Q

What does the filament do in filament printing?

A

It melts in the print head and creates the 3D object layer by layer.

Q

What is the key difference between filament and resin printing?

A

Resin printing uses liquid resin and light to harden layers, while filament printing uses melted filament.

Q

How does stereolithography (resin) printing work?

A

The build platform moves into liquid resin, where UV light or a laser hardens the resin to create each layer.

Q

What is the print bed in 3D printing?

A

A large flat surface used to build the 3D object, either adhesive on the bottom for filament or on the top for resin printing.

Q

Why does the print bed need to be completely level and still?

A

To ensure the object being printed stays in place and doesn’t move during the printing process.

Q

What is the print bed like for filament printing?

A

It’s a large surface that is sticky to keep the object from moving.

17
Q

What is the print bed like for resin printing?

A

A small area at the bottom of the printer where the light hardens the resin.

18
Q

Why is the print bed smaller in resin-based printers?

A

Because the print bed is the area where the light hardens the resin.

19
Q

Why must resin in SLA printing be handled carefully?

A

It requires protective gear, and leftover resin must be taken to a hazardous materials facility.

20
Q

What is the function of the print bed in filament and resin printing?

A

To provide a stable surface for building the 3D object, ensuring it stays in place during printing.
