摘要：

To　solve　the　problem　that　traditional　manufacturing　has　blindness　and　uncertainty　of　the　porous　structure,　and　a　design　concept　of　effective　porous　material　was　applied　to　the　actual　manufacturing.　A　design　and　manufacture　porous　scaffolds　structure　method　was　proposed.　The　porous　structure　mechanic　property　was　guaranteed　on　the　basis　of　lower　elastic　modulus　through　design　unit　cell.　Unit　structure　topology　optimization　and　extraction　were　made　by　the　software　of　Optistruct.　Scaffolds　were　obtained　by　repairing　and　arraying　the　software　of　Magnics.　The　porous　scaffolds　were　fabricated　by　selective　laser　melting.　At　last,　the　compression　test　was　done.　A　series　of　experiments　indicate　that　elastic　modulus　and　compressive　strength　values　of　porous　scaffolds　are　in　the　requirements　scope　of　the　bones.　©　2017,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
