Uma kuziwa ekuphrinteni kwe-3D, kunobuchwepheshe obuhlukahlukene obutholakalayo, obunye bunezici zabo ezihlukile kanye nezinhlelo zokusebenza. Izindlela ezimbili ezidumile yi-SLA (stereolithography) kanye ne-SLM (i-selective laser melting) ukuphrinta kwe-3D. Nakuba amasu womabili esetshenziselwa ukwakha izinto ezinezinhlangothi ezintathu, ayahluka ngezinqubo zawo nezinto zokwakha. Ukuqonda umehluko phakathi kokuphrinta kwe-SLA ne-SLM 3D kungasiza abasebenzisi bakhethe indlela efaneleke kakhulu yezidingo zabo ezithile.
Ukuphrinta kwe-SLM 3DOkwaziwa nangokuthi ukuphrinta kwe-3D kwensimbi, inqubo ehilela ukusetshenziswa kwe-laser enamandla amakhulu ukuze ukhethe ngokukhetha futhi uhlanganise izimpushana zensimbi ndawonye, ??ungqimba ngongqimba, ukuze kwakhiwe into eqinile. Le ndlela ifaneleka kakhulu ukukhiqiza izingxenye zensimbi eziyinkimbinkimbi ezinamajiyometri ayinkimbinkimbi, okuyenza ibe ukukhetha okudumile ezimbonini ezifana ne-aerospace, ezezimoto, nezokwelapha.
Ngokolunye uhlangothi,Ukuphrinta kwe-SLA 3Disebenzisa i-laser ye-UV ukwelapha inhlaka ewuketshezi, iyiqinise isendlalelo ukuze yakhe into oyifunayo. Le ndlela ivame ukusetshenziselwa ukwakha ama-prototypes, amamodeli ayinkimbinkimbi, nezingxenye zokukhiqiza ezincane ezimbonini ezihlukahlukene.
Omunye umehluko omkhulu phakathi kokuphrinta kwe-SLA ne-SLM 3D usezintweni ezisetshenziswayo. Ngenkathi i-SLA ikakhulukazi isebenzisa ama-photo-polymer resins, i-SLM yakhelwe ngokukhethekile izimpushana zensimbi ezifana ne-aluminium, i-titanium, nensimbi engagqwali. Lo mehluko wenza i-SLM ilungele izinhlelo zokusebenza ezidinga amandla, ukuqina, nokumelana nokushisa kwezingxenye zensimbi.
Omunye umehluko yizinga lokunemba nokuqedwa kwendawo. Ukuphrinta kwe-SLM 3D kunikeza ukunemba okuphezulu kanye nekhwalithi engcono yangaphezulu, okuyenza ifaneleke ukukhiqiza izingxenye zensimbi ezisebenzayo ezinokubekezelelana okuqinile. I-SLA, ngakolunye uhlangothi, yaziwa ngekhono layo lokudala ukuqedwa okunemininingwane eminingi futhi okubushelelezi, okuyenza ibe yinketho ekhethwayo yama-prototypes abukwayo namamodeli wobuhle.
Kafushane, ngenkathi kokubili ukuphrinta kwe-SLA kanye ne-SLM 3D kungamasu okukhiqiza okungeziwe abalulekile, abhekelela izidingo nezinhlelo zokusebenza ezahlukene. I-SLM iyindlela eya phambili yokukhiqiza izingxenye zensimbi eziqinile ezinamadizayini ayinkimbinkimbi, kuyilapho i-SLA ithandwa ngokwakha ama-prototype anemininingwane namamodeli abukekayo akhangayo. Ukuqonda umehluko phakathi kwalobu buchwepheshe obubili kubalulekile ekukhetheni indlela yokuphrinta ye-3D efaneleke kakhulu yamaphrojekthi nezimfuneko ezithile.
