Venus 2.0

Hi Guys,

You may remember the first object I printed last year (Venus), I have printed again this week... take a look on the difference...

These are the pics of Venus printed last year....



And this is the new Venus..... with 50 microns resolution.... cool!!!!!!!!


Cheers,

Junior

  1. I used to be a member of Alvaro Fogassa's yahoo group. For some strange reason my membership is no longer working (I dont know why) I am so excited that is possible to build a homemade DLP 3D printer. I really hope you share build instructions soon. Is there a reason why the build info is not shared yet?

  2. Hi Charles,

    Thank you very much for your comments.

    Yes, the main reason is that I am making sure I will not be sued by IP infringement.

    Regards,

    Junior

  3. My jaw just dropped on seeing these incredible prints - these are best prints from a diy 3d printer that I have ever seen

  4. Patents are already suppose to be public knowledge, so you shouldn't be able to get into trouble for publishing a design. Has someone threatened you already?

    What is the build size area?

  5. For those that didn't see them, there are some pics of the printer here: http://www.monogocoro.jp/2010/10/18/diy-high-res-3d-printer.html

  6. Junior,

    I noticed that your yahoo e-mail bounces e-mails back to me. Do you have another e-mail to which I can contact you? Send me a private e-mail to the moderator on the DIY 3D Yahoo! Groups page.

    Thanks!

  7. Charles,

    Hey! If you are having issues with your account on the DIY 3D Printing and Fabrication Groups page, send me (The list owner and moderator who was inspired to create the group by Alvaro's work.) an e-mail via the Group and we will explore what the issue may be.

  8. I just have to echo what others have said here, and offer you some sincere encouragement. It is a wonderful time at present where general technology has advanced to the point where this sort of advanced development is achievable at home by an individual.

    Congratulations, and I hope the scary IP issues don't overwhelm you and prevent details being shared - the world is changing, and information flow is now more free than ever, and this should and is accelerating crowd sourced, or diy if you will, technologies. It is noble, and it will genuinely change the world.

  9. What a tease. You've got me refreshing daily Junior! Please upload more details as soon as you can. I have lots of unanswered questions. For instance, I'd love to know how you keep the build from sticking to the glass, how you handle calibration, and what resins you've tried. Let's see that video you're promising!

  10. I'm not sure about other countries, but in the US the only way you could get in trouble for publishing details about how you built something is if it includes stolen trade secrets or information obtained under a non-disclosure agreement.

    As Livingston said, patents tell the whole world how something works, so you can take stuff from patents and build it and tell others how you built it. You just can't sell or give away the actual things you built with patented ideas. But again, nothing preventing the spreading of the idea itself.

    *Disclaimer: I am not a lawyer.

    Anyway, great work on the printer. Your print resolution is amazing.

  11. congratolations, it is realy the best diy 3d printer...

    keep up good work...

    portuguese-
    Muitos parabens, é realmente um excelente trabalho, estou ansioso por ver os seus proximos trabalhos e o seu video...

    best regards

  12. Brendan, from what I remember he used Teflon coated glass to keep the part from sticking.

  13. Seriously,

    I reallllllly want you to be able to publish this. I have been saving for a MarkerBot kit (as most of the RepRaps seem to die eventually) and would love something like this as an alternative. The cool thing would be transposing your design to the portable DLP projectors and making small and portable 3D printers that work off of Android devices (for the sake of open source).

    What 'Cha think?

  14. You don't actually have to lose a lawsuit to get in trouble. You just need to be put in a position to have to consult a lawyer. Since the consultation costs money it tends to kill the project budget.

  15. wow, that is awesome. I'll take 2.

  16. Congratulations !!!
    You managed to achieve something, that everyone in the open source community was looking for years.

    Personaly i think the density of the liquid material has something to do with the incredible detail of the final object. Since it could allow one layer to blur with the other while curing. But i d love to know more details about how you achieved it.

    If you are affraid about lawduits from bigger companies, i d suggest you to open a paypal donation. Thousands of people would be happy to donate you to fight back.

    The future is open source:)

  17. Very nice! I was impressed by your first effort (the blue resin), and this new one blows me away. I'd love to build one, if you decide to publish your build process. No matter what, awesome work.

  18. This is absolutely amazing. One question, how big are the 2 busts? are they about 2 inches tall? larger? or smaller?

    Thanks

    ReplyDelete
  19. I'm sorry I mean the 2nd Bust, the 1st has a ruler.

    My bad.

  20. Where is the resin sourced? EnvisionTec?

    ReplyDelete
  21. Wow. That is pretty amazing. Very amazing actually... Thanks.

    ReplyDelete
  22. Yeah, DLPs tend to be quite difficult to use because the base technology is kept under lock and key by the originating company.

    Shame really, as I have two bricked DLP projectors here which would be very handy for any number of projects if it wasn't for the unobtainium datasheets.

    IMHO someone should do the hacking community a favour and release them for all to see.

  23. Great work Carlos, put those big corporations to shame!!!

  24. Hi Jose Carlos,

    Congratulations!

    Very nice work!

    In fact it will be wonderful if you could share this project. You could put homebrew 3D printers in a high level.

    Best Regards,

    Alan

  25. What is the exact reason for not sharing all info on your printer and the resin ?

    ReplyDelete
  26. I mean, Lego is (was) patented, still anyone knows how it works...

  27. hi,
    great improve!!!

  28. For long time I saw something great in this field. Typical problem is that the surface tension of fluid and wetting phenomenon will cause the typical problems but you are able to take benefit out of it. Absolutely a great piece of work. Even your current version is great I can see how it can be improved in many ways. Thanks of making your work public.

  29. why not allude to how it's done via metaphor ? people with enough passion will work it out and providing nobody explicitly publishes how it's done after that, it stays outside the purview of patents

    ReplyDelete
  30. Great work Junior!!! Continue this way.

  31. DId you buy the photosensitive resin or did you make it yourself ?

    ReplyDelete
  32. As for 3d printing device, analog mirror laser display could get better resolution? my bed would be a lcos + 1w laser projection. Actually showwx from microvision projects 840x480 image through low power diodes. What about to mod an eyelops lcos projectio (320x240@30$new..) with UV diode? faster curing resin? infinite focus?

About the Project


I have been dreaming about having a 3D Printer at home for many years, but the ones with good quality are not affordable and the low costs just deliver poor quality. Sounds crazy but I decided to build a high resolution 3D Printer by myself at home (people actually said that I was crazy and this was impossible). The funny thing I never saw this type of machines in real life, and still haven’t seen one besides the one I built.

Now that I succeed building the first prototype, the target is to bring this low cost 3D Printer to every home, so we are developing the first affordable one with high resolution.

I hope you enjoy our blog, follow us and you can have this printer in your home soon.
