Rapid PrototypesRapid PrototypesRapid prototyping is the most common name given to a host of related technologies that are used to fabricate physical objects directly from CAD data
Th th d i i th t th dd d b d t i l i lsources. These methods are unique in that they add and bond materials in layers to form objects. Such systems are also known by the names additive fabrication, three dimensional printing, solid freeform fabrication (SFF) and layered manufacturing. Today's additive technologies offer advantages in many a u ac u g oday s add e ec o og es o e ad a ages a yapplications compared to classical subtractive fabrication methods such as milling or turning: Objects can be formed with any geometric complexity or intricacy without the need for elaborate machine setup or final assembly;for elaborate machine setup or final assembly; Rapid prototyping systems reduce the construction of complex objects to a manageable, straightforward, and relatively fast process. This has resulted in their wide use by engineers as a way to reduce time to market y g yin manufacturing, to better understand and communicate product designs, and to make rapid tooling to manufacture those products. Surgeons, architects, artists and individuals from many other disciplines also routinely use the technology.
Rapid ToolingRapid ToolingThe term Rapid Tooling (RT) is typically used to describe a process which either uses a Rapid Prototyping (RP) model as a pattern to create a mold quickly or uses the Rapid Prototyping process directly to fabricate a tool for a limited volume of prototypes RT isPrototyping process directly to fabricate a tool for a limited volume of prototypes. RT is distinguished from conventional tooling in that:
a) Tooling time is much shorter than for a conventional tool. Typically, time to first articles is below one-fifth that of conventional tooling.
b) Tooling cost is much less than for a conventional tool. Cost can be below five percent of conventional tooling cost.
c) Tool life is considerably less than for a conventional tool.
d) Tolerances are wider than for a conventional tool.
