For years, the undisputed king of desktop 3D printing conferences has been the Midwest RepRap Festival (MRRF). Hosted in the tropical paradise that is Goshen, Indiana, MRRF has been running largely unopposed for the top spot since its inception. There are other conferences focused on the industrial and professional end of the 3D printing spectrum, and of course you’d find a Prusa or two popping up at more or less any hacker con; but MRRF is focused on exploring what the individual is capable of once they can manifest physical objects from molten plastic.
But on June 23rd, 2018, MRRF finally got some proper competition. As the name might indicate, the East Coast RepRap Festival (ERRF) is an event very much inspired by its Hoosier State predecessor. Held in Bel Air, Maryland, hackers on the right side of the United States for the first time had the opportunity to attended a true 3D printing festival without having to get on a plane. Not to say it was a neighborhood block party; people from all over the country, and indeed the globe, descended on the APG Federal Credit Union Arena for the two-day celebration of everything plastic.
This inaugural ERRF was, to put it mildly, a massive success. A couple of Hackaday Field Agents were in attendance, and we definitely came away impressed with the event considering it was the first attempt. We saw evidence that the RepRap dream of printable printers is still going strong, a gaggle of new printers and products that will be prying at your wallet this year, and an American-made hotend that challenges traditional wisdom. Of course we also saw a huge number of 3D printing fanatics who were eager to show off their latest creations.
We have no doubt that ERRF will return again next year, but until then, you’ll have to settle for the following collection of selected highlights from this year’s show.

While ostensibly the purpose of the recent East Coast RepRap Festival (ERRF) was to celebrate the 3D printing community and culture, it should come as no surprise that more than a few companies decided to use the event as an opportunity to publicly launch new products. Who can blame them? It’s not as if every day you have a captive audience of 3D printing aficionados; you might as well make the best of it.
Many creations were being shown off for the first time at ERRF, and we surely didn’t get a chance to see them all. There was simply too much going on at any given time to be sure no printed stone was left unturned. But the following printers, filaments, and accessories caught our attention long enough to warrant sharing with the good readers of Hackaday.
Keep in mind that much of this information is tentative at best, and things could easily change between now and when the products actually go on sale. These events serve as much as a sounding board for new products as they do a venue for advertising and selling them, so feedback received from show attendees may very well alter some of these products from what we saw at ERRF.

With few exceptions, it seemed like every 3D printer at the first inaugural East Coast RepRap Festival (ERRF) was using a hotend built by E3D. There’s nothing inherently wrong with that; E3D makes solid open source products, and they deserve all the success they can get. But that being said, competition drives innovation, so we’re particularly interested anytime we see a new hotend that isn’t just an E3D V6 clone.
The Mosquito from Slice Enginerring is definitely no E3D clone. In fact, it doesn’t look much like any 3D printer hotend you’ve ever seen before. Tiny and spindly, the look of the hotend certainly invokes its namesake. But despite its fragile appearance, this hotend can ramp up to a monstrous 500 C, making it effectively a bolt-on upgrade for your existing machine that will allow you to print in exotic materials such as PEEK.
We spent a little time talking with Slice Engineering co-founder [Dan], and while there’s probably not much risk it’s going to dethrone E3D as the RepRap community’s favorite hotend, it might be worth considering if you’re thinking of putting together a high-performance printer.

If you follow the desktop 3D printer market, it probably won’t surprise you to hear that nearly every 3D printer on display at the inaugural East Coast RepRap Festival (ERRF) was made in China. Even Printrbot CEO Brook Drumm had to admit that this was the year his company may finally bite the bullet and begin selling a branded and customized printer built overseas.
When you can get a decent (but let’s be clear, not great) 3D printer for $200 USD, it’s no surprise that American and European manufacturers are having a hard time staying competitive. But not everyone is seduced by low-cost printers. They know they could buy a decent printer for a couple hundred bucks, but for them that’s not the point. Some hackers are just as (if not more) interested in designing and building the machines than they are churning out little plastic boats with the finished product.
Luckily for us, these are also the type of folks who document their builds and make all their collected information and design files available for others under an open source license. Such builders exemplify the true spirit of the RepRap movement, and we’re happy to report that in a sea of imported printers, there were several interesting home built open source printers.
Whether you want to build your own copy of one of these machines, or simply get inspired by some of the ideas their creators had, these machines are physical proof that just because you can order a cheap 3D printer on eBay right now doesn’t mean you have to.

