I-Spacer lilaphu eliphefumla kakhulu, elihonjisiweyo, elinamacala amaninzi, elisetyenziswa ekwenzeni izinto ezahlukeneyo ezisetyenziswayo ukusukela kukhathalelo lwempilo, ukhuseleko, umkhosi, iimoto, ukuhamba ngenqwelomoya kunye nefashoni. Ngokungafaniyo namalaphu aqhelekileyo e-2D, i-Spacer isebenzisa amalaphu amabini ahlukeneyo, adityaniswe ngumsonto we-microfilament, ukwenza i-3D "microclimate" ephefumlayo phakathi kwamaleko. Ngokuxhomekeke ekusetyenzisweni kokuphela, iziphelo ezihlukanisiweyo ze-monofilament zinokubaipolyester, i-polyamide or polypropylene. Ezi zixhobo zifaneleke ngokufanelekileyo ukusika usebenzisa iUmatshini wokusika we-CO2 laser. Ukusika kwe-laser ngaphandle koqhagamshelwano kunika ukuguquguquka okuphezulu kunye nokunciphisa amaxesha okucubungula. Ngokwahlukileyo kwiimela okanye iipuntshi, i-laser ayifihli, okukhokelela kumgangatho ophezulu ngokuqhubekayo kwiimveliso ezigqityiweyo.
