      I seem to remember that you can get granite surface plates fairly cheaply these days though.

      Get's expensive once you add the cost of the hydraulic lift to raise and lower the plate 🙂
      On the bright side, it would be a real solid printer approaching a ton .....

      ... and you are right, I had forgotten that we want to stick a heater on the bottom so carving things out to reduce weight is not an option.

      Just out of interest, I checked the cost of granite surface plates here in the UK. 1,000mm x 1,000mm comes at a thickness of 150mm, cost is about £1,850 and it weighs in at 450 Kgs. 🙂

          That's cheating if you leave the bed plate stationary .....

            Ot of curiosity, how long does something like that take to heat up with ummmm a 3KW heater ?

              @jens55 About 1 and a half hours. Source: https://www.warmlyyours.com/en-CA/countertop-heater

              You didn't specify the temperature.

                  @jens55 that's 11/2 hrs to gain 20 deg F. So to go from say 20 deg C to 60 deg C would take about 6 hrs assuming that heater would go that far. But then counter tops aren't normally 150mm thick like a granite surface plate so I'd say multiple that by 5 giving around 30 hours (and probably about the same amount of time to cool again).

                      Maybe you can find a cheaper one at your local tombstone makers? They often have 2nd hand stones 😬

                        @slimshader hey thanks for the insights. I'm not a first time builder, and all of these "safety" aspects are built into my current (pardon the pun) 525x525x8.5mm build plate.

                        8.5mm? Yep it was an extruded aluminium plate milled down from 10mm to until had <= 0.1mm deviation across the surface. This is kinematically mounted, so expansion is taken into account. Mains powered/SSR, of course, fuse, of course.

                        Weight is easy to calculate once I know a thickness that is required to reduce the bowing to an acceptable level.

                        Thanks again.

                          @theruttmeister yep much of what you've said on aluminium I've either done on previous build (525x525 + kinematic mounts). The granite is a fascinating idea too.

                          Here in Perth, Western Australia, we focus on getting iron ore out of the ground. So buying a tipping tray for a 250tonne capacity hail pack is easier than getting MIC6. Typically we have to wait weeks. Also shipping interstate at rates where shipping doesn't rise above material cost, can take weeks, if needed the thing you want is available in country.

                          So sometimes we have to get creative 🙂

                            @jens55 I do like the look of that. Reminds of the Jubille. Very clean build.

                            Cheating? Who made the rules? 🙂

                              @o_lampe I did contact one tombstone supplier, but they were a dead loss!

                              I don't know if it was CoVid invoked, but the guy couldn't stop coffin. (ouch)

                              I think if anybody could make a printer lift a monolithic build plate, it would be @deckingman 😉

                                  So the best answer to the question sounds like ~22mm

                                    I am glad you like that build .... alas, it isn't my build. I seem to think that @Tinken posted the picture.

                                      Talk to a a supplier out of china. You can get just about any thickness and size. Getting something from a supplier like Starret requires you convincing them to violate all their company values.

                                      Heck, I'd probably start by going to my local kitchen granite store with a straight edge. You'd be shocked how flat just regular granite slabs are once they polish them.

                                      And the 305x305mm granite bed I built back in the day took 4-8 times longer to heat up and probably even longer to cool down, compared to MIC6.

                                      Here in Perth, Western Australia

                                      we live in the most remote city in the world

                                      So sometimes we have to get creative 🙂

                                      I lived in the Other Perth once, long ago. Not as much sun, but much more convenient... for just about everything!

                                      Isolate, substitute, verify.

                                        I applaud your ambitions efforts, but your expectations for a flat heated bed of this size are unreasonable withough significant expense and fabrication.

                                        Speaking as someone who has the both the schooling, academic references and software for analysis and design this sort of thing, and the access to the tools, equipment and material suppliers for what your are asking, i would advise against it.

                                        Look a the various videos on youtube for surface plate calibration and look the ribbing on the cast iron ones and the thickness of the granite ones.

                                          I went to a graveyard and there were a bunch of guys walking round and round with a coffin. They'd obviously lost the plot..........
