High Strength Print Bed for 618 Nylon

I've been using the Garolite Hard and Strong (XX) from Mcmaster-Carr with great success and no heated bed. It was the cheapest version of Garolite and I figured I would see how well it would stick and so far I haven't had any problems with it. If the part is large and 618 squished down it is hard to get off the sheet but, doesn't take very much Garolite with it once I get it off. I also noticed that increasing the first layer speed as usually I run at 35% speed of my other layers will decrease the sticking effect of the Garolite. So if I run my bottom layer at 50 or 60 percent it won't stick nearly as much as lower numbers. What would be nice is if there was a way to make it slow down at the edges and corners and run faster in the center of large prints. That way I wouldn't require the blue tape hatch pattern to keep the parts from being to hard to get off the build platform. I guess there is probably a way to post process the gcode for the first layer with Perl or something like that but, I'm no good with gcode so... I also used the opaque black version and the part number I used was 85315K114. Hope this helps someone else.
Is your Nylon better printed with or without a cooling fan?
Are you interested in coming out with a black Nylon?

The Nylon base will stick extremely well to any cellulous material. Garolite LE is a low cost board material (Sometimes called a "Composite") that is manufactured by soaking a combination of cloth and cellulous fibers in a heat curable resin, then compressing the laminations as heat is added. The result is an extremely stong board like material with a smooth surface. With an increasing number of Industrial users along with Universities and machine shops wanting to print 618 with accurate dimentional and surface flatness qualities, a series of tests were divised using the attached .stl.
As the amount of material printed increases, the applied thermal stress increases on layers below. While other materials did well with prints that had limited first layer surface area, only the Garolite LE performed to the requirments of these organizations. In testing, the Garolite performed to the point of needing to have some of the surface area taped off to "limit" contact with 618 as early parts had to be removed destructivly.
As noted in the attached photo, over 50% of the contact area is taped off from the Garolite to accomodate part removal.
The part is 150mm long, 90 degree wedge, 10mm wide at the top and 2mm wide at the contact surface.
The photo shows a part printed:
1 solid layer
After one hour of cooling, there was less than one thread separation at the the extreme ends and then only one end.
The test part was allowed to normalize for 2 hours and then bowing along the long axis was measured at less than .2mm
