3D Printing and Ophthalmic Edging

What is an STL?

• A type of filament.

• The final sliced file.

• The coding program.

• The initial pre-sliced file.

What is infill means in 3D printing?

• The filament is cut.

• The designed object is turned into layers.

• Extra material printed inside to avoid collapse. We usually print at 20%.

• Extra material printed on the outside of the object to support overhangs.

What happens during slicing?

• The filament is cut.

• The designed object is turned into layers.

• Extra material is printed inside the object.

• Extra material is printed outside to support overhangs.

• Axis

• Nozzle

• Extruder

• Print Bed

What is a nozzle means in 3D printing?

• It is heated to a lower temperature.

• It is the part of the printer that melts the filament.

• It is the part of the printer that pushes the filament down.

• It is the part of the printer that holds the 3D object as it prints.

What are the basic characteristics of 3D Printing?

• 3D objects print from the computer

• 3D objects are created using a subtractive process

• 3D objects are made in layers, it is an additive process

• 3D objects are downloaded and printed from the internet

What is a G-Code means in 3D printing?

• A type of filament.

• The coding program.

• The initial pre-sliced file.

• The final file that the printer reads.

What does layer resolution mean?

• A file type.

• A kind of filament.

• The shape of the object.

• How detailed the object prints.

What is the illustration in Figure 2 means?

• Infill

• Supports

• Filament Types

• Layer Resolution

What are supports means in 3D printing?

• The filament is cut.

• The designed object is turned into layers.

• Extra material printed inside to avoid collapse. We usually print at 20%.

• Extra material printed on the outside of the object to support overhangs.
