Because the insurance company already paid them way more than it’s really worth. And if the insurance company has agreed to pay that much, it’s because they’re making more than enough profit off their “service” to everyone that they can afford to pay it.
If your medicine used to cost $60 and now costs $5000 thst’s because the insurance company knows they can get that money from its customers.
3D printers can move very fast. They typically don’t because it causes all kinds of deformations in the print. Mostly the issues are in acceleration, decelaration, cornering, and controlling the heat snd flow of melting filament.
I don’t know whether or not the accelerometer thing can be done in real time, or if there would be any benefit.
Check out the 2-minute Benchy for an example of how fast a 3D printer can get. This is a test print that typically should take about 45 minutes to an hour at very basic settings.
But also note the quality of the end product. It looks pretty awful. If we could print accurately at even remotely similar speeds, it would be fantastic.
