Is there a fast likeness of a 3d printer?

Question

3D printers

Now 3D printer manufacturers promise good printing accuracy, but printing takes hours even for not very large models. Are there any solutions that provide high print speed at the expense of low accuracy? Capable, say, in a maximum of 5-10 minutes to print an object with a volume of 800cm ^ 3 and with a print area of ​​at least 50x30x20cm.
Thank you.
upd:
The problem is that not the same model is printed, but something new every time. Let's say a 3d model of some bone is being made based on a tomogram / x-ray or the like, and it needs to be printed right away, the faster the better.
