each team works with a Coach to help guide the team through the challenge and aid in documentation.

FabSlam culminates in a FabSlam Showcase where teams will present their their products to a panel of judges and a public audience for review and feedback.

Announcing the First Winners of the DHF Perpetual Innovation Fund Prize!

We are excited to announce the first winners of the DHF Perpetual Innovation Fund Prize, an initiative we  launched in January 2014 to provide a free 3D printer and training to educators who plan to start a 3D printing youth enterprise at their school. Each educator-led youth enterprise that receives funding commits to paying forward a portion of the profits from the 3D printed objects they sell, so that another youth enterprise can also benefit!

The winners include 9 entrepreneurial educators from the greater Baltimore region, Northumberland Pennsylvania as well as the entire San Rafael School District in California, which is committing to train multiple educators in 3D Printing technology:

  1. Andrew Pham, Benjamin Franklin High School (Baltimore, MD)
  2. Benjamin Johnson, Maree Garnett Farring Elementary/Middle School (Baltimore, MD)
  3. Brian Hoffman, Roland Park Elementary/Middle School (Baltimore MD)
  4. Cindy Marcoline, Windsor Hills Elementary/Middle School (Baltimore MD)
  5. Elisabeth Gambino, Academy of College and Career Exploration High School (Baltimore, MD)
  6. Ian Snyder, Northumberland Christian School (Northumberland, PA)
  7. Jason Peinert, Leith Walk Elementary/Middle School (Baltimore MD)
  8. Lynn Patterson, The Academies at Frederick Douglass High School (Baltimore, MD)
  9. Ryan Hoge, Patapsco High School and Center for the Arts (Dundalk, MD)
  10. The San Rafael School District (San Rafael, CA)

We received applications from across the country – from rural New York to California –  and these winners stood out as strong passionate applicants who are teaching 21st century job skills to students!

In addition, we are also very excited to announce that Scott Dellosso of Perryville Middle School, the first educator to receive funding from the Perpetual Innovation Fund in a pilot program, had already paid-forward the entirety of his Perpetual Innovation Fund Investment! We literally believe that 3D printers can pay for themselves, and are excited to see youth enterprises like Perryville already putting that belief into action!

The Perpetual Innovation Fund is made possible thanks to the R.W. Deutsch Foundation and their seed support.


Applications are now open for the second round of the Perpetual Innovation Fund Prize, which will be open until May 15, 2015.

How long does a roll of 3D printer filament last?

“How long does a roll of 3D printer filament last?” I get asked this question a lot and people are unsatisfied when you say “it depends.” So I decided to use the information we’ve been tracking on the models our youth are printing and get a better idea of how far a roll of filament will go.

Filament generally comes in 1kg rolls. This might seem counter intuitive since it’s a weight of filament and not a specific length of filament.

200 Keychains:
As part of our field trip experience, youth get to create a custom keychain that we print for them while they are here. The keychains are roughly 80mm x 20mm x 5mm and weigh on average, 5 grams (based on 108 keychains). One roll of filament will print approximately 200 keychains.

98 iPhone 5 Cases:
Who doesn’t love a good iphone case. It’s one of the first things our youth want to design and print. The iPhone 5 case is roughly 128mm x 62mm x 9.3mm and weighs 10.2 grams. One roll of filament should print approximately 98 phone cases.

103 Chess Pieces:
Chess pieces are also really popular as a first design. This DHF chess piece is roughly 19.5mm x 4.4mm x 73mm and weighs 9.7 grams. One roll of filament should print approximately 103 of these chess pieces.

358 Chocolate Molds:
I recently did some testing creating chocolate molds using our 3D printers. These molds measure about 96.7mm x 42mm x 10mm and weigh in at 2.79 grams. With these dimensions, we should be able to print 358 chocolate molds per roll of filament.

30 Nate Figures:
During our 3D for Educators workshop, we did some 3D scanning of the attendees and this was one of the results. Nate’s figure measures 55mm x 49mm x 52mm and weighs approximately 32.5 grams. This means, we could print 30 Nate figures to hide all over the Tech Center.

Maker Educator: 3D Printing Night Recap


Maker Educator: 3D Printing Night is our most recent offering from DHF’s Center of Excellence with the focus on bringing together educators to learn, create and, inspire each other.

The Maker Educator Meetup is designed to focus on three key components: review of new technology tools, hands-on learning techniques to apply the covered materials, and networking among educators to share ideas and experiences. We will meet quarterly to explore the latest technologies in the field and discuss practical applications to bring back to the classroom.


Our first meeting was held in December 2014 and the night was chock full of insightful tips shared by Shawn and Stephanie Grimes. We started the night with a quick presentation about 3D Scanning technology and reviewed different types of 3D Scanning tools to help users decide which tools worked best for them. Then, we jumped right into demonstrations on how to use the scanning tools and we loved seeing participants so eager to engage with the 3D printers and scanners. Participants not only walked away with new resources and connections, but some participants also had 3D printed busts made. To see other photos from the Meetup visit our Flickr page here: Maker Educator: 3D Night.

If you weren’t able to make it to our first meeting, but would like to learn more about the materials covered, you can read Shawn’s review of 3D Scanners here: 3D Scanners: A Quick Review.


Thank you to all those who attended our first gathering, we can’t wait to see how the group grows and develops! The next Maker Educator Meetup will be March 25, 2015 and you can signup here: Maker Educators: 3D Night.
