If you’re a teacher making use of digital fabrication in your classroom, this may not surprise you. A relatively simple project can help you teach quite a number of topics. Check out Sallye Coyle’s blog post at 100kSchools.org, and you’ll see how making a lighted acrylic sign can help you instruct lessons about… CAD and CAM, the physics of optics, electricity and electronics, materials science, project management and documentation, and business topics such as quality control, cost analysis, market analysis, intellectual property….
We’re thrilled to announce that the Handibot® Smart Power Tool Developer Edition, first introduced by ShopBot Tools in a 2013 Kickstarter campaign, is now for sale at the Handibot.com online store.
The Handibot Smart Power Tool Developer Edition is a portable, digitally-controlled power tool for cutting, drilling, carving, and many other machining operations. You can cut woods, plastics, composite materials and soft metals with the power and precision of larger CNC tools.
David Bryan, Handibot’s Head of Development, said, “Last Fall we put 150 Kickstarter Handibots into the hands of makers, DIY’ers, educators, and small manufacturers who are at work on all kinds of projects. Now we’re hugely excited to get the tool out into the larger world.”
Ted Hall, President of ShopBot, noted, “Handibot is really two tools – at least conceptually: It’s a small CNC tool that you can put to work right now on construction jobsites or DIY projects, and it’s also a new kind of “Smart Tool” that in the near future you’ll be able to control with job-oriented apps.” Unlike ‘traditional’ CNC tools that require you to place your material on the tool, you easily bring the Handibot to wherever your material or work is located — the floor, ceiling, walls, etc.
Randy Johnson, ShopBot’s Director of Education, added, “Because of its size, portability, and affordable price ($2,795) the Handibot is useful in classroom settings such as vocational, technical education and STEM programs. It allows for hands-on ‘teaching by making’ — without an investment in larger CNC tools.”
Ready-to-make classroom projects can be found at 100kSchools.org. Here’s a father-and-children weekend design and cutting project where everyone enjoyed some hands-on learning (starring ShopBot’s Head of Production Support, Ryan Patterson, and his daughters…
The Handibot Developer Edition ships with a user-friendly CAD/CAM software suite for PCs or tablets running Windows. This software enables you to go from idea to making tangible objects using your Handibot with relative ease.
The Handibot Team is working on creating a suite of task-specific apps that will allow the tool to be run from multiple platforms and devices such as tablets and smartphones.

Designer and Oru Kayak founder Anton Willis grew up in rural Mendocino County, with easy access to rivers, lakes, and the ocean. In 2008, a move into a small San Francisco apartment forced his fiberglass kayak into storage. Inspired by an article on new advances in the art and science of origami, Willis sketched a few ideas for a folding kayak. Sketches turned into countless paper models, and over 20 full-scale prototypes built with the help of the full-size ShopBot CNC at TechShop SF. After user-testing on dozens of bays, lakes, rivers and oceans, Oru Kayaks are ready to explore the world. Read the full story and see video at our 100kGarages.com blog.

Hi, I’m Ryan Patterson, head of Production Support at ShopBot Tools. One important aspect of our company that I think sets us apart is the way we work with people to customize solutions for their production needs, from helping them to choose the right tools or tools, to assisting them with the configuration of tools to meet their changing needs. I’ll be blogging here on a semi-regular basis to share examples of this — starting with this entry that’s “close to home.” It’s the story of how we made some changes to our production method of Handibot Smart Tools here at ShopBot HQ.
While the Handibot was being designed, the production group had a general idea on how we would produce the product. The prototypes were cut on a PRS Alpha using a large universal vacuum system with a bleeder board. One Handibot was produced using a third sheet of 4×8 material. We thought we would scale this up to fill/nest a full 4×8 sheet of parts. We started cutting the first sheet and the estimated time to finish one sheet was a little over an hour. We were quickly able to see this would not work. A universal vacuum system uses a sheet of MDF as a spoil/bleeder. Over the time of cutting the MDF compressed and affected the depth of cuts. As we started making the final thru-cuts, the vacuum was not holding the parts in place. At this point we had two options, stay with the large format system (4×8 machine) with a gasket vacuum or move to a smaller cell based system (using the ShopBot Desktop machines).
We decided to use the smaller Desktop system with fixtures and a high pressure vacuum system.
With a cutting area of 24×18, we would need four different fixtures to have enough parts to produce one Handibot. Now we had to decide how many desktops we should use. One thought was to use one for each fixture and this is what we did. We later scaled back to using two Desktops, as we found that the cutting was not the bottleneck to producing the Handibots. This scalability was one reason for selecting the Desktop cell based option. As our efficiency down the line increases, we can quickly add another Desktop.
