For almost a hundred bucks, I expect this to be high quality and made ceramic or double walled vacuum sealed stainless steel. This looks worse than what some higher end 3d printers can do in a few hours.
There's a lot of armchair experts on manufacturing here.
No it can't be 3D printed, that will never beat injection molding in this use case.
You must be living on the moon if you think this can be made from ceramic/steel for $50.
Sorry but yall haven't got a clue
Oh, damn. I thought it was $85 for all four. I would have maybe laid down that, I am a Lord of th Deep after all. But I didnt know they were plastic...
Which is awesome, but then it shouldn't cost this much.
Unless if it's made of some of the actually ultra high performance plastics, like maybe polycarbonate or carbon fiber reenforced PA-6/PPA for example, but I highly doubt that's the case
