Card 1
Question: What is 3D printing in simple terms?
Answer: A technology that creates objects in three dimensions by following a computer-designed template, building the object layer by layer from a material th
Card 2
Question: Why has public interest in 3D printing grown recently?
Answer: Because printer prices have been falling and usability/applications are broad, attracting not only engineers but the general public.
Card 3
Question: What are the two main types of printable materials mentioned?
Answer: Filament and resin.
Card 4
Question: What is filament in 3D printing?
Answer: A coil of plastic string that is melted and layered to form an object.
Card 5
Question: What does 'additive manufacturing' mean in the context of 3D printing?
Answer: A manufacturing process where material is added layer by layer to build an object.
Card 6
Question: What does FFF/FDM stand for and why is it important?
Answer: FFF stands for Fused Filament Fabrication (also called FDM). It's the most widespread and cheapest 3D printing technology, using melted filament to bu
Card 7
Question: Name two disadvantages of FFF/FDM printing.
Answer: Long printing times and print quality strongly depends on the printer.
Card 8
Question: Give the simplified Czech analogy for how FFF/FDM builds objects.
Answer: The model is sliced into layers like potato chips, then each slice is drawn with a glue gun-like nozzle, building the object layer by layer.
Card 9
Question: What is SLA and how does it differ from FFF/FDM?
Answer: SLA (stereolithography) uses liquid resin and light to create very accurate, precise prints. It's more complicated, uses toxic resin during printing,
Card 10
Question: Why is SLA commonly used in medicine and detailed development?
Answer: Because it provides extremely high accuracy and precision required for items like tooth prostheses.
