Since people wanted to see how it turned out. This is a 330x330 object that covers the entire purported print area of my machine.
I’m ashamed to admit that I undershot my filament usage calculation slightly, and I chickened out just before the finish line. I didn’t have any more white in stock, so I switched to some grey of the same type from the same manufacturer by doing a mid-air refuel, shoving the end of the new spool in chasing behind the very tail of the old one. I don’t think it looks too bad. I may just spraypaint the entire thing white later anyhow. I wanted to use a light color in order to more easily spot and keep track of screws and springs and such.
I think the grey edge looks better than 100% white. Things like this are the reason I have AMS, all my prints are functional and could be done in one color, they just look better when they’re not. And if it’s for screws and hardware, they’re going to be down in the white where they’ll contrast, not hiding up on the edge.
Yeah, the grey looks great. Just the right ammount, imo.
I am impressed that the edges of your build plate are hot enough to keep the corners from curling up. This is a problem I fight on any print that is close to an edge.
I can’t speak for other printers, but my X-Max 3 has an absurdly thick aluminum plate under there which seems to spread the heat pretty well. I’ve poked it with my little IR camera and it’s not 100% even but it’s not bad. The only side effect of this is that it takes a month of Sundays to fully reach temperature, especially when you’re aiming for higher temperature materials like ABS.
Here it is on today’s preheat for PLA:

WOW! That is super even. I looked at mine with a FLIR attached to my phone, and it had definite hot spots. It might be time for a new heat bed.

The stock 350mm Voron bed is 5/16" (8mm) thick. It’s quite hefty lol
Qidi x- max 3?
Exactly so.
