Question 1

What is rapid prototyping?

Answer 1

The production of a physical model of a design using three-dimensional CAD models

Question 2

How does Fused Deposition Modeling (FDM) work?

Answer 2

“Additive” by laying down thin layers of plastic. Filament is heated in a nozzle and drawn on layer by layer (quite slow process)

Question 3

How does Stereolithography (SLA) work?

Answer 3

“Additive” by curing liquid resin with a laser layer by layer

Question 4

How does Laminated Object Manufacturing (LOM) work?

Answer 4

Layers of plastic, metal and paper are cut with a laser. The sliced layers are then glued on top of each other

Question 5

How does Selective Laser Sintering (SLS) work?

Answer 5

“Additive” as a CO2 laser fuses powder layer by layer to create a 3D form

Question 6

What are the advantages and disadvantages of rapid prototyping?

Answer 6

Reduced development time
Reduced costly mistakes (identifies errors before production)
Less waste (for additive techniques)

Slow process
Not suited for large-scale applications
