Zikafika pa kusindikiza kwa 3D, pali matekinoloje osiyanasiyana omwe alipo, iliyonse ili ndi mawonekedwe ake apadera komanso ntchito zake. Njira ziwiri zodziwika bwino ndi SLA (stereolithography) ndi SLM (selective laser melting) kusindikiza kwa 3D. Ngakhale kuti njira zonsezi zimagwiritsidwa ntchito popanga zinthu zitatu-dimensional, zimasiyana pazochitika ndi zipangizo. Kumvetsetsa kusiyana pakati pa SLA ndi SLM 3D kusindikiza kungathandize ogwiritsa ntchito kusankha njira yoyenera kwambiri pazosowa zawo.

Kusindikiza kwa SLM 3DImadziwikanso kuti kusindikiza kwachitsulo kwa 3D, ndi njira yomwe imaphatikizapo kugwiritsa ntchito laser yamphamvu kwambiri kuti isungunuke ndikuphatikiza ufa wazitsulo pamodzi, wosanjikiza ndi wosanjikiza, kuti apange chinthu cholimba. Njirayi ndiyoyenera kwambiri popanga zitsulo zovuta kwambiri zokhala ndi ma geometries odabwitsa, zomwe zimapangitsa kukhala chisankho chodziwika bwino m'mafakitale monga zakuthambo, zamagalimoto, ndi zamankhwala.

Mbali inayi,Kusindikiza kwa SLA 3Damagwiritsa ntchito laser ya UV kuchiritsa utomoni wamadzimadzi, kuulimbitsa ndi wosanjikiza kupanga chinthu chomwe mukufuna. Njirayi imagwiritsidwa ntchito popanga ma prototypes, zitsanzo zovuta, ndi magawo ang'onoang'ono opanga mafakitale osiyanasiyana.

Kusiyanitsa kwakukulu pakati pa kusindikiza kwa SLA ndi SLM 3D kuli muzinthu zomwe amagwiritsa ntchito. Ngakhale SLA imagwiritsa ntchito utomoni wa polima, SLM imapangidwira makamaka zitsulo zazitsulo monga aluminiyamu, titaniyamu, ndi chitsulo chosapanga dzimbiri. Kusiyanitsa uku kumapangitsa SLM kukhala yabwino kwa mapulogalamu omwe amafunikira mphamvu, kulimba, komanso kukana kutentha kwa zigawo zachitsulo.

Kusiyana kwina ndi mlingo wa kulondola ndi kumaliza pamwamba. Kusindikiza kwa SLM 3D kumapereka kulondola kwapamwamba komanso mawonekedwe abwinoko, ndikupangitsa kukhala koyenera kupanga zida zachitsulo zogwira ntchito zolimba. SLA, kumbali ina, imadziwika chifukwa cha luso lake lopanga zomaliza zatsatanetsatane komanso zosalala, zomwe zimapangitsa kukhala chisankho chokondedwa kwa ma prototypes owoneka ndi mitundu yokongola.

Mwachidule, pamene kusindikiza kwa SLA ndi SLM 3D ndi njira zopangira zowonjezera zowonjezera, zimakwaniritsa zosowa ndi ntchito zosiyanasiyana. SLM ndiye njira yopangira zida zachitsulo zolimba zokhala ndi zida zotsogola, pomwe SLA imayamikiridwa popanga ma prototypes atsatanetsatane komanso mitundu yowoneka bwino. Kumvetsetsa kusiyana pakati pa matekinoloje awiriwa ndikofunikira kwambiri pakusankha njira yoyenera yosindikizira ya 3D pamapulojekiti ndi zofunikira zina.
