Q

How does Fused Deposition Modeling (FDM) work?

A

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

Q

How does Laminated Object Manufacturing (LOM) work?

A

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

Q

How does Selective Laser Sintering (SLS) work?

A

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

Q

What are the advantages and disadvantages of rapid prototyping?

A

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

Slow process
Not suited for large scale applications
