Donations

Why donations?

Slic3r is almost a one-man job. I started this project in September 2011 and it's now very well-known and used by thousands people all around the world. I spent much time on development: it was more or less a part-time job for me. I'm a freelance developer, and reserving time for such a project has costs for me.

Ohloh estimates the total cost of having developed Slic3r so far (although this has to be taken with a pinch of salt) at nearly $416k, with an estimated effort of 8 year/man. This is probably too much, but you get the idea. I could have kept the code closed and started selling licenses, but I decided to share my work with the community.

In the RepRap community, many people cover their costs by selling hardware. They honor the free software licenses, by publishing their designs, but they can also sell material things (kits, printed parts, hotends, heated beds, electronics etc.) to fund and continue their research. Software developers... well, they can't sell anything :-)

I believe that building a new, fast, flexible, easy to use slicer is a fundamental contribution for the whole RepRap project. It also gives a boost to companies selling kits and printers.

What will donations be used for?

I only use donations to fund my RepRap-related expenses. Plastic, for example, which is necessary to test a slicer, and new hot-ends to ensure hardware compatibility.

Benefits of donating

  • Your donation will be acknowledged in this website (unless you ask not to be listed)
  • A warm fuzzy feeling inside, knowing that your donation is helping a good project ;)

Can I become a corporate sponsor?

Sure. I'm open to anything that complies with Slic3r's free software license and with the interest of the project. Contact me and let's talk about your offer.

Do I get tax relief on these donations?

No, I'm not a registered charity so donations are not tax-deductable in any juristictions I'm aware of.