We are currently using two Desktops with four fixtures. The vacuum fixtures use a gasket around the inside of the cut with a high pressure low volume vacuum pump. For this type of vacuum system to work, no thru-cuts can be made inside of the gasketed area. The red lines pictured show the channel for the gasket.
The fixtures were created using VCarve Pro by importing all the parts for a Handibot, then manually moving and rotating the parts around to fit in a 24 x 18 inch cutting area. We used vector editing tools to offset geometry around the thru cuts to create the section for the vacuum. Once the geometry was created, it was offset .25 inches to create a .25 inch wide channel. This channel was cut .18 deep to fit the gasket of .25 x.25. We then added holes for mounting and indexing to the table. After the fixtures were cut we drilled a 1/4″ hole in the edge of the fixture for a 1/4 tube to be added to the gasketed area. Then we drilled a horizontal hole to connect with the edge drilled hole. We then inserted a 1/4″ tube to be connected to the vacuum pump.
Due to the fact we were using two machines with four fixtures, we needed a quick and easy way to index the fixture to be placed in the same spot every time. The index needed to be the same on both machines being used. The first step was to mount a sheet of aluminum 3/8 thick x 24 x 18. The aluminum was then surfaced to insure it to be flat. The next step was to drill and tap indexing holes into the table. We added matching thru holes drilled in to the fixtures. The tapped holes gives us a way to index the fixture and a way to hold the fixture to the table.

Behind the scenes, ShopBot Tools custom-designs and builds ProDesign’s CNC solutions to ensure smooth sailing.
If pictures are indeed worth about a thousand words each, let’s start this journey via a visual trip to Marseilles, where France’s ProDesign 3D customizes designs and builds boats, catamarans and yachts for dozens of leading boatbuilders, and also designs and builds boat-building kits for motorboats and sailboats. Here’s the ProDesign 3D racing team and their boat that they designed and built, entirely milled with their ShopBot CNC routers…
Here are some other finished boating projects from ProDesign 3D…
Johan Hallin, ProDesign’s Manager and Technical Sales Consultant, said, “I think what makes us stand out is, we are well-suited for any type of application and find a specific solution for our customers every time. One of our strengths is that we know well the needs of our customers and have the tools and expertise to realize their vision.”
Founded in 2001, ProDesign 3D has expertise in five main areas: engineering studies, 2D etching / prototyping, 3D volume machining, production of composite parts, and complete yachting maintenance and repair.
The company’s engineering experts will study your project from initial idea through the modeling, use 3D modeling software. They perform functions such as hull and stability studies, calculate structures and strength of materials. At this stage they provide conception, design, modeling, prototyping, and feasability studies.
They will often use 2D milling to begin a physical model of the parts…
ProDesign’s machining center is equipped with three custom-built ShopBot CNC routers so that they can precisely perform volume cutting of various materials such as PVC and polyurethane foams, plastics, woods and other non-metallic materials. Some examples of materials that they make are masts, V-booms, full booms, master hull pilotines, catamaran hulls and beams. Here are some samples of their machining process…

Molding for catamaran
Johan noted, “Back in 2001 we built our own table (5.2 ‘ x 19.7′) for a ShopBot CNC router, which they custom-designed for us with a 3-foot Z axis. The tall axis allows us to, among other tasks, to machine 3D foam inserts for catamarans; we also use a 1-foot Z for cutting panels. Sallye and Jamie from Shopbot traveled to France to help us with the assembly and to train our team in the initial operation of the ShopBot tool.”
“We worked 6 years with just this one ShopBot tool. As the demand for our custom services grew, we then bought a ShopBot PRS Alpha (6.5 ‘ x 13′ x 1.6 ‘), continuing to use the first tool for larger pieces. In 2013 we bought a third ShopBot, the PRS Alpha (5′ x 10′ x 1′).”
Johan said, “With our three ShopBot machines we can be very responsive to the demands of our customers, who are always pressed to have their parts quickly!” Learn more about ProDesign’s processes and services at www.prodesign3d.com

The Ninja Standing Desk is just like it sounds — it may well be the world’s first portable and affordable version of the permanently installed workstations you see around office and home businesses around the country.
The “Ninja” behind the Ninja Standing Desk is San Franciscan Dan McDonley, and his product has become a huge hit. It’s designed by Dan here in the U.S., prototyped here, and assembled from parts from here at home. Pretty cool. To help him bring this new product to market, Dan has been making good use of his local San Francisco TechShop with ShopBot and other tools, and he’s also reached out to 100kGarages fabbers as part of his vendor-sourcing. It’s an inspiring start-up manufacturing success — read the full story on the 100kGarages blog.
