Ushicilelo lwe3D
Inkonzo yokuprinta ngokukhawuleza kwe-3D ngokukhawuleza, nokuba ichanekile ngokushicilela i-SLA 3D okanye i-SLS yoshicilelo olomeleleyo, unokuluqonda ngokugqibeleleyo uyilo lwakho ngaphandle kwezithintelo.
Izibonelelo zoshicilelo lwe3D
- Mfutshane ngeXesha lokuHanjiswa -Izahlulo zihlala zithunyelwa ngaphakathi kweentsuku ezimbalwa, zikhawulezisa iterations yoyilo kunye nexesha lokuthengisa.
- Yakha iiJometri ezintsokothileyo-Ivumela ukwenziwa kwamalungu awodwa aneegeometri ezintsonkothileyo kunye neenkcukacha ezichanekileyo ngaphandle kokunyuka kweendleko.
- Ukunciphisa iindleko zeMveliso-Qhuba ukunciphisa iindleko zokuvelisa ngokususa isidingo sezixhobo kunye nokunciphisa abasebenzi.
Yintoni i-3D Prototype?
Ukuprintwa kwe-3D ligama elibanzi elisetyenziselwa ukuchaza imveliso eyongeziweyo, ebandakanya uthotho lobuchwephesha bokukhawulezisa ubuchwephesha obudibanisa izinto ezininzi zokwenza izinto.
Ukuprinta ngokukhawuleza kwe-3D yindlela ekhawulezayo, elula kwaye engabizi kakhulu yokuguqula izimvo zakho zibe yimveliso eyimpumelelo. Ezi prototypes zoshicilelo ze-3D azincedi kuphela ekuqinisekiseni uyilo kodwa zikwafumana imiba kwangoko kwinkqubo yophuhliso kunye nengxelo ngokuthe ngqo kulungiso loyilo, ukuthintela utshintsho olunendleko xa imveliso sele ikwimveliso epheleleyo.
Kutheni ukhetha i-Createproto ye-3D yeNkonzo yokuPrinta?
I-Createproto yingcali kwicandelo lokuvelisa ngokukhawuleza ukuvelisa eTshayina, ukubonelela ngeenkonzo ezahlukeneyo zokuprinta i-3D, kubandakanya ukuprinta kwe-SLA 3D (Stereolithography), ukuprinta kwe-SLS 3D (Selective Laser Sintering).
Kwi-Createproto Sineqela elipheleleyo leenjineli ezinikeleyo kunye nabaphathi beeprojekthi eziza kusebenza kunye nawe ukuqinisekisa uyilo lwe-CAD, imisebenzi yemveliso, ukunyamezelana ngokwamacala, njlnjl. Njengomvelisi wohlobo lobuchwephesha, siyayiqonda imodeli kunye neemfuno zalo naliphi na ishishini. Sizabalazela ukuhlangabezana nawo onke amaxesha achaziweyo ukuhambisa iimveliso kunye neziqinisekiso ezisemgangathweni kubathengi bethu kwihlabathi liphela ngamaxabiso afikelelekayo.
Yintoni ukuprinta kwe-SLA 3D?
Ukuprinta kwe-SLA 3D (Stereolithography) isebenzisa i-laser ye-ultraviolet etsala umphezulu we-resin ye-thermoset engamanzi ukwenza amawaka eelitha ezincinci de kube kwenziwe iinxalenye zokugqibela. Ukhetho olubanzi lwezixhobo, izigqibo eziphezulu kakhulu, kunye nokugqitywa komphezulu womgangatho kunokwenzeka nge-SLA 3D Printing.
Isebenza njani i-SLA 3D yokuPrinta?
- Ukulungiswa kwedatha, imodeli ye3D ingeniswa ngaphakathi kwinkqubo yokucheba isoftware yobunini, kunye namaqumrhu enkxaso ongezwe njengoko kufuneka.
- Ifayile ye-STL iya kuthi emva koko ithunyelwe kushicilelo kumatshini we-SLA, netanki eligcwele ulwelo lwefotosicitive ye-ulwelo.
- Iqonga lokwakha lehliselwa etankini. Umqadi we-UV laser ugxile kwisikeni seelensi secandelo lokuwela ngaphaya komphezulu wolwelo.
