Windform®, il prodotto più innovativo per la tecnologia più avanzata
Realizzare un prototipo è sempre una sfida, superare i limiti della conoscenza e dell’esperienza. La prototipazione rapida (PR, Layer Manufacturing Technique) rappresenta la tecnica più avanzata per ottenere, in tempi rapidi, il modello finito da sperimentare.
L’area Ricerca & Sviluppo di CRP ha sviluppato nuovi materiali che, applicati alla tecnologia PR di Selective Laser Sintering, hanno dato vita a Windform®: un prodotto che permette di realizzare prototipi perfettamente funzionali per le più diverse applicazioni.
Windform® è un prodotto unico nel settore della prototipazione, non esiste nulla sul mercato con le medesime caratteristiche e performance.
Windform® mette alla prova la vostra immaginazione per le innumerevoli potenziali applicazioni.

Rapid Prototyping Materials comparison |
|
Wednesday 22 August 2007 |
 The comparison is among NOT FILLED Selective Laser Sintering MATERIALS (WINDFORM FX, DURAFORM EX, DURAFORM PA and PA2200), PARTICLES FILLED Selective Laser Sintering MATERIALS (WINDFORM PRO B, WINDFORM PRO, WINDFORM GF, PA320, ALUMIDE, DURAFORM AF and DURAFORM GF), CARBON FIBRE FILLED MATERIALS (WINDFORM XT) and HIGH PERFORMANCE SLA MATERIALS (NANOTOOL and BLUESTONE).
All the previous are trade marks owned by the following companies: CRP Technology, 3D Systems, EOS, DSM Somos.
The comparison is done using the official Technical Data Sheets of each material published by the respective company on each official website.
The comparison is made using Specific Properties (properties per density unit) in order to analyse at the same time the materials’ weight (weight of parts sintered with almost full density): lightness is one of the key properties for the main worldwide Rapid Prototyping (RP) and Rapid Manufacturing (RM) applications.
Besides WINDFORM XT, WINDFORM FX is the material with the HIGHEST
SPECIFIC UTS, higher than the other NOT FILLED SLS MATERIALS but also
than all the PARTICLES FILLED SLS MATERIALS and all the HIGH
PERFORMANCE SLA MATERIALS. On the other side, WINDFORM FX has the
LOWEST SPECIFIC YOUNG MODULUS: this means that it is the most flexible
material even having a very high tensile strength and being the
lightest. NOT FILLED SLS MATERIALS in fact, having low young modulus
values, mainly suit repeated bending and torsion solicitations
(fatigue) and should have an excellent crash resistance and a great
consistence. This means that WINDFORM FX is the material that suits
better this kind of applications.
PARTICLES FILLED SLS MATERIALS are created to have HIGHER SPECIFIC UTS
COMBINED WITH HIGHER STIFFNESS (YOUNG MODULUS). LIGHTNESS is one of the
KEY PROPERTIES for their standard applications. The properties of these
materials are therefore the high resistance at break, the high
stiffness and the lightness. WINDFORM PRO is the best placed one, just
before WINDFORM PRO B AND WINDFORM GF. The other PARTICLES FILLED Selective Laser Sintering
MATERIALS have lower values and are generally heavier.
The HIGH PERFORMANCE SLA MATERIALS’ data proof that they have a HIGH
UTS and a HIGH YOUNG MODULUS, being therefore stiff materials and with
a good UTS. The worse property is the weight for sure: they are all the
heaviest. Moreover they usually are very brittle and fragile, not
suiting therefore repeated solicitations, torsions and crashes.
The Carbon Fibre Filled WINDFORM XT has the HIGHEST SPECIFIC UTS and
the HIGHEST SPECIFIC YOUNG MODULUS AT THE SAME TIME. It means it is the
lightest material with the best compromise among stiffness, resistance
at break, resistance at repeated bending and torsion solicitations and
tensile strength. It is the only material able to reach this level.
This RP material comparison is very useful to choose the right material with the right properties for each application.
