Jeff, would certainly be worth doing, although in comparison, how much is carbon fibre 2mm sheet? |

Hi Chris, McMaster-Carr doesn't list metric thicknesses but 1/16" (1.58mm) is $57 and 1/8" (3mm) is $95 a sheet. If I drop the thickness from 1/4" (6mm) to 1/8" (3mm) the Garolite price drops to $15.50. Do you think 2 or 3mm would be thick enough? Cheers Jeff |

Only my opinion, but I think 3mm would be well thick enough. As long as it is rigid, it isn`t under any force! The heat beds weight is next to nothing and it is only function is supporting the heatbed and I suppose having the linear bearing holders screwed to it to run on the rods. I`d go as far to say that the thinner you can get away with the better - lower weight = faster acceleration for the bed. I saw a MendelMax with a thin aluminium bed and that was far too heavy. 3mm carbon fibre could be a good one for sure! J45on - not off topic at all!! Nice one. What is your hotend wrapped in? |
