Makerbot Patents twist the knife on open source 3D Printing roots, community responds.

Something is leaving a bad smell in the Open source community, could it be the recent Patents of big cheese Bre at Makerbot.

It's always very sad when you see a company or group turn their back on whatever community or project that helped make them successful.

Makerbot seem to be traveling down a darker and darker road as time goes on. I'm not sure if they felt invincible or that no one would notice but a recent patent frenzy by Makerbot has angered the open source 3D printing community. And we don't yet know what more is to come.

I prefer to use this blog to document work and talk about good things, so this is really a summary of past and recent events and links for you to find out more and make your own mind up about Makerbot's actions and community reaction to these disappointing and Machiavellian maneuvers.

And before we go on, I am not against Patents, they can be used for good to protect ideas and costly investments into research, that for some is a necessity to fuel sales and marketing of a product or invention. I don't think they are very fair and certainly not appropriate in many (most) cases, but they are not going away any time soon. For this trade off of hard work you can exploit an idea under a patent for a set period whilst also disclosing information about the invention and use.

Yes, RepRap and many open-source developments were built on expired patents. That's how it's supposed to work. A company gets 25 years to exploit it's patented invention, if after that time the market demand is still there and competitors can build a better mouse trap, then competition usually kick-starts another industry cycle and one could argue the original patented idea was not exploited well enough or the market was not satisfied with just one source of mouse trap.

What angers individuals is when ideas and developments that were in the public domain, very often with a specific open-source license are taken and patented by a company so others automatically now infringe. (or could be accused to infringe).

Patent trolling or this is abuse of the patent system is about as insulting as you can get to a community that encourages open innovation and sharing of open source developments.

Companies that can afford to mop-up open innovation into hundreds of patents, loosely based on ideas common in an industry or sector often have the power to legally threaten anyone that becomes a competitor. Using this abuse of the patent system can tie up smaller companies and stop new developments from even starting due to this sword of damocles handing over head.

Many things are just not worth patenting for companies or individuals, due to the cost and return possible along with the ability to be able to defend your patent if required. But if these seemingly insignificant ideas are patented by bigger companies who can afford the process, as a way to expand their patent portfolio, even if they were not 'invented' they take on another form of power.

Makerbot did 'invent' and patent an automated build platform, this was a commercial failure and proves the point not all ideas are worth patenting. Also the idea of an automatic build platform was openly discussed by various people when I first joined RepRap, long before the Makerbot patent, the difference here being that no one found it useful, practical or in any way essential, so the news Makerbot patented it was just not such of an issue.

Recent turbulent Thingiverse/Makerbot history - 
Back in September 2012 changes to the Thingiverse Terms of Service along with various concerns that Makerbot was moving away from it's RepRap and Opensource roots led to an Occupy Thingiverse campaign.

This was exactly what Thingiverse looked like on 20th September 2012 -


It was the Same day Thingiverse decided to promote and feature my 3-way colour mixing extruder. (And it had already been on Thingiverse and my Blog for 28+ days before this) - See image below 'Created by RichRap 28 days ago'


And the very next day after on the 21st September 2012 they filed a patent for build material switching.

Along with my 3-way multi-input material extruder above, I also posted, documented and shared my simple solution using lengths of different materials to produce multi-coloured objects - that was back in June2011.

Makerbot want to patent various things to do with multicolour and multi-matrial mixing, much of which has been done and documented in the open source community (Even directly at Bath University - UK as early as Feb 2012 and mentioned on the RepRap Blog June 2012 - Myles corbett report) This, over the last few years and is a very active area of open-source 3D printer development for myself and many others.

Plenty of other patent applications are also being submitted, we can only see the ones that have been published, so who knows what other things are in the pipeline...

Many of the recent Makerbot patent applications can be seen and read on this site here - You can search for Makerbot, or click on this search link here 

Title - BUILD MATERIAL SWITCHING
Abstract - A three-dimensional printer uses transitional lengths of build material to facilitate changes from one color to another during a fabrication process, and more generally to achieve multi-color objects corresponding to color patterns on the surface of a three-dimensional model. The transitional lengths of build material may be positioned inside a fabricated object, such as for infill, or outside the fabricated object where undesirable aesthetic properties of the transitional lengths will not impact the desired distribution of colors on the surface of the fabricated object.

