MakerBot And Ultimaker To Merge, Focus On Industry

Nine years ago, MakerBot was acquired by Stratasys in a deal worth slightly north of $600 million. At the time it was assumed that MakerBot’s line of relatively affordable desktop 3D printers would help Stratasys expand its reach into the hobbyist market, but in the end, the company all but disappeared from the hacker and maker scene. Not that many around these parts were sad to see them go — by abandoning the open source principles the company had been built on, MakerBot had already fallen out of the community’s favor by the time the buyout went through.

So today’s announcement that MakerBot and Ultimaker have agreed to merge into a new 3D printing company is a bit surprising, if for nothing else because it seemed MakerBot had transitioned into a so-called “zombie brand” some time ago. In a press conference this afternoon it was explained that the new company would actually be spun out of Stratasys, and though the American-Israeli manufacturer would still own a sizable chunk of the as of yet unnamed company, it would operate as its own independent entity.

MakerBot has been courting pro users for years.

In the press conference, MakerBot CEO Nadav Goshen and Ultimaker CEO Jürgen von Hollen explained that the plan was to maintain the company’s respective product lines, but at the same time, expand into what they referred to as an untapped “light industrial” market. By combining the technology and experience of their two companies, the merged entity would be uniquely positioned to deliver the high level of reliability and performance that customers would demand at what they estimated to be a $10,000 to $20,000 USD price point.

When MakerBot announced their new Method 3D printer would cost $6,500 back in 2018, it seemed clear they had their eyes on a different class of clientele. But now that the merged company is going to put their development efforts into machines with five-figure price tags, there’s no denying that the home-gamer market is officially in their rear-view mirror. That said, absolutely zero information was provided about the technology that would actually go into said printers, although given their combined commercial experience, it seems all but a given that these future machines will use some form of fused deposition modeling (FDM).

Now we’d hate to paint with too broad a brush, but we’re going to assume that the average Hackaday reader isn’t in the market for a 3D printer that costs as much as a decent used car. But there’s an excellent chance you’re interested in at least two properties that will fall under the umbrella of this new printing conglomerate: MakerBot’s Thingiverse, and Ultimaker’s Cura slicer. In the press conference it was made clear that everyone involved recognized both projects as vital outreach tools, and that part of the $62.4 million cash investment the new company is set to receive has been set aside specifically for their continued development and improvement.

We won’t beat around the bush — Thingiverse has been an embarrassment for years, even before they leaked the account information of a quarter million users because of their antiquated back-end. A modern 3D model repository run by a company the community doesn’t openly dislike has been on many a hacker’s wish list for some time now, but we’re not against seeing the service get turned around by a sudden influx of cash, either. We’d also be happy to see more funding go Cura’s way as well, so long as it’s not saddled with the kind of aggressive management that’s been giving Audacity users a headache. Here’s hoping the new company, whatever it ends up being called, doesn’t forget about the promises they’re making to the community — because we certainly won’t.

Thingiverse Data Leaked — Check Your Passwords

Every week seems to bring another set of high-profile data leaks, and this time it’s the turn of a service that should be of concern to many in our community. A database backup from the popular 3D model sharing website Thingiverse has leaked online, containing 228,000 email addresses, full names, addresses, and passwords stored as unsalted SHA-1 or bcrypt hashes. If you have an account with Thingiverse it is probably worth your while to head over to Have I Been Pwned to search on your email address, and just to be sure you should also change your password on the site. Our informal testing suggests that not all accounts appear to be contained in the leak, which appears to relate to comments left on the site.

Aside from the seriousness of a leak in itself, the choice of encryption should raise a few eyebrows. Both SHA-1 and bcrypt can be considered broken or at best vulnerable to attack here in 2021, so much so that for any website to have avoided migration to a stronger algorithm indicates a very poor attention to website security on the part of Thingiverse. We’d like to think that it would serve as a salutary warning to other website operators in our field, to review and upgrade their encryption, but we suspect readers will agree that this won’t be the last time we report on such a leak and nervously check our own login details.

MakerBot Targets Schools With Rebranded Printers

MakerBot was poised to be one of the greatest success stories of the open source hardware movement. Founded on the shared knowledge of the RepRap community, they created the first practical desktop 3D printer aimed at consumers over a decade ago. But today, after being bought out by Stratasys and abandoning their open source roots, the company is all but completely absent in the market they helped to create. Cheaper and better printers, some of which built on that same RepRap lineage, have completely taken over in the consumer space; forcing MakerBot to refocus their efforts on professional and educational customers.

This fundamental restructuring of the company is perhaps nowhere more evident than in the recent unveiling of “SKETCH Classroom”: an $1,800 package that includes lesson plans, a teacher certification program, several rolls of filament, and two of the company’s new SKETCH printers. It even includes access to MakerBot Cloud, a new online service that aims to help teachers juggle student’s print jobs between multiple SKETCH printers.

