3D FDM vs resin: uthelekiso olusebenzayo

Xa uqwalasela ukhetho phakathi kwe-3D FDM kunye ne-resin, umahluko omkhulu ubonakala ngokukhawuleza: I-resin iphezulu kwiinkcukacha kunye nokuguda., ngelixa i-FDM ibonelela ngokomelela okusebenzayo kunye neefomati ezinkuluKwi-FDM, kuqhelekile ukusebenza kunye nobude obuphezulu be-0,10-0,20 mm; I-resin ihla kakhulu, inamaleko amancinci kakhulu azoba iinkcukacha ezincinci "ngeglasi yokukhulisa".

Ngokumalunga nesantya, kuxhomekeke kwisicelo. Kwizinto ezinkulu, i-FDM inokugqiba ngokukhawuleza kwaye igcine imveliso eqhubekayo kunye nokucoca okuphakathi. Ngentlaka, ixesha umaleko ngamnye liyafana kuzo zonke iitekhnoloji zokuqikelela (i-DLP/LCD), kodwa ubude bomaleko kunye nokulungiswa kwasemva kokwenza bandise umsebenzi. Ukuyibeka ngokulula: Ukuba ujongene namancinci, amaqhekeza amahle kakhulu, ukulinda kufanelekile.Ukuba uhlanganisa iiprototypes ezinkulu, i-FDM liqabane lakho.

Inkangeleko	Intlaka (SLA/DLP/LCD)	IFilament (FDM/FFF)
Ubude obuqhelekileyo bomaleko	Intle kakhulu, iinkcukacha ezigqithisileyo	Imidiya, iileya ezibonakalayo
Ukugqitywa komphezulu	Igudile kwaye ilinganayo	Ukuba inamagquma, ifuna isanti.
Umthamo woshicilelo	Ilinganiselwe ngomphanda	Ngokuqhelekileyo badala
Emva kokulungiswa	Hlamba + ukunyanga kwe-UV	Ukhetho lwesanti / ukupeyinta

Abo bashicilela iiminiatures, iimodeli zabalinganiswa, okanye izinto eziethe-ethe badla ngokukhetha iresin ngeso sizathu. "bonisa imeko yesimo" olufikelelayo. Ngakolunye uhlangothi, ukuveliswa kweengxenye zemihla ngemihla, ii-casings, inkxaso okanye iiprototypes eziphakathi / ezinkulu zihambelana kakuhle ne-FDM ngenxa yokusebenza kakuhle kunye neendleko.

Iindleko kunye nokugcinwa: kufuneka ugcine engqondweni

Kwinqanaba lokungena, kukho oomatshini be-FDM abafikelelekayo kunye ne-filament kumaxabiso athandwayo ngekhilogram, ngelixa i-resin iqala kumaxabiso aphezulu ngelitha kwaye ifuna izixhobo ezithile (isikhululo sokuhlamba, izixhobo zokunyanga, izinto ezisetyenziswayo). Ibenchmark eqhelekileyo kwimarike... I-FDM njengokhetho olunexabiso eliphezulu/umlinganiselo wevolumu, ekubeni i-resin yeyona inyusa ixabiso lezinto kwiyunithi nganye yomthamo oshicilelweyo.

Ukugcinwa kwe-FDM kubandakanya ukucoca imilomo, ukugcina ipleyiti yokwakha, kunye nokujonga ukuhamba kwe-extruder. I-resin extrusion ifuna ukuqwalaselwa ngenyameko kwi-hopper, ukuhluzwa kwe-resin, ukugcinwa kwesikrini (kwimeko ye-LCDs), kunye nolawulo olufanelekileyo lwenkunkuma kunye nokulahlwa kwezixhobo emva kokulungiswa. Ngaphezu koko, i izinto zokukhusela (iiglavu, imaski) kunye nomoya owaneleyo wongeza kwi-equation.

