Visually is hard to tell the materials apart, except for stuff like carbon fibre infused materials. You can sometimes smell the difference, PLA doesn’t really have a smell but stuff like PETG and ABS does.
The cost would be easier to work out based on weight. A basic off the shelf filament from say Jaycar costs like $20 for a 1kg spool.
The biggest cost factor is print time, how much they charge per hour of print, I don’t know how some calculate their rates though.
I would think the cross hatch pattern would indicate that was base layer, there surface that was on the build plate.
Oh just went back and had a look and saw the requiem, assuming that’s what you were talking about, hadn’t been looking at this thread.
For something that size I’d say total print time probably a day and a half and based on how shiny it looks before paint I’d mostly likely say it’s silk or even a “metal” PLA, which typically go for about $30 depending on brand.
Reminds me as a kid hand drilling out .22 Air Rifle Pellets to fck up the local Parrot population!
Adding a dob of Wax into the drill holes created some interesting results as well!
They just used standard PLA it seems, and only half a spool tota, but little over 24hrs print time is where the cost will come from, electricity and cost of machine maintenance is what determines that cost.
For something that big and intricate it’s not surprising how long it takes.
I couldn’t say on power consumption, I do have one of those metered boards but it’s in storage ATM, don’t think it was that much though, they run on 120 or 240 volts too.
Just looked it up and maximum power consumption is 2050w @ 220v, but it only runs at max during heat up then tones it down, to what I can’t see.
