I purchased a moai 130 recently. The website I purchased the machine from said it came with PDMS vat and I ordered a FEP vat at the same time. The MOAI actually came with FEP vat so I now have 2 FEP vats. Both have failed after not much use - basically a crease formed that I thought was cured resin and FEP tore while cleaning.
After dismantling them to replace the FEP it seems like both had FEP that was much thinner than I was expecting - around 50 micron…
I had a A4 sheet of 100micron FEP handy and tried that. It seems tighter and releases more cleanly - especially on the left side of the build volume.
I ordered spare FEP direct from peopoly. The peopoly website says it’s 100microns thick - and comparing to the original FEP it’s much thicker - wondering why both preassembled vats had thinner FEP?
