shapeways: professional or versatile?

[Mr. ED]

Hey guys,
who has tried both options? And what can you tell me about each?

looking at the website and the datasheets, the professional is multi-jet (HP) technology powder, intended to be used for the HP printers.

the versatile plastic is for the SLS process and the non HP printers.

both materials are polyamide, aka nylon, but there are a number of formulas. their mechanical characteristics are very similar, but the HP datasheet shows the parts are more dense with their process. More dense = potentially stronger.

[Mr. ED]

Thank you both.

That's crazy: they are offering the HP MJF stuff at nearly double the price.
The service providers I looked at have the MJF stuff priced even a bit lower than SLS

obtained from the other provider: a link to a technical document describing the MJF material (PA12) properties:
