Kulula kakhulu kubo bonke abenzi ukuba baprinte besebenzisa Intambo yePLA. Yinto ebonakalayo ayivelisi ivumba ngexesha lokushicilela, kunjalo ngexabiso eliphantsi, kunjalo biodegradable, kukho imibala eyahlukeneyo kakhulu kwimarike kwaye iyasokola ingxaki encinci yokulwa. Nangona kunjalo, kwezinye iiprojekthi ezithile apho kufuneka sivelise iziqwenga ngokuxhathisa okukhulu kwimpembelelo kunye nobushushu, le nto iyasilela kwaye kuyimfuneko ukubhenela kwiplastiki yeABS.
Ngethamsanqa, abavelisi abaninzi bakhuphe Iifilitha ezithi ngenkqubo yokwenziwa kweekristali ziqokelelwe ezikweni lomlilo zifumane iipropathi zoomatshini ezifanayo nezo ze-ABS. Kule nqaku siza kuhlalutya i-Filaments IPLA INGEO 850 no-870 ukusuka kumenzi waseSpain uSakata3D
Njengoko besesitshilo kuwe nqaku yangaphambili Umenzi we-biopolymer waseMelika i-NaturaWorks kudala esebenza evelisa izinto ezineempawu ezifanayo ne-ABS kodwa zingenaziphene. Kuwo wonke lo nyaka nangaphambili uye waphuhlisa i-PLA athe wayibiza INGEO kunye neyona nto iphambili kulo kukuba unokuthotyelwa inkqubo ekhethekileyo ye-crystallization apho, ngokubeka iinxalenye eziprintiweyo kubushushu ulwakhiwo lwangaphakathi lwezixhobo luhlelwe ngokutsha ngokuguqula iipropathi zalo zoomatshini. Ifezekisa ubunzima obukhulu, ukumelana nefuthe kwaye amalungu angcono ukumelana namaqondo aphezulu obushushu.
Kolu hlalutyo sisebenzise umshicileli kwakhona I-ANET A2 KUNYE. Ngaphandle kokuba uyi Umatshini wokuphela osezantsi (ngexabiso lamaxabiso angaphantsi kwe- € 200 ukuba siyithenga isuka e-China) kwaye singafumani ziphumo zenqanaba eliphezulu kakhulu leenkcukacha, ilungele uninzi lwezinto zentengiso. Une ayizicacisi iimpawu zobugcisa; Ingaprinta ukuya kuthi ga kwi-100 mm / s, ine-bowden-type extruder, i-hotend inokufudunyezwa ukuya kuthi ga kwi-260 ° C, inokuprinta kwisisombululo se-100 microns, inesiseko esishushu kwaye ineprinta enkulu umphezulu (220 * 220 * 270mm).
Ukupakishwa kwe-PLA 3D850 kunye ne-3D870 filament evela kumenzi waseSpain uSakata3D
I-filament iza zipakishwe ngokugqibeleleyo kunye ne-vacuum pack, i-spool esebenza njengenkxaso yenziwe ngeplastikhi ekumgangatho ophezulu kwaye ukubethelelwa kwe-filament kuchanekile kakhulu. Ekuboneni kuqala akukho qhina linokubonwa kwaye ngalo lonke ixesha lokuvela kwethu besingenangxaki malunga noku. Izinto ezinokubambelela okuhle kakhulu phakathi kweengqimba, azibonisi iingxaki zokulwa. Umbala wezinto ezifanayo kunye nokuqaqamba kwamaqhekeza aprintwe ngentambo yesilivere kuyinika ukugqiba okungafaniyo. Ngokubanzi iphendula kakuhle, ngaphandle kokuntsonkotha kwenxalenye eprintiweyo.
La iwebhusayithi yomenzi Yisithende sakhe se-Achilles, ayibonakali kakhulu kwaye inoyilo olujongeka ngathi loluphelelwe lixesha, nangona kunjalo luzalisekisa umsebenzi walo. Singayifumana imathiriyeli, kwaye basinike iiparameter ezisisiseko zokuprinta ngayo.
Uphawu lwenkwenkwezi lwale nto kukuba sinokulubeka ku inkqubo crystallization. Ngenxa yoko kufuneka wabeka amaqhekeza ezo eziko eziko ku ubushushu be-120º Celsius kangangesithuba semizuzu engama-20. Ngalo lonke elixesha sihoye iziqwenga kwaye siqaphele ukuba azikhubazekanga bubushushu xa zingaphakathi ehovini, kwaye akukho nevumba okanye umsi onokusenza singonwabi okanye soyike ukhuseleko ngexesha lenkqubo.
Ekuboneni kokuqala, iziqwenga ezi-crystallized akubonakali ngathi zenze naluphi na utshintsho ngexesha lenkqubo. Nangona kunjalo, uhlalutyo oluneenkcukacha ngakumbi lwakuba lupholile lutyhila oko iinxalenye ziye zaba nzima ngakumbi kwaye zomelela ukuzincama ezinye zezinto eziguqukayo. Nangona amaxwebhu obuchwephesha abonisa ukuba iziqwenga zinokuncipha kancinci ngexesha lekristallisation, iziphumo azinamsebenzi. Iziqwenga zilinganisa i-15x2x2 cm kunye nokwahluka okuhluphekileyo akufikanga kwiimilimitha ezimbalwa
Izigqibo zokugqibela
Siprinte iziqwenga zabo bonke ubukhulu kunye neemilo, siyenza icace loo nto ukwenza iinxalenye kwiPLA 850 okanye i-870 Ingeo akukho nzima ngaphezu kokwenza iindawo ezifanayo kwiPLA esemgangathweni. Ke ngoko, okoko nje umahluko wamaxabiso ungazisi ngxaki, kuyacetyiswa ukuba usebenzise iPLA Ingeo.
El Inkqubo ye-crystallization ilula kakhulu kwaye ayifuni zixhobo zobuchwepheshaNgokunyanga iziqwenga zethu ngale ndlela, siya kuba nakho ukuphucula kakhulu ukusebenza kwabo. Kungenxa yokuba siza kubabeka kwimeko yokubeka esichengeni okanye siqiniseke ukuba bahamba ngcono ngokuhamba kwexesha. Youtube igcwele ngabenzi abangenisa iziqwenga eziprintiwe ngale filament kuvavanyo lwe-craziest onokucinga ngalo, ayinakuphikwa umgangatho we-filament I-PLA 850 okanye i-870 Ingeo iphezulu kakhulu kwi-PLA esemgangathweni.
Okokugqibela, mdumise Umgangatho ophezulu wexabiso / ixabiso le-SAKATA3D filamentsSijongene nomenzi wobuchwephesha kakhulu ngezinto ezisemgangathweni kunye nenkonzo yabathengi enomona. Musa ukukhohliswa yimbonakalo yewebhusayithi yabo, ukuba ubuza kuluntu loMenzi uyakuqonda ukuba uluvo ngokubanzi luyahambelana neli nqaku.
