What is the first step in all 3-D printing processes?

What are medical applications of 3-D printing?

What does the time of the printing process depend on?

What makes large 3-D printing machines useful?

Medical applications of 3-D printing also have a lot of potential.

What are the materials largest and most expensive 3-D printing machines work with?

3-D printing process starts with calculating how each layer needs to be constructed.

In what fields are modern largest and most expensive 3-D printing machines popular?

3-D printing can't produce custom-made metallic and plastic parts to be used as artificial implants.

Largest and most expensive 3-D printing machines are capable of directly producing complex plastic, and metal and alloy components.

3-D printers build objects layer by layer, just like printing in three dimensions.