Of course, the biggest takeaway from this announcement for the average Hackaday reader is that MakerBot is releasing new hardware. Their last printer was clearly not designed (or priced) for makers, and even a current-generation Replicator costs more than the entire SKETCH Classroom package. On the surface, it might seem like this is a return to a more reasonable pricing model for MakeBot’s products; something that could even help them regain some of the market share they’ve lost over the years.

There’s only one problem, MakerBot didn’t actually make the SKETCH. This once industry-leading company has now come full-circle, and is using a rebranded printer as the keystone of their push into the educational market. Whether they were unable to build a printer cheap enough to appeal to schools or simply didn’t want to, the message is clear: if you can’t beat them, join them.

Prusa Launches Their Own 3D Model Repository

If you own a 3D printer, you’ve heard of Thingiverse. The MakerBot-operated site has been the de facto model repository for 3D printable models since the dawn of desktop 3D printing, but over the years it’s fallen into a state of disrepair. Dated and plagued with performance issues, many in the community have been wondering how long MakerBot is still going to pay to keep the lights on. Alternatives have popped up occasionally, but so far none of them have been able to amass a large enough userbase to offer any sort of real competition.

Sorting models by print time and material required.

But that might soon change. [Josef Průša] has announced a revamped community for owners of his 3D printers which includes a brand-new model repository. While clearly geared towards owners of Prusa FDM printers (support for the new SLA printer is coming at a later date), the repository is not exclusive to them. The immense popularity of Prusa’s products, plus the fact that the repository launched with a selection of models created by well known designers, might be enough to finally give Thingiverse a run for its money. Even if it just convinces MakerBot to make some improvements to their own service, it would be a win for the community.

The pessimists out there will say a Prusa-run model database is ultimately not far off from one where MakerBot is pulling the strings; and indeed, a model repository that wasn’t tied to a particular 3D printer manufacturer would be ideal. But given the passion for open development demonstrated by [Josef] and his eponymous company, we’re willing to bet that the site is never going to keep owners of other printers from joining in on the fun.

That being said, knowing that the users of your repository have the same printer (or a variant, at least) as those providing the designs does have its benefits. It allows for some neat tricks like being able to sort designs by their estimated print time, and even offers the ability to upload and download pre-sliced GCode files in place of traditional STLs. In fact, [Josef] boasts that this is the world’s only repository for ready-to-print GCode that you can just drop onto an SD card and print.

Regular Hackaday readers will know that we’ve been rather critical of the decisions made by MakerBot over the last few years, but to be fair we aren’t exactly alone in that respect. The community desperately needs a repository for printable models that’s in somebody else’s hands, and frankly we’re thrilled with the idea it could be [Josef Průša] leading the charge. His printers might not be perfect, and they certainly aren’t cheap, but they definitely don’t fail to impress. Here’s hoping this latest venture will be the same.

MakerBot Moves Away From Makers With New Printer

If you’ve been following the desktop 3D printing market for the last couple years, you’re probably aware of the major players right now. Chinese companies like Creality are dominating the entry level market with machines that are priced low enough to border on impulse buys, Prusa Research is iterating on their i3 design and bringing many exciting new features to the mid-range price point, and Ultimaker remains a solid choice for a high-end workhorse if you’ve got the cash. But one name that is conspicuously absent from a “Who’s Who” of 3D printing manufacturers is MakerBot; despite effectively creating the desktop 3D printing market, today they’ve largely slipped into obscurity.

So when a banner popped up on Thingiverse (MakerBot’s 3D print repository) advertising the imminent announcement of a new printer, there was a general feeling of surprise in the community. It had been assumed for some time that MakerBot was being maintained as a zombie company after being bought by industrial 3D printer manufacturer Stratasys in 2013; essentially using the name as a cheap way to maintain a foothold in the consumer 3D printer market. The idea that they would actually release a new consumer 3D printer in a market that’s already saturated with well-known, agile companies seemed difficult to believe.

But now that MakerBot has officially taken the wraps off a printer model they call Method, it all makes sense. Put simply, this isn’t a printer for us. With Method, MakerBot has officially stepped away from the maker community from which it got its name. While it could be argued that their later model Replicator printers were already edging out of the consumer market based on price alone, the Method makes the transition clear not only from its eye watering $6,500 USD price tag, but with its feature set and design.

That said, it’s still an interesting piece of equipment worth taking a closer look at. It borrows concepts from a number of other companies and printers while introducing a few legitimately compelling features of its own. While the Method might not be on any Hackaday reader’s holiday wish list, we can’t help but be intrigued about the machine’s future.

