Amafoto ya fotosensitif, azwi cyane nka UV ikiza igicucu kidafite igicucu, cyangwa UV resin (adhesive), igizwe ahanini na oligomer, fotoinitiator na diluent.Mu myaka yashize, resin yunvikana yakoreshejwe muruganda rugaragara rwo gucapa 3D, rutoneshwa kandi ruhabwa agaciro ninganda kubera imiterere yarwo nziza.Ikibazo niki, resinensitive resin ni uburozi?
Gukora ihame rya fotosensitif resin: mugihe urumuri ultraviolet (urumuri rufite uburebure bwumurongo runaka) rurasa kumurongo wa fotosensitif, resin yifotora izabyara ibisubizo bikiza kandi bihinduke biva mumazi bihinduka bikomeye.Irashobora kugenzura inzira yumucyo (SLA Technology) cyangwa kugenzura neza imiterere yumucyo (DLP) kugirango ikire.Muri ubu buryo, urwego rwo gukiza ruba icyitegererezo.
Ibisigarira bifotora bifashishwa cyane cyane mugucapisha icyitegererezo cyiza hamwe nuburyo bugoye bwo gushushanya hamwe nibisabwa cyane kugirango uburinganire bwikitegererezo hamwe nubuziranenge bwubuso, nkibibaho byamaboko, intoki, imitako cyangwa ibice byo guteranya neza.Ariko, ntibikwiriye gucapwa moderi nini.Niba moderi nini zigomba gucapurwa, zigomba gusenywa kugirango zicapwe.Ariko, twakwibutsa ko icapiro ryoroshye kandi risobanutse neza rigomba gukosorwa mugice cyanyuma.Aho guswera bidashobora kugera, gukorera mu mucyo bizaba bibi cyane.
Ibikoresho bifotora ntibishobora kuvuga gusa niba ari uburozi cyangwa bidafite uburozi.Uburozi bugomba kuganirwaho hamwe na dose.Mubisanzwe, ntakibazo nyuma yo gukira bisanzwe.Umucyo wo gukiza urumuri ni matrix resin yo gukiza urumuri.Yiyongereyeho ifoto ya fotinitiator, ikora neza ninyongeramusaruro zitandukanye kugirango ikore urumuri rukiza.
Imikorere ya UV monomer ni ubwoko bwa acrylate monomer ikwiranye na UV ikiza.HDDA ifite ubukonje buke, imbaraga zikomeye zo kuyungurura, ingaruka zo kubyimba kuri substrate ya plastike, kandi irashobora kunoza neza no guteza imbere kwizirika kuri plastike.Ifite imiti irwanya imiti, irwanya amazi nubushyuhe, irwanya ikirere cyiza, umuvuduko ukabije woguhinduka neza.UV monomers ikoreshwa cyane mubitambaro bya UV, wino ya UV, ibyuma bya UV nibindi bice.
UV monomer isanzwe irangwa nubukonje buke nubushobozi bukomeye bwo guhindagurika;Kwizirika neza kuri substrate ya plastike;Kurwanya imiti myiza, kurwanya amazi no kurwanya ubushyuhe;Kurwanya ikirere cyiza;Guhindura neza;Umuvuduko ukabije wo gukiza;Gutose neza no kuringaniza.
UV monomer irashobora gukira gusa mugihe irekuwe nigisubizo cyumucyo numucyo ultraviolet, ni ukuvuga, fotosensitiferi mumashanyarazi adafite igicucu izahuzwa na monomer mugihe ihuye numucyo ultraviolet.Mubyukuri, igicucu kidafite igicucu ntigishobora gukira hafi itarinze kurasa kumurasire ultraviolet.Imirasire ya ultraviolet ituruka kumirasire yizuba isanzwe nisoko ryumucyo.Gukomera UV, byihuse gukira.Mubisanzwe, igihe cyo gukira kiri hagati yamasegonda 10 na 60.Ku zuba risanzwe ryizuba, imirasire ya ultraviolet mugihe cyizuba izakomera, kandi byihuse umuvuduko wo gukira.Ariko, mugihe nta zuba rikomeye ryizuba, hashobora gukoreshwa gusa urumuri rwa ultraviolet.
Hariho ubwoko bwinshi bwa artificiel ultraviolet yumucyo, kandi itandukaniro ryimbaraga naryo nini cyane.Imbaraga nke zirashobora kuba ntoya nka watt nkeya, kandi imbaraga-ndende zishobora kugera kuri watts ibihumbi mirongo.Umuvuduko wo gukiza wibicucu bitagira igicucu byakozwe nababikora batandukanye cyangwa moderi zitandukanye ziratandukanye.Igicucu kidafite igicucu gikoreshwa muguhuza gishobora gukira gusa nimirasire yumucyo.Kubwibyo, igicucu kidafite igicucu gikoreshwa muguhuza gishobora guhuza gusa ibintu bibiri bibonerana cyangwa kimwe murimwe kigomba kuba kiboneye, kugirango urumuri ultraviolet rushobora kunyura no kurasa amazi yometseho;Koresha UV idafite igicucu kuri kimwe hejuru yacyo, funga indege ebyiri, hanyuma ucane itara rya ultraviolet rifite uburebure bukwiye (ubusanzwe 365nm-400nm) n'imbaraga cyangwa itara rya mercure yumuvuduko mwinshi kugirango umurikire.Iyo irasa, birakenewe kurasa kuva hagati kugera kuri peripheri, kandi ukemeza ko urumuri rushobora rwose kwinjira mubice bihuza.