In the last months of 2013, as Santa’s helpers hurriedly made presents, the elves at Quirky’s headquarters in NYC were hard at work bringing new gift ideas to market. One of them is the Nimbus, a highly customizable 4-dial dashboard that tracks what’s important to you. According to Quirky’s site, you can “personalize each gauge using your mobile device to keep an array of info up-to-date and available at a glance. Nimbus can monitor your commute traffic, weather, email, calendar, social media networks, and more.”
Designed to be made with a plastic housing, Quirky’s product designers were hard at work readying a limited-edition, brushed aluminum Nimbus — and that’s where their ShopBot Buddy, with industrial spindle and 12″ Z-axis came into play.
But hang on, what is Quirky anyway? And how does it work?
Quirky has re-invented the process of bringing new products to market. Rather than taking the “old school” route of expensive market research, new product ideas are submitted by and ranked by the biggest market there is: the Crowd.
People are invited to submit their ideas, anything from half-baked notions on napkin drawings to fully baked ideas, to Quirky’s site for voting by the crowd. The most popular ideas are put into consideration for development into products for market. But participation doesn’t end here. People can get involved voting on the product’s colors, submitting names and more, and at each step of the way participation earns you points that turn into dollars when the product succeeds.
In this short video, Quirky’s Founder and CEO Ben Kaufman describes the lively interactive process of how a product gets chosen to bring to market:
Case-in-point: The Nimbus
That’s the Nimbus, below, balancing on top of the piggy bank.
The originator of the idea is Ryan Pendleton of Grand Rapids, Michigan. A self-proclaimed geek as well as photographer, gamer and journalist, Ryan’s initial inspiration for Nimbus was an app-enabled alarm clock, but it became so much more than that. Ryan saw an opportunity to have a bigger impact on peoples’ daily lives by incorporating diverse streams of information. Thus, Nimbus became a personal dashboard.
Ryan Pendleton, the guy with the idea for the Nimbus. So far he’s earned $35,946, and the Quirky Community (the crowd) has earned $43,005.
Prototyping the Nimbus
According to Quirky Product Designer Richard Ganas, Quirky’s ShopBot Buddy has played a critical role in the development process.
Richard Ganas, Quirky product designer
“We’ve had numerous 3D printers and other digital tools in our production studio for awhile, but our need to mill in aluminum, as well as to work with larger prototypes, has made the ShopBot Buddy invaluable,” says Ganas.
In addition to the plastic-housed version of the Nimbus, Quirky was working on preparing a limited-edition (a thousand or so) run of the Nimbus to be housed in brushed aluminum. Quirky had identified a local vendor to handle the limited run, but to test and refine the design in aluminum required milling work with the ShopBot.
Richard describes how Quirky employs its Shopbot:
“We currently use our ShopBot Buddy for milling in Renshape foam and aluminum. We use the Shopbot primarily for 3D milling, and because we want the ability to prototype larger objects, we chose to have a 12″ Z-axis on the tool. We have also used the Buddy to mill out molds for thermo-forming and casting.”
In the case of the Nimbus, the team first used Solidworks and 3D printing processes to play with different shapes for the product. Further along in the process the production team used the ShopBot and Renshape foam to help them determine the number and type of different tools they’ll need to ultimately produce the consumer product.
As they prepped the limited run in aluminum, the team made use of the ShopBot to help them make decisions regarding the final finish of the product, polished vs. brushed aluminum.
Milling aluminum with Shopbot Buddy
The unique value of the ShopBot to Quirky.
Rich Ganas explained, “Whenever we need to work with a larger product, the ShopBot is a great tool for us. For example, we’re working on a product in the shape of a helmet. For us to 3D-print a prototype would easily take 20 hours, whereas using the ShopBot and Renshape is much quicker. It enabled us to mill a few hundred helmets in foam and get them onto the heads of testers. And again, due to the size of the helmet, the Z-axis did the trick for us. Altogether, the Buddy is a fast, precise prototpying tool for us.”
Rich noted that he came to this tool with little background in CNC, but found he integrated the ShopBot into his process quite quickly. He noted that ShopBot’s forum has been very useful, and with any technical support issues, ShopBot’s team has been very responsive.

Eric Andracke is a High School Teacher at Mahomet-Seymour High School in Mahomet, Illinois. He’s currently in his eighth year of teaching at Mahomet-Seymour, twelfth year as an educator. Eric teaches classes in Construction, Manufacturing, and 3D Animation. He is a graduate of Illinois State University, with degrees in Technology Education and STEM Education. Simon Anderson, currently in his 3rd year at Mahomet-Seymour, teaches Introduction to Technology and Engineering Design.
So what’s this about STEM and football? Mr. Andracke wanted to share his school’s growing commitment to STEM education with the larger community — so a football game was a natural venue for it because the crowds were already there. He explained, “We took our new ShopBot Buddy out to the game to show off what it can do. We took several of the projects out there and had a little show and tell. It’s good for people in the community to see what is taking place inside of our classrooms and that was our main goal. The football plaque idea which I developed is a class project in my other manufacturing course. The students help design, market, and sell a useful product. We chose the football plaque idea this fall and showed it off at the game as well.”
