ESTSetúbal, June 2003

RAPID PROTOTYPING TECHNOLOGY

WHAT IS RAPID PROTOTYPING?RAPID PROTOTYPING (RP) IS ONE OF THE FASTEST DEVELOPING MANUFACTURING TECHNOLOGIES IN THE WORLD TODAY. IT IS DIFFERENT TO THE CONVENTIONAL FABRICATION PROCESSES (I.E. SUBTRACTIVE TYPE AS MILLING OR COMPRESSIVE TYPE LIKE CASTING AND MOULDING). UNLIKE THOSE PROCESSES RP IS OF ADDITIVE TYPE, BECAUSE PARTS ARE BUILT ON A LAYER-BY-LAYER BASIS.

THE PROTOTYPES CAN BE MADE FROM PLASTIC, PAPER, WAX, CERAMICS AND METALS, AND, IN GENERAL, RP SYSTEMS CAN BE CLASSIFIED INTO THREE DIFFERENT CATEGORIES BASED ON THE INITIAL FORM OF MATERIALS USED: LIQUID-BASED (e.g. SL); SOLID-BASED (e.g. LOM) AND POWDER-BASED (e.g. SLS).
