Ibiranga UV

(1) Ubukonje buke.Gukiza UV gushingiye kuri moderi ya CAD, kandi ibisigarira byashyizwe kumurongo kugirango bibe ibice.Igice cya mbere kirangiye, biragoye ko resin yamazi ihita itwikira hejuru yubutaka bukomeye bwakize, kubera ko ubuso bwubuso bwibisigarira buruta ubw'ibisigara bikomeye.Urwego rwa resin rugomba gukurwaho no gutwikirwa rimwe hamwe na scraper yikora, kandi urwego rukurikira rushobora gutunganywa nyuma yurwego ruringaniye.Ibi birasaba resin kugira viscosity nkeya kugirango irusheho kuringaniza no koroshya imikorere.Kugeza ubu, ubwiza bwa resin burasabwa kuba munsi ya 600 CP · s (30 ℃).

(2) Kugabanuka gukira ni nto.Intera iri hagati ya molekile isukuye ni intera yingufu za van der Waals, hafi 0.3 ~ 0.5 nm.Nyuma yo gukira, molekile zirahuza, nintera ya intermolecular kugirango igire imiterere y'urusobekerane ihinduka intera ya covalent, hafi 0.154 nm.Biragaragara, intera iri hagati ya molekile igabanuka mbere na nyuma yo gukira.Intera ya intermolecular yinyongera ya polymerisiyonike izagabanuka kuri 0.125 ~ 0.325 nm.Muburyo bwo guhindura imiti, C = C ihinduka CC, uburebure bwumubano bwiyongera gato, ariko umusanzu muguhindura intera yimikoranire hagati ni muto cyane.Kubwibyo, kugabanuka kwijwi nyuma yo gukira byanze bikunze.Mugihe kimwe, mbere na nyuma yo gukira, imvururu ziba zifite gahunda, kandi kugabanuka kwijwi nabyo bibaho.Ibi ntibibangamiye cyane uburyo bwo kugabanya imiterere, bizatanga imihangayiko yimbere kandi byoroshye kuganisha kumiterere, kurugamba no gucamo ibice byicyitegererezo., Kandi bigira ingaruka zikomeye kubice byukuri.Kubwibyo, iterambere ryibintu bigabanuka ni ikibazo nyamukuru gihura na SLA resin muri iki gihe.

(3) Umuvuduko wo gukira urihuta.Mubisanzwe, ubunini bwa buri cyiciro ni 0.1 ~ 0.2 mm, bushobora gukomera kumurongo mugihe cyo kubumba.Bifata amagana kugeza ibihumbi kugirango ushimangire igice cyarangiye.Kubwibyo, niba igikomeye kigomba gukorwa mugihe gito, igipimo cyo gukira ni ngombwa cyane.Igihe cyo kumurika urumuri rwa lazeri kugera kumurongo ni murwego rwa microseconds kugeza kuri milisegonda, ibyo bikaba bihwanye nubuzima bwimiterere yishimye ya fotoinitiator yakoreshejwe.Igipimo gito cyo gukira ntikigira ingaruka gusa ku gukiza, ariko kandi kigira ingaruka ku buryo butaziguye imikorere yimashini ibumba, bityo biragoye gukoresha mubikorwa byubucuruzi.

(4) Kwaguka guke.Muburyo bwo kubumba, resin yamazi ihora itwikiriye igice cyakize cyakazi kandi irashobora kwinjira mubice byakize, bigatuma resin yakize yaguka, bigatuma ubwinshi bwigice bwiyongera.Ukuri kurugero rushobora kwemezwa gusa niba kubyimba kwa resin ari bito.

(5) Ubukangurambaga bukabije.Kuberako SLA ikoresha urumuri rwa monochromatique, uburebure bwumurongo wa fotosensitif resin na lazeri bigomba guhura, ni ukuvuga, uburebure bwumurambararo wa lazeri bugomba kuba hafi bushoboka kugeza igihe kinini cyo kwinjirira kwinshi kwifoto yumubyimba.Muri icyo gihe, uburebure bwumurambararo wibikoresho bya fotosensitif bigomba kuba bigufi, ibyo bikaba bishobora kwemeza ko gukira bibaho gusa aho imirasire ya lazeri, bityo bikazamura imikorere yibice.

(6) Urwego rwo hejuru rwo gukira.Irashobora kugabanya kugabanuka kwa moderi nyuma yo gukira, bityo bikagabanuka nyuma yo gukira.

(7) Imbaraga nyinshi zitose.Imbaraga nyinshi zirashobora kwemeza ko inzira yo gukira itazana impinduka, kwaguka no gukuramo interineti.