Title - COLOR SWITCHING FOR THREE-DIMENSIONAL PRINTING
Abstract - By reversing the direction of a first build material fed into an extruder, the first build material can be wholly or partially evacuated from the extruder before a second material is introduced. This approach mitigates transition artifacts and permits faster, more complete changes from one build material to another.

A founders Perspective - 
A day later after the 2012 Occupy Thingiverse - Zach Hoeken posted his view of the changes he observed to Makerbot here-


Makerbot Patent Rage Coverage - 

OpenbeamUSA has one of the best overviews of recent Makerbot patent troubles, it's well worth a read, and I don't need to repeat things here - Stay classy, Makerbot

This also contains the details of how you can file a prior art application to help block a patent that is based on someone else's work or in the public domain.

TechDirt - MakerBot Files For Patent On A Design Derived From Work By Its Community


Please discuss, share and the tag #TakerBot seems to be being used by people -

If you are now looking for a place to share, YouMagine is a very good starting point.

GitHub is also an option, and a simple method to export all your things from Thingiverse uses a simple Python script by Carlos GarcĂ­a Saura - Look Here for info.

Repables is also looking good for content sharing, and is being further developed right now.

Ultimately work like the Thing Tracker Network, by Gary Hodgson may make it easier to link and share designs and models from almost any source, so don't stop sharing and keep it open source.
 If you see any other coverage on the Makerbot Patents, post links below. Thanks.

Other news - 

The 3D Printing Filament spool standard campaign is still going well, updates soon.

E3D Just released the V6 hot-end -I have had one for a while -  it's amazing !

++Lots++ of new things to share with you soon, new printers, extruders, developments and materials :) So long as people don't take them and patent the work as their own...


Rich.

  1. So glad you wrote this up. I saw that patent and came here to look at your original publication date. The audacity is simply amazing.

  2. When I'm so pissed at them right now. I wonder how you could even manage to post such a calm post about it when multiple of 'your' ideas are on the line. Serious respect for you rich

    1. Thanks, and It's not about my ideas, or anything specific to their patent applications, more about key aspects and developments like colour mixing, material mixing, bed leveling and extruder designs that in recent years have been openly documented and are key aspects of Home 3D printing for the future. Stopping or limiting further innovation and design.

      No one in the Open source community wants to see these things tied up in patents by any company.

  4. Great post, putting out there what a lot of people are thinking but scared to say.
    It's truly shocking they and other companies are getting away with it. Their merging with stratasy wont help either they are also bad for this behaviour.
    We just need to ensure any of our inventions ext are well documented which they usually are! The reason 3d printing has come so far so quick is because it's open source home diy inventors and small companies working together and NOT fighting.

    Perhaps we need a quickstarter campaign for a lawyer to challenge these patents!

  5. Here's instructions on how to submit prior art: http://meta.patents.stackexchange.com/questions/105/i-want-to-make-a-difference-how-can-i-submit-prior-art-to-the-patent-office

    Since this has been an ongoing conversation in the open source hardware community, it would make sense to post updates somewhere public regarding what specific articles of prior art someone submitted so that someone else can submit other things and everyone can see if the process works.

  6. Hi everyone,

    ShapeDo is open to anyone who wants to keep their designs open.

    There is a one click import your profile from Thingaverse. Just go to http://shapedo.com/migrate once registered and it will all be imported.

  7. With regards to the contact sensing patent. http://www.freepatentsonline.com/y2014/0117575.html
    Is this relevant and considered prior art: http://forums.reprap.org/read.php?2,129153,129153#msg-129153

    Which also uses, the extruder/hotend tool head as an instrument for collision detection. Where a lot of people before have been using probes.

  8. This is pretty appalling, and the scope of the patents applied for seems to be huge.
    Scanning through the list of applications http://www.freepatentsonline.com/result.html?p=1&sort=relevance&srch=top&query_txt=MakerBot+Industries%2C+LLC&patents=on (75 in all) this looks like a massive grab of prior art. Worse still (in my mind) most of the claims fall short of the other requirement for a patent, in that they are obvious to people skilled in the art.

