Winner printed with B9 Core 530

We've had our Core 530 for a year now and I'm still amazed at the print quality I get from this printer. I designed this fun piece with T-splines/Matrix and printed it in 5 parts on the core 530. Thanks to the Schmitt's, B9, and our awesome craftsmen in the shop for bringing this design to life.

Re: 3d scanner use for making shadow bands

I've been using the "trace edge" method since 2004. Unless you are doing a ridiculous number of shadow bands I would suggest saving your money. Daniel Coffey has a very nicely made youtube tutorial on shadow bands.

Re: Emerald Resin Curing for Casting

OK thanks Mike. All of my model and calibration measurements are dead on so I don't intend to change my MSM. I'll just continue curing in the microwave and then the light box. Whatever works. :D

Re: Emerald Resin Curing for Casting

I too have noticed that my B9 light box is not curing Emerald green in 2 minutes. As soon as I received the B9 Light box I cured several light pieces for 2 minutes. They were still rubbery so I cured them 9m50sec and again 9m50sec.They were still rubbery. I was not going to attempt casting a rubbery...

Re: One bad quad

Check to see that your PDMS coating is parallel to the slide rails. I call this the "rat chew effect" and first saw it on a factory coated vat. The pdms had an uphill slope towards the cliff side. My logic is that the model is compressed into the PDMS as the vat slides and then snaps over ...

How many supports do you use?

I almost always bring the supports to the bottom inside of the shank and angle all others to prevent PDMS burn. http://www.b9c.com/forum/files/uploads/2014/12/3gj8o-Supports2.JPG http://www.b9c.com/forum/files/uploads/2014/12/35put-Supports.JPG http://www.b9c.com/forum/files/uploads/2014/12/u99yi-Su...

Glass loosening from vat....

My new red B9 vat is like that too. I noticed it before recoating the first time so I just pressed lightly from underneath to allow pdms to seap in and seal it. It is the glue bead along the waterfall edge of the glass.

HD Projector problem??

First let me say that the new B9 v1.2 is amazing. The prints are superior to the v1.1. Great job Mike! Second, I want to say that Mike has already agreed to replace this projector but before doing that I wanted to see if anyone else is having this issue or possibly have an answer to what is causing ...
