Printrbot is a successful fast growing 3D printer manufacturer. The company makes capable machines that are pushing down the prices of 3D printers. Its Printrbot Maker kit is only $349 and its Printrbot Simple metal goes for $599. At YouMagine we’re always interested in learning more about 3D printing and think that Printrbot’s affordable 3D printers can have a high impact on 3D printing. We’re also super proud that Printbot has released the design files for its systems on YouMagine, sharing them with the world through us. You can download the files for the Printrbot Simple Makers edition, Go 1212, the Printrbot Go 1408, the Printrbot Jr. 1402, the Printrbot Jr. 1307, the Printrbot LC 1308, Printrbot LC 1302, the Printrbot Plus 1303, Plus 1306, Plus 1311, Simple Makers Edition, Simple Makers Edition 1401, Printrbot Plus 1404 and the Printrbot Original from YouMagine. All are available, open source and on YouMagine! As well as the 3D printers Printrbot has a number of upgrades and accessories that you can make as well. We interviewed Printrbot founder Brook Drumm to learn more about the company and his plans.
Joris Peels: How did you first become involved with 3D printing?
Brook Drumm: I got a cupcake in January 2011 and became completely obsessed. I started building a Prusa Mendel in February and started a RepRap meetup in march. My PrintrBot designs immediately followed that march. I dove in head first from the beginning.
When did you first decide to make your own machine?
The first day I started building the cupcake with my kids, I knew there was a better way. Sourcing a complete open source kit was my first idea, but as good as the Prusa was, the RepRap community proved too diverse and random to believe that was the answer. I set out to do my own design, manufacturing and complete kit from the beginning. It was still early days and lots of room remained.
Why did you want to make a machine?
3d printers are complex. 3d printing is hard. I didn’t have all the answers, but narrowing the focus to value printers that were approachable has always been my goal. No one was hitting the $500 mark – what I could afford – so there was real potential there. A broad market was about to emerge.
Why do you share the design files of you 3D Printers?
I am a realist. I wasn’t an expert (yet) and I believe in giving credit where it is due. I stand on the shoulders of giants, and my values challenge me to remain humble. There was already significant momentum with RepRap so jumping on the bandwagon was a no-brainer. I wasn’t the first, so I wanted to continue to engage the community and be honest about my own strengths. I have always lives the open source software culture and I am by nature a disruptor. It was a good fit. The early RepRap crowd was a somewhat contentious lot, they didn’t like newcomers wanting to make a profit. Integrity proves itself over time, so I set out to give credit to RepRap while hoping to engage a community. I’ve loved every minute, but it has not been without a steep learning curve and mistakes.
Are you surprised at Printrbot’s success?
Constantly, but not because I didn’t believe I had nothing to offer. I’m surprised that no one else has challenged our price points. The wonderful spirit of the open source hardware movement never ceases to amaze. There is a wonderful thing happening in the world right now and it’s a dream to be a part of it.
Is open source & open hardware important in 3D Printing?
Open hardware has been essential to get the community involved and to jumpstart 3D printing. It is why my company exists and tons of other 3D printing companies. This movement has already changed the world. I think the open source movement is still having a big effect on the industry due to the number of people contributing to hardware designs and software. It does create a bit of noise, though… not all ideas or designs are equal, but the cream is rising to the top.
How come you can sell your machines for such low prices?
Less profit. Actually, that is a joke I crack at print shows when people ask why Printrbot is so much cheaper. Seriously, though, I still believe price is the first barrier to entry. Instead of getting the most money we can per printer, we wanted to build a long term, stable, scalable business. Now we have gotten really good at sourcing, creative solutions, making our own parts, designing for manufacturing, and ordering at scale. Thats great for the health of our company! We have really set out to gain market share and brand identity by selling a lot of printers. We are in the ballpark of 20,000 printers now – probably rounding up a little, but we will absolutely cross the 25000 mark in 2014.
Would you like to make them cheaper?
Yes. We WILL make them cheaper. We have a long list of ideas to continue to drive the price down. We will be able to hit a $299 price point on our Simple Maker’s Kit while improving a few things along the way. Our metal Simple and Plus will come down in price too. We just got a new CNC mill and small injection molder at Printrbot HQ and we are about to put them to work developing some of our cost-saving ideas.
What makes Printrbot different?
Great value is first. We have never made a perfect printer, but we have introduced more people to 3D printers under $500 than anyone. ever. Its because most people can’t afford to throw more than $500 at a bleeding edge, young, complicated technology. We like to keep things affordable and approachable.
Second, Printrbots have always been hack-able and we celebrate this! We are not in a box. I mean our printers don’t look like microwave ovens. Our current designs are very open so you can see how everything works and moves. Kids love to watch all the movement right out there in the open. Since we give away the files, people do all sorts of crazy mods and its wonderful to see. It is perhaps the easiest 3d printer to customize and change. Certainly, it is the easiest to expand the print volume – just buy longer bars and the Z axis grows. Right now all our bots are like that.
Size would be the third major thing. I am obsessed with minimalist. 3d printers are complicated, so keeping things simple and compact has always been my passion. Making small printers is a real challenge and squeezing out every last mm of space is exponentially harder. Small size isn’t the only goal, though. You have to strike a balance between size, ruggedness, usability and build volume. One benefit to small designs is that you can keep the part count low and materials cost less… leading to a cheaper overall price.