A Farewell To Printrbot

It’s with a heavy heart that we must report Printrbot has announced they are ceasing operations. Founded in 2011 after a wildly successful Kickstarter campaign, the company set out to make 3D printing cheaper and easier. Their first printer was an amalgamation of printed parts and wood that at the time offered an incredible deal; when the Makerbot CupCake was selling for $750 and took 20+ hours to assemble, the Printrbot kit would only run you $500 and could be built in under an hour.

Brook Drumm, Founder of Printrbot

Printrbot got their foot in the door early, but the competition wasn’t far behind. The dream of Star Trek style replicators fueled massive investment, and for a while it seemed like everyone was getting into the 3D printing game. Kit built machines gave way to turn-key printers, and the prices starting coming down. Printrbot’s products evolved as well, dropping wood in favor of folded steel and pioneering impressive features like automatic bed leveling. In 2014 they released the Printbot Simple Metal, which ultimately became their flagship product and in many ways represents the high water mark for the company.

Eventually, overseas manufacturers saw an opportunity and started flooding the market with 3D printers that were cheaper than what many would have believed possible only a few years earlier. Today you can go online and buy a perfectly serviceable starter printer for under $200, even less if you’re still willing to build it yourself. For an American company like Printrbot, competing at this price point was simply an impossibility.

Rather than give up, Brook decided to take things in a different direction. If he couldn’t compete with imported machines on price, he would start building high end printers. A new version of the Simple Metal was introduced in 2016 with premium features such as linear rails and cloud-based slicing, complete with a premium price. From that point on, most new Printrbot products would release at over $1,000; putting them more in line with “prosumer” machines from companies like Ultimaker. For hacker types who got their first taste of 3D printing thanks to a cheap wooden Printrbot kit, this was something of a bittersweet moment.

At the same time, Brook’s natural hacker spirit and love of the open source community lead to a number of interesting side projects that never quite got off the ground. Most recently, he’d been putting the finishing touches on the Printrbelt, a 3D printer with a conveyor belt in place of a traditional bed. Such a machine could finally bridge the gap between desktop 3D printing and true small scale production capability.

When we saw Brook at the East Coast RepRap Festival, he brought along a new machine that the more cynical observer might have taken as foreshadowing. The Printrbot Easy was going to be a modified and rebranded FlashForge Finder, a final acknowledgement that the only way to compete with the Chinese manufactured 3D printers was to sell one of your own.

It’s always sad to see a tech company go under, but seeing the end of Printrbot is especially hard. Built in America with locally sourced components and with a commitment to keeping their machines open source, there was a lot to love about the plucky little 3D printer company from Lincoln, California. Printrbot was the quintessential hacker success story, and we’re proud to say we’ve been in their corner from the start. Here’s to wishing Brook Drumm and the entire Printrbot team success in their future endeavors; we’ll be keeping an eye out.

Towards More Automated Printers

3D printers can be used in a manufacturing context. This might be surprising for anyone who has waited hours for their low-poly Pokemon print, but for low-volume plastic parts, you can actually run a manufacturing line off a few 3D printers. The problem with 3D printers is peeling the print off when it’s finished. If only there were a conveyor belt solution for a bed that wasn’t forgotten by MakerBot.

[Swaleh] may have a solution to the problem of un-automated 3D printers. He’s designing the WorkHorse 3D, a printer that uses a conveyor belt as a bed. When the print is finished, the conveyor belt rolls forward, depositing a printed part in a bin. It’s the solution to truly automated printing.

The use of conveyor belts to automate a batch of 3D prints isn’t a new idea. Way back in the Before Time, MakerBot released the Automated Build Platform, and used it in production to print off parts for Thing-O-Matics. This bit of Open Hardware was left by the wayside for some reason, and last year saw the invention of a new type of conveyor belt-based printer, The Infinite Build Volume Printer (for lack of a better name) from [Bill Steele]. This printer angles the print bed at 45 degrees, theoretically allowing for prints that are infinitely long. This idea was turned into the Printrbot Printrbelt, and the Blackbelt 3D printer was made public around the same time.

[Swaleh]’s printer is not of the infinite build volume variety. Instead of concentrating on creating long beams, most of the engineering work has gone into making a printer that’s designed to just push prints out. The conveyor belt bed is flat — and may unfortunately infringe on the MakerBot patents — but if you want a printer that’s designed to dump parts out like a very slow injection molding machine, this is the design you want.

The print queue application for this project is just a simple desktop app that serves as a buffer for G-code files. The app sends one G-code file off to the printer, rolls the bed forward, and queues up the next part. It’s simple, yes, but there aren’t too many things that do this now because there aren’t too many printers built to be factories. It’s impressive, and you can check out a few videos of this printer in action below.
