The problem with Lexan is that it cools really, really quickly. To make a decent moulding you ideally need to keep it heated throughout the forming process. Not that easy! Good luck!

yeah, what he said. If you are using vac former, you will find you get better results if you heat the forming tool up as well. It will allow the sheet to stretch so it doesn't go all thin round the edges

I had an absolute nightmare using a standard top heating vac former with lexan. By the time I'd removed the heater the stuff had cooled!

I had to dismantle the safety bits on the machine i use so i could keep the heating elements in place while forming. doing that and bodging it together with a serious vacuum pump did the trick.