- I-resin kwindawo yokuskena iqinisa ngokukhawuleza ukwenza uluhlu olulodwa lwezinto. Nje ukuba umaleko wokuqala ugqityiwe iqonga lehliswe nge-0.05-0.15mm ngomaleko omtsha wentlaka egubungela umphezulu wokwakha.
- Uluhlu olulandelayo lulandelwa ngaphandle, ukuphilisa kunye nokudibanisa i-resin kwinqanaba elingezantsi. Emva koko phinda le nkqubo de inxenye yakhelwe.
Yintoni i-SLS 3D Printing?
Ukuprinta kwe-SLS 3D (i-Stereo Laser Sintering) isebenzisa i-laser eneji ephezulu eneefoyile ezincinci zomaleko ngomaleko ukuvelisa iinxalenye zejometri ezintsonkothileyo nezomeleleyo. Ukuprinta kwe-SLS 3D kwakha iindawo ezomeleleyo ngezixhobo zeNylon ezizeleyo, ezifanelekileyo iiprototypes ezisebenzayo kunye neenxalenye zokusebenzisa.
Isebenza njani i-SLS 3D Printing?
- Umgubo usasazeke kumaleko obhityileyo ngaphezulu kweqonga ngaphakathi kwegumbi elimilisiweyo.
- Xa kufudunyezwa nje ngezantsi kobushushu obunyibilikayo bepolymer, umqadi we-laser ujonga umgubo ngokwendlela yecandelo lomnqamlezo kwaye ubangqule amandla. Umgubo unsintered ixhasa kwisisu kunye cantilever le modeli.
- Xa ukugqitywa kwecandelo elinqamlezileyo kugqityiwe, ukutyeba kweqonga kuyancipha ngomaleko omnye, kwaye i-roller yokubeka isasaza umaleko womgubo ofanayo ngokuxineneyo kuyo ukuze ucofe icandelo elitsha lomnqamlezo.
- Inkqubo iyaphinda-phinda de kube zonke iiseti zenziwe sintered ukufumana imodeli eqinileyo.

Thelekisa ezi zinto zilandelayo ze-SLA kunye ne-SLS Ukukhetha iNkonzo yokuPrinta eyi-3D
Ukuprintwa kwe-SLS 3D kutyebile kwizinto kwaye kunokwenziwa ngeplastiki, isinyithi, i-ceramic, okanye umgubo weglasi ngokusebenza kakuhle. Oomatshini be-Createproto banokuvelisa iinxalenye ezimhlophe zeNylon-12 PA650, PA 625-MF (ezele iMaminerali) okanye i-PA615-GF (Iglasi izalisiwe). Nangona kunjalo, ukushicilelwa kwe-SLA 3D kunokuba yipolymer enamanzi, kwaye ukusebenza kwayo akulunganga njengeplastikhi ye-thermoplastic.
Umphezulu weprototype ngokushicilelwa yi-SLS 3D kukhululekile kwaye kurhabaxa, ngelixa ushicilelo lwe-SLA 3D lubonelela ngenkcazo ephezulu yokwenza umphezulu wamacandelo agudileyo kwaye iinkcukacha zicace gca.
Ukuprintwa kwe-SLA 3D, Ubuncinci beDonga Ubukhulu = 0.02 "(0.5mm); Ukunyamezelwa = ± 0.006 ”(0.15mm) ukuya ku- ± 0.002” (0.05mm).
Ukuprintwa kwe-SLS 3D, Ubuncinci beDonga Ubukhulu = 0.04 ”(1.0mm); Ukunyamezelwa = ± 0.008 ”(0.20mm) ukuya ku- ± 0.004” (0.10mm).
Ukushicilelwa kwe-SLA 3D kunokwakha kwisisombululo esiphakamileyo kunye nobubanzi be-laser beam ubukhulu kunye nezilayi ezicocekileyo zokuphucula iinkcukacha kunye nokuchaneka.
Ukushicilelwa kwe-SLS 3D kusebenzisa izixhobo zokwenziwa kwe-thermoplastic ukuvelisa iinxalenye ezineempawu ezifanelekileyo. I-SLS icutshungulwa ngokulula, kwaye inokugaywa ngokulula, ukubhola, kunye nokucofa ngelixa kusenziwa umatshini wokushicilela we-SLA 3D kufuneka uphathwe ngononophelo kwimeko apho icandelo lophukile.
