Lub luag haujlwm tseem ceeb ntawm Cartridge rhaub hauv 3D Printing thiab Additive Manufacturing

Kev tsim khoom siv ntxiv tau hloov pauv txoj hauv kev tsim thiab tsim, tab sis thev naus laus zis tso cov kev xav tau tshwj xeeb ntawm cov cua sov uas ua rau nws ua tau. Cartridge rhaub yog ib qho tseem ceeb heev rau ntau cov txheej txheem luam ntawv 3D, tshwj xeeb tshaj yog cov uas siv siab - kub thermoplastics, luam ntawv hlau, los yog kho resin. Tab sis cov cua sov siv nyob rau hauv cov xwm txheej no muaj teeb meem uas tsis tu ncua kev lag luam units tsis tau ua nrog. Yuav kom tau txais kev luam ntawv zoo ib yam thiab txhim khu kev qha, koj yuav tsum paub txog cov teeb meem no.

Qhov kub kawg ntawm fused deposition modeling (FDM) tshuab luam ntawv yog ib qho nyuaj tshaj plaws rau kev ua hauj lwm 3D luam ntawv. Txhawm rau kom cov khoom ntws tsis tu ncua, lub tshuab cua sov yuav tsum khaws lub nozzle ntawm qhov kub thiab txias, feem ntau nyob rau hauv ± 1 degree. Lub rhaub yog me me, feem ntau 6 hli dav thiab 20mm mus rau 30mm ntev, thiab nws yuav tsum tau haum rau hauv ib lub rooj sib tham me me nrog lub thermocouple thiab kiv cua txias. The watt density is high because the area that is heated is small. Vim yog lub zog siab ceev thiab qhov chaw me me, lub tshuab rhaub yuav tsum tau ua nrog cov khoom sib txuam ntawm magnesium oxide thiab siab -cov hlau tsis zoo los txo qhov kub kub uas tuaj yeem ua rau cov ntawv luam tawm tsis zoo.

Thaum koj luam tawm hauv cov hlau 3D, xws li xaiv laser melting (SLM) lossis electron beam melting (EBM), koj xav tau lub tshuab cua sov kom sov lub phaj tsim. Txhawm rau kom cov phaj tsim los ntawm kev sib tsoo thiab kom paub tseeb tias cov txheej txheem ua ke zoo, nws yuav tsum tau khaws cia ntawm qhov kub thiab txias, feem ntau ntawm 200℃thiab 500 degree. Cov cua sov feem ntau yog ntev thiab npog tag nrho qhov dav ntawm chav tsev tsim kho. Lawv yuav tsum tau cua sov ib cheeb tsam loj sib npaug. Txhawm rau kom poob cua sov ntawm thaj tsam ntawm lub phaj, tib neeg feem ntau siv ntau -zone cartridge heaters. Cov khoom siv sheath yuav tsum muaj peev xwm tswj tau qhov kub thiab txias yam tsis muaj kev tawg thiab cov hmoov hlau abrasive siv hauv cov txheej txheem.

Lwm qhov kev siv yog nyob rau hauv cov cua sov uas yog siv los luam tawm siab - cov ntaub ntawv ua tau zoo xws li PEKK thiab PEEK. Txhawm rau khaws cov ntaub ntawv no los ntawm warping thiab kom paub tseeb tias cov khaubncaws sab nraud povtseg ua ke, lub chamber yuav tsum nyob nruab nrab ntawm 120℃thiab 200 degree. Cov cua sov yog los ntawm cov khoom siv cua sov ua rau hauv cov phab ntsa ntawm lub chamber. Txhawm rau tshem tawm qhov sib txawv ntawm qhov kub thiab txias uas tuaj yeem ua rau qhov chaw tsis sib haum, cov cua sov yuav tsum tau nthuav tawm kom sib npaug. Koj yuav tsum ua kom cov hlau lead muaj kev nyab xeeb los ntawm cua sov hauv chamber thiab los ntawm txhua qhov condensation uas yuav tshwm sim thaum lub chamber qhib.

Kev paub qhia tau hais tias 3D luam ntawv daim ntawv thov xav tau cov cua sov uas ua kom qhov kub thiab txias heev. Txawm tias qhov kev hloov ntawm 2℃mus rau 3℃yuav ua rau cov khoom tiav tsis zoo. For high-end printers, manufacturers often require heaters with zoned watt density or built-in thermocouples that let you manage the heat at the point of application in a closed loop. Raws li ntau tus neeg xav tau cov tshuab luam ntawv loj dua, muaj qhov xav tau ntau ntxiv rau ultra- ntev cartridge heaters (1000mm thiab ntev dua) uas tuaj yeem ua kom sov sib npaug ntawm cov phaj thiab cov chav nyob thoob plaws lawv qhov dav.

Thaum xaiv lub tshuab rhaub cartridge, cov tshuab luam ntawv thiab cov neeg siv yuav tsum xav txog cov kev xav tau tshwj xeeb ntawm cov txheej txheem luam ntawv. Lub tshuab cua sov uas ua haujlwm zoo rau PLA luam ntawv ntawm 200℃yuav tsis ua haujlwm zoo rau PEEK luam ntawv ntawm 400 degree. Cov ntaub ntawv sheath yuav tsum muaj peev xwm ua haujlwm ntawm qhov kub ntawd. Lub dab dej kub yuav tsum muaj qhov zoo watt ceev. Qhov chaw txias yuav tsum tau ntev txaus kom cov hlau lead muaj kev nyab xeeb los ntawm qhov kub siab hauv chav. Yog tias koj saib xyuas cov khoom no, cov khoom siv hluav taws xob tuaj yeem yog lub hauv paus txhim khu kev qha rau siab - zoo, zoo ib yam khoom siv ntxiv.