    Not just the extruder, but as you mention colour switching, designs for hot ends where the claims list things that are common throughout the reprap project such as Teflon liners, removable nozzles. There are patent applications covering net workable printing, where the claims read very similarly to the features offered by BotQueue (https://www.botqueue.com/).. the list gets bigger each time I look.

    It seems to me that this is part of a larger move on the part of Stratasys to lock up the home market and extort licences from the smaller competitors they can't force out of business. The move to sue Affina in December being the first exchange (although slightly Kafkaesque, in my mind; given one of the claims is about the Up! extruder which Makerbot were clearly Inspired by (http://www.pp3dp.com/forum/viewtopic.php?f=3&t=618)).

    I don't think Makerbot ever would have made quite the poster-boys for the open source movement many people would liked them to be (they always seemed a little to ready to take credit where it wasn't due) its really disappointing to where they have ended up.

    As for alternative to Thingiverse (where I post as DoomMeister) YouMagine does look good but I can't see any terms of service anywhere, I would hate to move my designs only to have history repeat itself. If Makerbot really wanted to do well by the community that has grown around Thingiverse they should have (and still could I guess) give it over to an independent trust.

  9. How disgusting selling other peoples designs, surely you have prior act as it was published on the internet and you are renown for mixing filaments? Are the patents worldwide?

  10. After all of this, one somewhat minor thing that upsets me: they are still on the reprap aggregation pipe advertising their closed source printers. I feel that for a while now they no longer fall under the community of reprap due to their closed source crap, and the idea theft they have been doing should bar them from pretending to be a participant.

  11. Some strategies use melting or softening material to provide the layers. Selective optical device sintering (SLS) and fused deposition modeling (FDM) are the foremost common technologies exploitation this fashion of printing. Another technique of printing is to get liquid materials that are cured with totally different technologies. The foremost common technology exploitation this technique is named stereo-lithography (SLA). Thanks for sharing such kind of nice and wonderful collection.

    INTERNATIONAL CONCEPT OF WORK FROM HOME
    Work from home theory is fast gaining popularity because of the freedom and flexibility that comes with it. Since one is not bound by fixed working hours, they can schedule their work at the time when they feel most productive and convenient to them. Women & Men benefit a lot from this concept of work since they can balance their home and work perfectly. People mostly find that in this situation, their productivity is higher and stress levels lower. Those who like isolation and a tranquil work environment also tend to prefer this way of working. Today, with the kind of communication networks available, millions of people worldwide are considering this option.

    Women & Men who want to be independent but cannot afford to leave their responsibilities at home aside will benefit a lot from this concept of work. It makes it easier to maintain a healthy balance between home and work. The family doesn't get neglected and you can get your work done too. You can thus effectively juggle home responsibilities with your career. Working from home is definitely a viable option but it also needs a lot of hard work and discipline.

    Baby-sitting
    This is the most common and highly preferred job that Women & Men like doing. Since in today's competitive world both the parents have to work they need a secure place to leave behind their children who will take care of them and parents can also relax without being worried all the time. In this job you don't require any degree or qualifications. You only have to know how to take care of children. Parents are happy to pay handsome salary and you can also earn a lot without putting too much of an effort.

    Nursery
    For those who have a garden or an open space at your disposal and are also interested in gardening can go for this method of earning money. If given proper time and efforts nursery business can flourish very well and you will earn handsomely. But just as all jobs establishing it will be a bit difficult but the end results are outstanding.

    Freelance
    Freelance can be in different wings. Either you can be a freelance reporter or a freelance photographer. You can also do designing or be in the advertising field doing project on your own. Being independent and working independently will depend on your field of work and the availability of its worth in the market. If you like doing jewellery designing you can do that at home totally independently. You can also work on freelancing as a marketing executive working from home. Wanna know more, email us on workfromhome.otr214426@gmail.com and we will send you information on how you can actually work as a marketing freelancer.


    Internet related work

You can match your time according to your convenience and complete whatever projects you get. To learn more about how to work from home, contact us today on workfromhome.otr214426@gmail.comand our team will get you started on some excellent work from home projects.


    Diet food
    Since now a days Women & Men are more conscious of the food that they eat hence they prefer to have homemade low cal food and if you can start supplying low cal food to various offices then it will be a very good source of income and not too much of efforts. You can hire a few ladies who will help you out and this can be a good business.

    Thus think over this concept and go ahead.
