Re: Proper projector to back plate angle- V1.2?

The black focus ring isn't a good reference point as it has plenty of potential movement. The actual optic lens would be a better reference point but would require a smaller gauge, and you would have to be careful not to scratch the lens.

Re: More Technical details on B9CORE

You can use anti-aliasing as much as you want, but once shining the layers through the projector you will have accurate 30 micron resolution no matter what you do, that's what you are seeing on the print.

Re: projector upgrade

Like Metalcaster mentioned above, it is a lot of work and most likely some cutting/grinding if you want to actually do this. You are better off to buy a used 1.2. The reason being that the D912 projector used in the 1.2 machine is a lot bigger than the projector on the 1.1, so many of the base metal...

Re: Core 530 vs. 550

The line there is not due to slicing, it is due to soley to having a 50 micron pixel size. Same artifact will be there at 30 microns, just smaller. The yellow ring shown in the other picture (this one) is flat, not curved and therefore it prints.. well.. flat, no artifact to form because there is no...

Re: Resins Data Sheets

Like Robert is saying, If you can change the settings on the machine to essentially cure the resin with more or less energy, you are changing the properties of the piece. It may not be by much, but they will be different, which nullifies the use for that data unless you can maybe find an absolute mi...

Re: Better mesh creation settings for stl file

This is a picture I like to show just to visualize the difference. The pic is talking about z-step, same can be said for x/y resolution.

The HD projector does help. Essentially it makes more lines on a shallow curve, but each one of those lines is thinner.

Re: The B9 Core Series is coming...

The supports will be essentially the same as they are in the current software. Similar to the supports in the pictures you linked. They are the same material cured the same as other parts of the model, but they snap off very easily and by changing the tip you can choose what kind of break you get wh...

Agreed with ak on re-calibrating. Also make sure that you have selected the right resin in the print menu.

Re: Few questions about B9

So, when printing, there has to be a way to control how much energy it takes to cure a slice well enough to print but also maintain an accurate slice thickness. Part of this is via the projector and how long the output of each slice is shone, but it also comes down to the resin properties. For examp...

Re: Few questions about B9

To answer your questions: 1. The z-motor moves in 5 layer steps, this determines the minimum slice thickness of 5 microns. However, finding a resin that control the depth of cure down to 5 microns will be the hard part and your xy resolution is still going to be a minimum of 30 microns. So improveme...

Re: Yellow at 15 microns?

Just because you can doesn't always mean you should :D The yellow is pigmented for 20-50 microns, so 15 is out of the limits that we have determined for this resin. You can still slice that low, but that is mainly a feature used to give some flexibility to the people who like to test different resin...

Re: contamination

I wouldn't think skin contact would make any difference. Either way I would suggest using gloves for resin to skin contact ;)
It could be a number of things though such as clouding PDMS, not enough resin in the vat etc... I guess it depends on what you mean by "Less reliable"

Re: windows 7

Most likely an issue with your graphics drivers on your computer, update those and that should fix the problem.
