An external and independent lab analysed the behaviour of WINDFORM® XT in order to proof its reliability and good strength even at medium-high temperature: a behaviour completely different from all other materials used with Rapid Prototyping techniques. Its behaviour, as you will read below, is the same as PA6 BG-35, high performance material for injection moulding and used for production of final parts, for Automotive Industry for example. This is the only and real proof that Rapid Manufacturing with WINDFORM® XT has become a fact, no more simple words.

Study range has been defined to match as close as possible engine top head conditions.
- 5 typical temperatures :
  60 deg C, 90 deg C, 110 deg C, 120 deg C   150 deg C
- Keep in thermohygrometric enclosure for at least 90 minutes to reach target temperature before stress
- Tensile Strength, Yield Strength and E-Modulus have been chosen as   
reference of correlation.

Around targeted temperature range, defined as top head engine area with value from 80 deg C to 140 deg C, WINDFORM® XT material shows similar handling and property to PA6 BG35: stable evolution and predictable in advance.
See below representation of this range.

Compared evolution for PA6 BG-35 and WINDFORM® XT in function of temperature : Tensile Strength

In particular, to be underlined the quite slow decreasing of WINDFORM® XT strength value between 90°C and 120°C and also the good value at 120°C, that is almost the value that standard pure PA12 for laser sintering has at 20°C!

Compared evolution for PA6 BG-35 and WINDFORM® XT in function of temperature : Yield Strength

The Yield strength behaviour highlights the incredible reliability of WINDFORM® XT: no unexpected lost of performance or breaks!

Compared evolution for PA6 BG-35 and WINDFORM® XT in function of temperature : Young modulus

Between 90°C and 120°C the WINDFORM® XT modulus has almost no decrease and the value underline that WINDFORM® XT at 120°C is almost two times stiffer than standard pure PA12 at 20°C!
