Computer Science- 3D Printing Test

Who invented 3D printing?

Charles Hull

What does FDM stand for and what is it?

Fused Deposition Modeling, 3D printing process that heats up the filament to its melting point and then uses a nozzle to direct the filament in the design of the printed object

When was 3D printing invented?

1986

What type of printers does Charter have?

PLA printers

What does ABS stand for and why don't we want to use it in the classroom?

Acrylonitrile Butadiene Styrene, can release toxic fumes that require ample ventilation

What does PLA stand for and what is it?

Polylactic Acid, type of filament used in printers that is made of corn

What is SLS and why is it problematic for manufacturing?

Selective Laser Sintering, It's problematic because its creations are very porous due to the imperfections in the the powder being solidified when hit by the laser, creating air bubbles that make the object structurally weaker and more prone to damage, very messy too

What was the first type of 3D printer?

Stereolithography apparatus (SLA), which used a UV laser to cure resin layer-by-layer