Plaque designed, built and marketed by students in Mr. Andracke’s manufacturing technology program
In a recent interview via email, Eric talked about his experiences integrating ShopBot Tools into his teaching. Eric explained, “I have known about ShopBot Tools for several years. The department has tried to purchase one in the past but never been able to fully secure the funds. Last fall we were able to secure a grant to purchase a large machine. We were able to purchase a 4′x8′ Alpha with spindle with our grant funds. The funds also allowed us to travel to ShopBot’s headquarters in North Carolina for the training.”
As part of their curriculum, students recently worked to build a patio chair, the files for which are found on the 100kSchools.org website.
Patio Chair project and files available for download at 100kSchools.org
The students made some colorful modifications to the chair in order to personalize it for their High School…
SECURING THE FUNDS
Here’s an excerpt from Mr. Andracke’s grant application that helped secure the funds for the large ShopBot Tool:
“Our objective at Mahomet-Seymour High School is to develop, teach, and promote STEM (Science, Technology, Engineering, Math) education. Within the industrial technology program, we currently focus on problem solving, engineering design, and technology education. However, we are looking to expand our program to involve and inspire students through STEM education. The integration of the four major STEM aspects of knowledge can help prepare our students for both college and career. Our expanded curriculum also contributes to the national agenda of improving the abilities of America’s youth in science and math.
We plan to use digital fabrication (the continuum from digital design through digital production) as an avenue to explore STEM education at the high school level. To accomplish digital fabrication, we would like to purchase a computer numeric controlled mill called a ShopBot. With the help of this equipment, STEM education will succeed at Mahomet-Seymour High School. In most educational settings, science and math are taught independently from each other. However, STEM bridges that gap with hands-on activities, collaboration, and directive lessons. Our lessons will contain multiple learning objects that address state, national and common core learning standards. Students are also gaining a better understanding of the material since they are able to apply the knowledge to real-life activities.
An example STEM lesson is developed from the process of building a guitar. This lesson can focus on every aspect of STEM. Educational content covers mathematical calculations, science principles and equations, design, part engineering, and digital fabrication. This activity will generate students’ interest in areas of education with which they may not be familiar, furthering the development of STEM education. Engaging students into the content is often the first step into the learning process.”
If you’d like tips for writing your grant applications, you’ll find useful points at the 100kSchools.org resource section. The people at ShopBot Tools also make themselves available to review your grant application and make suggestions to help you boost your case.
BRINGING THE BUDDY ONBOARD
While he waited for the larger machine to arrive, Mr. Andracke became aware of the Autodesk 123D/ ShopBot promotion, Digital Fab Tools for Schools, that ran in early 2013. He applied funds from this promotion to purchase the Shopbot Buddy that had its special debut at the football game. Mr. Andracke said that his students “very quickly started making smaller parts and 3D signs. The students fell in love with the technology and abilities of the machine. Students constantly talk about what they want to make on the machines.”
We asked Mr. Andracke what was the experience like working with ShopBot. He answered, “Everyone is so easy to work with. From sales questions to technical support, they have been there to help. The reason we bought the Buddy was because of the Autodesk promotion, without that assistance we probably would not have been able to get that purchased. I had worked with some metal CNC tools before but no wood-type CNC tools. Our construction/manufacturing lab is home to our larger 4′x8′ machine and the Buddy is in another classroom that my department teacher Simon Anderson uses with his intro to technology students.”
We asked what projects the students were currently working on. “In my manufacturing class the students make an individual woodworking project. I have been working with kids over the last week to develop their projects in Aspire. Yesterday we cut out all of the parts for a student’s entertainment cabinet out of 3/4″ Oak ply. Our other big project right now is to get a guitar designed and built. We have been doing a ton of research on styles and electronics needed. We hope to get one of those done pretty soon, we have the part files ready to go.”
Finally we asked Mr. Andracke about his experience at the training sessions held at ShopBot:
Training at ShopBot Tools in Durham, North Carolina. Training is available in person or online.
“The training was very informative. I loved the fact that we could see where the machines are made and some of the inner workings of the company. I attended the training with the other tech teacher Simon. We both got a ton out of the training. There was a broad range of skill levels, but TJ did an amazing job with the content and delivery of material. Each day seemed to fly by, everyone was super friendly and easy to talk to. One suggestion I had was to offer an additional day for advanced ShopBot skills. More technical stuff related to cutting feeds/speeds, creating 3d with Aspire. TJ has made some great training videos which I have watched but we can always learn more!”
