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.

now i would really like to try a 256 mm³ cube

That's a cube measuring ~6.5mm x 6.5mm x 6.5mm...I know the A1 is small, but that seems fairly unambitious.

Fuck you right. 😂 Damn you, volume law! I mean 256 mm * 256 mm * 256 mm (so more like 16,7 Million mm³)

[–] Fedegenerate@fedinsfw.app 1 points 23 hours ago

This always trips me up. Would the correct way of writing: a cube 256mm to an edge

256³mm³? That feels inelegant.

Do the math myself so 1.67*10⁶mm³? Which seems like I'm asking the reader to simplify what I complicated.

Or 256mm³? That seems true to speech it's a 256mm cube...

If you go for something like lightning infill of 15% and 3 walls, you could probably make that print in something like 11h and only use 750g filament.

If there were ever a poster child for printing something with a 0.4mm layer height of possibly even more, it may be this. One wonders how much infill you'd need to make it strong enough to sit on. Otherwise, I don't know what the heck you'd do with it.

[–] ExcessShiv@lemmy.dbzer0.com 1 points 1 day ago (1 children)

If you're a "regular sized adult" I honestly think you can get away with 30% adaptive cubic, and 5-6 walls and top/bottom layers.

That's pushes it to 2.4kg filament and a +2 days print though with a regular 0.4mm nozzle and 0.3mm layer height.

[–] dual_sport_dork@lemmy.world 2 points 1 day ago (2 children)

Sounds plausible to me. On reflection, I think I'd just run off a wooden box on my table saw if I need a cube to sit on.

My problem, as I'm sure many others have, is admitting when 3D printing something probably isn't the best solution...

[–] ExcessShiv@lemmy.dbzer0.com 2 points 1 day ago

Yeah I agree, 3d printing is not the right tool for a simple large box.

There are many good applications for FDM printed items. But I still have a metal lathe, mill, drill press, and welders for all the other times that FDM is a poor choice.