Ukuxhathisa kweeprototypes zokuprinta i-SLS 3d kwindalo esingqongileyo (ubushushu, ukufuma, kunye nokubola kwemichiza) kuyafana nezinto ze-thermoplastic; I-SLA 3d yokuprinta iiprototypes zichaphazeleka kukufuma kunye nokukhukuliseka kwemichiza, kwaye kwiindawo ezingaphezulu kwama-38 they ziya kuthamba kwaye zikhubazeke.
Amandla okubopha amandla e-SLS 3D angcono kunalawo e-SLA 3D yoshicilelo, apho kukho ii-pores ezininzi ngaphezulu kokubopha kwe-SLS enegalelo kukungena kwe-viscose.
Ukushicilelwa kwe-SLA 3D kulungele ukuveliswa kwakhona kwepatotype master patent, kuba inomphezulu ogudileyo, uzinzo oluhle kunye neempawu ezintle.
Thelekisa ezi zinto zilandelayo ze-SLA kunye ne-SLS Ukukhetha iNkonzo yokuPrinta eyi-3D
Ukuprintwa kwe-3D kukwabizwa ngokuba yimveliso eyongeziweyo, eyakha iinxalenye ngokubeka izinto. Inezibonelelo ezininzi ngaphezulu kweenkqubo zemveli zokuvelisa kodwa ineengxaki zayo. Ukuchithwa kwe-CNC yindlela eqhelekileyo yokukhupha esetyenziselwa izixhobo zokuvelisa, ezenza iindawo ngokusika okungenanto.
Inkqubo yoshicilelo ye-3D ibandakanya ukwenziwa kwamanqanaba ngocingo kusetyenziswa izinto ezinjengee-resin ze-photopolymer resins (SLA), amathontsi e-photopolymer (PolyJet), iplastikhi okanye umgubo wentsimbi (i-SLS / DMLS), kunye ne-plastiki filaments (FDM). Ke ivelisa inkunkuma encinci xa ithelekiswa nenkqubo ye-CNC. Ukuchithwa kwe-CNC kukunqunyulwa kwento yonke, ngoko ke izinga lokusetyenziswa kwezinto liphantsi. Uncedo kukuba phantse zonke izinto zinokufakwa ngomatshini nge-CNC, kubandakanya neeplastiki zobunjineli zemveliso kunye nezinto ezahlukeneyo zesinyithi. Oku kuthetha ukuba i-CNC machining inokuba yeyona ndlela isebenzayo kwiiprototypes kunye nokuphela kokusebenzisa iindawo ezenziwe ngobuninzi ezifuna ukusebenza okuphezulu kunye nokusebenza okukhethekileyo.
Ukushicilelwa kwe-3D kunokudala iinxalenye ezineejiyometri ezinzima kakhulu kunye nemilo engenanto engenakwenziwa ngoomatshini be-CNC, ezinje ngezacholo, ubugcisa, njl njl. I-CNC machining inikezela ngokuchaneka okungaphezulu (± 0.005mm) kunye nomphezulu ogqwesileyo womhlaba (Ra 0.1μm). Oomatshini abaphambili be-5-axis ye-CNC yokugaya banokukwenza ukuchaneka okuphezulu kwamalungu anzima ngakumbi aya kukunceda uhlangabezane nemiceli mngeni yakho enzima kakhulu yokuvelisa.
Ukuprintwa kwe-3D kuvelisa izixa eziphantsi ngaphandle kokusebenzisa izixhobo, kwaye ngaphandle kongenelelo lomntu, ukuze ukujika ngokukhawuleza kunye neendleko eziphantsi kunokwenzeka. Iindleko zokuvelisa zoshicilelo lwe-3D zithengiswa ngokwexabiso lezixhobo, oko kuthetha ukuba iinxalenye ezinkulu okanye ubuninzi obungaphezulu bubiza ngaphezulu. Inkqubo ye-CNC machining inzima, ifuna iinjineli eziqeqeshwe ngokukodwa ukuba zilungiselele kwangaphambili iiparameter zokuqhubekeka kunye nendlela yokuqhubekeka kwamalungu, emva koko kwenziwe machining ngokweenkqubo. Iindleko zokuvelisa ke ziyacatshulwa kuthathelwa ingqalelo abasebenzi abongezelelweyo. Nangona kunjalo, oomatshini be-CNC banokuqhubeka ngokuqhubekekayo ngaphandle kolawulo lomntu, ukuyenza ilungele imiqulu emikhulu.
