I need to print some objects that will be subject to high temps around 400-500 deg. Are there and filaments that could do this?

First of all filaments are (from chemical point of view) without exeption thermoplasts, which means that they can melt into a sicky paste and don’t get burned when heating up or just jump from solid to liquid like metals do.

There is NO currently available 3D printer that could print such filaments and there are also no filaments (aka thermoplasts) that can be processed at 400-500 deg (Celsius i guess), resisting such high temperatures would be a whole new level.

If i understand you correct you want parts that resist that high temperatures, then:

-use metal (shapeways or industry companies that might CNC mill your part both is extremly expensive compared to 3d printing)

-use ceramic (look at shapeways, still expensive)

-use lasercut plywood (this depends on geometry and source of heat, if there are no sparks and just temperature then MAYBE plywood gets the job done but be very carefull i can not guarantee that it wont catch fire)

There is Polycarbonate that gets printed at 300°C so if you get the heat source down to lets say 200°C the part would survive for some time but i don’t think it would have a chance in the long run.

Polycarbonate is the by far most heat resistant and 3d printable material that i know of.

Try to be creative with this… Why not print a mould, that you could use to make castings from. The material of the casting can be a chemical reactive matter like a resin, that hardens out and can resist higher temperatures.

Not pure 3dprinting, but may solve your problem.
