The definition of open source world, there are many definitions, Chinese much, although this is not sad , but at least it makes me feel a bit uncomfortable , being defined by a look of open source software :
Open Source ( ie open source ) are defined by Bruce Perens ( Debian was one of the founders ) is defined as follows :

● free redistribution (Free Distribution): get the source code then this person may freely distribute the source code .
● source code (Source Code): the program's executable file in the distribution, that must be included with complete source code , or get people to easily post the source code.
● derivative works (Derived Works): people can be so modified source code , in accordance with the license terms for the same case of redistribution .
● original author program source code integrity (Integrity of The Author's Source Code): means a modified version , you need a different version number to do with the original code , respectively, to protect the integrity of the original code .
● any person or body shall not discriminate (No Discrimination Against Persons or Groups): open source software may not be because of their sex , group , national , ethnic , etc. set limits , but if it is the case because the law was an exception ( such as : U.S. government restricted the export of high encryption software ) .
● The program in any field of use shall not discriminate (No Discrimination Against Fields of Endeavor): means not restrict commercial use.
● Distributing License (Distribution of License): If the software is redistributed , it is necessary to distribute the same terms .
● License shall not be dedicated to a particular product (License Must Not Be Specific to a Product): If multiple programs combined into a set of software, open source programs when a single distribution , they will need to meet the conditions for open source .
● License shall not restrict other software (License Must Not Restrict Other Software): When an open-source software and other non- open source software is distributed together ( for example, on the same disc ) , shall not restrict other software licensing conditions to follow the open source license.
● License must be technology-neutral (License Must Be Technology-Neutral): means the license terms shall not be restricted to electronic format is only valid if the paper license terms should also be considered valid.

In fact, I always think that open source if you want to flourish , you need to drive with benefits - illustrates a very simple truth , if you know something about this open source 3D printer , you have the opportunity to earn more money !

I just followed the basic concept of open source . This is the only .

 
Purpose:
Kits can be done DIY. Assembly debugging a relatively high degree of difficulty , slowly enjoy the masochistic pleasure.
Printed ABS plastic parts models and even scrap, are guaranteed to be unique in the world . Your personality , you do not have to care about commonality .
The above two is to give outsiders to see. If you will use proe, 3d max modeling tools like , I congratulate you , this is your artifact. It can be put directly into your drawings kind . You can put aside hobbies with, while the money earned significantly more than happy thing ah ......
