In　Selective　Laser　Micro　Sintering　the　powder　particles　should　be　assembled　or　arranged　and　sintered　together.　Optical　tweezers　make　used　of　optical　refractive　force　to　manipulate　micro　objects.　Currently　the　manipulated　objects　are　limited　to　nano　or　several　micro　meters　scale.　In　this　paper　we　develop　a　novel　optical　tweezers　which　employs　pulse　laser　force　to　drive　bigger　particles　and　assemble　them.　This　pulse　laser　is　controlled　to　form　spiral　trap　which　can　grasp　big　particles.　In　our　experiment　the　50um-100um-diameter　metal　particles　were　moved　on　a　solid　surfaces　in　a　process　we　call　＇laser　spiral　driving　force＇.　Nearly　any　shape　particle,　including　sphere　and　non-regular　shape,　can　be　moved　on　the　surfaces.