Last weekend was the inaugural East Coast RepRap Festival in beautiful Bel Air, Maryland. Like it’s related con, the Midwest RepRap Festival, ERRF is held in the middle of nowhere, surrounded by farms, and is filled with only people who want to be there. It is the anti-Maker Faire; only the people who have cool stuff to show off, awesome prints, and the latest technology come to these RepRap Fests. This was the first ERRF, and we’re looking forward to next year, where it will surely be bigger and better.
One of the stand-out presenters at ERRF didn’t have a big printer. It didn’t have normal stepper motors. There weren’t Benchies or Marvins or whatever the standard test print is these days. [James] is showing off tiny printers. Half-scale printers. What’s half the size of a NEMA 17 stepper motor? A NEMA 8, apparently, something that isn’t actually a NEMA spec, and the two companies that make NEMA 8s have different bolt hole patterns. This is fun.
If these printers look familiar, you’re right. A few years ago at the New York Maker Faire, we checked out these tiny little printers, and they do, surprisingly, print. There are a lot of tricks to make a half-size printer, but the most impressive by far is the tiny control board. This tiny little board is just 2.5 by 1.5 inches — much smaller than the standard RAMPS or RAMBO you’d expect on a DIY printer. On the board are five stepper drivers, support for two heaters, headers for OLEDs and Graphic LCDs, and a switching regulator. It’s a feat of microelectronics that’s impressive and necessary for a half-size printer.
Since we last saw these tiny printers, [James] has been hard at work expanding what is possible with tiny printers. The most impressive feat from this year’s ERRF was a color-mixing printer built around the same electronics as the tiny printers. The setup uses normal-size stepper motors (can’t blame him) and a diamond-style hotend to theoretically print in three colors. If you’ve ever wanted a tiny printer, this is how you do it, and I assure you, they’re very, very cute.
Are you around Philly, Baltimore, or DC, and looking for something fun to do this weekend? Great news, because Saturday sees the start of the first inaugural East Coast RepRap Festival in Bel Air, Maryland. Eh, we’ll grab some Bohs and boil up some crabs. It’ll be a great time.
Regular readers of Hackaday should have heard of MRRF, the Midwest RepRap Festival, and the greatest 3D printer convention on the planet. There’s a reason it’s so good: it’s not a trade show. It’s simply everyone in the business and a ton of cool people heading out to the middle of Indiana one weekend per year and simply dorking out. All the heavy hitters were at MRRF last year, from [Prusa], to E3D, to [Brook] of Printrbot. The 3D Printing YouTubers made it out, and the entire event was simply a thousand or so people who were the best at what they do just hanging out.
Want evidence a highly unorganized conference of 3D printing enthusiasts can be great? Here’s a working MakerBot Cupcake. Here’s full-color printing with cyan, magenta, yellow, black, and white filament. How about an infinite build volume printer? There are roundtables, demos, and talks. This is the state of 3D printing, and it inexplicably happens in the middle of nowhere every year.
This weekend, the East Coast RepRap Festival is launching. This is not an event organized by SeeMeCNC, the hosts of the Midwest RepRap Festival. This is an independent event, and we have no idea how it’s going to turn out. That said, the schedule of events looks great with 3D printed pinewood (douglasfirfill?) derbies, and of course, the event space will be filled with strange and exotic homebuilt printers. The big names will be there, and it looks like this may be the beginning of something great.
Hackaday is going to have some boots on the ground this weekend, and we’re going to be showing off the greatest and the best from ERRF. Tickets are still available, and it looks like this is shaping up to be a great weekend.

Right on, we’ve got some 3D printing cons coming up. The first is MRRF, the Midwest RepRap Festival. It’s in Goshen, Indiana, March 23-25th. It’s a hoot. Just check out all the coverage we’ve done from MRRF over the years. Go to MRRF.
We got news this was going to happen last year, and now we finally have dates and a location. The East Coast RepRap Fest is happening June 22-24th in Bel Air, Maryland. What’s the East Coast RepRap Fest? Nobody knows; this is the first time it’s happening, and it’s not being produced by SeeMeCNC, the guys behind MRRF. There’s going to be a 3D printed Pinewood Derby, though, so that’s cool.
జ్ఞా. What the hell, Apple?
Defcon’s going to China. The CFP is open, and we have dates: May 11-13th in Beijing. Among the things that may be said: “Hello Chinese customs official. What is the purpose for my visit? Why, I’m here for a hacker convention. I’m a hacker.”
Intel hit with lawsuits over security flaws. Reuters reports Intel shareholders and customers had filed 32 class action lawsuits against the company because of Spectre and Meltdown bugs. Are we surprised by this? No, but here’s what’s interesting: the patches for Spectre and Meltdown cause a noticeable and quantifiable slowdown on systems. Electricity costs money, and companies (server farms, etc) can therefore put a precise dollar amount on what the Spectre and Meltdown patches cost them. Two of the lawsuits allege Intel and its officers violated securities laws by making statements or products that were false. There’s also the issue of Intel CEO Brian Krzanich selling shares after he knew about Meltdown, but before the details were made public. Luckily for Krzanich, the rule of law does not apply to the wealthy.
What does the Apollo Guidance Computer look like? If you think it has a bunch of glowey numbers and buttons, you’re wrong; that’s the DSKY — the user I/O device. The real AGC is basically just two 19″ racks. Still, the DSKY is very cool and a while back, we posted something about a DIY DSKY. Sure, it’s just 7-segment LEDs, but whatever. Now this project is a Kickstarter campaign. Seventy bucks gives you the STLs for the 3D printed parts, BOM, and a PCB. $250 is the base for the barebones kit.
