Kuv tau nyob hauv qhov kev lag luam no ntev txaus kom pom ntau txhiab tus zoo nkauj Metal Rapid Prototype qhov tuaj tawm ntawm cov phaj tsim - zoo meej geometry, cov khoom siv tshuab zoo heev ntawm daim ntawv - tsuas yog saib lawv ua tsis tiav ntawm theem tsis muaj menyuam. Tus neeg thov hu, ntxhov siab, hais tias "Nws zoo li zoo nyob hauv lub rooj sib tham." Thiab kuv yuav tsum nco ntsoov lawv: ib feem tsis tiav kom txog thaum nws muaj kev nyab xeeb siv qhov twg nws tseem ceeb tshaj plaws.
HauvSLS 3D Printing Servicethiab hlau additive manufacturing, post-kev ua haujlwm tsis yog polishing thiab kho cua sov xwb. Rau kev kho mob, zaub mov, lossis ib daim ntawv thov kev tswj hwm, kev ua kom tsis muaj menyuam yog qhov kawg, tsis yog - kauj ruam sib tham hauv kev ua haujlwm. Kho nws raws li kev xav tom qab yog ib txoj hauv kev ceev tshaj plaws los hlawv lub sijhawm, nyiaj txiag, thiab kev ntseeg siab.
Kev Sib Tham Peb Ib txwm Muaj: Thaum twg yog ib feem tiag "Tiav"?
Txhua tus kws tshaj lij engineer thaum kawg muaj qhov kev paub no: lub tshuab luam ntawv tsuas yog qhov pib.
Koj tsim ib feem, optimize qhov tsim orientation, khiav cov ntawv luam tawm, tshem tawm cov kev txhawb nqa, kev kho cua sov rau kev ntxhov siab, thiab tom qab ntawd ua tiav qhov chaw. Ntau pab neeg nres qhov ntawd thiab xav tias lawv ua tiav.
Tab sis hauv kev txhim kho cov cuab yeej kho mob, "ua tiav" txhais tau hais tias ib feem tau raug lees paub tias tsis muaj menyuam thiab tseem muaj kev nyab xeeb tom qab ntau lub voj voog kom tsis muaj menyuam. Qhov ntawd hloov txhua yam.
Kuv tau muaj cov neeg siv khoom hais rau kuv, "Tsuas luam nws - peb mam li ua kom tsis muaj menyuam tom qab." Rau lub lis piam thiab ob peb qhov kev lees paub tsis tau ua tiav tom qab, lawv rov qab thov kev pab. Zaj lus qhia yeej ib txwm zoo ib yam: tsim thiab npaj rau kev ua kom tsis muaj menyuam txij hnub ib, tsis yog qhov kawg checkbox.
Defining the Traditional Post-Txoj Kev Pipeline
Tus txheej txheem hlau additive workflow zoo li no:
Txhawb Kev Tshem Tawm thiab De-Powdering - Tshem tawm cov Scaffolding thiab cov hmoov xoob uas tsis yaj.
Kev kho cua sov / Kev Nyuaj Siab - Txo cov kev ntxhov siab sab hauv loj uas SLM / SLS qhov chaw nqa.
Nto Finishing - Bead blasting, CNC machining, electropolishing, thiab lwm yam, kom ua tau raws li qhov yuav tsum tau muaj Ra tus nqi thiab cov tsos.
Cov kauj ruam no yog lub hauv paus. Ib tug zoo kev cai hlau qauv tsim executes lawv nrog precision thiab tag nrho cov ntaub ntawv. Tab sis rau kev kho mob thiab siab - daim ntawv thov kev ua tau zoo, cov kav dej no ua tsis tiav yam tsis muaj kev ua kom tsis muaj menyuam.
Case rau Sterilization raws li Kev Tshaj Tawm Kawg -Txoj Kev Ua Haujlwm
Kev ua kom tsis muaj menyuam tsis yog ntxuav xwb - nws yog kev puas tsuaj tag lossis tshem tawm tag nrho cov kab mob uas siv tau. Hauv kev tswj hwm kev lag luam, qhov no txhais tau tias ua tiav qhov Kev Pov Hwm Sterility (SAL) ntawm 10⁻⁶.
"Clean" txhais tau tias tsis pom cov av. "Sterile" txhais tau tias tsis muaj cov kab mob muaj sia nyob uas tuaj yeem ua rau kis kab mob.
Hauv Metal Rapid Prototype ua haujlwm rau kev siv kho mob, qhov sib txawv ntawm ob lo lus no tuaj yeem yog qhov sib txawv ntawm kev pom zoo ntawm kev ua lag luam thiab kev sim ua tsis tiav. Cov lattices nyuaj, sab hauv, thiab thaj chaw siab ua rau cov khoom siv ntxiv tshwj xeeb yog qhov nyuaj rau kev ua kom tsis muaj menyuam piv rau cov khoom siv ib txwm siv.
Vim li cas Kev Kho Mob thiab Khoom Noj Qib Industries tsis tuaj yeem hla qhov "Keeb Kawg"
Cov kab mob tsis quav ntsej koj qhov zoo li cas. Lawv nkaum hauv cov hav me me (Ra> 0.8 μm twb muaj kev pheej hmoo), cov hmoov tsis zoo, thiab cov voids sab hauv. Thaum ib daim ntawv biofilm, nws yuav nyuaj heev rau tshem tawm.
