'''Lulzbot'''
 
Lulzbot has an open source bed leveler. http://lulzbot.com
 
==Workshops and Printer Designs Developed for Workshops==
 
'''Prusa Mendel'''
 
It was the first printer to be realistically build-able during a weekend workshop[https://ia600801.us.archive.org/17/items/3D-printing-podcast-prusa-mendel/02-3DPS-josefPrusa-reprap.ogg] (this was 2009-2010). It's printed parts took 10 h to print, compared to the 20 h of its main contester at the time of release, the Sells Mendel[https://ia600801.us.archive.org/17/items/3D-printing-podcast-prusa-mendel/02-3DPS-josefPrusa-reprap.ogg]. Many Reprappers wanted to print printers for their friends at this time, so it received a lot of initial interest for its short print time[http://forums.reprap.org/read.php?1,70314,70447]. It established a reputation as easily customizable.
 
Josef Prusa was active in the community[http://blog.reprap.org/2011/11/prusa-iteration-2.html], listened to feedback and the git repo was updated almost every week. Mean days between commits on master branch: 5.5[https://github.com/prusajr/PrusaMendel]. He would travel the world giving workshops, and managed to pay airplane tickets by pre-selling the printed parts to workshop participants.
 
Estimated number of Prusa or remixed Prusa printers by January 15 2014 worldwide, based on retailers' summed estimates[https://archive.org/details/3D-printing-podcast-prusa-mendel]: ~70000 to 80000 (300 of these printed by Prusa himself)
 
He currently sells printers assembled and kit printers[http://prusa3d.com/] through an OSHW enterprise. Most customers by January 2014 was companies[https://ia600801.us.archive.org/17/items/3D-printing-podcast-prusa-mendel/02-3DPS-josefPrusa-reprap.ogg].
 
'''MOST lab workshops'''
 
The MOST lab has a concept that's very similar to D3D Fusion. They have
*Their own kit and kit supplier
*Detailed online documentation describing both how to [http://www.appropedia.org/Athena_Build_Overview build] the printer and how to [http://www.appropedia.org/Delta_Build_Workshop host a workshop]
*Gathered [http://www.appropedia.org/Evaluation_of_RepRap_3D_Printer_Workshops_in_K-12_STEM data] from workshops
*Free software source code and design files
*A separate Train-the-trainer program
 
==Distributive Ideas and Documentation==
'''Seed Factory'''
Dani Eder had a similar initiative in 2013, called [http://www.seed-factory.org/ Seed Factory]. He wrote a [https://en.wikibooks.org/wiki/Seed_Factories Wikibook] where he introduces several useful concepts and shares lots of engineering knowledge.
 
==Funding Mechanisms for Open Source Work==
The following mechanisms are places online with companies behind them that facilitates/organizes standard bank- or Bitcoin transactions.
Some of them give users Internet tools and space for presenting themselves and/or their projects.
In general, creating them doesn't seem too hard, and the competition seems rough since there exist more than 40[http://kickstarteralternatives.com/] crowdfunding pages in the Internet.
Only a very small selection is presented below.
 
The presented mechanisms don't teach how to do work, they only give technical help with how to ask for money.
 
===Pre-selling/Crowdfunding project-wise===
'''[https://kickstarter.com Kickstarter]'''
lets any (approved) project start a public fundraising campaign online (crowdfunding). All-or-nothing funding model. USA-centric. Manual approval of campaigns based on "creativeness" criteria. Products need not be open source.
 
'''[https://www.indiegogo.com/ Indiegogo]'''
offers less strict approval criteria than Kickstarter. No all-or-nothing model (sometime makes contributions be more like donations that pre-sales).
 
'''[https://www.bountysource.com/ Bountysource] Fundraisers'''
is similar to Indiegogo but focuses solely on developers of free software and OSHW. Bountysource actively helps in connecting with potential sponsors.
 
===Monthly Donations Person-wise===
'''[https://flattr.com/about Flattr]'''
offers a convenient way to donate small amounts on a monthly basis. After registration and filling the Flatter account, setting up monthly donations to another user takes only one click.
 
===Donations Feature-wise===
'''[https://www.bountysource.com/ Bountysource] Founties'''
lets vackers initiate and/or (crowd)fund bounties. Developers hunt these bounties by solving the specified issues or feature requests. Backers judge if solutions are good enough.
 
'''[https://freedomsponsors.org/ Freedomsponsors]'''
is very similar to Bountysource bounties.
 
===Monthly Donations Team/Project-wise===
'''[https://salt.bountysource.com/ Bountysource Salt]'''
Turns donations into monthly salaries for developers of free software and OSHW. To recieve the money, developers promise to spend some number of hours working on the specific project.
'''[https://snowdrift.coop Snowdrift]''' is exploring the idea of network effects (organizes donations so that more backers results in more backing per backer). For free open and libre projects only.
 
= Difficulties =
#Making actual potential workshop instructors in a short time. I (Tobben) have never seen a newbie that became a good instructor in < 1 year. Confirmed by MOST lab having separate (and very detailed) train-the-trainer program.
 
= Counting RepRaps =
The RepRap Project did their own RepRap count in 2010, which they described in their report ''RepRap - the replicating rapid prototyper'':
<blockquote>
Owing to the free distribution of the machine it is difficult
to make a worldwide estimate of the number of RepRaps
and RepStraps there are, but the sale of electronic kits for the
machine (which are also produced commercially) sets a lower
limit of 3000 machines. However, some people construct
their own electronic kits rather than buying from market.
About 4500 machines would seem to be a conservative
estimate of the total population at the time of writing this
paper (i.e., in 2010).
</blockquote>
 
Josef Prusa used similar methods to estimate that there were ~70k - 80k Prusa machines (including derivatives) in 2014.[https://ia600801.us.archive.org/17/items/3D-printing-podcast-prusa-mendel/02-3DPS-josefPrusa-reprap.ogg]
 
== 3D Hub's numbers ==
Source of these numbers is [https://www.3dhubs.com/Trends 3dhubs Trends page] retrieved Jan 5 2016.
 
The reported percentage of Prusa designs is 10.
 
The reported percentage of RepRap-manufactured 3D printers is 15.5. That's about twice as high as what other sources report(should ref here).
This could be explained by RepRap owners being more proud or their printers (they've built them themselves), or by the sharing-minded culture within the RepRap community.
 
We should expect the Prusa count to be as skewed/biased as the RepRap count, which leads us to assume a Prusa percentage of ca 5.

== On Societal Impact of Digital Technology ==
“Digital technologies change
  rapidly, but organizations and
  skills aren’t keeping pace.
  As a result, millions of people
  are being left behind. Their
  incomes and jobs are being
  destroyed, leaving them
  worse off … than before the
  digital revolution...”<ref name="brynjolfsson2012race"/>
