Those look nice! What orientation did you print them in? (It looks like there are some lines on the righthand piece running vertically from the sprue base; are those layer lines?)


Upgraded my Z axis to a higher quality and the banding is pretty much gone. These prints are at the same 50 micron. WaxCast is working out well so far!
3.5 sec layer time @ 50 micron.

Very nice, thanks for sharing! Regarding the 3.5 second layer time, have you removed your projector's UV filter or color wheel, or is that stock?

I relocated the color wheel so it is out of the light path. The difference in print time is significant!

B9 makes B9's resin (Or has it made custom...). They have the MSDS on their website.

The WaxCast casts exactly like wax with no ash and a smooth surface. However...it MUST be cured all the way...meaning it has to be almost yellow. I can post some castings in a few days. I hade some rough surface castings initially when I did not let the resin cure (it was still too orange..and it reacts with investment giving a very rough texture) ...had the same issues with the B9 Cherry/Red when it is not cured...

B9 has a light they sell that will fully cure their resin and I am told WaxCast as well. There are other means of DIY coating that will seal pretty much any castable resin eliminating the need for curing.

Incidently, I have used both Cherry/Red from B9 and WaxCast and they both are castable when fully cured. I prefer WaxCast because you can literally see the wax in it. It also doesn't settle.

B9 has newer Yellow/Green that people are casting very well...but I have not personally tried it.
