Class action lawsuit against MakerBot dismissed

A class action lawsuit over the MakerBot debacle has been dismissed. The case centred on the fifth generation printer and now a Minnesota court has decided that the company did not wilfully mislead customers and investors after all.

There were obvious issues with the extruder in the MakerBot Replicator 2 and they have been well documented. The court inferred that the company had not behaved impeccably, but there was no evidence of serious malpractice. It will take some time for the dust to clear, though, and new CEO Jonathan Jaglom has a big job on his hands.

This company was the industry darling

MakerBot was the darling of the industry at one point and investors wanted a piece of the action. At its peak the New York-based company had more than 500 employees, having started with 60 in 2009. It was a totem for the industry.

There were bold predictions for world domination and everything looked good when Stratasys bought the company for $400 million in 2013. But MakerBot ran into quality control issues with the ‘Smart Extruder’ on its Replicator 2, the maker community turned on the company for profiting from open source work, its reputation suffered and last year the company laid off a number of its staff on two separate occasions.

This year parent company Stratasys outsourced the manufacturing and MakerBot is now a shadow of its former self.

Can MakerBot come back?

Of course it can come back, the question is if it will. The company is still going, Stratasys is one of the biggest names in 3D printing and there is always potential in such a young industry and an even younger business for the company to turn around.

A number of investors, though, felt they hadn’t been given the full facts and launched a class action lawsuit. There was even talk of Securities Fraud, as the investors claimed they had been oversold on the printer’s potential and indeed the state of the company’s health.

Stratasys did predict 25% growth in 2013, which was more than reasonable considering the growth in the industry and the growing public acceptance of 3D printing. It couldn’t account for the problems with the new printer, though, and the impact they would have on the company.

Non-actionable puffery?

This was dismissed out of hand by the judge. The court described those statements as ‘non-actionable puffery’. So the investors might feel aggrieved that the shares that were valued at $120 in September 2014 to $30 just a year later, but the courts have dealt with the case and it’s over.

The judge did not grant leave to appeal, so this case is done. What does that mean for MakerBot? Well it still faces a mountain to climb and the new CEO will have to work wonders to keep the company going, let alone going forward.

Other manufacturers have stolen a march, MakerBot’s market share has dropped and now it must convince a sceptical maker community of the company’s intentions and its viability. Good will is thin on the ground in the industry and that might be the biggest hurdle facing the company right now.

The only way to overcome this is to make outstanding products. We’ll be watching this one with interest and we’d like to see something more from a company that has been on the ropes for a while.

Think Geek Minecraft Pick Axe Foam Weapon Action Figure Accessory

You’re in a meeting. You need to escape. You need your freedom! Sadly, escaping a meeting isn’t the same as getting away from Zombies and Creepers. You can’t just tunnel your way out… Or maybe you could if you just had the Minecraft Foam Pickaxe!Replicating the stone pickaxe from Minecraft (data value 274 to be precise), the Minecraft Foam Pickaxe is an officially licensed Minecraft product. Okay, so a foam pickaxe is probably not going to bash through solid rock (or even soggy drywall for that matter), but with this baby in your hand you’ll feel like you can. And after all, isn’t it more important to have the confidence that you could smash things when you’re trapped in a room with crazy people?The Minecraft Foam Pickaxe is made from sturdy EVA foam, which means that unlike the stone pickaxe in the game, the Minecraft Foam Pickaxe will withstand far more than 132 uses. EVA makes the Minecraft Foam Pickaxe a sturdy tool, hefty yet with enough cushion that you’ll feel comfortable bashing a wide variety of materials. And of course, this is an officially licensed Minecraft product, which means you’re making Notch happy too.

Product Features

  • Based off of one of today’s hottest video games
  • Made of EVA foam
  • Combines the in-game 8-bit look with the heft of a real blunt force object

Build Your Own CNC Machine (Technology in Action)

Do you like to build things? Are you ever frustrated at having to compromise your designs to fit whatever parts happen to be available? Would you like to fabricate your own parts? Build Your Own CNC Machine is the book to get you started. CNC expert Patrick Hood-Daniel and best-selling author James Kelly team up to show you how to construct your very own CNC machine. Then they go on to show you how to use it, how to document your designs in computer-aided design (CAD) programs, and how to output your designs as specifications and tool paths that feed into the CNC machine, controlling it as it builds whatever parts your imagination can dream up.

Don’t be intimidated by abbreviations like CNC and terms like computer-aided design. Patrick and James have chosen a CNC-machine design that is simple to fabricate. You need only basic woodworking skills and a budget of perhaps $500 to $1,000 to spend on the wood, a router, and various other parts that you’ll need. With some patience and some follow-through, you’ll soon be up and running with a really fun machine that’ll unleash your creativity and turn your imagination into physical reality.

  • The authors go on to show you how to test your machine, including configuring the software.
  • Provides links for learning how to design and mill whatever you can dream up
  • The perfect parent/child project that is also suitable for scouting groups, clubs, school shop classes, and other organizations that benefit from projects that foster skills development and teamwork
  • No unusual tools needed beyond a circular saw and what you likely already have in your home toolbox
  • Teaches you to design and mill your very own wooden and aluminum parts, toys, gadgets—whatever you can dream up

What you’ll learn

  • Build your very own CNC machine
  • Learn about linear movement and motion transmission

Who this book is for

Build Your Own CNC Machine is the perfect book for hobbyists who like to build and create using wood and metal. It’s especially for those who have ever been foiled by lack of specific parts to help realize their creative designs. Build Your Own CNC Machine is also an excellent choice for organizations such as scouting and church groups, school shop classes, and so forth, as it provides an educational project of modest cost that all can work on together.
