Re: Heating resin before print

We've done a few tests here with temperature of the resin. One test we did was to put the resin in the refrigerator and then try to print with 45 degrees F resin. Still printed. Not recommended of course but just fyi ;) Viscosity seems to be the main issue below that 50-45 degree point, the resin wo...

Re: Projector drifting out of focus

We now add some tack between the focus ring and the projector housing to help prevent the focus ring from moving. Something like that should help if it is experiencing unwanted movement.

Re: Printer settings have no effect.

This print looks really good. If you are going after the highest detail, having the squares a little smaller will minimize any overexposure. If that is most important, then I suggest not changing any more settings and print some of your own pieces. Otherwise I would suggest increasing the MSM to 1.2...

Re: Calibration file print. Help me!!!

Looks close, a bump up to 1.5 MSM should get you there.

Re: 12HR PRINT FAILING AT 1/2 WAY POINT

Is there any error message that pops up when the print freezes? Projector lights blinking? Or does it just seem to stop with no error message present.

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

Yes, the lens should be parallel to the PDMS surface for the most accurate prints.

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.

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...