Inqaku eliphambili kule 3D FDM vs resin dilemma: abasebenzisi abaninzi bakhomba ixabiso resin njengomqoboNgelixa baxabisa i-filament kwibhalansi yayo yonke, xa ukugqiba kunye neenkcukacha zibaluleke kakhulu, iindleko ezongezelelweyo zinokuthethelelwa ngokupheleleyo.

Ukhuseleko, emva kokulungiswa kunye nokusingqongileyo

I-Filament idla ngokulunge ngakumbi kwiindawo zasekhaya ngenxa ye ubuthi obuphantsi yokuphathwa kwayo. I-resin ibandakanya amavumba, ukuchaphaza okunokwenzeka, kunye nesidingo sokukhusela ulusu kunye nokuphefumla. I-post-processing in resin ibandakanya ukuhlamba (umzekelo, kunye ne-isopropyl alcohol) kunye nokunyanga kwe-UV; kwi-FDM, i-post-processing igxile kwisanti kunye nokupeyinta ukuba ujonge ukufihla iileya okanye ukuphumeza ubuhle obugqityiweyo.

Ngokumalunga nokuzinza, kukho iifilaments ezifana nePLA ezivela kwizibonelelo ezivuselelekayo kunye Ziyakwazi ukubola phantsi kweemeko zoshishino. Iintlaka zisalela emva kulo mba kwaye zivelisa inkunkuma ekufuneka ilawulwe ngokufanelekileyo. Ukusetyenziswa kweekhemikhali ekucoceni kunye ukusetyenziswa kwamandla yezigaba zokunyanga.

Enye i-nuance ebonakalayo kwi-3D yethu ye-FDM vs uthelekiso lwe-resin: ngenxa yokupakishwa kweentsimbi, iziqwenga ze-FDM zinokuba ne-porosity yangaphakathi kwaye zingabi namanzi ngokupheleleyo ukuba inkqubo ayilungiswanga; Okwangoku, ezinye iireyini ziphathwa kukukhanya kwelanga ngokuthe ngqo ekuhambeni kwexesha, nto leyo ethintela ukufaneleka kwazo ukuba zisetyenziswe ngaphandle. Yonke itekhnoloji ine "Achilles heel" yayo kwaye kungcono ukuyamkela ukuze uphephe ukungathandeki.

Izicelo ezicetyiswayo kunye neemeko zokusetyenziswa

I-FDM ifanelekile prototypes ngokukhawuleza, stands, izindlu, iindawo ezisecaleni kunye nezinto zokudlalaNgokukodwa xa ubungakanani bubalulekile kwaye ukugqibezela okupolishwe kakhulu akubalulekanga. Umlinganiselo wayo weendleko ukuya kumthamo wenza ukuba ilungele imfundo kunye neendibano zocweyo eziphindaphindwa rhoqo. Ukufumana eminye imizekelo esebenzayo, bona usetyenziso lwe-3D yoshicilelo.

I-resin ivakalelwa kanye ekhaya amancinci, izacholo, amazinyo, iimodeli zonyango kunye prototypes ezikumgangatho ophezuluXa kukho imizobo emihle, imikrolo, okanye iijiyometri ezigqithisileyo, umtsi obonakalayo uyabonakala. Abantu abaninzi abashicilela amanani kunye neziqwenga apho yonke i-micron ibala itshintshela kwi-resin "eyongezelelweyo" kwisiphumo sokugqibela.

Abanye abasebenzisi, emva kokuzama ukuvelisa amanani aneenkcukacha eziphezulu kunye nomshicileli wenjongo ye-FDM ngokubanzi, bafumanisa xa bezama umshicileli we-resin we-8K ukuba inkcazo ikwiligi eyahlukileyo ngokupheleleyo; bachaza ukugqiba kwe-FDM nge-primer njengokuba "nembonakalo efana nodongwe," ngelixa i-resin inikezela imiphetho ebukhali kunye neempawu ezicocekileyoNangona kunjalo, i-FDM ihlala ingumatshini omkhulu weeprojekthi ze-DIY kunye neendawo ezisebenzayo zemihla ngemihla.
