a) 3-D printing always works without errors.
b) Personal 3-D printers can use plastic filament to build an object.
c) 3-D printers can be used to make different objects.
d) A 3-D printer moves around to create objects.

Answer 1

3-D printing always works without errors is NOT true about 3-D printing. Personal 3-D printers can use plastic filament to build an object. 3-D printers can be used to make different objects.

Step-by-step explanation:

3-D printing always works without errors is NOT true about 3-D printing. Like any technology, 3-D printing can encounter errors and issues during the printing process.

Personal 3-D printers can use plastic filament to build an object, which is a common and popular material choice due to its durability and affordability.

3-D printers can be used to make different objects by creating layer upon layer of material, allowing for the production of a wide range of complex shapes and designs.

A 3-D printer moves around to create objects by following a digital model and depositing material in precise locations to build the object layer by layer.
