Izinto ezenziweyo zepolymer zifuna iimpawu ezahlukeneyo ngokwenjongo yazo, ezinye zazo ezinokubonelelwa ngokusebenzisa iifilaments zepolymer ezenziwe ngezixa ezahlukeneyo zezinto ezininzi.
Isebe le-additive production (AM), ebizwa ngokuba yi-3D printing, iteknoloji yokusika edibanisa izinto zokwenza iimveliso ezisekelwe kwidatha yemodeli ye-3D.
Ngoko ke, inkunkuma eyenziwa yile nkqubo incinci.Itekhnoloji yoshicilelo ye-3D ngoku isetyenziswa kwizicelo ezahlukeneyo, kubandakanywa ukwenziwa komgangatho omkhulu wezinto ezahlukeneyo, kwaye umthamo wokusetyenziswa uya kwanda kuphela.
Le teknoloji ngoku ingasetyenziselwa ukwenza izinto ezinezakhiwo ezinzima, izixhobo ezikhaphukhaphu, kunye noyilo olunokwenzeka.Ukongeza, ukushicilelwa kwe-3D kunenzuzo yokusebenza kakuhle, ukuzinza, ukuguquguquka kunye nokunciphisa umngcipheko.
Enye yezona zinto zibaluleke kakhulu kule teknoloji ibandakanya ukukhetha iiparamitha ezifanelekileyo kuba zinempembelelo enkulu kwimveliso, njengokumila kwayo, ubungakanani, izinga lokupholisa, kunye ne-thermal gradient.Ezi mpawu ke zichaphazela ukuvela kwe-microstructure, iimpawu zayo kunye neziphene.
Ukufundwa komatshini kungasetyenziselwa ukuseka ubudlelwane phakathi kweemeko zenkqubo, i-microstructure, imilo yecandelo, ukubunjwa, iziphene, kunye nomgangatho womatshini wemveliso ethile eprintiweyo.Olu qhagamshelwano lunokunceda ukunciphisa inani lolingo olufunekayo ukuvelisa imveliso ekumgangatho ophezulu.
I-polyethylene ephezulu (i-HDPE) kunye ne-polylactic acid (i-PLA) zizinto ezimbini ezisetyenziswa ngokuqhelekileyo kwiipolymers kwi-AM.I-PLA isetyenziswa njengeyona nto iphambili kwizicelo ezininzi kuba izinzileyo, inoqoqosho, i-biodegradable kwaye inezakhiwo ezigqwesileyo.
Ukurisayikilishwa kweplastiki ngumba omkhulu ojongene nehlabathi;ngoko ke, kuya kuba luncedo kakhulu ukubandakanya iplastiki enokuphinda isetyenziswe kwinkqubo yoshicilelo lwe-3D.
Njengoko imathiriyeli yokushicilela isoloko ifakwa kwi-liquefier, iqondo lobushushu ligcinwa kwinqanaba elifanayo ngexesha lokwenziwa kwe-fused filament (FFF) deposition (uhlobo loshicilelo lwe-3D).
Ngoko ke, i-polymer etyhidiweyo ikhutshwe nge-nozzle ngokunciphisa uxinzelelo.I-morphology yomphezulu, isivuno, ukuchaneka kwejometri, iipropathi zoomatshini, kunye neendleko zonke zichatshazelwa ziinguqu ze-FFF.
Ukuqina, impembelelo ecinezelayo okanye amandla okugoba kunye nesalathiso sokushicilela kuthathwa njengeyona nkqubo ibalulekileyo eguquguqukayo echaphazela iisampulu zeFFF.Kolu phononongo, indlela ye-FFF isetyenziselwe ukulungiselela imizekelo;Imicu emithandathu eyahlukeneyo yasetyenziselwa ukwakha umaleko wesampulu.
a: imodeli yoqikelelo lwe ML yeparamitha yokwandisa i3D abashicileli kwisampulu 1 kunye no 2, b: ML uqikelelo lwe parameter imodeli yokuphucula ye 3D abashicileli kwisampulu 3, c: ML uqikelelo lwe parameter ukulungiselelwa imifuziselo ye 3D abashicileli kwiisampulu 4 kunye 5. Umthombo womfanekiso: Hossain , MI, njl.
Itekhnoloji yoshicilelo ye-3D inokudibanisa umgangatho obalaseleyo weeprojekthi zokuprinta ezingenako ukufezekiswa ngeendlela zemveli zokuvelisa.Ngenxa yendlela ekhethekileyo yokuvelisa yoshicilelo lwe-3D, umgangatho wamacandelo awenziweyo uchaphazeleka kakhulu kuyilo kunye nokuguquguquka kwenkqubo.
Ukufunda ngomatshini (ML) kusetyenziswe ngeendlela ezininzi kwimveliso eyongezelelweyo ukunyusa uphuhliso lonke kunye nenkqubo yokuvelisa.Indlela yoyilo olusekwe kwidatha ephucukileyo ye-FFF kunye nesakhelo sokuphucula uyilo lwecandelo le-FFF sele iphuhlisiwe.
Abaphandi baqikelele ubushushu bombhobho ngoncedo lweengcebiso zokufunda ngomatshini.Itekhnoloji yeML ikwasetyenziselwa ukubala ubushushu bebhedi yoshicilelo kunye nesantya sokushicilela;ubungakanani obufanayo bumiselwe zonke iisampuli.
Iziphumo zibonisa ukuba ukuguquguquka kwezinto kuchaphazela ngokuthe ngqo umgangatho wemveliso yoshicilelo lwe-3D.Kuphela ubushushu obufanelekileyo be-nozzle bunokuqinisekisa ubumanzi obufunekayo bezinto eziphathekayo.
Kulo msebenzi, i-PLA, i-HDPE kunye nezixhobo ezisetyenzisiweyo ze-filament zixutywe kunye ne-TiO2 nanoparticles kwaye zisetyenziselwa ukuvelisa izinto eziprintiweyo ze-3D eziphantsi kwexabiso eliphantsi ngokuthengisa i-filament encibilikisiweyo yokuvelisa iiprinta ze-3D kunye ne-filament extruders.
Iimpawu zeempawu ziyinoveli kwaye zisebenzisa igraphene ukuvelisa i-coating engangeni manzi, enokunciphisa naluphi na utshintsho kwiimpawu ezisisiseko zomatshini wemveliso egqityiweyo.Umphandle wecandelo eliprintiweyo le-3D nawo unokusetyenzwa.
Injongo ephambili yalo msebenzi kukufumana indlela yokufezekisa umgangatho othembekileyo kunye nobutyebi bomatshini kunye nomzimba kwizinto eziprintiweyo ze-3D xa kuthelekiswa nezinto eziprintiweyo ze-3D eziqhelekileyo ezivame ukuveliswa.Iziphumo kunye nokusetyenziswa kolu phando kunokuvula indlela yophuhliso lweenkqubo ezininzi ezinxulumene neshishini.
