Alternative designs to replace MDF

RepRapPro advice

I print on a standard bed, but have long screws in the 2 points at the back (along the Y extrusion) and one at the front, between the bed terminals, so it's mounted on 3 points. The screws are 25mm cap screws, that go down through the aluminium heat spreader, then bed PCB, then have an M3 washer and M3 nyloc nut. A nyloc nut is threaded on lower down, and acts as a height adjuster. Then it goes through the MDF, and a plain M3 nut on the back, to lock the it in place. The outer corners just have a short cap screw though the heat spreader and PCB, with an M3 nyloc on the back, which doesn't touch the MDF below. I have the cardboard taped to the back of the PCB, as per the instructions. This means the outer two corners don't support the bed, and I have adjustment over the bed plane. I advise people who contact me with bed problems to do this, because mostly it's the two unsupported corners of the MDF that cause the problems if the MDF warps. There is scope for the back two corners to droop a bit, but nowhere near as much as the front corners. You can even cut the front two corners off the MDF if you want, leaving the MDF as a 'T' shape.