Kev tswj hwm lub cev (FDA, EU MDR) kho kom tsis muaj menyuam yog cov txheej txheem tseem ceeb. Koj tsis tuaj yeem lees paub lub cuab yeej yam tsis tau ua pov thawj txoj kev ua kom tsis muaj menyuam ua haujlwm rau koj tus qauv tsim thiab cov khoom siv tshwj xeeb. Qhov no yog vim li cas muaj kev lag luam loj SLS 3D tshuab luam ntawv kho kom tsis muaj menyuam validation raws li ib feem ntawm lawv cov kev pabcuam tseem ceeb.

Koj qhov kev xaiv ntawm SLS 3D Printing Service cuam tshuam li cas rau kev ua kom tsis muaj menyuam
Kev luam ntawv thev naus laus zis thiab cov ntsuas tsis ncaj qha cuam tshuam qhov yooj yim (lossis nyuaj) kom tsis muaj menyuam.
Powder Quality & Particle Size - Cov hmoov pheej yig dua nrog kev sib faib dav tsim cov khoom ntim ntau dua.
Tsim Tsis Muaj - Cov ntawv luam tawm ntau dua (99.5%+) yooj yim los ntxuav thiab ua kom tsis muaj menyuam.
Tsim kom muaj Sterilization (DFS) - Cov kev tawm tswv yim tawm tswv yim, qhov tsawg kawg nkaus qhov loj me, thiab nkag tau rau hauv geometries ua qhov sib txawv loj.
Ib lub tuam txhab kev cai hlau qauv uas nkag siab txog kev kho mob ua haujlwm yuav ua kom zoo rau tag nrho cov saw - tsis yog luam tawm xwb.
Tiag -Lub Ntiaj Teb Scenario
Ib tus neeg siv khoom xav tau lub teeb yuag, ergonomic phais kev xyaum ua haujlwm uas tuaj yeem muaj sia nyob 200+ autoclave cycles. Cov qauv tsim thawj zaug tau luam tawm zoo nkauj tab sis ua tsis tau zoo rau kev ua kom tsis muaj menyuam vim tias cov kab hauv nruab nrog cov dej noo thiab cov seem.
Peb rov tsim dua tshiab nrog txoj hauv kev zoo dua, ntxiv electropolishing, thiab tau txais kev pom zoo ntawm lub voj voog ib puag ncig. Qhov kawg tau dhau tag nrho cov kev sim tshuaj lom neeg, txo qhov hnyav los ntawm 35% piv rau cov tshuab tshuab, thiab tam sim no nyob rau hauv ntau lawm. Cov kauj ruam ua kom tsis muaj menyuam yog qhov uas yuav luag tua qhov project - thiab thaum kawg ua kom tiav.
Cov ntaub ntawv qhia kev: Cov khoom ruaj khov nyob rau hauv Sterilization Stress
Rov ua dua autoclaving (134 degree, saturated steam) stresses cov khoom:
Ti6Al4V: ruaj khov heev. Kev hloov pauv tsawg kawg hauv cov khoom siv kho tshuab txawm tias tom qab ntau pua lub voj voog thaum raug passivated.
316L Stainless Hlau: Zoo heev thaum electropolished. Cov txheej txheem chromium oxide tiv thaiv corrosion.
Dimensional Hloov: Feem ntau<0.05 mm if finishing allowance was designed in.
Nto roughness muaj qhov sib cuam tshuam ncaj qha nrog kev tu kom zoo. Cov khoom kho mob feem ntau tsom Ra Tsawg dua lossis sib npaug li 0.8 μm, nrog ntau qhov chaw tseem ceeb tsom rau Ra 0.2-0.4 μm.
Lub Logistics ntawm Kev Lag Luam Muag Khoom thiab Kev Tswj Xyuas Zoo
Rau lag luam wholesalehlau ceev prototypestsiv mus rau hauv ntau lawm, koj xav tau batch-mus rau-batch sib xws. Qhov no yuav tsum tau kaw - cov txheej txheem nqis, cov phiaj xwm sampling, thiab tag nrho traceability los ntawm hmoov ntau mus rau lub hnab tsis muaj menyuam.
Lub siab - ntim muaj SLS 3D tshuab luam ntawv yuav tsum muaj peev xwm muab tau:
Cov ntaub ntawv pov thawj
Txheej txheem validation qhia
Sterilization validation cov ntaub ntawv (IQ/OQ/PQ)

FAQ
Q: Vim li cas ho tsis feem ntau 3D luam ntawv quotes suav nrog kev ua kom tsis muaj menyuam?
A: Vim tias nws yog kev tswj hwm, daim ntawv thov - cov txheej txheem tshwj xeeb. Ntau tus neeg muab kev pabcuam SLS 3D Printing Service tsom mus rau prototyping thiab tso kom tsis muaj menyuam rau cov neeg siv khoom lossis cov koom tes tshwj xeeb.
Q: Kuv puas tuaj yeem ua kom tsis muaj kab mob hlau nrawm nrawm rau kuv tus kheej hauv tus qauv autoclave?
A: Qee lub sij hawm rau cov geometry yooj yim, tab sis cov lattices complex feem ntau xav tau EtO lossis Gamma. Tsis txhob xav tias - ib txwm siv tau.
Q: Puas yog "post-processing" txhais tau hais tias ib feem yog biocompatible?
A: Tsis yog. Biocompatibility (ISO 10993) thiab kev ua kom tsis muaj menyuam yog cais tab sis muaj feem cuam tshuam. Kev kho deg pab ob leeg, tab sis yuav tsum tau kuaj tag nrho.
