Dear Neil,
The influence of surface orientation on accuracy and roughness has been
investigated in a study published as a technical report by Mike Shellabear
(EOS, Germany) within the RAPTEC project (Brite-Euram BE-2051). Professor
Henderson (Arizona State Univ.) has also published some results on FDM.
Papers from research groups at Univ. Maryland (Arni, Gupta) and Univ.
Austin (Thompson, Crawford) provide interesting insights on how surface
quality of RP parts should be evaluated.
Regards,
