Xa kuziwa kushicilelo lwe-3D, kukho iindlela ezahlukeneyo zobuchwepheshe ezikhoyo, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa. Iindlela ezimbini ezidumileyo zi-SLA (stereolithography) kunye ne-SLM (i-laser ekhethiweyo enyibilikayo) yoshicilelo lwe-3D. Nangona zombini iindlela zobugcisa zisetyenziselwa ukudala izinto ezintathu-dimensional, ziyahluka kwiinkqubo zabo kunye nezixhobo. Ukuqonda umahluko phakathi kwe-SLA kunye ne-SLM 3D yoshicilelo kunokunceda abasebenzisi bakhethe eyona ndlela ifanelekileyo kwiimfuno zabo ezithile.

Ushicilelo lwe-SLM 3Dekwabizwa ngokuba yintsimbi ye-3D yoshicilelo, yinkqubo ebandakanya ukusetyenziswa kwelaser enamandla kakhulu ukunyibilika ngokukhetha kunye nokuxubha umgubo wesinyithi kunye, umaleko ngokomaleko, ukwenza into eyomeleleyo. Le ndlela ifaneleke ngokukodwa ukuvelisa iinxalenye zentsimbi ezintsonkothileyo ezinejometri entsonkothileyo, iyenza ibe lukhetho oludumileyo kumashishini afana ne-aerospace, izithuthi, kunye nezonyango.

Kwelinye icala,SLA 3D yoshicileloisebenzisa i-laser ye-UV ukunyanga intlaka yolwelo, iyenza iqine umaleko ngokwemaleko ukwenza into efunekayo. Le ndlela iqhele ukusetyenziswa ekudaleni iiprototypes, iimodeli ezintsonkothileyo, kunye neendawo ezincinci zemveliso kumashishini ahlukeneyo.

Omnye umahluko ophambili phakathi kwe-SLA kunye ne-SLM 3D yoshicilelo ilele kwizinto abazisebenzisayo. Ngelixa i-SLA ikakhulu isebenzisa i-photo-polymer resins, i-SLM yenzelwe ngokukodwa umgubo wentsimbi onje nge-aluminiyam, i-titanium, kunye nentsimbi engenasici. Lo mahluko wenza ukuba i-SLM ilungele izicelo ezifuna ukomelela, ukuqina, kunye nokumelana nobushushu bamacandelo esinyithi.

Omnye umehluko lizinga lokuchaneka kunye nokugqiba umphezulu. Ushicilelo lwe-SLM 3D lunikezela ngokuchaneka okuphezulu kunye nomgangatho ongcono womphezulu, okwenza ukuba ilungele ukuvelisa iinxalenye zentsimbi ezisebenzayo ezinokunyamezelana okuqinileyo. I-SLA, kwelinye icala, yaziwa ngobuchule bayo bokwenza umphezulu ocacileyo kunye nogudileyo, nto leyo eyenze ukuba ibe lukhetho olukhethwayo kwiiprototypes ezibonakalayo kunye neemodeli zobuhle.

Isishwankathelo, ngelixa zombini i-SLA kunye ne-SLM 3D yoshicilelo zizixhobo ezixabisekileyo zokuvelisa ezongezelelweyo, zibonelela ngeemfuno ezahlukeneyo kunye nokusetyenziswa. I-SLM yindlela yokuya ekuveliseni iindawo ezomeleleyo zentsimbi ezinoyilo oluntsonkothileyo, ngelixa i-SLA ithandwa ngokudala iiprototypes ezineenkcukacha kunye neemodeli ezinomtsalane ezibonakalayo. Ukuqonda umahluko phakathi kwezi teknoloji zimbini kubalulekile ekukhetheni eyona ndlela ifanelekileyo yoshicilelo lwe-3D kwiiprojekthi ezithile kunye neemfuno.
