3D luam ntawv resin nthuav dav

Thawj theem ntawm txoj kev tshawb fawb no yog tsom mus rau kev xaiv ib lub monomer uas yuav ua lub hauv paus rau cov polymer resin. Lub monomer yuav tsum kho tau los ntawm UV, muaj lub sijhawm kho luv luv, thiab muaj cov khoom siv kho tshuab zoo uas tsim nyog rau kev siv siab dua. Pab neeg, tom qab sim peb tus neeg sib tw, thaum kawg tau txiav txim siab rau 2-hydroxyethyl methacrylate (peb tsuas yog hu nws HEMA).

Thaum cov monomer raug kaw rau hauv, cov kws tshawb nrhiav tau teem sijhawm nrhiav qhov zoo tshaj plaws photoinitiator concentration nrog rau tus neeg sawv cev blowing kom haum rau HEMA. Ob hom photoinitiator tau raug sim rau lawv qhov kev txaus siab los kho nyob rau hauv tus qauv 405nm UV teeb uas feem ntau pom muaj nyob rau hauv feem ntau SLA systems. Cov photoinitiators tau ua ke hauv qhov sib piv 1: 1 thiab sib xyaw ua ke ntawm 5% los ntawm qhov hnyav rau qhov tshwm sim zoo tshaj plaws. Tus neeg sawv cev blowing - uas yuav siv los pab txhawb kev nthuav dav ntawm HEMA lub cellular qauv, ua rau 'foaming' - yog qhov nyuaj me ntsis kom nrhiav tau. Ntau tus neeg sawv cev sim tsis yaj lossis nyuaj rau stabilize, tab sis pab pawg neeg thaum kawg tau txiav txim siab rau tus neeg sawv cev blowing tsis yog ib txwm siv nrog polystyrene-zoo li polymers.

Cov khoom sib xyaw ua ke tau siv los tsim cov photopolymer resin kawg thiab pab pawg tau ua haujlwm ntawm 3D luam tawm ob peb qhov tsis nyuaj CAD tsim. Cov qauv tau luam tawm 3D ntawm Anycubic Photon ntawm 1x nplai thiab cua sov ntawm 200 ° C rau txog kaum feeb. Qhov kub tau rhuav tshem cov neeg sawv cev tshuab, ua kom cov dej ua npuas ntawm cov resin thiab nthuav qhov loj ntawm cov qauv. Thaum piv rau qhov ntev ua ntej thiab tom qab nthuav dav, cov kws tshawb fawb tau xam cov volumetric nthuav dav txog li 4000% (40x), thawb cov qauv luam tawm 3D dhau qhov txwv ntawm Photon lub phaj tsim. Cov kws tshawb fawb ntseeg tias cov thev naus laus zis no tuaj yeem siv rau cov ntawv thov sib dua xws li aerofoils lossis buoyancy aids vim qhov ceev qis heev ntawm cov khoom nthuav dav.
