Lub luag haujlwm ntawm Teflon rhaub hauv 3D Printing: Ua kom lub txaj zoo ib yam
Tso lus
3-D luam ntawv tiam tau loj hlob sai thiab siv dav hauv ntau lub teb nrog rau kev tsim khoom, kev kho mob, thiab kos duab. Qhov kub tswj ntawm lub tshuab luam ntawv txaj ua haujlwm tseem ceeb hauv kev ua kom zoo nkauj luam ntawv. Thiab PTFE warmers tau dhau los ua ib qho kev xav zoo tshaj plaws rau kev khaws cov khoom luam ntawv txaj sov.
Thaum lub sijhawm 3-D txheej txheem luam ntawv, qhov kub ntawm lub tshuab luam ntawv lub txaj yog qhov tseem ceeb rau qhov zoo nkauj ntawm cov khoom luam tawm kawg. Yog tias qhov ntsuas kub tswj tsis raug, nws tuaj yeem ua rau muaj teeb meem tseem ceeb nrog rau kev sib cais interlayer, deformation, thiab tawg tsis xws luag. Qhov no tam sim no tsis muaj kev cuam tshuam zoo tshaj plaws ntawm cov khoom lag luam, txawm li cas los xij tseem txo qis kev tsim khoom.
Teflon warmers tau xaus cov lus teb cua sov zoo nyob rau hauv 3-D luam ntawv lag luam vim tias lawv cov thermal conductivity tseem ceeb thiab qhov kub thiab txias tswj kev muaj peev xwm. Lawv tuaj yeem muab cov cua sov zoo sib xws thiab cov khoom cua sov ntawm lub txaj luam ntawv, ua kom paub tseeb tias qhov chaw luam ntawv tag nrho txuas ntxiv qhov kub thiab txias.
Hauv FDM (fused deposition modeling) 3-D printing, Teflon warmers feem ntau muab tso rau hauv qab lub txaj luam ntawv. Lawv tuaj yeem ua kom sov sov kom ntau npaum li qhov xav tau kub thiab tsim nyog tuav qhov kub ntawm tag nrho cov txheej txheem luam ntawv. Qhov kev ntsuas kub tshwj xeeb no tso cai rau kom tsis txhob muaj deformation vim thermal o thiab contraction, ua kom txhua txheej ntawm cov ntaub ntawv luam tawm yuav tsum nruj me ntsis sib koom ua ke, nyob rau hauv lub sij hawm ntev mus rau ib qho yooj yim thiab ntom pem teb qab ntxiag.
Teflon warmers kuj tseem ua haujlwm tseem ceeb hauv kev kho mob me me raws li tag nrho 3-D tshuab luam ntawv nrog rau SLA (stereolithography) thiab DLP (kev ua haujlwm me me). Lawv tuaj yeem muab qhov kub thiab txias nyob ib puag ncig hauv lub tank luam ntawv, ua kom cov ntaub ntawv resin txuas ntxiv zoo tagnrho viscosity thiab flowability tag nrho los ntawm cov txheej txheem kho. Qhov no tsis yog qhov zoo tshaj plaws rau kev txhim kho kev luam ntawv raug, txawm li cas los xij ntxiv rau kev nthuav tawm cov neeg muab kev pabcuam muaj nyob ntawm cov khoom siv kho qhov muag.
