Makerbot Has Now Cut 36% Of Staff In Last 6 Months

The CEO of Makerbot, [Jonathan Jaglom] announced this week a massive reorganization. Twenty percent of the staff will be laid off, management will be changed, an office will be closed, and perhaps most interestingly, the production of 4th generation of Makerbots will be outsourced to contract manufacturers.

This news comes just months after Makerbot announced its first 20% reduction in staff, and follows on the heels of a class action suit from investors. These are troubling times for Makerbot.

So Goes Makerbot, So Goes The Industry

In the last six months, Makerbot has closed all three of its retail locations in Manhattan, Boston, and Greenwich, CT. It has moved out of one of its office buildings in Industry City, Brooklyn as the company faces a class action suit from investors for possible securities violations. These are by any measure troubling times for anyone at Makerbot.

The 3D printing industry has been forced through the rollercoaster of the hype cycle in the last few years, and where Makerbot goes, media coverage and public perception of 3D printing goes with it. According to pundits, we are now deep in the doldrums of the trough of disillusionment. No one wants to make their own parts for their washing machine, it is said, and 3D printers are finicky devices with limited utility.

Despite these pundits’ projections, the 3D printing industry doubled in 2015. Multiple manufacturers of sub $5000 machines are going gangbusters, and seeing the biggest revenues in the history of their respective companies. By any measure except the one provided by Makerbot, we are still in an era of a vast proliferation of 3D printing.

Makerbot, for better or worse, is a bellweather, and public perception and media attention is highly dependant on the success of Makerbot. The Verge writes – incorrectly – “…The consumer 3D-printing market’s rise has slowed”, and Business Insider writes ‘consumers are beginning to lose interest.’ These are not statements backed up by facts or statistics or even hearsay; they are merely a reflection of the consumer’s disinterest in Makerbot and not of the 3D printing industry of the whole.

Unfortunately, we will not know the extent of how bad it is at Makerbot until Stratasys releases its 2015 financial report sometime in early March next year. Wohlers Report 2016, the definitive guide to the 3D printing industry, will be released sometime around May of next year. Keep one thing in mind: Makerbot did not build the 3D printing industry, and the public perception of Makerbot does not necessarily translate to the public perception of 3D printing.

Centrifuge Spins Samples Up To 400g

We were curious to see when someone would use a 3D printing pen for something other than art. It might not look very pretty, but [Techmeology] “drew” this centrifuge mount for a motor in order to spin some test tube samples.

It’s kind of hard to see in the picture, but the test tube holder “arms” are detachable, and when the motor spins up it opens like an umbrella. Pretty much all the parts are recycled, and the motor came from an old appliance, making the cost of this project negligible — a good use case for any remote location that might require custom parts or repairs.

As for actually fabricating functional items with the 3D printing pen, [Techmeology] offers some useful tips for drawing brackets on his site. For instance, wrap the parts for which you need mounting brackets in paper. This provides a barrier while drawing your design in molten plastic.

There are a few other tricks that can be performed by 3D printing pens, like using them to “weld” parts back together. If you don’t already have one you could just use a soldering iron for this purpose — or make your own 3D printing pen using LEGO and a hot glue gun.

VINYL CUTTER CNC

Turning Your CNC Into A Vinyl Cutter

This may seem like a no-brainer, but it’s actually pretty easy to modify your CNC machine to hold a vinyl cutter blade in order to do stencils or even cut out vinyl logos!

[Jouni] designed a holder for a standard Roland vinyl/sticker cutter blade (replacement with 5 blades is about $10 on eBay). It’s made to fit his specific CNC which uses a 65mm spindle, with a 49mm mounting ring — but the file could be easily modified to suit others.

Simply clamp your plastic or vinyl onto a flat piece of wood, and get stenciling! [Jouni’s] included his .STL file on his site in case anyone wants to try it out. While he’s designed it for 3D printing, you could probably CNC mill it as well — which would kinda make more sense…

3D Printed Plane Flies High

One of our avid readers, [Niklas Melton] loves RC planes. After getting into 3D printing, the next logical step was to start building is own planes… And now he’s done it!

He calls it the Air-Form 1 Micro RC plane, paying homage to the FormLabs resin printer he used. All of the parts except for the electronics were printed using a tough resin. It’s designed to take balsa wood wings into clips he designed into the parts. A 150mAh battery provides the power with a motor that exerts about 54g of thrust — not bad considering the entire thing only weighs 60g! Unfortunately he doesn’t have any video clips of it flying, though he assures us it does indeed fly — if you’re interested in building your own, he’s uploaded all the files to a page on Thingiverse.

As more advanced 3D printers come down in price, like the SLA technology, it becomes possible to design and 3D print even more complex parts. Some of the resins available have now some pretty amazing properties. One of our readers replaced a servo spline gear with one he printed — which works even better than the original!

Take Your Robots Tubing

When you think of a robot, you might think of one with wheels, tracks, or even legs. But today’s robots are as likely to have wings, props, or even some way to propel it through the water. If you are bored with quadcopters and want to build a water-going robot, you should check out Jalcboat, an open source robot/boat. Although the project is under development, the videos (see below) show that they’ve made a good bit of progress.

As you might expect, 3D printing is a key ingredient and the files are available on Thingiverse linked above. In addition, the robotic boat has a Raspberry Pi onboard to control brushless motors. The main web site is more of a discussion forum and some of it is in Spanish, so you might want to keep Google translate handy.

3D Printing Has Evolved Two Filament Standards

We’re far beyond the heyday of the RepRap project, and the Hackaday tip line isn’t seeing multiple Kickstarters for 3D printers every week. In a way, this is a bit of a loss. The rapid evolution of the low-cost 3D printer seen in the first half of this decade will never be matched, and from now on we’ll only see incremental improvements instead of the revolutionary steps taken by the first Prusa, the first Printrbot, and even the Makerbot Replicator.

This doesn’t mean everything is standardized. There’s still enough room for arguing over deltas versus Cartesians, beds moving on the Y axis versus moving along the Z, and a host of other details that make the current crop of printers so diverse. One of these small arguments is especially interesting: the diameter of the filament. Today, you can get any type of plastic you want, in any color, in two sizes: 1.75 and 3mm. If you think about it, it’s bizarre. Why on Earth would filament manufacturers, hot end fabricators, and even printer manufacturers decide to support two different varieties of the same consumable? The answer is a mix of a historical choice, engineering tradeoffs, and an absolutely arbitrary consequence of what 3D printers actually do.

Autodesk Open Sources Ember 3D Printer

If you’ve ever been interested in what goes on inside a (roughly) $6000 DLP stereolithography printer, you might want to check out the recent announcement from Autodesk that open sources their electronics and firmware for their Ember 3D printer. The package includes the design files and code for their controller (which is more or less a BeagleBone black with a USB hub, and more memory. It also has two AVR controllers for motor and light control.
