RigidBot, LLC

Posted by Michael Lundwall (Creator)


As many of you know, the RigidBot 3D printer was originally a product of Invent-A-Part, Inc. In order to help the RigidBot reach its full potential it became necessary to split the RigidBot out of Invent-A-Part, Inc. Through great sacrifice, my family and I have put everything we have into the RigidBot, however it was not enough. I would like to officially announce that RigidBot LLC is its own separate and individual company. In this process new management will take over the majority of RigidBot, LLC operations, including a new investor.

You might wonder what that means for you as a customer. This has been a smooth transition over the last few months. RigidBot LLC has assumed all liabilities related to the RigidBot and will fulfill all of its existing obligations. Any pending refunds, warranty requests or otherwise will continue as before and will be fulfilled by RigidBot LLC. Invent-A-Part, Inc is no longer affiliated with the RigidBot or its products. 

Kickstarter and the launch of the RigidBot was a very challenging and exciting journey over the last two and a half years. We have a great product and a really incredible community. One could not be without the other. There have definitely been some bumps along the road and looking back there could have been changes made to make the process smoother. We did the best with what we had. The RigidBot that we delivered is far better than our original design. My wife and I, and the entire RigidBot team, would like to sincerely thank all of you for your support.

      I'm from Ukraine and still did not get RigidBot or refund.
      Moreover, on December I asked when I will be able to receive my RigidBot and on January I received answer that they have sold my machine to someone else.
      However they have said that they will have new machines in a few weeks and will provide me with another machine.
      BUT almost 3 months have passed since that time and there are no actions or answers. They even do not answer on my email where I ask about date when they will send me my RigidBot.

      I'm from Germany and until now I haven't ever reached the RigidBot. Payed 420$ and haven't seen a refund or the printer. Sorry guys, but this is not funny anymore. Please give us a RigidBot or refund our money! This should be fair for all backers who helped you with your printer!

      I am from Russia, and I still didn't get a refund. How long should I wait? It is not funny anymore.

      At this point I want a REFUND and will back some other person who will actually deliver!

      Interesting way to announce the transition. you say goodbye, nobody says hello.
      Who are the new/old faces to interface with?
      Are the new owners going to just kep selling spare parts or are they developing new generations?
      Will they stick to Open Source RepRap or go the Bre Pattis way?

      On my own personal note: I'm one of the 4 Israelis who paid a local Shenzen agent to pull the printers out of the warehouse and send them to us separately. Will the new LLC reimburse us the $90 for the shipment that never took place?

      For all those that didn't get the printer yet - I hope you get yours soon, it's a great product, I only wish Michael had not been burried in this by the product's own success. I know you'll enjoy it once you get it (and replace the PSU), because it's worth every penny, well, once it's in your hands.

      Hi Michael,
      it is not clear to me if you are still "inside" the new RigidBot LLC (with any different role) or you have lost at all your creature ?

      It was my first deal on kickstarter. I got only abs plastic. I wait a refund. How i can get it? Support ignore me.

    12. Sebastian Struß on

      I too want to know what does this mean for refunds?
      I was waiting years now for my printer to arrive and months for refund.
      The only thing i was told is that i had to wait for the printer to be sold.
      As many others i have spend over $1000 on this thing (with additions and second printer).
      All i want is clear information what will happen now.

      Michael- glad you get to close this chapter in life, I hope there's been no permanent damage done to your personal life and finances. I believe you had the best of intentions from the outset, and I'm happy with my RigidBot Big. Good luck in the future.

      Dear Mike, Thanks for your wonderful product with amazing value. It will inspire much more people than you imagine. Sorry to hear about the operation pains/growing that effected you and some. Need to also thank the wonderful support group on google plus that helped us with the support on getting the machine setup. Hope it was valuable in creating more great things in the future.

    17. Scott Kennedy on

      I hope that you and your family are still able to benefit from your sacrifice and hard work producing the RigidBot. I certainly appreciate it, and really enjoy mine.

      I'm sorry to hear you had to put so much of your personal money into this. I'm even more sorry to still see such vile attacks happen to you despite that. I hope this is a good solution and wish you and your family all the best for your future.

      I gave you several hundred dollars of my money and you raised some 1.1 million dollars! I have NEVER received my 3d printer years later...

      Will I receive the printer I paid for? Where did the 1.1 million dollars go?

    22. Øyvind Selbek on

      Interesting... development!

      Developments are good, in general - as there have been very few the recent years.

      Who is this RigidBot LLC? Who owns it and does it have a website and/or email address where it can be contacted?
