Hi Scott,

EOS has offered the Alumide material since December 2003. The material is a mixture of nylon and aluminum powder (30% aluminum by volume) and is processed on the company's plastic laser sintering (EOSINT P) machines. The Centre for Rapid Prototyping and Manufacturing at Central University of Technology, Free State (South Africa) uses Alumide regularly.

  Hi Everyone.


  I am looking for information about / personal experiences with the Aluminum Filled Polyamide material that is available for SLS machines these days.


  I don't have any specific questions about it, but rather just wanted to know if anyone wanted to add their 2 cents on the topic.



  Well . .wait a minute. I do have a specific question.

  At the SME meeting in Dearborn, when RP parts were collected from vendors to build a small toy combination safe.

  My safe has its mainbody made out of what looks like aluminum filled plastic material.

  Although it has the EOS logo on it. I didn't know EOS had anything besides regular and glass filled PA.

  A quick look on the EOS website doesn't tell me anything about their materials.

  (Granted I didn't look TOO long. But then if it is a good website . .I shouldn't have to spend half an hour looking for information about their materials)


  Thanks in advance for any information.
