No matter what I print, there is a sludge film that accumulates on the bottom of the VAT. It gets worse the larger the print is. In other words if the print takes a long time the sludge is thicker and uglier. It is also always thickest at the same shape as the base layer. It’s as if either the UV is WAAAAAY too strong or the negative spaces of the design being displayed on the screen is not blocking the UV as well as other printers. Yes I have tried several settings and tried the same designs on other printers and they work fine. I am at a loss and don’t know what to do any longer……
My last settings for trying to print using Siraya Tech Fast was 4 base layers at 17 sec. exposure and 7 .2 seconds exposure.
I have used 14 second exposure in the perfect conditions and was able to get the print to grab the plate…anything lower and it fails.
I have also tried Lychee slicer to see if it was something with my software but have the same results.
I just received the printer early October and have yet to get anything to print on it and have spent hundreds of dollars in resin, FEP, and clean up materials trying to test and troubleshoot. The thing is so big and slow it takes forever to run tests but now I am at the point of giving up.
