We’ve previously posted about Junior Veloso’s liquid resin 3D printer, which uses a DLP projector beneath a bath of resin to cure an object into its appropriate shape. Junior is reporting a huge gain in resolution from multiple improvements in the design. From our friends at Hack A Day:

He’s keeping most of the juicy bits to himself but he did tell us that the improvement he achieved were due to multiple changes in the process. He tweaked the software to use a more precise curing time, the resin formula has been improved, the ability to isolate pixels without hardening resin around them has been stepped up, and he’s made changes to the way the printer is calibrated and how it lifts the hardened model.

But seeing is believing. The bust on the left was printed with Junior’s old design. The bust on the right is the result from his new printer:

3D Printed Busts

And here’s a comparison of a whistle printed with an FDM 3D printer kit (left) and a whistle created with Junior’s own printer (right):
3D Whistle Comparison, FDM vs. Resin

Junior plans to improve and document the project so that anyone can build one and may even provide kits in the future. Keep an eye out for a Kickstarter project to help fund the final stage of development.

    This project is producing really impressive models, it’s easily the best resolution I’ve seen for a home printer. I hope we see a kickstarter project soon!

    this is absolutely phenomenally incredible.

    soon you can just download 3d files from wikimedia commons and print them out.

    We will be able to print our own homes very soon.

      Someone was experimenting with precisely that using a concrete printer a few years ago…

        Thomas Edison experimented with casting homes in concrete, then nearly 20 years ago I recall seeing someone had built a machine that would extrude concrete a bit like a RepRap.

    I see the 3D printer and all the statue are look great . I hope that you had done to much haed work to make this types of the design .

    Talking about the promising VW of 3D printers by Junior Veloso. Unfortunately this seems to be just another scam !

    On Saturday 14th, he posted a FAQ on his blog, as it is also recorded on twitter. He basically stated the following: 

    1. the price of his kit will be a fraction of the commercial systems, but a bit more expensive than the known DIY 3D printers (makerbot, reprap, ultimaker, up! printer). 

    2. As for the resin, he said that the price WILL be similar to the commercial ones !!!

    3. He is also filling for a patent, thats why he still cannot disclose anything to us, before the patent get issued …

    4. we have to check on him regularly for weeks or even months, due to his pending patent…

    After reading his FAQ, some readers got upset and replied with strong language.  Junior in return, censored his blog.  HE immediately DELETED his FAQ section with the REPLIES. 

    Typical democratic DIY, open source blogger attitude, or not ???  What a lame.

    This interesting info was mentioned in one reply, which really got Jr upset:  

    He claims for a 3D printing machine based on DLP projector solidification of near UV photopolymers. His system design is a hybrid of the familiar Envisiontec and 3D Systems SLA technologies. There is also an italian company he tries to reverse engineer: DWS Systems 

    http://www.dwssystems.com/cms/page.php?27  they use blue-ray instead of DLP.
     http://www.youtube.com/watch?v=cQScgf4QR60&feature=related  
    and of cource EnvisionTec with their famous “Tilt function”

    Reminds you anything? The key to success is not the hardware but the chemistry of curable resins. 

    Anyone with some skills and necessary ball screws and nuts for the XYZ table, a DLP or a laser galvo, some acrylic sheets can build a decent 3D system. As for the software any 3D slicer would do much better than Jr’s VB simple software. Its the resin and it’s cost that makes the difference. Get it ?

    I strongly believe that commercial systems are very expensive. Its their IP resin research that really costs. If someone has the skills to reverse engineer them and publish kit plans under the DIY, open source world, he/she is more than welcomed. I actually hope for a DIY version to happen soon.

    Spread the word, the day for low cost 3D printers is very close.
