Dab tsi yog cov ntsiab lus tseem ceeb rau kev ntsuas kub thaum lub sijhawm 3D luam ntawv txheej txheem?

Hauv kev hloov pauv sai thoob ntiaj teb ntawm 3-D luam ntawv, qhov ntsuas kub kom raug yog qhov tseem ceeb rau kev ua tiav cov ntawv luam tawm zoo heev. Daim duab 3-D tshuab luam ntawv tab tom loj hlob ib txheej khoom nyuaj ntawm txoj kev ntawm txheej. Nyob rau hauv ib puag ncig dynamic no, kev tswj qhov kub thiab txias ua haujlwm tseem ceeb.
Thermocouples tej zaum yuav yog ib qho khoom siv zoo rau kev ntsuas kub hauv 3-D luam ntawv. Ib qho tseem ceeb tshaj plaws yog taug qab qhov ntsuas kub ntawm lub platform tsim. Lub tsev tsim lub platform xav kom nyob rau ntawm qhov kub zoo tshaj los ua kom muaj tseeb adhesion ntawm thawj txheej ntawm cov khoom luam tawm. Yog tias qhov kub thiab txias tsuas yog qis dhau, cov yas yuav tsis lo zoo, lub ntsiab rau warping lossis delamination. Thermocouples tuaj yeem muab tso rau ntawm lossis ze rau lub platform tsim kom muaj qhov ntsuas kub kom raug. Piv txwv li, ib lub thermocouple txuas nrog rau hauv qab ntawm lub platform tuaj yeem pab khaws qhov kub thiab txias ntawm qee theem hauv kev luam ntawv.
Lwm qhov tseem ceeb tshaj plaws yog taug qab qhov kub ntawm lub extruder. Lub extruder heats cov ntaub ntawv luam tawm mus rau ib qho kev xaiv kub kom nws mus nrog lub drift smoothly. Yog tias qhov ntsuas kub tsuas yog dhau los lossis qis dhau, nws tuaj yeem cuam tshuam rau thawj chav kawm thiab chaw nyob ntawm cov khoom luam tawm. Los ntawm kev siv lub thermocouple nyob rau hauv lub extruder, qhov kub thiab txias yuav tsum tau saib xyuas thiab hloov raws li xav tau. Qhov no tuaj yeem pab ua kom tsis tu ncua extrusion thiab txuag koj cov teeb meem uas suav nrog clogging lossis inconsistent filament mus nrog drift.
Temperature uniformity thoob plaws hauv cov khoom luam tawm kuj yog ib qho tseem ceeb rau kev txiav txim siab. Hauv ob peb 3-D txheej txheem luam ntawv, uas suav nrog fused deposition modeling (FDM), qhov kub ntawm cov txheej txheem luam tawm xav kom ceev faj tswj xyuas kom muaj kev sib raug zoo ntawm cov txheej txheem. Kev soj ntsuam qhov ntsuas kub ntawm qhov txawv ntawm cov khoom tuaj yeem pab cuam tshuam rau txhua qhov versions thiab tso cai rau kev hloov kho. Piv txwv li, yog tias ib cheeb tsam ntawm cov khoom yog txias dua li lwm tus, lub tshuab luam ntawv tshaj tawm los yog extruder kub tuaj yeem hloov kho kom ua rau qee yam cua sov.
Kev taug qab lub sijhawm tiag tiag yog qhov tseem ceeb. 3-D luam ntawv yam feem ntau yog ua haujlwm tsis nres, thiab txhua qhov kub hloov pauv tuaj yeem tshwm sim sai. Muaj cov cuab yeej ntsuas kub ntsuas uas muaj cov ntaub ntawv teev sijhawm tiag tiag tso cai rau kev txav nrawm yog tias tsim nyog. Qhov no tuaj yeem pab txuag koj qhov tsis xws luag thiab ua rau qee yam aa ntaus ntawv. Thermocouples cuam tshuam nrog cov ntaub ntawv tau txais cov khoom siv tuaj yeem muab qhov ntsuas kub tsis nres thiab cov teeb liab yog tias qhov kub siab tshaj qhov zoo.
Calibration thiab kho dua tshiab ntawm qhov ntsuas kub ntsuas gadget yog qhov tseem ceeb. Tsis tu ncua calibration ntawm cov thermocouples guarantees qhov tseeb nyeem. Tsis tas li ntawd, qhov ntsuas qhov ntsuas kub yuav tsum tau kuaj xyuas thiab tswj xyuas kom paub tseeb tias nws txoj haujlwm zoo. Qhov no suav nrog kev ntxuav cov thermocouples thiab xyuas seb puas muaj kev puas tsuaj lossis hnav. Hauv kev xaus, qhov tseem ceeb tshaj plaws rau kev ntsuas qhov kub thiab txias hauv chav kawm ntawm 3-D luam ntawv yam muaj xws li taug qab cov txheej txheem tsim thiab extruder kub, ua kom qhov kub tsis sib xws, kev taug qab ntawm lub sijhawm, thiab txoj cai calibration thiab kho dua tshiab. Thermocouples tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev nthuav qhia cov ntaub ntawv ntsuas kub kom raug los pab sau cov ntawv zoo 3-D.
