Dear RP World,
I have two questions regarding DTM`s Selective Laser Sintering RP process:

1. On their WEB page the process is described as follows:
"... The interaction of the laser beam with the powder elevates the
temperature to the point of melting, fusing the powder particles and
forming a solid mass. The intensity of the laser beam is modulated TO
METL THE POWDER only in areas defined by object's design geometry..."
Does the "sintering" mean that the powder particles actualy melt? Or
only the surfaces of the particles? The surface of an SLS prototype is
described as "porous" so I think the particles are not completely
melted. Is that right?

2. DTM has recently announced their new machine, the Sinterstation
2500. The process chamber has been changed in shape and size. Does
anyone know about the following features?
- Input file formats
- Minimum slice thickness
- Maximum slice thickness
- Laser type and power
Does any of them changed?
